摘　　要：目的研究肌肉再分布技术中关键肌肉-肌腱运动单元的外科腱腹交界部位,为不同平面截肢病例选择合理的肌肉再分布手术方案提供解剖学依据。方法取新鲜上肢标本6侧,对前臂关键肌肉-肌腱运动单元,包括拇长屈肌、示指指深屈肌、肱梯肌、桡侧腕屈肌、拇长伸肌、示指固有伸肌、桡侧腕长伸肌、尺侧腕伸肌,分别测量其外科腱腹交界部位距肱骨内上髁的距离。结果拇长屈肌、示指指深屈肌、肱桡肌、桡侧腕屈肌、拇长伸肌、示指固有伸肌、桡侧腕长伸肌、尺侧腕伸肌的外科腱腹交界部位距离肱骨内上髁的平均距离分别为(21.83±0.68)cm、(21.92±0.73)cm,(15.08±0.86)cm、(12.58±0.58)cm、(22.33±0.41)cm,(24.58±0.58)cm,(9.17±0.93)cm、(17.58±0.58)cm。结论上述解剖学研究结果证实不同平面的前臂截肢患者可以采用两套方案进行肌肉再分布手术,通过浅置控制拇指和示指运动的位于前臂深面的肌肉运动信号,将有助于智能仿生手识别重要的人体运动意图。Objective To investigate the position of the major muscle-tendon motor units for muscle redistribution technique(MRT),so as to provide anatomic basis for selecting reasonable muscle redistribution operation plan for amputation cases at different levels.Methods Six fresh upper limb specimens were collected.The flexor pollicis longus,the flexor digitorum profundus of index finger,the brachioradialis,the flexor carpi radialis,the extensor pollicis longus,the extensor indicis propria,the extensor carpi radialis longus,and the extensor carpi ulnaris were investigated as the major muscle-tendon motor units in forearms.The distance from the surgical musculotendinous junction of each motor unit to the medial epicondyle of the humerus was measured.Results Respectively,the average distance from the musculotendinous junctions to the medial epicondyle of humerus for the flexor pollicis longus,the flexor digitorum profundus of index finger,the brachioradialis,the flexor carpi radialis,the extensor pollicis longus,the extensor indicis propria,the extensor carpi radialis longus,and the extensor carpi ulnaris were(21.83±0.68)cm,(21.92±0.73)cm,(15.08±0.86)cm,(12.58±0.58)cm,(22.33±0.41)cm,(24.58±0.58)cm,(9.17±0.93)cm,and(17.58±0.58)cm.Conclusion It is confirmed that the patients with different levels of forearm amputation can adopt two sets of muscle redistribution surgery.It will be helpful for the intelligent bionic hand to recognize the important human movement intention by shallowly placing the muscle movement signals in the deep forearm to control the movement of thumb and index finger.
