目前尚不清楚第一排过长是否是拇外翻复发的危险因素。本研究的目的是为了阐明第一条射线过长与拇外翻复发的关系。回顾性分析了2008年至2011年期间在我们的足踝中心接受chevron截骨联合远端软组织手术的186只足（左侧105只，右侧81只）。术后拇外翻角（HVA）≥20°定义为复发。将患者分为复发组和未复发组。在术前和末次随访时评价两组的负重X线片。X线片测量拇趾长（P1）、第二趾长（P2）、第一、第二跖骨间距离（D）、外翻角（HVA）。利用EL = P_1-P_2-D公式计算了第一射线的余长（EL）。末次随访时，共有45例患者（24.2%）出现拇外翻复发，平均随访时间为83.7 ±12.1个月（范围：66-110）。复发组术后P1平均值为5.06±0.39cm，无复发组为4.84±0.34cm（P<0.001）。复发组和无复发组的平均术后EL分别为5.71±5.01mm和1.61±4.09mm（p<0.001）。术后P1和术后EL对拇外翻复发的预测临界值分别为4.9 cm [比值比（OR）= 8.67，p = 0.03]和0.4 cm（OR = 6.79，p = 0.001）。根据我们的放射学结果，确定了术后P1、术后EL和拇外翻复发之间的显着关系。术后P1>4.9cm和术后EL>0.4cm可能是拇外翻复发的危险因素。术前对第一条射线过长的认识可能有助于改善手术效果。
It is still unknown whether the excessive length of the first ray is a risk factor for hallux valgus recurrence. The purpose of this study is to clarify the relationship between the excessive length of the first ray and the recurrence of hallux valgus. Between 2008 and 2011, a total of 186 feet (left 105, right 81) who underwent chevron osteotomy combined with distal soft tissue procedure in our foot and ankle center were retrospectively reviewed. A postoperative hallux valgus angle(HVA) ≥20° was defined as recurrence. Patients were divided into two groups: recurrence and non-recurrence group. Weight-bearing radiographs were evaluated preoperatively and at the time of last follow-up for both groups. Radiographic parameters including the length of the great toe(P1), the length of the second toe(P2), the length distance between the first and second metatarsal(D), the hallux valgus angle(HVA) were obtained. The excessive length of the first ray(EL) was calculated using the equation of EL = P1-P2-D. A total of 45 patients (24.2%) had hallux valgus recurrence at the time of last follow-up with a mean follow-up of 83.7 ±12.1 months (range, 66–110). The mean postoperative P1 was 5.06±0.39cm for recurrence group and 4.84±0.34cm for no recurrence group(p<0.001). The mean post operative EL was 5.71±5.01mm for recurrence group and 1.61±4.09mm for no recurrence group(p<0.001). The predictive cutoff value of postoperative P1 and postoperative EL for hallux valgus recurrence was 4.9cm [odds ratio (OR) = 8.67, p = 0.03] and 0.4cm (OR = 6.79, p = 0.001) respectively. Significant relationships between postoperative P1, postoperative EL and hallux valgus recurrence were identified according to our radiographic results. A postoperative P1>4.9cm and postoperative EL>0.4cm can be risk factors for hallux valgus recurrence. The appreciation of the excessive length of the first ray prior to surgery may help to improve the surgical outcome.
