» Reverse total shoulder arthroplasty was designed to function in the rotator cuff deficient shoulder by adjusting the glenohumeral center of rotation (COR) to maximize deltoid function.» Adjustments in the COR ultimately lead to changes in resting tension of the deltoid and remaining rotator cuff, which can affect implant stability and risk of stress fracture.» Soft-tissue balance and complication profiles can be affected by humeral component (version, neck shaft angle, and inlay vs. onlay) and glenoid component (sagittal placement, version, inclination, and lateralization) design and application.» A good understanding of the effects on soft-tissue balance and complication profile is critical for surgeons to best provide optimal patient outcomes.
» 反式全肩关节置换术旨在通过调整盂肱关节中心旋转（COR）来适应肩袖缺失的肩关节，以最大限度地发挥三角肌的功能。» COR 的调整最终会导致三角肌和剩余肩袖的静息张力发生变化，这可能会影响植入物的稳定性和发生应力性骨折的风险。» 软组织平衡和并发症的发生与肱骨组件（型号、颈干角、镶嵌物与覆盖物）和肩胛盂组件（矢状位置、型号、倾斜度和外侧化）的设计和应用有关。» 外科医生需要充分了解对软组织平衡和并发症的影响，以提供最佳的患者治疗效果。
