Calcaneus deformity in spina bifida: results of anterolateral release

Abstract

We reviewed a group of patients with 76 feet treated operatively for a calcaneus or a calcaneovalgus deformity by a simple anterior (tenotomy of the tibialis anterior, extensor digitorum communis and extensor hallucis longus), or anterolateral (associated tenotomy of the peroneus longus and brevis) release. The results were assessed considering bracing and shoewear problems or presence of pressure sores. The mean follow-up time was 4.66 years, and a good result was achieved in 62 feet (81.5%), with 14 poor results in 18.5%. Among the 14 poor results, six deformities have recurred and were operatively treated by the same technique and eight feet developed an equinus deformity requiring a heel cord release.
