Metatarsal head restoration versus dorsal closing-wedge osteotomy in the treatment of advanced-stage Freiberg's disease.

Purpose: Freiberg's disease is mostly characterized by osteonecrosis of second metatarsal head and is widely seen in adolescent women. Metatarsal head restoration technique is a novel surgical procedure intended to protect intact articular surface and regenerate avascular bone under cartilage. This study aimed to evaluate and compare the results and clinical outcomes of metatarsal head restoration technique with those of dorsal closing-wedge osteotomy technique in patients with advanced-stage Freiberg's disease.
