Correction of Medial Cavus Deformity by Fusion of the First Metatarsocuneiform Joint

Abstract

Six poliomyelitic feet with cavus deformity corrected by fusion of the first metatarsocuneiform joint were reviewed. Postoperative period is too short to draw final conclusion concerning persistent end result, but this procedure proved to be safer, less traumatic, and effective in correcting the deformity. In some instances, however, additional procedures including the fusion of naviculocuneiform joint and tenoplasty in the sense of reinforcing or replacing the weak posterior tibial muscle were found to be necessary in the prevention of planus deformity.
