Total shoulder arthroplasty (TSA) with a nonspherical humeral head component and inlay glenoid is a bone preserving treatment for glenohumeral arthritis. This study aims to describe minimum two year patient reported outcomes, patient acceptable symptomatic state (PASS) achievement, and complications following TSA with this prosthesis.
A retrospective review of patients undergoing TSA with nonspherical humeral head and inlay glenoid was performed. Outcomes included Single Assessment Numeric Evaluation (SANE) scores, American Shoulder and Elbow Surgeons (ASES) scores, and complications. SANE and ASES scores were compared to established PASS threshold values to determine PASS achievement.
56 TSA in 53 patients were identified. The mean age was 64.5 years, 64% were male, and mean follow-up was 29.2 ± 4.9 months (24.0-42.8). Two complications (3.6%) were observed: one subscapularis tear requiring revision to reverse TSA and one traumatic minimally displaced greater tuberosity fracture successfully treated nonoperatively. The mean SANE score was 84.3 ± 16.9 (40-100) and 77% of patients surpassed the PASS threshold of 75.5. The mean ASES score was 85.3 ± 15.7 (40-100) and 77% of patients surpassed the PASS threshold of 76.
Patients undergoing TSA with a nonspherical humeral head and inlay glenoid demonstrated high PASS achievement rates and few complications at short-term follow-up.
采用非球形肱骨头部件和镶嵌式关节盂的全肩关节置换术（TSA）是一种治疗盂肱关节炎的保骨治疗方法。本研究旨在描述采用这种假体进行TSA术后至少两年的患者报告结局、患者可接受症状状态（PASS）达成情况及并发症。
对接受非球形肱骨头和镶嵌式关节盂TSA的患者进行回顾性研究。结局指标包括单项评估数字评定（SANE）评分、美国肩肘外科医师（ASES）评分及并发症。将SANE和ASES评分与既定的PASS阈值进行比较，以确定PASS达成情况。
共纳入53例患者的56例TSA。平均年龄64.5岁，64%为男性，平均随访时间为29.2±4.9个月（24.0 - 42.8个月）。观察到2例并发症（3.6%）：1例肩胛下肌撕裂，需翻修以逆转TSA；1例创伤性轻度移位的大结节骨折，非手术治疗成功。平均SANE评分为84.3±16.9（40 - 100），77%的患者超过了75.5的PASS阈值。平均ASES评分为85.3±15.7（40 - 100），77%的患者超过了76的PASS阈值。
接受非球形肱骨头和镶嵌式关节盂TSA的患者在短期随访中显示出较高的PASS达成率且并发症较少。
