Freiberg's Disease in the Emergency Department

Abstract

Freiberg's disease is an avascular necrosis affecting the second, third, or, rarely, the fourth metatarsal head. It is typically a chronic, progressive process, eventually causing pain and loss of normal function of the metatarsophalangeal joint. Normally, patients present to the Emergency Department with atraumatic foot pain, however, as we illustrate with this case, an acute fracture may occur, requiring recognition and appropriate treatment. Our patient presented with acute pain, swelling, and point tenderness of the forefoot after a minor fall. Radiographs revealed a fracture through the head of the second metatarsal and underlying avascular necrosis consistent with Freiberg's disease. Identifying the underlying chronic process was important in understanding how minor trauma resulted in a fracture in this patient.
