The Evans Calcaneal Osteotomy Using a Buried K-Wire Technique

Abstract

Lateral column lengthening is a common procedure used to treat stage 2 of posterior tibial tendon dysfunction with acquired flat foot deformity. This was first described by Evans, who used a tricortical iliac crest bone graft in the anterior calcaneus for the correction of flat feet. The Evans osteotomy is a common reproducible osteotomy that offers triplanar correction. We describe a less common operative technique using a buried K-wire to fixate the osteotomy to prevent dorsal subluxation of the distal fragment. Level of Clinical Evidence: Diagnostic Level V. See Instructions for Authors for a complete description of levels of evidence.
