Current Concepts in the Surgical Management of Haglund’s Deformity

High-Yield Summary

• Haglund’s deformity is a posterosuperior calcaneal prominence causing retrocalcaneal bursitis and insertional Achilles tendinopathy, often refractory to conservative treatment.
• Surgical indications include persistent pain despite 6 months of non-operative care, significant deformity with Achilles insertion involvementand functional impairment.
• Key surgical approaches involve resection of the bony prominence with or without Achilles tendon debridement or augmentation, tailored by the extent of tendon involvement.
• Avoid excessive calcaneal resection to prevent Achilles tendon detachment or weakening; intraoperative fluoroscopy and tendon-sparing techniques optimize outcomes.
• Postoperative protocols emphasize early controlled mobilization balanced with protection of the repair to minimize stiffness and promote tendon healing.

Clinical Fundamentals

Anatomy

The calcaneus’ posterosuperior tuberosity forms the bony prominence implicated in Haglund’s deformity. The Achilles tendon inserts on the posterior calcaneal tuberosity, closely related to the retrocalcaneal bursa, which lies between the tendon and bone. The superficial retro-Achilles bursa lies subcutaneously, contributing to symptomatology when inflamed.

Biomechanics

Excessive pressure from rigid footwear or altered foot mechanics increases friction between the Achilles insertion and the calcaneal prominence, leading to bursitis and tendon degeneration. The deformity alters the normal gliding interface, increasing mechanical stress on the tendon insertion.

Epidemiology

Haglund’s deformity predominantly affects middle-aged adults, with a slight female predominance. It is more common in patients with cavus foot morphology and tight Achilles tendons. Bilateral involvement occurs in up to 20% of cases.

Classification & Diagnosis

Diagnostic Pearls

• Lateral weight-bearing radiographs are essential but must be correlated clinically.
• MRI is critical to assess Achilles tendon integrity and bursal inflammation.
• Avoid over-reliance on Fowler-Philip angle alone; clinical correlation is paramount.
• Differential diagnosis includes insertional Achilles tendinopathy without deformity, retrocalcaneal bursitisand calcaneal stress fractures.

Decision-Making Algorithm

Rationale for Surgical Approach

• Isolated bony prominence without tendon involvement: endoscopic or open calcaneal ostectomy.
• Tendon involvement: open approach with tendon debridement ± augmentation (e.g., flexor hallucis longus transfer).
• Extensive tendon degeneration or rupture: reconstruction with tendon transfer or augmentation.
• Implant choice is generally limited to fixation of tendon transfers or anchors for tendon repair; no hardware is used for bony resection.

Surgical Mastery & Pearls

Step-by-Step Conceptual Overview

1. Patient Positioning and Exposure: Prone or lateral decubitus with a longitudinal or lateral incision medial to the Achilles to protect the sural nerve.
2. Identification and Protection of Neurovascular Structures: Meticulous dissection to avoid sural nerve injury.
3. Bony Resection: Use intraoperative fluoroscopy to guide resection of the posterosuperior calcaneal tuberosity, preserving the Achilles insertion footprint.
4. Tendon Assessment: Inspect Achilles insertion; debride degenerative tissue while preserving viable tendon.
5. Tendon Repair or Augmentation: If partial tears are present, perform side-to-side repair or augment with FHL transfer if >50% tendon involvement.
6. Closure: Layered closure with care to avoid tension on the skin and tendon.
7. Postoperative Immobilization: Initial immobilization in plantarflexion, transitioning to controlled dorsiflexion over 4-6 weeks.

Intraoperative Red Flags

• Excessive resection risking complete Achilles detachment.
• Poor tendon quality requiring augmentation beyond simple debridement.
• Neurovascular compromise, especially sural nerve entrapment.
• Inadequate visualization leading to incomplete bony resection.

Evidence-Based Synthesis

Recent randomized controlled trials and cohort studies emphasize the superiority of combined bony resection with tendon debridement over isolated ostectomy in patients with insertional tendinopathy. Endoscopic calcaneoplasty offers reduced wound complications but is limited to cases without significant tendon pathology. The role of FHL transfer has gained traction for extensive tendon degeneration, with studies demonstrating improved functional outcomes and lower re-rupture rates compared to debridement alone.

Meta-analyses reveal that early controlled mobilization protocols reduce postoperative stiffness and improve tendon healing, challenging traditional prolonged immobilization. However, consensus on optimal rehabilitation timing remains evolving, with ongoing trials investigating biologic augmentation to enhance tendon repair.

Controversy persists regarding the threshold of tendon involvement warranting augmentation, with some evidence supporting conservative debridement in partial tears under 50%, while others advocate for more aggressive reconstruction to prevent recurrence.

Master Class Pro-Tip

Mastery in Haglund’s deformity surgery lies in balancing adequate bony resection with preservation of the Achilles insertion footprint. Utilize intraoperative fluoroscopy dynamically to tailor resection margins precisely. When tendon quality is borderline, err on the side of augmentation with FHL transfer to prevent late rupture. Finally, integrate a multidisciplinary rehabilitation plan emphasizing early, protected motion to optimize tendon remodeling and functional recovery-this nuanced orchestration distinguishes the expert surgeon from the competent.
