Authors studied 24 cases in 18 patients with the hallux valgus deformity treated by Reverdin osteotomy at Department of Orthopaedic Surgery, Wallace Memorial Baptist Hospital from January 1995 to December 1999. Reverdin osteotomy is one of the distal metatarsal osteotomies in the treatment of hallux valgus in adults. We performed Reverdin osteotomy on 24 cases (18 patients) for painful hallux valgus associated with an increased hallux valgus angle (> 35degrees) and first-second intermetatarsal angle(>13 degrees). The results were as follows. 1. The average first-second intermetatarsal angle was 16.8 degrees and average valgus angle was 37.3 degrees, preoperatively. they were corrected to 7.8 degrees and 12 degrees respectively. 2. The metatarsalgia of the great toe was subsided in all cases and they were satisfied with the result of their operations in respect to cosmetically and functionally. Avascular necrosis of capital fragment, nonunion, and dorsal angulation were not developed in any case. But one case had superficial wound infection and delayed union, presumably due to secondary infection.
