Outcome of the scarf osteotomy in adolescent hallux valgus

Abstract

Purpose We have reported the radiological and clinical outcome of scarf osteotomy in the treatment of moderate to severe hallux valgus among adolescent children. Method Data were collected retrospectively between April 2001 and June 2006. The pre- and post-operative intermetatarsal angle (IMA), hallux valgus angle (HVA) and distal metatarsal articular angle (DMAA) were determined. Patients were followed up for a mean of 37.6 months. Results Thirteen patients with 19 operated feet were available at the time of the latest follow-up. There was significant improvement in the mean post-operative IMA, which was maintained to the last follow-up. There was statistically significant improvement in the 6-week post-operative HVA and DMAA. However, this was lost at the final follow-up. The mean American Orthopaedic Foot and Ankle Society score for the whole group was 80 (54–100). Conclusion This study indicates that scarf osteotomy should be used with caution in symptomatic adolescent hallux valgus, as there is a high recurrence rate.
