Chevron osteotomy for hallux valgus.

A retrospective study of the Chevron osteotomy procedure for hallux valgus was carried out on 112 patients (168 feet) with an average age of 39.7 years (range 19 to 61 years). The average follow-up was 4.4 years (range 13 months to 7.5 years). The preoperative diagnosis was symptomatic hallux valgus. The average preoperative intermetatarsal 1-2 angle was 15.5 degrees (range 11 degrees to 18 degrees) and the hallux valgus angle was 28.1 degrees (range 21 degrees to 42 degrees). The operation was effective in improving symptoms, cosmesis, and function and in decreasing the deformity.
