Cavovarus Fifth Metatarsal Fractures and Revision Open Reduction Internal Fixation

Proximal fifth metatarsal fractures, specifically zones 2 and 3, are often treated surgically to lower risk of nonunion and shorten recovery and rehabilitation period. However, even with the advancement of surgical strategies, techniques, and implants, nonunions remain a challenge. One notable risk factor for a primary or recurrent Jones fracture is the cavovarus foot. If this is identified and a recurrent fifth metatarsal base fracture occurs, the surgeon should strongly consider addressing the malalignment in addition to revision open reduction internal fixation. This article provides guidelines for treatment of a recurrent fracture or nonunion with a concomitant cavovarus foot deformity. © 2020 Elsevier Inc.
