Arthroscopic resection of talocalcaneal coalitions--a bicentre case series of a new technique

Abstract

Background: Symptomatic tarsal coalitions failing conservative treatment are traditionally managed by open resection. We describe an arthroscopic technique for excising talocalcaneal coalitions and present a retrospective two-surgeon case series of the first eight patients (nine feet).

Methods: Outcome measures include restoration of subtalar movements, return to work and sports, visual analogue pain scales and Sports Athlete Foot and Ankle Scores (SAFAS). Follow-up ranges from 1 to 5.5 years.

Results: Pain and SAFAS improved in 7 patients. Subtalar movements were improved in all feet. All patients achieved early good function but one relapsed requiring subsequent fusions. One posterior tibial nerve was damaged.

Conclusions: Minimal destruction of bone and soft tissues allows early mobilization and minimizes pain. Patient selection and preoperative planning are crucial to avoid relapse and complication. This series from two independent surgeons supports the feasibility and effectiveness of this technique.
