Complete subtalar release in resistant clubfeet: a critical analysis of results in 146 cases.

Abstract

A series of 101 patients (146 feet) with resistant clubfoot corrected by complete subtalar release is presented. A detailed rating system was used to evaluate the results. Minimum follow-up was 2 years. Fourteen feet (9.6%) had undergone additional surgical procedures at the time of review, and 101 feet (69%) had excellent or good functional ratings at that time. The mean total ankle motion was 34.2 degrees (range, 8-56 degrees). The better results occurred in feet without previous surgery. Final ankle range of motion was increased by using a special flexed-knee cast with reserve space above the foot. Longer follow-up is needed to determine the optimal age for surgery.
