Abstract：
UNASSIGNED: Subscapularis repair has recently garnered significant interest. A thorough understanding of the tendon\'s anatomy is essential for precise and safe repair. Our objectives were to describe the anatomy of the subscapularis insertion, define its landmarks, and analyze nearby structures to guide arthroscopic repair.
UNASSIGNED: We conducted an anatomical study, dissecting 12 shoulders. We evaluated the distance from the footprint to the axillary nerve, the dimensions, and shape of the footprint, and its relationship with the humeral cartilage.
UNASSIGNED: The distance to the axillary nerve was 32 mm (standard deviation [SD], 3.7 mm). The craniocaudal length of the footprint was 37.3 mm (SD, 4.6 mm). Its largest mediolateral thickness was 16 mm (SD, 2.2 mm), wider at the top and narrower distally. The distance between the footprint and the cartilage varied, being 3.2 mm (SD, 1.2 mm) in the upper part, 5.4 mm (SD, 1.8 mm) in the medium, and 15.9 mm (SD, 2.9 mm) in the lower part.
UNASSIGNED: When performing a repair of the subscapularis tendon, the distance to the cartilage should be carefully evaluated as it varies proximally to distally, and the shape of the footprint (wider proximally, tapered distally) should be considered for implant positioning. The distance to the axillary nerve is approximately 30 mm. Anterior visualization guarantees direct control of all landmarks and allows accurate implant positioning with safe tendon release.

摘要：
■肩胛骨下修复最近引起了极大的兴趣。彻底了解肌腱的解剖结构对于精确和安全的修复至关重要。我们的目标是描述肩胛骨下插入的解剖结构，定义它的地标，并分析附近的结构以指导关节镜修复。
■我们进行了一项解剖学研究，解剖12个肩膀。我们评估了从脚印到腋下神经的距离，尺寸，和足迹的形状，以及它与肱骨软骨的关系。
■到腋下神经的距离为32mm（标准偏差[SD]，3.7mm)。足印的颅尾长度为37.3毫米(SD，4.6mm)。其最大中外侧厚度为16mm（SD，2.2mm),顶部较宽，远端较窄。脚印和软骨之间的距离各不相同，为3.2毫米(SD，1.2mm)在上部,5.4mm(SD,1.8毫米)在介质中，和15.9毫米(SD，2.9毫米)在下部。
■进行肩胛骨下肌腱修复时，到软骨的距离应该仔细评估，因为它在近端到远端变化，和脚印的形状(近侧更宽，远端锥形）应考虑用于植入物定位。到腋下神经的距离约为30mm。前可视化保证直接控制所有标志，并允许准确的植入物定位与安全的肌腱释放。
