Resection for symptomatic talocalcaneal coalition.

Over a 10-year period, 20 persistently symptomatic talocalcaneal tarsal coalitions were treated with resection. These cases were reviewed at an average of 29 months after treatment. Preoperative computed tomography (CT) scans were obtained in 17 of 20 feet. Good or excellent clinical results were obtained in 77% of patients with resection of coalitions involving one third or less of the total joint surface. Increasing age in this group was not a contraindication to surgery. Four patients had an uncommon varus deformity and were treated with resection. Overall this subgroup had a poorer prognosis.
