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.
