Treatment of Haglund's Deformity in the Foot

Haglund's deformity, often called "pump bump," is a bony enlargement on the posterior superior aspect of the calcaneus (heel bone) where the Achilles tendon inserts. This condition frequently leads to retrocalcaneal bursitis and insertional Achilles tendinopathy, causing significant heel pain and discomfort. It commonly affects active individuals, women wearing high-heeled shoes, and those with high arches or tight Achilles tendons. While not fully understood, contributing factors include genetic predisposition, repetitive pressure from rigid footwear, overuse, and biomechanical issues like excessive supination.

Symptoms typically include a visible and palpable bump on the back of the heel, pain during walking or activity (especially with shoes pressing on the area), swelling, redness, and sometimes blistering or callusing. Pain often worsens with tight shoes or high heels but may ease with open-back footwear. Early recognition is important, as prolonged irritation can lead to tendon degeneration.

• Diagnosis

Diagnosis begins with a thorough clinical history and physical examination. A podiatrist or orthopedic foot specialist palpates the heel for prominence and tenderness while assessing gait and Achilles flexibility. Imaging is essential: X-rays confirm the bony exostosis and evaluate its size and position. MRI or ultrasound may be used to assess soft tissue involvement, such as bursa inflammation or Achilles tendon damage. Differential diagnoses include Achilles tendinosis, stress fractures, or other heel pathologies.

• Conservative (Non-Surgical) Treatments

Conservative management is the first-line approach and succeeds in most patients, particularly when started early. The goal is to reduce inflammation, relieve pressure on the prominence, and address contributing biomechanics. Treatment typically lasts 3–6 months before considering surgery.

Key conservative measures include:

• Footwear modifications**: Patients should avoid shoes with rigid heel counters (e.g., dress shoes, skates, or pumps). Opt for soft-backed, open-heel, or low-heel shoes to minimize friction. This simple change often provides rapid symptom relief.
• Orthotics and padding**: Heel lifts or cups elevate the heel slightly (about 1 cm), reducing Achilles tension. Heel pads cushion the area, while custom orthotics correct high arches or abnormal gait. Arch supports help redistribute pressure.
• Anti-inflammatory measures**: Over-the-counter NSAIDs (e.g., ibuprofen) reduce pain and swelling. Ice application (20 minutes several times daily) is highly effective. Topical creams or gels may also help. Corticosteroid injections can provide temporary relief for bursitis but are used cautiously due to risks like tendon weakening.
• Physical therapy**: Eccentric strengthening and stretching exercises for the gastrocnemius and soleus muscles improve flexibility and reduce tendon load. Manual therapy, ultrasound, and proprioceptive training address muscle imbalances. Shockwave therapy (ESWT) is a valuable non-invasive adjunct, promoting healing in chronic cases.
• Activity modification**: Rest from high-impact activities (running, jumping) and weight management reduce stress on the heel. Many patients experience substantial improvement with consistent adherence to these measures.

Conservative treatment resolves symptoms in a majority of cases, avoiding the need for invasive procedures. However, it does not remove the bony prominence itself—only manages the associated inflammation and irritation.

• Surgical Treatments

Surgery is indicated when conservative measures fail after 3–6 months, symptoms severely impact quality of life, or there is significant tendon degeneration. The primary goal is to resect the bony prominence, excise the inflamed bursa, and debride any damaged Achilles tendon tissue.

• Open surgery** involves a larger incision for direct visualization. The surgeon removes the

Haglund's exostosis, clears the bursa, and repairs or reattaches the Achilles tendon if needed (often using anchors like the SpeedBridge technique). This approach suits complex cases with extensive tendon involvement.

• Endoscopic or minimally invasive techniques** (e.g., endoscopic calcaneoplasty or percutaneous resection) use small portals or incisions. These offer advantages like reduced postoperative pain, smaller scars, lower complication rates, and faster recovery. Procedures such as the Zadek osteotomy may also address biomechanical alignment.

Success rates are high: studies show significant improvements in AOFAS (American Orthopaedic Foot & Ankle Society) scores (around 30+ points) and patient satisfaction exceeding 80–90% in many series. Revision rates are low (around 2–6%). Complications, though uncommon, include infection, wound healing issues, nerve damage, tendon weakness, or recurrence.

• Recovery and Prognosis

Postoperative recovery varies by technique. Open procedures often require 2–6 weeks of non-weight-bearing or protected weight-bearing in a cast or boot, followed by physical therapy. Minimally invasive methods allow earlier mobilization. Full recovery typically takes 3–6 months for daily activities and up to 12 months for high-level sports. Physical therapy focuses on restoring strength, flexibility, and gait.

Most patients return to pre-symptom activity levels with good long-term outcomes. Prevention involves maintaining proper footwear, Achilles flexibility, and healthy weight.

Haglund's deformity treatment starts conservatively with excellent results for many. When needed, modern surgical techniques—especially minimally invasive—provide reliable relief. Consultation with a foot and ankle specialist ensures personalized care tailored to severity, lifestyle, and overall health. Early intervention remains key to optimal outcomes.
