Scarf Osteotomy in Treating Hallux Valgus: Clinical and Radiographical Outcome and Technical Notes

IntroductionScarf osteotomy can be a technically demanding procedure and early reports have shown high complication rates. Proponents, however, suggest that this type of osteotomy is versatile and allows for both translation and angulation correction of the hallux valgus (HV) deformity. The purpose of this study was to evaluate the clinical and radiological results of the scarf osteotomy procedure performed in our hospital.Materials and methodsWe retrospectively reviewed 31 feet in 25 patients with an average follow-up duration of 16 months (range: 6-30 months).ResultsOn the latest follow up, 77% of the patients were satisfied with the result, with an average postoperative American Orthopaedic Foot and Ankle Society score of 88. The average improvement of HV angle was from 37.9° to 10.0°. The intermetatarsal angle improved from 16.0° to 8.0°. The average first metatarsal shortening was 0.3 mm. Neither delayed union nor osteonecrosis was observed.ConclusionScarf osteotomy is a reliable procedure to achieve correction of HV deformity with good patient satisfaction.

中 文 摘 要Scarf 截骨術是一個技術要求很高的程序，早期報告顯示，有較高的並發症。 但是，這截骨術可允許橫向平移和角度矯正拇外翻畸形。本研究的目的是評估在我院進行的 scarf 截骨術的臨床和影像學結果。我們回顧了25例患者31足，平均隨訪16個月（範圍6-30個月）。在最新的隨訪，77％的患者滿意的結果，平均手術後的美國骨科足與踝關節協會得分(AOFAS)為88。拇外翻角平均由37.9° ‬改善為10.0°。蹠骨間角從16.0°改善到8.0°。第一蹠骨改善平均縮短了0.3毫米。無延遲癒合或骨壞死。我們的結論是，Scarf 截骨術是一種可靠的方法，使拇外翻畸形矯正，而且病者滿意
