【摘要】 目的观察■长伸肌副腱的解剖学特征,并分析该副腱与■外翻畸形的相关性。方法 90例(左、右各45例)经10%福尔马林溶液灌注固定的人体下肢标本,解剖踇长伸肌及其副腱;采用游标卡尺及量角器,测量副腱的长度、宽度、副腱角及其止点宽度,测量■外翻角;分析上述测量结果与外翻畸形的相关性。结果 (1)86例标本具有■长伸肌副腱,45例标本出现外翻畸形;(2)■长伸肌副腱的数量如下:1支80例、2支5例;与■短伸肌腱共同止点变异1例;(3)■外翻组副腱的长度、宽度、副腱角及止点宽度分别是(85.02±22.27)mm、(1.84±1.64)mm、(7.83±3.28)°及(9.08±2.71)mm;正常组副腱的长度、宽度、副腱角及止点宽度分别是(97.51±30.99)mm、(1.62±0.49)mm、(5.99±3.95)°及(9.09±3.09)mm。与正常组相比,■外翻组副腱角明显增加(P=0.04,t=-2.097)。在所有标本中,副腱角与■外翻角呈正相关(P=0.007,r=0.317)。结论人■长伸肌副腱的出现,与■外翻具有一定相关性,却不是导致■外翻畸形的重要原因。对■长伸肌及其副腱的观察,是对既往研究的补充,也为副腱的临床应用提供理论依据。更多还原

【Abstract】 Objective To evaluate the correlation between the hallux valgus and the accessory tendon of the extensor hallucis longus muscle in human cadavers. Methods 90 lower limbs(45 of each side)were perfused with 10%formalin solution. The insertions of the extensor hallucis longus muscle and its accessory tendon were dissected accurately in order to gain the different types. The frequency of occurrence of hallux valgus with each type of insertion was also recorded.Results ① The accessory tendon of the extensor hallucis longus muscle was observed in 86 cases,and 45 cases displayed the deformity of hallux valgus;②The number of accessory tendon of extensor hallucis longus muscle was as follows:1 in 80 cases;2 in 5 cases;variation with the extensor hallucis brevis in 1 case. ③The length,width,accessory tendon angle and width of the insertion of the accessory tendon were(85.02±22.27)mm,(1.84±1.64)mm,(7.83±3.28)°,(9.08±2.71)mm in the hallux valgus group,respectively,and(97.51±30.99)mm,(1.62±0.49)mm,(5.99±3.95)°,(9.09±3.09)mm in normal groups,respectively,there was statistical significance in the accessroy tendon angle between the normal and the hallux valgus groups(P=0.04,t=-2.097). Conclusion There is a high incidence of hallux valgus deformity in cadaveric feet with accessory tendon of extensor hallucis longus. However,there is little correlation between the severity of hallux valgus and the presence of the accessory tendon.更多还原
