The purpose of this study was to investigate how lateralization shoulder angle (LSA) and distalization shoulder angle (DSA) are related to clinical and kinematic outcomes after reverse total shoulder arthroplasty. Thirty-three patients were evaluated at least six months postoperatively. The Single Assessment Numeric Evaluation (SANE), Constant Murley Score (CMS), Simple Shoulder Test (SST), and Visual Analogue Scale (VAS) were used. Shoulder kinematics was evaluated with a stereophotogrammetric system. LSA and DSA inter-rater reliability was analysed through the interclass correlation coefficient (ICC). Stepwise forward linear regression analysis was conducted between LSA and DSA with clinical scales and kinematic measures, between which a correlation analysis was conducted. The inter-rater reliability for LSA (mean ICC = 0.93) and DSA (mean ICC = 0.97) results were good to excellent. Greater LSA values were associated with higher peaks of internal rotation ( = 0.012, R = 0.188) and range of motion (ROM) ( = 0.037, R = 0.133). SANE ( = 0.009), CMS ( = 0.031), and SST (0.026) were positively correlated to external rotation, while VAS ( = 0.020) was negatively related. Abduction peaks were positively related to CMS ( = 0.011) and SANE ( = 0.037), as well as abduction ROM (SANE, = 0.031; CMS, = 0.014).
本研究的目的是调查在反式全肩关节置换术后，外展肩角（LSA）和内收肩角（DSA）如何与临床和运动学结果相关。对33例患者进行了术后至少6个月的评估。使用了单项评估数字评定法（SANE）、Constant Murley评分（CMS）、简易肩关节测试（SST）和视觉模拟量表（VAS）。采用立体摄影测量系统评估肩部运动学。通过组内相关系数（ICC）分析LSA和DSA的评分者间信度。对LSA和DSA与临床量表及运动学测量值进行逐步向前线性回归分析，并在两者之间进行相关性分析。LSA（平均ICC = 0.93）和DSA（平均ICC = 0.97）的评分者间信度结果为良好至优秀。较高的LSA值与更高的内旋峰值（P = 0.012，R = 0.188）和运动范围（ROM）（P = 0.037，R = 0.133）相关。SANE（P = 0.009）、CMS（P = 0.031）和SST（P = 0.026）与外旋呈正相关，而VAS（P = 0.020）呈负相关。外展峰值与CMS（P = 0.011）和SANE（P = 0.037）以及外展ROM呈正相关（SANE，P = 0.031；CMS，P = 0.014）。
