The authors have shown the chevron osteotomy to be an effective operation for hallux valgus where degenerative changes have not occurred in the metatarsophalangeal joint. Chevron osteotomy is normally restricted to younger patients, yet in this study there has been no upper limit for age and the authors have shown a high rate of patient satisfaction with good mobility and cosmesis. Results are not significantly operator-dependent, and the procedure is simple and reliable. The authors have been unable to verify previous reports in smaller studies of the serious complication of avascular necrosis of the metatarsal head on clinical or radiological grounds.
作者已证明，对于跖趾关节未发生退行性改变的拇外翻患者，V形截骨术是一种有效的手术方法。V形截骨术通常适用于较年轻的患者，但在本研究中，年龄并无上限，作者发现患者满意度较高，关节活动度和美观效果良好。结果并不明显依赖于手术医生，且该手术操作简单、可靠。基于临床和影像学依据，作者无法证实之前较小规模研究中关于跖骨头缺血性坏死这一严重并发症的报道。
