Abstract
Purpose: The purpose of this study was to evaluate the radiological and clinical results of modified scarf osteotomy for hallux valgus with lesser metatarsalgia.
Materials and Methods: Total 19 patients (24 feet) were reviewed by medical records and radiographs. All patients were female and the mean age at the time of operation was 46.4 years. The mean follow-up time was 14.8 months. We modified original scarf osteotomy by adding the procedure of closing wedge osteotomy at the medial side of distal fragment for achieving of the supination of the first metatarsal head. Additionally, Akin osteotomy of the first proximal phalanx was done in 16 patients (20 feet) and no lesser metatarsal operation was done. First-second intermetatarsal, hallux valgus and distal metatarsal articular angles were analyzed radiologically before and after the operation. And 3-dimensional CT was used to evaluate the supination of the first metatarsal head. Clinical results were assessed by American Orthopaedic Foot and Ankle Society (AOFAS) score and persistence of lesser metatarsalgia.
Results: First-second intermetatarsal and hallux valgus angles were reduced from the mean pre-operative values of and to and , respectively, 12 months after the operation. And the supination of the first metatarsal head was confirmed by 3-dimensional CT. The mean AOFAS score improved from 41.4 points pre-operatively to 87.2 points at follow-up. Lesser metatarsalgia still remained in 2 patients (2 feet).
Conclusion: Modified scarf osteotomy would be an effective surgical procedure, especially, for achieving downward displacement and supination of the first metatarsal head in hallux valgus with lesser metatarsalgia.
