Preliminary Anatomical and Surgical Assessment of Combined Percutaneous Resection and Proximal Medial Gastrocnemius Release vs Historical Controls in Treating Haglund syndrome: A Mixed Prospective-Retrospective Study.

Abstract

Background: Haglund syndrome is characterized by heel pain associated with posterosuperior calcaneal exostosis, insertional Achilles tendinopathy, and retrocalcaneal bursitis. When conservative treatments fail, surgical intervention is required. This study aims to evaluate the effectiveness of a combined surgical approach, integrating percutaneous resection of the calcaneal exostosis and proximal medial gastrocnemius release (PMGR) using the Barouk technique in treating Haglund syndrome. The goal is to assess whether this approach offers superior clinical outcomes compared to percutaneous resection alone.

Methods: We prospectively enrolled 224 patients undergoing combined percutaneous resection and PMGR, divided into group A (n = 106; with Achilles-plantar complex contracture) and group B (n = 118; without contracture) based on passive dorsiflexion testing. Outcomes were compared to 2 historical retrospective control groups treated with resection only: group 1 (n = 124; with contracture) and group 2 (n = 135; without contracture). All prospective patients received the combined treatment regardless of contracture status. Patients with body mass index >30 were excluded. The Foot Function Index (FFI) and Victorian Institute of Sport Assessment-Achilles (VISA-A) Questionnaire scores were collected at baseline and 3, 6, and 12 months.

Results: Groups A and B improved a mean 30 ± 5 FFI points and 40 ± 7 VISA-A points at 12 months (both P < .001). When compared to historical controls who underwent resection alone, the combined treatment groups showed statistically superior outcomes at all follow-up intervals (P < .05). However, these comparisons are limited by the nonconcurrent, unmatched study design.

Conclusion: This mixed prospective-retrospective study suggests potential benefits of adding Achilles-plantar complex lengthening to percutaneous calcaneal resection. However, the nonrandomized design, historical controls, and lack of patient/outcome assessor masking significantly limit causal inference. Although the combined approach showed statistically superior outcomes compared with historical controls, these findings should be considered hypothesis-generating pending validation in randomized controlled trials.

Level of evidence: Level III, retrospective-comparative cohort.
