Staples and locking plates provide comparable outcomes for fixation of first metatarsal dorsiflexion osteotomies in pes cavovarus

Abstract Background One commonly encountered deformity within the cavovarus foot is plantarflexion of the first metatarsal which may be a primary or secondary deformity. Correcting the plantarflexion may be achieved through a dorsiflexion osteotomy although the optimal fixation device for this osteotomy has not been determined. This clinical study compared the outcomes using staples and locking plates. Methods A retrospective evaluation was performed of 52 feet that had undergone dorsiflexion osteotomy of the first metatarsal as part of a cavovarus foot correction with a minimum follow-up of two years. Data was collected on deformity correction, complications and cost-analysis. Results As a cohort, Meary’s angle improved from 13.4˚ to 7.72˚ (p  Conclusions Both staples and locking plates are effective devices for fixation of the first metatarsal after a dorsiflexion osteotomy in cavovarus foot surgery. They were both able to provide comparable fixation, although staples were less expensive to use in our study.
