Pathology involving the long head of the biceps tendon is a common source of shoulder pain. Biceps tenodesis has been successfully used in areas below the pectoralis, above the pectoralis, and above the biceps groove. However, clinical data are lacking for additional techniques for tenodesis at the superior aspect of the biceps groove.
A biomechanical comparison was completed examining six matched pairs of cadaveric shoulders. The ultimate load to failure was compared between an inlay and onlay biceps tenodesis at the superior aspect of the biceps groove.
The results demonstrate an average construct strength of 215 N for the inlay technique and 210 N for the onlay technique. The difference between the two techniques was not significant.
This study demonstrates similar biomechanical strength for both constructs.
肱二头肌长头腱相关病理改变是肩部疼痛的常见原因。肱二头肌固定术已成功应用于胸大肌下方、胸大肌上方及肱二头肌沟上方区域。然而，关于肱二头肌沟上方区域进行固定术的其他技术，临床数据尚缺乏。
完成了一项生物力学比较研究，对六对匹配的尸体肩部进行检测。比较了肱二头肌沟上方区域镶嵌式和覆盖式肱二头肌固定术的极限破坏载荷。
结果表明，镶嵌式技术的平均结构强度为215 N，覆盖式技术为210 N。两种技术之间的差异不显著。
本研究表明两种结构具有相似的生物力学强度。
