Arthroscopic Dorsal Closing-Wedge Osteotomy of Metatarsal Head for Management of Freiberg Infraction.

Abstract

Freiberg infraction is a relatively rare osteochondrosis of the lesser metatarsal head. Operative treatment is indicated if conservative treatment fails to relieve the pain. Dorsal closing-wedge osteotomy is a realignment osteotomy of the metatarsal head and neck to redirect the articular surface, allowing the intact plantar cartilage to articulate with the proximal phalanx. The purpose of this technical note is to describe the details of arthroscopic dorsal closing-wedge osteotomy of the metatarsal head for management of Freiberg infraction. Although dorsal closing-wedge osteotomy has been proposed for the treatment of late-stage Freiberg infraction, we reserve this technique for early stages of the disease.
