Scarf versus long chevron osteotomies for the treatment of hallux valgus: A prospective randomized controlled study

Background: The aim of this study is to compare scarf osteotomy and long chevron osteotomy in treatment of hallux valgus deformity regarding operative time, power of correction and complications. Design: A prospective randomized controlled comparative trial. Methods: 48 cases with hallux valgus were divided randomly in 2 groups (21 treated by scarf and 22 treated by long chevron osteotomy and 5 were missed during follow up), average age 36 years, follow up time was average of 25.9 months. Patients were assessed clinically, radiologically, and functional scoring system of American College of Foot and ankle Surgeons (ACFAS) was used both pre and postoperatively. Results: Operative time was 69 min in scarf group compared to 63 min to long chevron group, radiological correction showed no statistically significant difference between both groups while functional improvement in ACFAS score was in favour of long chevron group 69.1% compared to scarf group 57.5% Conclusions: Both osteotomies possess almost identical corrective power of the IMA (intermetatarsal angle) and similar clinical outcomes with slightly shorter operative time and subjective technical simplicity for the long chevron osteotomy.
