BACKGROUND: The purpose of this study was to review outcomes of patients treated for symptomatic talocalcaneal coalition with resection and interposition of fat graft. METHODS: A retrospective review was performed on all patients who underwent surgical treatment for symptomatic talocalcaneal coalition over a 13-year period. Ninety-three feet were treated with excision and fat graft interposition by 6 surgeons. All patients underwent a chart review. Patient's outcome was assessed at the last follow-up using the American Orthopaedic Foot and Ankle Society Hindfoot scale. Postoperative computed tomography scans were available for 20 feet. RESULTS: Forty-nine feet had follow-up of at least 12 months and had a score obtained through the American Orthopaedic Foot and Ankle Society Hindfoot scale. At an average of 42.6 months of follow-up, the average score obtained was 90/100 (excellent). The postoperative computed tomography scans demonstrated 1 recurrence (3%), which was treated with repeat excision. An additional patient was reoperated for failure to excise the coalition completely. Eleven patients (34%) underwent a subsequent surgery to correct the alignment of the foot. To the best of our knowledge, none of the patients excluded because of short follow-up had repeat surgery or recurrence. CONCLUSIONS: A symptomatic talocalcaneal coalition can be treated with excision and fat graft interposition, and achieve good to excellent results in 85% of patients. Patients should be counseled that a subset may require further surgery to correct malalignment. LEVEL OF EVIDENCE: Level IV-case series.
