The Boc triplane osteotomy seems to restore more physiologic loading of the forefoot in comparison to the Austin procedure, reducing the incidence of painful callus under the second and third metatarsal head.
Hemiarthroplasty of the proximal phalanx and distal oblique metatarsal osteotomy for Grade III hallux rigidus at 2-years followup yielded mixed patient satisfaction and unsatisfactory radiographic outcome.
Triplanar distal osteotomy is a safe procedure for mild-to-moderate hallux valgus deformity. It allows shortening and plantar displacement of the first metatarsal while correcting the intermetatarsal angle. However, complications such as dorsiflexion and excessive shortening of the first metatarsal have been associated with distal osteotomy. We describe a new device, designed by one of the authors (P.R.), that enables precise positioning of the Kirschner guide wire for the osteotomy cuts.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
