title: [Microsurgical treatment of ischemic necrosis of the head of the 2nd metatarsal bone].
abstract: In order to explore a new method to treat the ischemic necrosis of the head of 2nd metatarsal bone in adult, transposition of reversed vascularized metatarsal bone graft was adopted in the treatment of 4 cases, 2 of which were followed up for one and a half years. The postoperative X-ray showed the round head of the 2nd metatarsal bone became round and even density. The clinical observation showed that there was excellent function of metatarsophalangeal joint. It was concluded that the reversed vascularized metatarsal bone graft could provide a reliable blood supply and various osteogenic factors to the avascularized head of the metatarsal bone, and the operation could also debride the joint cavity and carry out decompression.
