ABSTRACT
Avascular necrosis of the first metatarsal head is uncommon. It is most often seen following a distal metatarsal osteotomy for hallux valgus. Although many cases may be subclinical, it is a powerful cause of failure of bunion surgery. Avascular necrosis of the first metatarsal head results in a series of events that begins with phases of avascularity; revascularization, with or without collapse; and reossification. Collapse may result in degenerative change of the metatarsophalangeal joint. We have recently experienced a case of avascular necrosis of the first metatarsal head.
