Freiberg's infraction: a subchondral bone fatigue fracture. A new surgical treatment.

Abstract

Observations on plantar pressure points suggest that Freiberg's infraction is osteonecrosis of the second or third metatarsal head resulting from a subchrondral bone fatique fracture. A series of 53 cases were successfully treated by deflexion osteotomy of the involved metatarsal head.
