Anterior Compartment Syndrome in Runners: Causes, Symptoms, Diagnosis, and Treatment

Anterior compartment syndrome (ACS) is a common but often underdiagnosed condition affecting runners, characterized by increased pressure within the anterior compartment of the lower leg. This condition can lead to pain, muscle dysfunction, and, in severe cases, permanent damage if left untreated. Runners are particularly susceptible due to repetitive stress on the lower leg muscles. This essay explores the anatomy, pathophysiology, causes, symptoms, diagnosis, and treatment of anterior compartment syndrome in runners, emphasizing prevention and management strategies.

Anatomy of the Anterior Compartment

The lower leg is divided into four muscular compartments, each enclosed by a tough fascial layer that does not expand easily. The anterior compartment contains:

Tibialis anterior (dorsiflexes the foot),
Extensor digitorum longus (extends the toes),
Extensor hallucis longus (extends the big toe),
Peroneus tertius (everts the foot).

These muscles are responsible for dorsiflexion and toe extension, critical movements in running. The anterior tibial artery and deep peroneal nerve also run through this compartment, making it vulnerable to compression injuries.

Pathophysiology of Compartment Syndrome

Compartment syndrome occurs when pressure within a muscle compartment increases, restricting blood flow and causing ischemia. It can be:

Acute: A medical emergency due to trauma or severe swelling.
Chronic exertional (CECS): Exercise-induced, common in runners.

During running, muscle volume can increase by up to 20% due to blood flow and edema. If the fascia does not expand sufficiently, pressure builds up, compressing nerves and vessels. This leads to pain, weakness, and, in chronic cases, fibrotic changes in the muscle.

Causes in Runners

Several factors contribute to Anterior compartment syndrome in runners:

Overuse and Repetitive Stress – High-mileage runners or those rapidly increasing intensity are at risk.
Biomechanical Abnormalities – Overpronation or excessive supination alters muscle loading.
Footwear and Running Surface – Poor shoe support or hard surfaces increase impact forces.
Muscle Hypertrophy – Strength training without flexibility work can increase compartment pressure.
Dehydration and Electrolyte Imbalance – May contribute to muscle swelling.

Symptoms

Runners with Anterior compartment syndrome typically experience:

Pain – Aching or sharp pain along the anterior shin, worsening with activity and easing with rest.
Tightness or Swelling – The anterior leg may feel tense or visibly swollen.
Numbness or Tingling – Due to nerve compression (deep peroneal nerve).
Weakness in Dorsiflexion – Difficulty lifting the foot, leading to foot drop in severe cases.
Palpable Tenderness – The anterior compartment is tender to touch.

Unlike shin splints (medial tibial stress syndrome), Anterior compartment syndrome pain is localized to the lateral shin and is more intense during exercise.

Diagnosis

Proper diagnosis involves clinical evaluation and specialized tests:

Clinical Examination – Assessing pain on palpation, muscle strength, and nerve function.
Compartment Pressure Testing – The gold standard; measures intracompartmental pressure before and after exercise.
- Normal: <15 mmHg at rest.
- CECS: >30 mmHg post-exercise or >15 mmHg at rest.
MRI or Ultrasound – Can rule out other conditions like stress fractures.
Treadmill Test – Reproduces symptoms to confirm exertional compartment syndrome.

Treatment Options

1. Conservative Management

Rest and Activity Modification – Reducing running intensity or switching to low-impact activities (cycling, swimming).
Physical Therapy – Stretching (tibialis anterior, calf muscles) and strengthening (eccentric exercises).
Orthotics and Proper Footwear – Correcting biomechanical issues with arch support or motion-control shoes.
Anti-inflammatory Measures – Ice, NSAIDs (short-term use to reduce swelling).

2. Surgical Intervention (Fasciotomy)

If conservative treatment fails, a fasciotomy may be necessary. This involves:

Open or Endoscopic Release – Cutting the fascia to relieve pressure.
Success Rate – ~80% of runners return to sport within 3-6 months.
Risks – Infection, nerve damage, or recurrence.

Prevention Strategies

Runners can reduce Anterior compartment syndrome risk by:

Gradual Training Progression – Avoiding sudden increases in mileage or intensity.
Cross-Training – Incorporating strength and flexibility exercises.
Proper Warm-Up and Cool-Down – Dynamic stretches before running, static stretches after.
Hydration and Nutrition – Maintaining electrolyte balance to prevent muscle cramps.
Footwear Assessment – Replacing worn-out shoes and using orthotics if needed.

Anterior compartment syndrome is a significant concern for runners, often resulting from overuse, biomechanical imbalances, or inadequate recovery. Early recognition and appropriate management—whether through conservative measures or surgical intervention—are crucial for preventing long-term complications. Runners should prioritize proper training techniques, footwear, and muscle conditioning to mitigate the risk of ACS. By understanding this condition, athletes and healthcare providers can work together to ensure optimal performance and musculoskeletal health.

The Impact of Ankylosing Spondylitis on the Foot

Ankylosing spondylitis (AS) is a chronic, inflammatory rheumatic disease that primarily affects the axial skeleton, including the spine and sacroiliac joints. However, AS is a systemic condition that can also involve peripheral joints, entheses (sites where tendons or ligaments attach to bone), and even extra-articular structures such as the eyes, heart, and lungs. While much attention is given to spinal manifestations, the foot is frequently affected in AS, leading to significant pain, stiffness, and functional impairment. This essay explores how ankylosing spondylitis affects the foot, including its pathological mechanisms, clinical manifestations, diagnostic challenges, and management strategies.

Pathophysiology of Ankylosing Spondylitis in the Foot

Ankylosing spondylitis is classified as a seronegative spondyloarthropathy, characterized by inflammation, fibrosis, and eventual ossification of affected structures. The disease primarily targets entheses, leading to a condition known as enthesitis. In the foot, common entheseal sites include:

Achilles tendon insertion (calcaneus)
Plantar fascia attachment (calcaneal tuberosity)
Metatarsophalangeal (MTP) joints
Tarsal joints (subtalar, talonavicular, and calcaneocuboid joints)

The inflammatory process begins with immune-mediated infiltration of lymphocytes and macrophages, leading to localized swelling, pain, and eventual structural damage. Over time, chronic inflammation can result in bone erosion, followed by abnormal bone formation (enthesophytes), contributing to stiffness and reduced joint mobility.

Clinical Manifestations in the Foot

1. Enthesitis

Enthesitis is one of the most common foot-related symptoms in Ankylosing spondylitis. The most frequently affected sites are:

Achilles Tendon Enthesitis: Inflammation at the insertion of the Achilles tendon into the calcaneus causes posterior heel pain, swelling, and difficulty walking, especially during the first steps in the morning or after prolonged rest.
Plantar Fasciitis: Inflammation of the plantar fascia near its calcaneal attachment leads to sharp, stabbing heel pain, often worse upon weight-bearing after rest.

2. Arthritis of the Foot and Ankle

Peripheral arthritis occurs in up to 30% of Ankylosing spondylitis patients, with the foot and ankle commonly involved. Key presentations include:

Tarsitis: Inflammation of the tarsal joints (subtalar, talonavicular) causes diffuse midfoot pain, swelling, and stiffness, often mimicking other conditions like rheumatoid arthritis.
Metatarsophalangeal (MTP) Joint Involvement: The first MTP joint is frequently affected, leading to pain and limited toe movement, sometimes resembling gout or osteoarthritis.

3. Dactylitis (“Sausage Toe”)

Dactylitis is a hallmark feature of spondyloarthropathies, characterized by diffuse swelling of an entire toe due to synovitis and tenosynovitis. It most commonly affects the second, third, or fourth toes and can be extremely painful.

4. Structural Deformities

Chronic inflammation and abnormal bone remodeling can lead to structural changes, including:

Pes Planus (Flatfoot): Due to ligamentous laxity and tarsal joint damage.
Hallux Valgus (Bunion): Progressive deformity of the first MTP joint.
Ankylosis (Fusion): In severe cases, chronic inflammation leads to bony fusion of affected joints, significantly impairing mobility.

5. Extra-Articular Foot Manifestations

Nail Changes: Psoriasis-like nail dystrophy (pitting, onycholysis) may occur, especially in patients with overlapping psoriatic arthritis features.
Skin Lesions: Rarely, AS patients may develop plantar pustulosis or keratoderma blennorrhagicum (associated with reactive arthritis).

Diagnostic Challenges

Diagnosing foot involvement in Ankylosing spondylitis can be challenging due to overlapping symptoms with other conditions, such as:

Plantar fasciopathy (mechanical vs. inflammatory)
Gout or pseudogout (acute MTP/tarsal pain)
Rheumatoid arthritis (symmetrical small joint involvement)
Osteoarthritis (degenerative joint changes)

Diagnostic Tools

Clinical Examination: Tenderness at entheseal sites, joint swelling, and restricted motion.
Imaging:

X-rays: May show erosions, enthesophytes, or joint fusion.
MRI: Detects early enthesitis, synovitis, and bone marrow edema.
Ultrasound: Useful for assessing tendon and ligament inflammation.

Laboratory Tests:

Elevated CRP/ESR (indicating inflammation)
HLA-B27 positivity (present in ~90% of AS patients, though not diagnostic alone)

Management Strategies

1. Pharmacological Treatment

NSAIDs: First-line therapy for pain and inflammation (e.g., ibuprofen, naproxen).
DMARDs: Sulfasalazine or methotrexate may help peripheral arthritis but are less effective for axial disease.
Biologics: TNF inhibitors (e.g., adalimumab, etanercept) and IL-17 inhibitors (e.g., secukinumab) are highly effective for enthesitis and arthritis.
Corticosteroid Injections: Local injections into affected joints or entheses can provide short-term relief.

2. Non-Pharmacological Approaches

Footwear Modifications: Supportive shoes with cushioned insoles, arch support, and heel pads reduce pressure on inflamed entheses.
Orthotics: Custom orthoses can correct biomechanical abnormalities (e.g., pes planus).
Physical Therapy: Stretching (Achilles, plantar fascia) and strengthening exercises improve mobility.
Weight Management: Reducing excess body weight decreases mechanical stress on the feet.

3. Surgical Interventions

Surgery is rarely needed but may be considered for severe cases:

Enthesophyte Removal: For refractory Achilles or plantar enthesophytes.
Joint Fusion (Arthrodesis): For painful, unstable tarsal joints.
Bunion Correction: If hallux valgus causes significant disability.

Ankylosing spondylitis significantly impacts the foot through enthesitis, arthritis, dactylitis, and structural deformities. These manifestations contribute to pain, stiffness, and functional limitations, often requiring a multidisciplinary approach for effective management. Early diagnosis and targeted treatment—including NSAIDs, biologics, orthotics, and physical therapy—are crucial in preventing long-term disability. Increased awareness of foot involvement in AS among clinicians can lead to better patient outcomes and improved quality of life for affected individuals. Future research should focus on optimizing therapeutic strategies to mitigate foot-related complications in AS.

Selecting the Right Hiking Shoes

Hiking is a rewarding outdoor activity that allows individuals to connect with nature, challenge themselves physically, and explore breathtaking landscapes. However, the success and enjoyment of a hike largely depend on having the right gear, particularly footwear. Selecting the right hiking shoes is crucial for comfort, safety, and performance on the trail. With numerous options available—ranging from lightweight trail runners to sturdy mountaineering boots—it can be overwhelming to choose the best pair. This essay explores the key factors to consider when selecting hiking shoes, including terrain, fit, materials, support, and personal preferences, to help hikers make an informed decision.

Understanding Different Types of Hiking Footwear

Before selecting hiking shoes, it is essential to understand the different types available and their intended uses.

1. Trail Runners

Trail runners are lightweight, flexible shoes designed for fast-paced hiking on well-maintained trails. They provide excellent breathability and are ideal for day hikes or ultralight backpacking. However, they lack ankle support and durability for rough terrain.

2. Hiking Shoes (Low-Cut)

Hiking shoes are sturdier than trail runners but still lightweight. They offer better traction and support for moderate trails and are suitable for day hikers or those who prefer agility over heavy protection.

3. Hiking Boots (Mid-Cut)

Mid-cut hiking boots provide additional ankle support, making them ideal for uneven terrain and multi-day backpacking trips. They are more durable and weather-resistant than hiking shoes but are slightly heavier.

4. Backpacking Boots (High-Cut)

Designed for heavy loads and rugged terrain, backpacking boots offer maximum ankle support, stability, and protection. They are best for long-distance hikes, off-trail adventures, and carrying heavy packs.

5. Mountaineering Boots

These are specialized boots for technical climbs, ice trekking, and extreme conditions. They are rigid, insulated, and often compatible with crampons.

Choosing the right type depends on the hiking conditions and personal needs.

Key Factors to Consider When Selecting Hiking Shoes

1. Terrain and Hiking Conditions

The type of terrain dictates the kind of footwear needed.

Smooth, Well-Maintained Trails: Lightweight hiking shoes or trail runners are sufficient.
Rocky, Uneven Terrain: Mid or high-cut boots provide better ankle support.
Wet or Snowy Conditions: Waterproof boots with Gore-Tex or similar membranes are essential.
Long-Distance Hiking with Heavy Loads: Sturdy backpacking boots prevent fatigue and injuries.

2. Fit and Comfort

Ill-fitting shoes can lead to blisters, foot pain, and injuries. Consider the following:

Toe Room: There should be a thumb’s width of space between the toes and the shoe’s front to prevent toenail damage on descents.
Heel Lock: The heel should not slip to avoid blisters.
Width: Shoes should accommodate the natural width of the foot without pinching.
Break-In Period: Leather boots often require breaking in, while synthetic shoes are ready to use.

Trying shoes on in the afternoon (when feet are slightly swollen) and wearing hiking socks ensures a proper fit.

3. Support and Stability

Ankle support is crucial for preventing sprains on uneven trails. Low-cut shoes are fine for light hikes, but rough terrain demands mid or high-cut boots. Additionally, arch support should match the hiker’s foot type (flat, neutral, or high arches).

4. Weight

Lighter shoes reduce fatigue and increase speed but may lack durability and protection. Heavier boots offer stability for challenging hikes but can be tiring over long distances.

5. Breathability vs. Waterproofing

Breathable Shoes: Best for warm, dry climates to prevent sweaty feet.
Waterproof Shoes: Necessary for wet conditions but may trap heat.

Some hikers prefer non-waterproof shoes for quick drying, while others prioritize waterproofing for stream crossings and rain.

6. Traction and Outsole

A high-quality rubber outsole with deep lugs (such as Vibram) ensures grip on slippery or loose surfaces. The tread pattern should match the expected terrain (e.g., aggressive lugs for mud).

7. Durability

Leather boots last longer but require maintenance, while synthetic materials are lighter but may wear out faster. Reinforced toe caps and rubber rands enhance longevity.

8. Season and Climate

Summer Hiking: Lightweight, breathable shoes prevent overheating.
Winter Hiking: Insulated, waterproof boots are necessary for snow and cold.

9. Personal Preferences and Foot Health

Individuals with foot conditions (e.g., plantar fasciitis) may need orthotic-friendly shoes. Some hikers prefer minimalist designs, while others prioritize cushioning.

Trying and Testing Hiking Shoes

1. Shop at Specialty Stores

Outdoor retailers with knowledgeable staff can provide expert advice and proper fitting.

2. Test Before Buying

Walk around the store.
Try shoes on an incline (many stores have simulated ramps).
Wear the same socks used for hiking.

3. Consider Online Reviews

Reviews from other hikers can provide insights into durability, comfort, and performance.

Maintaining Hiking Shoes

Proper care extends the lifespan of hiking footwear:

Clean after each hike to remove dirt and debris.
Dry naturally (avoid direct heat).
Apply waterproofing treatments as needed.
Store in a cool, dry place.

Common Mistakes to Avoid

Choosing Fashion Over Function – Aesthetics should not outweigh comfort and support.
Ignoring Fit for Brand Loyalty – Not all brands fit the same; prioritize comfort.
Skipping the Break-In Period – New boots should be worn on short hikes before long trips.
Overlooking Socks – Quality hiking socks enhance comfort and prevent blisters.

Selecting the right hiking shoes is a critical decision that affects performance, safety, and enjoyment on the trail. By considering factors such as terrain, fit, support, and climate, hikers can choose footwear that meets their specific needs. Investing time in research, trying on multiple options, and understanding personal preferences will lead to a better hiking experience. Whether tackling a rugged mountain path or a gentle forest trail, the right shoes make all the difference in ensuring a successful and pain-free adventure.

Final Recommendation

For beginners, a versatile mid-cut hiking boot is often the best starting point, offering a balance of support, durability, and comfort. As experience grows, specialized footwear can be explored based on individual hiking styles and terrains. Happy hiking!

Achilles Tendon Ruptures

Introduction

The Achilles tendon, the largest and strongest tendon in the human body, connects the calf muscles (gastrocnemius and soleus) to the calcaneus (heel bone). It plays a crucial role in walking, running, and jumping by transmitting the force generated by the calf muscles to the foot. Despite its strength, the Achilles tendon is prone to injury, with ruptures being one of the most severe and debilitating conditions. Achilles tendon ruptures (ATRs) are common among athletes and middle-aged individuals engaging in physical activity. This essay explores the causes, risk factors, diagnosis, treatment options, and rehabilitation strategies for Achilles tendon ruptures.

Anatomy and Function of the Achilles Tendon

The Achilles tendon is a fibrous band of tissue approximately 15 cm long, formed by the merging of the gastrocnemius and soleus muscles. It inserts into the posterior aspect of the calcaneus, facilitating plantar flexion (pointing the foot downward). Due to its limited blood supply—particularly in the area 2-6 cm above the heel—the tendon is vulnerable to degeneration and rupture.

Causes and Risk Factors

Achilles tendon ruptures typically occur during sudden, forceful movements that overload the tendon. Common causes include:

Sports Injuries – Sudden acceleration or jumping (e.g., basketball, tennis, soccer).
Trauma – Direct impact or laceration to the tendon.
Degenerative Changes – Chronic overuse or tendinopathy weakens the tendon over time.
Improper Footwear or Training – Poor support or abrupt increases in activity intensity.

Risk Factors:

Age: Most common in individuals aged 30-50 due to decreased tendon elasticity.
Sex: More prevalent in men (male-to-female ratio of 5:1).
Steroid Use: Corticosteroid injections or oral steroids weaken tendons.
Fluoroquinolone Antibiotics: Drugs like ciprofloxacin increase rupture risk.
Obesity and Diabetes: Metabolic conditions impair tendon healing.
Previous Tendon Issues: History of tendinitis or partial tears.

Mechanism of Injury

Achilles tendon ruptures often occur during eccentric loading—when the muscle contracts while lengthening. A classic scenario is a sudden push-off motion (e.g., sprinting) followed by an abrupt stop, causing the tendon to snap. Patients often report a “pop” or feeling of being kicked in the calf, followed by severe pain and difficulty walking.

Clinical Presentation and Diagnosis

Symptoms:

Sudden, sharp pain in the posterior ankle/heel.
Swelling and bruising.
Inability to stand on tiptoes or push off the affected foot.
A palpable gap in the tendon (in complete ruptures).

Diagnostic Tests:

Thompson Test (Simmonds’ Test):

The patient lies prone while the examiner squeezes the calf.
Lack of plantar flexion indicates a rupture.

MRI or Ultrasound:

Confirms the extent of the tear and differentiates partial from complete ruptures.

X-rays:

May rule out avulsion fractures but do not visualize soft tissue well.

Treatment Options

Management depends on the patient’s age, activity level, and severity of injury. Options include surgical repair or non-surgical (conservative) treatment.

1. Non-Surgical Treatment

Immobilization: A cast or walking boot with heel wedges keeps the foot plantarflexed for 6-8 weeks.
Physical Therapy: Gradual strengthening and mobility exercises after immobilization.

Pros:

Avoids surgical risks (infection, nerve damage).
Suitable for sedentary individuals or those with high surgical risks.

Cons:

Higher re-rupture rate (up to 40% vs. 5% with surgery).
Longer recovery time.

2. Surgical Treatment

Open Repair: The surgeon sutures the torn tendon ends together.
Percutaneous/Minimally Invasive Surgery: Smaller incisions reduce complications.

Pros:

Lower re-rupture rates.
Faster return to sports/activity.

Cons:

Risk of infection, nerve damage, or scarring.
Requires post-operative immobilization and rehabilitation.

Rehabilitation and Recovery

Recovery typically takes 6-12 months, with structured phases:

Phase 1 (0-6 weeks): Immobilization & Protection

Non-weight-bearing or limited weight-bearing in a cast/boot.
Gentle ankle movements to prevent stiffness.

Phase 2 (6-12 weeks): Early Mobilization

Gradual weight-bearing and range-of-motion exercises.
Strengthening begins with resistance bands.

Phase 3 (3-6 months): Strengthening & Functional Training

Eccentric exercises (e.g., heel drops) to rebuild tendon strength.
Low-impact activities (cycling, swimming).

Phase 4 (6+ months): Return to Sport/Activity

Sport-specific drills and plyometrics.
Full recovery depends on adherence to rehab.

Complications

Re-rupture: More common with non-surgical treatment.
Deep Vein Thrombosis (DVT): Due to immobilization.
Chronic Pain or Weakness: If rehab is incomplete.

Prevention Strategies

Proper Warm-Up: Dynamic stretching before activity.
Gradual Progression: Avoid sudden increases in training intensity.
Footwear: Supportive shoes with adequate cushioning.
Eccentric Strengthening: Reduces tendon degeneration risk.

Achilles tendon ruptures are significant injuries requiring prompt diagnosis and appropriate treatment. While surgical repair offers lower re-rupture rates, conservative management may be suitable for certain patients. Rehabilitation is crucial for restoring strength and function. Preventive measures, including proper training techniques and footwear, can reduce rupture risk. Understanding the causes, treatments, and recovery process ensures optimal outcomes for individuals affected by this debilitating injury.

Accessory Navicular

Introduction

The accessory navicular (AN) is one of the most common accessory ossicles of the foot, present in approximately 4-21% of the population. It represents a developmental variation of the tarsal navicular bone and is often asymptomatic. However, when symptomatic, it can cause medial foot pain, particularly in adolescents and young adults. This condition is frequently associated with posterior tibial tendon dysfunction (PTTD) and flatfoot deformity.

Anatomy and Embryology

Normal Navicular Bone

Located on the medial midfoot, articulating with the talus, cuneiforms, and cuboid.
Serves as an attachment site for the posterior tibial tendon (PTT), which supports the medial longitudinal arch.

Accessory Navicular

An extra bone or cartilaginous remnant adjacent to the navicular.
Classically found posteromedial to the navicular tuberosity.
May be bilateral in up to 50% of cases.

Embryological Basis

Develops from a secondary ossification center that fails to fuse with the primary navicular.
Genetic predisposition may play a role.

Classification (Geist System)

Type	Description	Clinical Significance
Type I	Small sesamoid bone within the PTT (~5-10%)	Usually asymptomatic
Type II	Oval-shaped ossicle connected via fibrocartilage (~50-60%)	Most commonly symptomatic (due to stress at synchondrosis)
Type III	Fused ossicle (cornuate navicular) (~30%)	May cause bony prominence and irritation

Clinical Presentation

Symptoms

Medial midfoot pain (worsens with activity, improves with rest)
Tenderness over the navicular prominence
Swelling and redness (if inflamed)
Flatfoot deformity (if PTT dysfunction develops)

Risk Factors

Adolescents and young athletes (especially runners, dancers)
Foot overpronation
Trauma or repetitive stress

Diagnosis

Physical Examination

Palpable bony prominence medial to the navicular.
Pain on resisted foot inversion (due to PTT irritation).
Single-leg heel raise test (assesses PTT integrity).

Imaging

X-rays (Weight-bearing AP, Lateral, Oblique)
- Confirms presence and type of AN.
- Assesses foot alignment (e.g., pes planus).
MRI
- Evaluates synchondrosis stress reaction, PTT pathology, or bone edema.
Ultrasound
- Dynamic assessment of PTT function.

Differential Diagnosis

Posterior tibial tendonitis
Medial plantar nerve entrapment
Tarsal coalition
Stress fracture of the navicular

Management

A. Conservative Treatment (First-Line for Most Cases)

Activity Modification
- Avoid high-impact activities.
Footwear Modifications
- Arch-supportive shoes (e.g., motion control shoes).
- Orthotics (UCBL orthosis, medial heel wedge).
Physical Therapy
- PTT strengthening (e.g., resisted inversion exercises).
- Calf stretching (gastrocnemius-soleus complex).
Medications
- NSAIDs (e.g., ibuprofen) for pain and inflammation.
Immobilization
- Walking boot or cast (for acute exacerbations).

B. Surgical Treatment (If Conservative Measures Fail After 6 Months)

1. Kidner Procedure (Excision + PTT Reattachment)

Indications: Type II AN with PTT dysfunction.
Technique:
- Remove accessory bone.
- Reattach PTT to the navicular.
Success Rate: ~80-90%.

2. Simple Excision (For Type II Without PTT Dysfunction)

Indications: Painful prominence without instability.

3. Arthrodesis (For Severe Flatfoot with Arthritis)

Rarely needed.

Postoperative Care

Non-weight-bearing for 2-4 weeks.
Gradual return to activity (8-12 weeks).

Prognosis and Complications

Prognosis

Most improve with conservative care.
Surgery has good outcomes in refractory cases.

Complications

Persistent pain (if PTT remains dysfunctional).
Wound healing issues (due to thin medial skin).
Recurrence of symptoms (rare).

Conclusion

The accessory navicular is a common anatomical variant that may become symptomatic due to mechanical stress or PTT dysfunction. Type II is most frequently associated with pain.

Key Takeaways

Conservative management (orthotics, PT, NSAIDs) is first-line.
Surgery (Kidner procedure) is effective for refractory cases.
Early diagnosis prevents long-term PTT dysfunction and flatfoot deformity.

Future research for an accessory navicular may explore minimally invasive techniques and biologic augmentation for PTT repair.

Abebe Bikila: The Legendary Barefoot Marathon Runner

Abebe Bikila, the Ethiopian long-distance runner, is one of the most iconic figures in the history of marathon running. Known for his incredible victory at the 1960 Rome Olympics—where he ran barefoot—Bikila became a symbol of resilience, determination, and African athletic excellence. His achievements transcended sports, inspiring generations of athletes across the world. This essay explores Bikila’s early life, his historic Olympic triumphs, his impact on long-distance running, and his enduring legacy.

Early Life and Background

Abebe Bikila was born on August 7, 1932, in the small village of Jato, Ethiopia. Growing up in a rural setting, he developed endurance and strength from an early age, often running long distances as part of his daily life. Unlike many modern athletes who train with advanced equipment, Bikila’s early running experiences were shaped by necessity—he frequently ran barefoot, which later became a defining feature of his career.

Bikila’s introduction to formal athletics came relatively late. He joined the Imperial Bodyguard, an elite unit of the Ethiopian military, where his running talent was discovered by Swedish coach Onni Niskanen. Recognizing Bikila’s potential, Niskanen trained him rigorously, preparing him for international competition.

The 1960 Rome Olympics: A Barefoot Triumph

Bikila’s rise to global fame came at the 1960 Summer Olympics in Rome. Initially, he was not the favorite to win the marathon, as Ethiopia had no strong history in long-distance running at the time. However, Bikila’s performance would change that perception forever.

The Decision to Run Barefoot

A few days before the race, Bikila’s running shoes—provided by Adidas—caused blisters during training. Rather than risk discomfort, he made the bold decision to run barefoot, just as he had done in his youth. This choice stunned spectators and commentators, as no modern Olympic marathoner had attempted such a feat.

The Race Itself

The marathon course in Rome was grueling, passing historic landmarks such as the Appian Way and the Arch of Constantine. Bikila ran with a steady, controlled pace, staying close to the lead pack. In the final kilometers, he broke away from Moroccan runner Rhadi Ben Abdesselam and sprinted to the finish line.

Bikila won the gold medal with a world-record time of 2:15:16.2, becoming the first Sub-Saharan African to win an Olympic gold medal. His victory was not just a personal achievement but a historic moment for Africa, signaling the continent’s emergence as a powerhouse in long-distance running.

Symbolism and Global Impact

Bikila’s barefoot run carried deep symbolism. It represented humility, natural athleticism, and defiance against the notion that African athletes lacked sophistication. His victory challenged stereotypes and proved that greatness could come from unexpected places.

The 1964 Tokyo Olympics: Defending His Title

After his triumph in Rome, Bikila faced new challenges. Just six weeks before the 1964 Tokyo Olympics, he underwent an emergency appendectomy. Many doubted he could recover in time, let alone compete at an elite level. However, Bikila defied expectations once again.

This time, he wore shoes—a practical decision given the harder road surfaces in Tokyo. Despite his recent surgery, he dominated the race, finishing with a new world record of 2:12:11.2 and becoming the first athlete to win back-to-back Olympic marathons. His victory cemented his status as one of the greatest marathoners of all time.

Tragedy and Later Life

Bikila’s career took a tragic turn in 1969 when he was involved in a car accident near Addis Ababa. The crash left him paralyzed from the waist down, ending his running career. Despite this devastating setback, Bikila remained active in sports, participating in archery and table tennis at the 1970 Stoke Mandeville Games (a precursor to the Paralympics).

He also became a national hero in Ethiopia, admired for his perseverance. However, his health deteriorated, and he passed away on October 25, 1973, at the age of 41. His funeral was attended by thousands, including Emperor Haile Selassie, who declared a national day of mourning.

Legacy and Influence

Abebe Bikila’s impact extends far beyond his Olympic medals. He inspired future generations of African runners, including legends like Haile Gebrselassie, Kenenisa Bekele, and Eliud Kipchoge. His success paved the way for East African dominance in long-distance running, a trend that continues today.

Cultural and Political Significance

Bikila’s victories occurred during a period of African decolonization, making him a symbol of pride and independence. His wins demonstrated that African athletes could compete—and excel—on the world stage.

The Abebe Bikila Award

In his honor, the Abebe Bikila Award was established to recognize outstanding lifetime achievements in long-distance running. The annual award celebrates athletes who embody Bikila’s spirit of perseverance and excellence.

Memorials and Tributes

Statues of Bikila stand in Addis Ababa and at the Tokyo Olympic Stadium, ensuring that his legacy endures. His story has been told in books, documentaries, and films, keeping his memory alive for new generations.

Abebe Bikila’s journey from a rural Ethiopian village to Olympic glory is a testament to human resilience and determination. His barefoot victory in Rome remains one of the most iconic moments in sports history, symbolizing the triumph of the underdog. Beyond his athletic achievements, Bikila’s legacy lies in his ability to inspire millions, proving that greatness is not defined by resources but by passion and perseverance.

Even decades after his death, Abebe Bikila’s name continues to resonate as a symbol of excellence, courage, and the enduring spirit of marathon running. His story reminds us that true champions are not just measured by their medals but by the barriers they break and the lives they inspire.

Overview of Plantar Fasciitis

Plantar fasciitis stands as one of the most prevalent causes of heel pain, affecting millions of individuals worldwide and representing approximately 10% of all running-related injuries. This debilitating condition occurs when the plantar fascia, a thick band of connective tissue that spans the bottom of the foot from the heel bone to the toes, becomes inflamed, irritated, or develops small tears. Understanding this condition is crucial for both prevention and effective treatment, as it can significantly impact quality of life and mobility if left unaddressed.

Anatomy and Function of the Plantar Fascia

The plantar fascia serves as the foot’s natural shock absorber and arch support system. This fibrous tissue structure resembles a bowstring, stretching across the arch of the foot and connecting the heel bone (calcaneus) to the metatarsal bones near the toes. During normal walking and running, the plantar fascia stretches and contracts, helping to maintain the foot’s arch while absorbing the impact forces generated with each step. When functioning properly, this remarkable structure can withstand forces equivalent to several times a person’s body weight.

The fascia consists of three distinct bands: the central band, which is the thickest and most commonly affected in plantar fasciitis, and the medial and lateral bands on either side. The central band originates from the medial tubercle of the calcaneus and fans out toward the toes, providing the primary structural support for the longitudinal arch of the foot.

Causes and Risk Factors

Plantar fasciitis typically develops when the plantar fascia is subjected to excessive stress or strain, leading to microscopic tears and subsequent inflammation. This overuse injury rarely occurs from a single traumatic event but rather develops gradually through repetitive stress and mechanical dysfunction.

Several factors increase the likelihood of developing plantar fasciitis. Age plays a significant role, with the condition most commonly affecting individuals between 40 and 60 years old, as the plantar fascia becomes less elastic and more prone to injury over time. Biomechanical abnormalities such as flat feet, high arches, or abnormal walking patterns can create uneven distribution of weight across the foot, placing additional stress on the plantar fascia.

Lifestyle factors contribute substantially to risk. Individuals who spend long periods standing on hard surfaces, such as teachers, factory workers, or healthcare professionals, face elevated risk. Similarly, athletes involved in high-impact activities like running, basketball, or dance are particularly susceptible due to the repetitive stress placed on their feet.

Obesity represents another significant risk factor, as excess body weight increases the mechanical load on the plantar fascia. Poor footwear choices, including shoes with inadequate arch support, worn-out soles, or improper fit, can also contribute to the development of this condition. Additionally, sudden increases in physical activity, particularly among weekend warriors who dramatically increase their exercise intensity without proper conditioning, often trigger plantar fasciitis.

Symptoms and Diagnosis

The hallmark symptom of plantar fasciitis is sharp, stabbing heel pain that is typically most severe with the first steps taken in the morning or after prolonged periods of rest. This characteristic “first-step pain” occurs because the plantar fascia tightens during rest periods, and the sudden stretching upon weight-bearing causes intense discomfort. The pain often improves with initial movement as the tissue warms up and becomes more flexible, but may return after extended periods of standing or walking.

Pain is usually localized to the bottom of the heel, near the arch, though it can radiate along the arch toward the toes. Some individuals describe the sensation as feeling like they are stepping on a stone or having a bruise on the bottom of their heel. The pain typically worsens with barefoot walking on hard surfaces and may be accompanied by stiffness and reduced flexibility in the foot.

Diagnosis primarily relies on clinical examination and patient history. Healthcare providers assess pain patterns, examine foot structure and biomechanics, and may perform specific tests such as the windlass test, which involves dorsiflexing the toes to stretch the plantar fascia. While imaging studies like X-rays or ultrasound are sometimes used to rule out other conditions or assess the extent of tissue damage, the diagnosis is usually made based on characteristic symptoms and physical examination findings.

Treatment Approaches

Treatment for plantar fasciitis typically follows a conservative, multi-modal approach that addresses both symptom relief and underlying mechanical factors. The initial focus centers on reducing inflammation and pain while promoting tissue healing. Rest and activity modification play crucial roles, often requiring temporary reduction in high-impact activities that exacerbate symptoms.

Stretching exercises form the cornerstone of conservative treatment. Calf stretches, plantar fascia stretches, and Achilles tendon stretches help improve flexibility and reduce tension on the plantar fascia. These exercises should be performed consistently, particularly before getting out of bed in the morning and before standing after prolonged sitting.

Footwear modifications and orthotic devices can provide significant relief by improving foot mechanics and reducing stress on the plantar fascia. Well-cushioned shoes with proper arch support, heel cups, or custom orthotics help distribute pressure more evenly across the foot. Night splints, which maintain the foot in a stretched position during sleep, can prevent morning stiffness and pain.

Physical therapy interventions may include manual therapy techniques, ultrasound, ice applications, and strengthening exercises for the intrinsic foot muscles and lower leg. Anti-inflammatory medications can help manage pain and reduce inflammation during acute phases.

For persistent cases that do not respond to conservative treatment after several months, more aggressive interventions may be considered. These can include corticosteroid injections, extracorporeal shock wave therapy, or platelet-rich plasma injections. Surgery is reserved for severe, chronic cases that fail to respond to extensive conservative treatment and significantly impact quality of life.

Prevention and Long-term Management

Prevention strategies focus on addressing modifiable risk factors and maintaining optimal foot health. Maintaining a healthy weight reduces mechanical stress on the plantar fascia, while gradually increasing activity levels allows tissues to adapt progressively to increased demands. Proper footwear selection, including replacement of worn shoes and choosing appropriate shoes for specific activities, plays a vital role in prevention.

Regular stretching and strengthening exercises for the feet and calves can help maintain flexibility and strength, reducing injury risk. Individuals at higher risk should pay particular attention to foot mechanics and consider preventive orthotic devices or supportive footwear.

Plantar fasciitis, while painful and potentially limiting, responds well to appropriate treatment in most cases. Understanding the condition’s underlying mechanisms, recognizing early symptoms, and implementing comprehensive treatment strategies can lead to successful resolution and return to normal activities. With patience, consistency, and proper management, individuals can overcome this common foot ailment and prevent its recurrence.

Chilblain Lupus Erythematosus

Chilblain lupus erythematosus (CHLE), also known as lupus pernio or Hutchinson lupus, is a rare, chronic form of cutaneous lupus erythematosus (CLE) characterized by cold-induced, erythematous to violaceous lesions typically located on acral regions such as the fingers, toes, ears, and nose. First described by Jonathan Hutchinson in 1888, CHLE is considered a subset of chronic CLE and can occur as an isolated condition (primary CHLE) or in association with systemic lupus erythematosus (SLE) (secondary CHLE).

Etiology and Pathophysiology

Genetic Predisposition

Familial CHLE (Hutchinson-Gilford progeria-like syndrome):
- Associated with TREX1 gene mutations, leading to defective DNA repair and interferon (IFN) overproduction.
- Autosomal dominant inheritance pattern.
Sporadic CHLE:
- Linked to cold hypersensitivity and abnormal vascular responses.

Immunological Mechanisms

Type I Interferon Pathway Activation:
- Elevated IFN-? levels contribute to inflammation.
Vascular Dysfunction:
- Cold exposure triggers vasospasm, leading to ischemia-reperfusion injury and inflammatory cytokine release.

Environmental Triggers

Cold and damp climates exacerbate lesions.
Raynaud’s phenomenon is commonly associated.

Clinical Features

Cutaneous Manifestations

Location:
- Fingers and toes (most common)
- Ears, nose, heels (less common)
Morphology:
- Erythematous to violaceous plaques
- Edema, ulceration, and fissuring in severe cases
- Hyperkeratotic or scaly lesions in chronic cases
Symptoms:
- Pain, itching, burning
- Worsening in winter months

Systemic Associations

~20% of CHLE patients develop SLE (secondary CHLE).
Overlap with other autoimmune diseases:
- Discoid lupus erythematosus (DLE)
- Sjögren’s syndrome
- Antiphospholipid syndrome

Diagnosis

Clinical Diagnosis

Based on history of cold sensitivity and characteristic skin lesions.

Histopathology

Perivascular and periadnexal lymphocytic infiltrates
Interface dermatitis (epidermal-dermal junction inflammation)
Dermal mucin deposition

Immunofluorescence

Granular deposition of IgG/IgM and C3 at the dermoepidermal junction (lupus band test).

Laboratory Findings

Antinuclear antibodies (ANA) (positive in ~50% of cases)
Anti-Ro/SSA and anti-La/SSB antibodies (if associated with Sjögren’s)
Cryoglobulins or cold agglutinins (rare)

Differential Diagnosis

Condition	Key Distinguishing Features
Perniosis (chilblains)	No lupus-specific antibodies, no systemic involvement
Acrocyanosis	Persistent cyanosis, no ulceration
Frostbite	History of extreme cold exposure, necrosis
Raynaud’s phenomenon	Triphasic color changes, no fixed lesions
Vasculitis	Palpable purpura, systemic symptoms

Management

A. General Measures

Avoid cold exposure (gloves, warm footwear).
Smoking cessation (worsens vascular dysfunction).
Moisturizers to prevent fissuring.

B. Pharmacological Therapy

First-Line Treatments

Topical corticosteroids (clobetasol propionate 0.05%)
Calcineurin inhibitors (tacrolimus 0.1% ointment)

Second-Line Treatments

Hydroxychloroquine (HCQ) (200–400 mg/day) – gold standard for CLE
Calcium channel blockers (nifedipine 30–60 mg/day) for Raynaud’s

Refractory Cases

Methotrexate (MTX) (7.5–25 mg/week)
Mycophenolate mofetil (MMF) (1–3 g/day)
JAK inhibitors (e.g., baricitinib) – emerging therapy

C. Biologic Therapies (Experimental)

Belimumab (anti-BAFF monoclonal antibody)
Anifrolumab (anti-IFNAR monoclonal antibody)

D. Surgical Management

Laser therapy for persistent telangiectasias.
Debridement for ulcerated lesions.

Prognosis

Primary CHLE: Benign course, often responsive to therapy.
Secondary CHLE (with SLE): Higher risk of systemic complications.
Chronic cases: May lead to scarring, atrophy, or digital deformities.

Conclusion

Chilblain lupus erythematosus is a distinct, cold-induced variant of cutaneous lupus that requires careful differentiation from other acral dermatoses. While topical steroids and hydroxychloroquine remain the mainstay of treatment, emerging biologic therapies offer hope for refractory cases.

Key Takeaways

Chilblain lupus erythematosus is a rare but important diagnosis in patients with cold-induced acral lesions.
Rule out SLE in all Chilblain lupus erythematosus patients due to the risk of systemic progression.
Multidisciplinary care (dermatology, rheumatology) is essential for optimal management.

Future research should focus on targeted therapies modulating the interferon pathway and vascular dysfunction in Chilblain lupus erythematosus.

Wound Dressings for Foot Ulcers

Foot ulcers are a common and serious complication, particularly in patients with diabetes, peripheral arterial disease (PAD), venous insufficiency, and neuropathy. Proper wound care is essential to prevent infections, promote healing, and reduce the risk of amputations. One of the most critical aspects of ulcer management is selecting the appropriate wound dressing, which plays a vital role in maintaining a moist wound environment, controlling exudate, preventing infection, and facilitating tissue regeneration.

Importance of Wound Dressings in Foot Ulcer Management

Foot ulcers require specialized care due to their susceptibility to infection and delayed healing. An optimal wound dressing should:

Maintain a moist wound environment (neither too wet nor too dry)
Absorb excess exudate while preventing maceration
Provide protection from infection
Promote autolytic debridement (removal of dead tissue)
Reduce pain and trauma during dressing changes
Support granulation and epithelialization

The choice of dressing depends on factors such as:

Wound depth and size
Presence of infection
Amount of exudate
Presence of necrotic tissue
Patient’s vascular status

Classification of Wound Dressings

Wound dressings can be broadly categorized into:

A. Passive Dressings

Provide only a covering (e.g., gauze, traditional bandages such as Nupor)

B. Interactive Dressings

Actively interact with the wound to promote healing (e.g., hydrocolloids, hydrogels)

C. Bioactive Dressings

Contain biological agents to enhance healing (e.g., collagen dressings, growth factor dressings)

The Abductory Twist During Gait

Human gait is a complex, coordinated movement involving multiple joints, muscles, and neurological controls. Among the various biomechanical phenomena observed during walking, the abductory twist is a subtle but significant motion that occurs at the foot during the gait cycle. This movement, primarily seen during the transition from heel strike to midstance, involves an outward rotation (abduction) of the forefoot relative to the rearfoot. The abductory twist has been a topic of interest among podiatrists, biomechanists, and physical therapists due to its implications in foot function, pathology, and orthotic management.

Definition and Biomechanics of the Abductory Twist

The abductory twist is a rotational movement of the forefoot that occurs shortly after heel strike, typically during the early stance phase of gait. It is characterized by a slight lateral (outward) rotation of the forefoot while the rearfoot remains stable or continues its natural pronation. This motion is most noticeable when observing gait from behind, where the forefoot can be seen twisting away from the midline of the body.

Phases of Gait and the Abductory Twist

Heel Strike (Initial Contact) – The foot makes contact with the ground, typically with the lateral heel first.
Loading Response (Early Stance) – The foot begins to absorb shock through pronation (a combination of eversion, dorsiflexion, and abduction).
Midstance – The foot transitions from a mobile adapter to a rigid lever for propulsion.
Terminal Stance & Toe-Off – The foot supinates to create a stable push-off.

The abductory twist occurs primarily during the loading response, as the forefoot abducts slightly while the rearfoot pronates. This motion is thought to be a compensatory mechanism to facilitate smooth weight transfer across the foot.

Biomechanical Causes

Several factors contribute to the abductory twist:

Subtalar Joint Pronation: Excessive or prolonged pronation can lead to greater forefoot abduction.
Midtarsal Joint Mobility: The midtarsal joint (Chopart’s joint) allows forefoot adaptation to ground forces.
First Ray Mobility: Hypermobility of the first metatarsal can influence forefoot abduction.
Tibial Internal Rotation: As the tibia rotates internally during stance, the foot may respond with an abductory twist.

Clinical Significance

While the abductory twist is a normal part of gait in many individuals, an exaggerated or restricted twist can lead to biomechanical inefficiencies and pathologies.

Excessive Abductory Twist

An overpronated foot or hypermobile midtarsal joint can cause an exaggerated twist, leading to:

Metatarsalgia (forefoot pain)
Hallux valgus (bunions) due to increased strain on the first metatarsophalangeal joint
Plantar fasciitis from altered load distribution
Shin splints or knee pain due to excessive tibial rotation

Restricted Abductory Twist

A rigid foot with limited motion may exhibit a reduced twist, contributing to:

Lateral foot pain (e.g., fifth metatarsal stress fractures)
Ankle sprains due to poor shock absorption
Hip and lower back compensation

Assessment and Diagnosis

Clinicians assess the abductory twist through:

Visual Gait Analysis – Observing the foot from behind during walking.
Slow-Motion Video Analysis – Capturing the exact timing and degree of forefoot abduction.
Foot Pressure Mapping – Evaluating weight distribution during stance.
Joint Mobility Tests – Assessing subtalar and midtarsal joint motion.

Management Strategies

Treatment depends on whether the abductory twist is excessive or restricted.

For Excessive Abductory Twist

Orthotic Devices: Custom orthotics with medial arch support and forefoot posting can control excessive pronation.
Footwear Modifications: Shoes with motion control and firm heel counters help stabilize the rearfoot.
Strengthening Exercises: Tibialis posterior and intrinsic foot muscle exercises improve dynamic stability.
Taping Techniques: Low-Dye taping can temporarily restrict excessive motion.

For Restricted Abductory Twist

Mobilization Techniques: Joint mobilizations of the midtarsal and subtalar joints improve mobility.
Stretching Exercises: Calf stretches and plantar fascia releases reduce rigidity.
Flexible Footwear: Shoes with a flexible forefoot allow natural motion.

Conclusion

The abductory twist is a critical yet often overlooked component of gait biomechanics. While it serves as a natural adaptive mechanism, deviations from the norm can contribute to various lower extremity disorders. Proper assessment and targeted interventions—such as orthotics, exercises, and footwear modifications—can help restore optimal foot function.

Understanding the abductory twist enhances clinical decision-making, allowing practitioners to address gait abnormalities before they lead to chronic pain or dysfunction. Future research using 3D motion analysis may provide deeper insights into its role in human locomotion.

Final Word

For podiatrists, physical therapists, and sports medicine professionals, recognizing the abductory twist is essential in diagnosing and treating gait-related pathologies. By integrating biomechanical knowledge with evidence-based interventions, clinicians can improve patient outcomes and promote healthier movement patterns.
