Postoperative insufficiency of the subscapularis can diminish clinical outcome after shoulder arthroplasty. Poor tendon tissue quality and prior surgery can impair the possibility of reconstruction and healing, as well as the postoperative range of motion and strength. Patch augmentation has been investigated for soft tissue augmentation in the glenohumeral joint utilizing different graft materials. Recently, the surgical technique using compressed biceps tendon autograft was introduced for the subscapularis augmentation following shoulder arthroplasty. However, the viable cell potential after mechanical compression remains uncertain. Therefore, we propose an augmentation technique of the subscapularis tendon using a sliced autograft of the long head of the biceps tendon. This technique can offer a simple, replicable, and cost-effective autologous tendon patch augmentation after subscapularis tenotomy in the setting of total shoulder arthroplasty.
肩胛下肌术后功能不全可降低肩关节置换术后的临床疗效。肌腱组织质量差和既往手术会损害重建与愈合的可能性，以及术后的活动范围和力量。人们已经研究了使用不同移植材料进行盂肱关节软组织增强的补片增强术。最近，一种使用自体肱二头肌肌腱压缩移植的手术技术被引入用于肩关节置换术后的肩胛下肌增强。然而，机械压缩后存活细胞的潜力仍不确定。因此，我们提出一种使用肱二头肌长头自体移植切片进行肩胛下肌腱增强的技术。在全肩关节置换术中，该技术可在肩胛下肌切断术后提供一种简单、可重复且经济高效的自体肌腱补片增强方法。
