目的进行前臂骨间后神经终末支解剖学研究,为前臂背侧神经肌肉损伤的治疗提供依据。方法解剖40侧成人上肢尸体标本,测量骨间后神经自分支起点至旋后肌远侧缘之间的距离,并记录其分布于各个肌肉的分支长度和数量。结果前臂骨间后神经穿出旋后肌后分出较多短分支和一支较深的长分支。结论熟悉前臂骨间后神经终末支的解剖学特点将有助于指导前臂背侧神经肌肉损伤的治疗。
Objective To study the anatomy of the posterolateral posterior interosseous nerve and provide basis for the treatment of neuromuscular damage on the dorsal forearm. Methods 40 adult adult corpse specimens were dissected and the distance between the origin of the posterior interosseous nerve and the distal edge of the posterior tibialis was measured. The length and number of branches distributed in each muscle were recorded. Results Forearm after the interosseous nerve piercing the posterior spinous muscle branch out more short branches and a deeper long branch. Conclusion The familiar anatomic features of the posterior interosseous posterior branch of the posterolateral nerve will help guide the treatment of neuromuscular damage in the dorsal forearm.
