title: Evaluation of scarf osteotomy for management of hallux valgus deformity.
abstract: Hallux valgus is a complex progressive deformity affecting the forefoot. The main pathologic anatomy concerns the first metatarsophalangeal joint, including a varus or medial deviation of the first metatarsal and pronation deformity in the longitudinal axis. The goal of this study was to evaluate a series of consecutive patients over a 2-year period after a scarf osteotomy of the first metatarsal. A scarf osteotomy was performed on 31 consecutive patients with moderate to severe hallux valgus deformity (intermetatarsal angle, 13-22°; hallux valgus angle, 20-44°). Twenty-nine women and 2 men had an average age of 57 years (range, 21-71 years) at the time of surgery. Preoperative and postoperative evaluations included standing anteroposterior and lateral radiographs, American Orthopaedic Foot and Ankle Score (AOFAS) score, physical examination, and foot pressure analysis by weight-bearing ink prints. Patients were evaluated radiographically and clinically in the initial postoperative period (≤1 month), intermediate postoperative period (2-6 months), and final follow-up (12-36 months). Twenty-eight feet were available for analysis. Five of the 28 feet had concurrent surgeries on the lesser toes for hammer-toe correction or preoperative metatarsalgia. Paired Student t test on the 28 feet showed a statistically significant improvement (P<.0001) between pre- and postoperative intermetatarsal angle, hallux valgus angle, and AOFAS score. One foot had recurrence of the hallux valgus deformity. Paired analysis of variance of the 27 feet without recurrence showed a statistically significant improvement in the pre- and postoperative parameters (P<.0001). From this subset, the multiple-comparison Student-Newman-Keuis post hoc test showed a statistically significant (P<.0001) preservation of the correction in the intermediate follow-up period to final follow-up at an average 28 months.
