Cuneiform and cuboid wedge osteotomies for correction of residual metatarsus adductus: a surgical review.

Abstract

Metatarsus adductus is a deformity in which the metatarsals are deviated in the transverse plane when compared with the longitudinal axis of the lesser tarsus. A brief review of the deformity is presented including the causes, radiographic analysis, conservative treatment, and a surgical approach. A series of cases of metatarsus adductus is presented in which a proximal surgical approach consisted of cuneiform and cuboid wedge osteotomies with staple fixation. The described procedure has advantages over the traditional metatarsal wedge osteotomies by providing large cancellous bone-to-bone interfaces for excellent healing potential, easier fixation, sagittal plane stability, and avoidance of the physis at the base of the first metatarsal.
