Haglund’s deformity, a perplexing and often painful condition of the heel, presents a unique clinical challenge at the intersection of biomechanics, anatomy, and patient lifestyle. Named after the Swedish surgeon Patrick Haglund who first described it in 1928, this pathology is characterized by a prominent, bony enlargement on the posterior-superior aspect of the calcaneus (heel bone). Often colloquially termed “pump bump” due to its association with rigid-backed footwear, its impact extends far beyond a simple cosmetic concern. The treatment of Haglund’s deformity is not a one-size-fits-all endeavor but rather a graduated, strategic approach that escalates from simple lifestyle modifications to intricate surgical intervention, dictated entirely by the severity of symptoms and the failure of prior conservative measures.
The cornerstone of understanding treatment lies in recognizing the condition’s pathophysiology. The bony prominence itself is not inherently painful. Discomfort arises from a cycle of mechanical irritation. The enlarged bone repetitively rubs against the rigid counter of a shoe, leading to inflammation of the retrocalcaneal bursa (a fluid-filled sac between the bone and Achilles tendon) and the subcutaneous bursa (between the skin and tendon). Furthermore, chronic irritation can lead to insertional Achilles tendinopathy, where the tendon fibers attaching to the calcaneus become degenerated and inflamed. Therefore, effective treatment aims not merely to reduce the bump, but to interrupt this cycle of irritation, inflammation, and soft-tissue damage.
The first line of defense, and often sufficient for many patients, is a comprehensive conservative management plan. This multi-pronged strategy seeks to reduce inflammation and minimize pressure. Activity and footwear modification is paramount. Patients are advised to avoid shoes with rigid, constricting backs, opting instead for open-backed footwear like sandals or shoes with soft, padded heel counters. For athletes, particularly runners, a temporary reduction in volume or intensity, especially on inclines which increase heel strike pressure, is recommended. Pharmacological intervention typically involves a course of oral non-steroidal anti-inflammatory drugs (NSAIDs) like ibuprofen to manage acute pain and swelling.
Physical therapy plays a critical role, focusing on improving the biomechanical environment. Therapists may employ modalities such as ultrasound or ice massage to reduce inflammation. More importantly, they prescribe targeted stretching exercises for a tight Achilles tendon complex—gentle, sustained stretches that do not aggravate the insertion point—and strengthening exercises for the entire posterior chain. Addressing contributing factors like calf weakness or poor gait mechanics can reduce strain on the heel. Protective measures are equally vital. Gel heel pads or silicone sleeves can cushion the prominence, while doughnut-shaped pads help offload direct pressure. For some, a temporary period in a walking boot may be necessary to completely immobilize the area and allow acute inflammation to subside.
When inflammation from the Haglunds is severe and persistent, corticosteroid injections may be considered. However, this intervention is approached with significant caution. While injecting into the retrocalcaneal bursa can provide dramatic short-term relief, repeated or misplaced injections into the Achilles tendon itself carry a well-documented risk of tendon rupture. Consequently, many foot and ankle specialists reserve this option for specific cases and often use ultrasound guidance for precise placement.
If 3 to 6 months of diligent conservative care for the Haglund’s deformity fails to yield adequate improvement, surgical intervention becomes a serious consideration. Surgery is reserved for patients with chronic, debilitating pain that impairs daily function and quality of life. The surgical philosophy is twofold: to remove the offending bony prominence (exostectomy) and to address any accompanying pathology in the bursae or Achilles tendon. The specific approach is highly tailored, influenced by the size of the deformity, the degree of Achilles involvement, and the surgeon’s expertise.
The least invasive surgical option is an open or endoscopic exostectomy. In an open procedure, a lateral incision is made alongside the Achilles tendon, the tendon is carefully retracted, and the prominent bone is shaved down with an osteotome or burr. The endoscopic technique, gaining popularity, involves two small portals and a camera, allowing for bone removal with minimal soft-tissue disruption. This approach typically offers faster recovery and less scarring but is not suitable for all deformity shapes or for cases with significant tendon damage.
When the Achilles tendon itself is severely degenerated or partially torn at its insertion, a more extensive procedure is required. A calcaneal osteotomy may be performed, where a wedge of bone is removed from the calcaneus to tilt the heel and reduce the prominence. In the most severe cases of insertional tendinopathy, the damaged portion of the tendon must be detached, the bone debrided and reshaped, and the tendon reattached using suture anchors. This Achilles tendon detachment and reconstruction is a major operation with a prolonged recovery but is necessary when the tendon integrity is compromised.
Regardless of the technique for Haglunds, the post-operative rehabilitation protocol is arguably as critical as the surgery itself. It is a slow, disciplined process. Patients typically spend weeks in a non-weightbearing cast or boot to protect the repair. Gradual weight-bearing is then introduced, followed by a prolonged period of physical therapy focused on restoring range of motion, strength, and eventually, proprioception and sport-specific function. Full recovery, particularly for athletic patients aiming to return to high-impact activities, can take six months to a year. Potential surgical risks, including infection, nerve injury, scar tenderness, persistent pain, and in rare cases, Achilles tendon rupture, must be thoroughly discussed.
The treatment of Haglund’s deformity exemplifies the principles of progressive, patient-centered orthopedics. It begins with a foundation of conservative care aimed at modifying the mechanical conflict between foot and footwear. When this fails, surgery offers a definitive solution, but one that exists on a spectrum from simple bony resection to complex reconstruction. The choice of path is a collaborative decision between patient and surgeon, weighing the severity of anatomical disruption against the demands of the individual’s life. Ultimately, successful treatment requires not just technical skill in the operating room, but a holistic understanding of the condition’s etiology and a committed partnership in the often-grueling journey of recovery.
