Abstract：
UNASSIGNED: The medium-term results of reverse shoulder arthroplasty (RSA) that has been performed by a single surgeon have been previously reported. The purpose of this study was to investigate the minimum 10-year clinical and radiographic outcomes of these patients.
UNASSIGNED: In this prospective cohort study, 27 patients were evaluated after RSA for massive rotator cuff tear with or without eccentric osteoarthritis (OA) or concentric OA with the Constant-Murley Score (CMS), range of motion (ROM), and a radiologic assessment.
UNASSIGNED: At a mean 12-year follow-up, the CMS and ROM were significantly improved when compared with the baseline values (all P < .001). Once stratified by diagnosis, no difference in the ROM or total CMS was found between patients with massive rotator cuff tear with/without eccentric OA and those with concentric OA. Neither ROM nor CMS decreased when compared to the mid-term values of the previous study, for both the overall population and the diagnosis-stratified groups. Scapular notching was reported in 66.7% of cases that was similar to the data reported at mid-term follow-up. The calcification rate was 59.3% at the long-term evaluation, and there were no differences between the same case-series population (51.9%; P = .785) and the whole population at mid-term follow-up (47%; P = .358).
UNASSIGNED: RSA led to excellent clinical and functional outcomes for patients up to 17 years postoperatively, and there was no decrease in the CMS over time. No loosening of implants was noted, and the rate of scapular notching was 66%, mostly grade 1 or 2.

摘要：
■以前曾报道过由一名外科医生进行的反向肩关节成形术（RSA）的中期结果。这项研究的目的是调查这些患者的最低10年临床和影像学结果。
■在这项前瞻性队列研究中，采用Constant-Murley评分(CMS)对27例患者进行RSA术后肩袖大面积撕裂伴或不伴偏心性骨关节炎(OA)或同心性OA的评估,运动范围（ROM），和放射学评估。
■在平均12年的随访中，与基线值相比，CMS和ROM显着改善（所有P<.001）。一旦根据诊断进行了分层，在有/无偏心OA的肩袖大面积撕裂患者和有同心OA的患者之间,ROM或总CMS没有差异.与先前研究的中期值相比，ROM和CMS均未降低，对于总体人群和诊断分层组。在66.7％的病例中报告了肩胛骨切口，这与中期随访时报告的数据相似。长期评价钙化率为59.3%,中期随访时,相同病例系列人群(51.9%;P=.785)与整个人群(47%;P=.358)之间无差异.
■RSA导致患者术后长达17年的良好临床和功能结果，随着时间的推移，CMS没有减少。未发现植入物松动,肩胛骨缺口率为66%，主要是1级或2级。
