拇长伸肌副腱是一种常见的解剖变异，其临床意义尚存在争议。本研究的目的是调查的发病率和形态的副EHL肌腱尸体，并检查任何可能的相关性的发生和严重程度的拇外翻（HV）畸形。我们研究了任何可能的相关性之间的AT的存在和尸体的年龄和HV畸形在98个女性成人尸体足。测量HV和跖骨间（IMA）角，并与原始EHL肌腱与AT之间的相对角度以及AT的长度进行比较。AT的存在率为26.5%，HV畸形的存在率为36.7%。AT足HV畸形的发生率较高（65.4%），但AT足和无AT足的HV角和IMA相似。AT形态特征与尸体年龄、HV角、IMA无明显相关性。结论：EHL中AT的尸体足HV畸形发生率高（约2/3），但HV畸形的严重程度与AT的存在或特征无关。
The accessory tendon (AT) of the extensor hallucis longus (EHL) is a common anatomic variation, whose clinical significance remains debatable. The purpose of this study was to investigate the incidence and morphology of accessory EHL tendons in cadavers and to examine any possible correlation to the occurrence and severity of hallux valgus (HV) deformity.We examined any possible correlation between the AT presence and the cadavers' age and the HV deformity in 98 female adult cadaveric feet. The HV and intermetatarsal (IMA) angles were measured and compared with the relative angle between the primary EHL tendon and AT as well as the length of the AT.AT was present in 26.5% and HV deformity existed in 36.7% of all feet. There was a high prevalence (65.4%) of HV deformity in feet with AT, but the HV angle and IMA were similar in feet with AT and without AT. No significant correlations were found between AT morphological characteristics and the cadavers' age or the HV angle and IMA.In conclusion, there is a high incidence of HV deformity in cadaveric feet with AT of EHL (almost 2/3), but there is no correlation between the severity of the HV deformity and the presence or characteristics of the AT.
