Analysis of the components of residual deformity in clubfeet presenting for reoperation.

Abstract

We reviewed the records and radiographs of 125 children with 159 clubfeet reoperated for residual deformity after operative repair (210 reoperations). We concluded that residual forefoot adduction and supination were the most common persistent deformities (present in 95% of the feet) and that these deformities resulted from undercorrection at the time of primary operation. Although not then apparent, the persistent deformities became more evident with growth, and additional treatment became necessary. Undercorrection resulted from not releasing the calcaneocuboid joint and plantar fascia and failure to recognize residual forefoot adduction on the interoperative radiographs at primary operation.
