Outcomes of a Stepcut Lengthening Calcaneal Osteotomy (SLCO) Compared to Evans Calcaneal Osteotomy for Stage IIb Adult-Acquired Flatfoot Deformity:

摘要

Category:HindfootIntroduction/Purpose:Lateral column lengthening is a powerful procedure utilized to correct the associated abduction deformity in stage II flatfoot deformity; however, prior studies have shown complications of nonunion, graft collapse, and lateral column overload with the Evans osteotomy. The Stepcut Lengthening Calcaneal Osteotomy (SLCO) is a z-lengthening calcaneal osteotomy that can correct midfoot abduction while providing inherent stability by creating a large surface area for bony healing. The goal of our study was to compare outcomes in patients undergoing a SLCO versus an Evans osteotomy. It is our hypothesis that patients following a SLCO would have a decreased incidence of nonunion and lateral overload of the foot, and similar improvement in clinical outcome scores.Methods:All consecutive patients from 2006 to 2013 undergoing stage IIB flatfoot reconstruction from our institution’s Foot & Ankle Registry were identified and included. There were 65 Evans & 79 Stepcut patients with...
