title: Freiberg's infraction of the second metatarsal head with formation of multiple loose bodies.
abstract: Freiberg's infraction is an osteonecrotic disease process that most often involves the head of the second metatarsal. Establishing a diagnosis can be difficult early in the disease course, mimicking such pathologic processes as stress fracture, septic joint infection, tumors, metatarsalgia, various arthritic diseases, etc. A review of the literature reveals many treatment options and many theories of its etiology. The clinical signs and symptoms, review of the etiologies, radiographic presentation, and conservative and surgical treatments of this disease are presented. A case history and treatment summary of a patient afflicted with Freiberg's infarction involving the second metatarsophalangeal joint of the right foot is presented. Treatment consisted of evacuation of multiple loose bodies from the joint, resection arthroplasty of the diseased joint, and insertion of a total joint prosthesis.
