Abstract:
A 74-year-old Japanese woman who underwent Mann's procedure with fibular sesamoidectomy for left hallux valgus 21 years ago complained of left hallucis pain. She was diagnosed with iatrogenic hallux varus and hammer toe deformities. Metatarsophalangeal joint arthrodesis and shortening oblique osteotomy were performed. After surgery, the hallux valgus angle improved from -28° to 0°, and the intermetatarsal angle between the first and the second metatarsus improved from 0° to 6°. The Japanese Society for Surgery of the Foot RA foot and ankle scale improved from 73 to 81 points. She could walk without pain and sustained no deformity at 4 years after the surgery.
