【摘要】 目的 探讨臂丛颈5、6根性撕脱伤后桡神经尺侧腕伸肌支部分束移位修复旋后肌支解剖上的可行性。 方法 成年上肢标本12具，以肱骨内外上髁连线与桡神经主干的交点(O点)为标记点，沿着桡神经的走行方向，用游标卡尺测量其旋后肌支自然发出点、无损伤分离后发出点、旋后肌支入肌点和尺侧腕伸肌最近端肌支入肌点距O点的距离，并计数两者分支数。 结果 桡神经旋后肌支数为2.6±0.52，其自然分支处距O点(1.84±0.69)cm，干支分离后分支距O点(0.05±0.12)cm，入肌点距O点(4.35±0.12)cm。尺侧腕伸肌支数为2.71±0.73，最近端肌支入肌点距O点(7.18±0.64)cm。 结论 旋后肌支无损伤干支分离后，能与尺侧腕伸肌支直接缝合。

    【Abstract】 Objective To improve possibility of transfer extensor carpi ulnaris branch(ECUB)to supinator branch(SB)in anatomy.Methods Twelve adult embalmed cadaver arms were dissected.We called the point that the radial nerve crossed the line between medial humeral epicondyle and lateral humeral epicondyle as O point.Then we performed the following measurement:the distance from the origin point ......
