Freiberg's infraction --- treatment with metatarsal neck dorsal closing wedge osteotomy: report of two cases.
Freiberg's infraction is a disease of avascular necrosis that most commonly involves the head of the second or third metatarsal. Several mechanisms have been proposed for its pathogenesis, but stress overloading is the most widely accepted etiology. Nonoperative treatment is thought to be effective in the early stages but not in the late stages of the disease. The methods of operative treatment for symptomatic Freiberg's infraction remain controversial. We report two cases of late stage Freiberg's infraction treated by metatarsal neck dorsal closing wedge osteotomy with good results, and we infer that this operation may be recommended for patients with symptomatic Freiberg's infraction in whom conservative treatments have little effect.
