Equinus Deformity as a Factor in Forefoot Nerve Entrapment

Abstract

Forefoot nerve entrapments are common, and they are usually mistakenly categorized under the misnomer of “Morton’s neuroma.” Although the complete etiology of these forefoot entrapments is still not known, exogenous mechanical factors must be considered when patients present with clinical signs of forefoot nerve entrapment. It has been well established that equinus deformity can increase plantar forefoot pressures. This article provides a brief overview of equinus deformity as it relates to forefoot pathology, specifically, its mechanical contribution to forefoot nerve entrapment, and the use of endoscopic gastrocnemius recession for the treatment of forefoot nerve entrapment.
