The subscapularis muscle, which is part of the rotator cuff, is located anterior to the shoulder. In anterior approaches to the shoulder, its supplying nerves are at risk of iatrogenic injury, which may cause postoperative complications. It is unclear whether there is any nerve-free zone in which a subscapularis split can be performed without risking nerve damage.

是否存在可以安全进行肩胛下肌劈裂的无神经区？使用防腐标本的解剖学研究。

肩胛下肌是肩袖的一部分，位于肩部前方。在肩部前路手术中，其供应神经面临医源性损伤的风险，这可能会导致术后并发症。目前尚不清楚是否存在任何无神经区域，可以在其中进行肩胛下肌劈开而不会有神经损伤的风险。
