The chevron osteotomy is a widely used procedure in the surgical treatment of symptomatic mild to moderate hallux valgus deformity. Biplanar chevron osteotomy has previously been described to correct the deformity in two planes. There are patients in whom the ideal procedure would include lateral translation of the head (to correct the hallux valgus and intermetatarsal angles), angular correction of the abnormal lateral inclination of the joint surface and, finally, plantar displacement of the head fragment without significantly shortening the first ray as might the Youngswick-Austin procedure.
This paper describes a variation of the chevron osteotomy.
We believe that this osteotomy achieves correction of the hallux valgus deformity in three planes.
V形截骨术是治疗有症状的轻度至中度拇外翻畸形的外科手术中广泛使用的一种术式。双平面V形截骨术此前已被描述用于在两个平面上矫正畸形。有些患者理想的手术应包括将拇趾头部向外侧移位（以矫正拇外翻和跖间角）、矫正关节面异常的外侧倾斜角度，最后，使头部骨块向足底移位，而不像扬斯威克-奥斯汀术式那样显著缩短第一跖骨。
本文描述了一种V形截骨术的变体。
我们认为这种截骨术可在三个平面上矫正拇外翻畸形。
