解剖观测了100例成人的肌皮神经、胸背神经和下肩胛下神经。对20例肌皮神经进行了神经干内分离研究,绘制了10个部位的神经干内局部定位示意图。 建议选用胸背神经或下肩胛下神经移位,远端尽可能低位与肌皮神经各肌支吻合的新手术设计方案,用以治疗臂丛高位严重损伤所造成的屈肘功能丧失。 A total of 100 adult musculocutaneous nerves, thoracic dorsal nerve, and inferior subscapular nerve were observed. 20 cases of musculocutaneous nerve were subjected to neural stem internal separation study, and 10 parts of the local map of nerve trunk were drawn. Proposed selection of thoracodorsal or subscapular nerve transposition, distal as low as possible and musculocutaneous nerve muscular branch of the new surgical design, for the treatment of severe brachial plexus injury caused by loss of elbow flexion.
