The purpose of this study was to evaluate the outcome of patients who underwent glenoid bone grafting and implantation of a reverse design prosthesis in 1 or 2 stages for the treatment of glenoid bone loss and rotator cuff insufficiency. Indications for the reverse prosthesis in this series included cuff tear arthropathy and revision arthroplasty. Nine patients were reviewed clinically and radiographically with a minimum 2-year follow-up (range, 24-41 months). Despite a low postoperative functional score (mean Constant score, 53 points [range, 22-79 points]), most patients were satisfied with their results primarily because of pain relief. (The mean pain score increased from 3 points preoperatively to 12.5 points postoperatively.) Radiographic evaluation did not demonstrate component loosening or evidence of graft failure. Six patients had radiographic evidence of an inferior scapular notch, which may be of concern in the future. Early results of this procedure are encouraging, but further clinical and radiologic assessment is necessary.

:本研究的目的是评估接受关节盂骨移植并在1或2个阶段植入反向设计假体以治疗关节盂骨丢失和肩袖功能不全的患者的预后。本系列反向假体的适应症包括袖套撕裂性关节炎和翻修置换术。对9例患者进行了临床和影像学检查,至少随访2年(范围24-41个月)。尽管术后功能评分较低(平均恒定评分为53分[范围,22-79分]),但大多数患者对他们的结果感到满意的主要原因是疼痛减轻。 (平均疼痛评分从术前的3分增加到术后的12.5分。)影像学评估未显示组件松动或移植失败的迹象。六例患者的放射学证据显示肩s骨下凹,将来可能会引起关注。该方法的早期结果令人鼓舞,但需要进一步的临床和放射学评估。
