桡管的解剖学研究

本文用解剖剥离和放大的方法,对50侧(25具成人尸体)骨间后神经和桡管进行观察,详细描述了桡管的组成、长度和内容,发现旋后肌腱弓的出现率为32％,桡侧腕短伸肌腱弓的出现率为78％,两种腱弓直接紧邻骨间后神经,认为这种解剖结构可能是桡管综合征发病学的因素之一。

A STUDY ON THE ANATOMY OF THE RADIAL TUNNEL

In order to seek the anatomical factor in paralysis of the posterior interos-seous nerve, this paper reports 50 specimens, including the formation, length and contents of radial tunnel with emphasis on the relationship of posterior intero-sseous nerve and its branches with the radial tunnel syndrome.In our observation, the bifurcations of the terminal branches of radial nerves are all in the middle segments of radial tunnel. The tendinous arch (Frohse arch) of supinator muscles appears in 30% of the cases, The tendious arch of the extensor carpi radialis brevis muscle appears in 78%. Both arches are close to the posterior interosseous nerve. Reveiwing some reports of operation of radial tunnel syndrome, we consider that the radial tunnel syndrome may be caused by an anatomical factor in pathological base.
