A retrospective study was performed for Austin (Chevron) and basilar type osteotomies of the first metatarsal in patients with preoperative intermetatarsal angles in the range of 13 to 16 degrees. Results indicated better radiographic correction for both groups than in previous studies. When comparing the results for the Chevron and basilar groups, the radiographic results were almost identical, but the Chevron group appeared to have a slightly better subjective result with less complications of metatarsalgia and callus formation and a better range of motion. Comparing intermetatarsal angle correction as a function of the preoperative hallux adductus, no definitive conclusions were made. However, the trend appears to have reduced correction with higher hallux abductus angles.
对术前跖间角在13至16度范围内的患者进行了关于第一跖骨的奥斯汀（人字形）截骨术和基底型截骨术的回顾性研究。结果表明，两组的影像学矫正效果均优于以往研究。比较人字形组和基底型组的结果时，影像学结果几乎相同，但人字形组的主观结果似乎略好，跖痛症和胼胝形成的并发症较少，活动范围也更好。比较作为术前拇趾内收功能的跖间角矫正情况，未得出明确结论。然而，趋势似乎是拇趾外展角度越高，矫正程度越低。
