This study reviews the outcomes of reverse shoulder arthroplasty (RSA) and introduces a novel method of measuring changes in the center-of-rotation (COR) of the shoulder joint post-operatively.
We performed 10 reverse shoulders in 2011. Patients were evaluated pre-operatively and post-operatively using the Constant Score. The COR of the shoulder was determined pre- and post-operatively on radiographs and the differences were analysed.
There was significant improvement in Constant Scores post-operatively with reduction in pain and increase in strength. Medialisation but not distalisation of the COR was achieved.
Longer follow-up studies and studies on survivalship are required.
本研究回顾了反式肩关节置换术(RSA)的结果,并介绍了一种测量肩关节术后旋转中心(COR)变化的新方法。
2011年我们实施了10例反式肩关节置换手术。术前和术后使用Constant评分对患者进行评估。通过X线片确定术前和术后肩关节的旋转中心,并分析其差异。
术后Constant评分显著改善,疼痛减轻,力量增加。实现了旋转中心的内移而非下移。
需要进行更长时间的随访研究和生存率研究。
