This is a retrospective study of the chevron osteotomy for hallux valgus. Subjective and objective postoperative results were evaluated. Differences in the postoperative correction of the intermetatarsal 1-2 angle and the first metatarsophalangeal angle were noted using two accepted measurement methods. Seventeen patients (23 feet) with an average age of 39 years (range, 15-51 years) and an average follow-up of 3 years (range, 1-5 years) were studied. The average preoperative intermetatarsal 1-2 angle was 11 degrees (range, 8 degrees to 14 degrees), and the average hallux valgus angle was 23 degrees (range, 7 degrees to 39 degrees). The apparent postoperative correction differed depending on the method of measurement used. One method consistently indicated a greater amount of correction in both the intermetatarsal and metatarsophalangeal angles. The chevron procedure resulted in an overall satisfactory improvement of symptoms, function, and cosmesis. Four feet exhibited postoperative radiographic changes that could be construed as avascular changes, but there was no collapse noted, nor were there clinical symptoms of avascular necrosis. No nonunions, malunions, or infections developed, and no cases of hallux varus occurred.
这是一项关于拇外翻V形截骨术的回顾性研究。对术后主观和客观结果进行了评估。使用两种公认的测量方法记录了第1-2跖骨间角和第一跖趾关节角术后矫正的差异。研究了17例患者（23足），平均年龄39岁（范围15-51岁），平均随访3年（范围1-5年）。术前第1-2跖骨间角平均为11度（范围8度至14度），拇外翻角平均为23度（范围7度至39度）。术后明显的矫正情况因所使用的测量方法而异。一种方法始终显示在跖骨间角和跖趾关节角的矫正量更大。V形手术在症状、功能和美观方面总体改善令人满意。4足术后出现可解释为缺血性改变的影像学变化，但未观察到塌陷，也没有缺血性坏死的临床症状。未发生骨不连、畸形愈合或感染，也未出现拇内翻病例。
