The course of the suprascapular nerve and its distance from fixed scapular landmarks were measured in 90 cadaveric shoulders. In an additional 15 cadavers, three pins were passed at various angles in a general anterior-posterior direction through the middle of the glenoid neck just inferior and lateral to the base of the coracoid process. The distance between the exit site on the posterior glenoid neck and the suprascapular nerve at the base of the scapular spine was recorded for each pin. Inferiorly directed pins were the furthest from the suprascapular nerve and averaged 16 mm. On the basis of these data, a relative safe zone is described in the posterior glenoid neck. Knowledge of the anatomic course of the suprascapular nerve may aid the physician in the diagnosis and treatment of suprascapular neuropathies. Appreciation of the safe zone may help the shoulder surgeon avoid iatrogenic injury to the suprascapular nerve during arthroscopic Bankart procedures and other open surgical procedures requiring dissection of the posterior glenoid neck.
在90具尸体肩部测量了肩胛上神经的走行及其与肩胛骨固定标志的距离。在另外15具尸体中,沿大致前后方向以不同角度将三根钢针穿过肩胛盂颈中部,恰好在喙突基部的下方和外侧。记录每根钢针在肩胛盂后颈部的穿出点与肩胛冈基部的肩胛上神经之间的距离。向下的钢针离肩胛上神经最远,平均距离为16毫米。基于这些数据,描述了肩胛盂后颈部的一个相对安全区。了解肩胛上神经的解剖走行可能有助于医生诊断和治疗肩胛上神经病变。认识这个安全区可能有助于肩部外科医生在关节镜下Bankart手术及其他需要解剖肩胛盂后颈部的开放手术中避免医源性肩胛上神经损伤。
