INTRODUCTION Latest trends in shoulder replacement aim at bone stock preservation. Long-term results of stemless anatomical total shoulder implants compare favourably with stemmed designs in terms of function and survivorship. The Total Evolutive Shoulder System (TESS) has been one of the first designs offering a stemless implant not only for anatomical but also for reverse total shoulder arthroplasty with optional short stem attachment in cases with poor bone quality. The aim of the present study was to evaluate long-term results of the reverse Total Evolutive Shoulder System (TESS). MATERIALS AND METHODS Between 2006 and 2009, 49 shoulders in 47 patients were replaced using the Biomet reverse Total Evolutive Shoulder System (TESS). 29 shoulders in 27 patients who were aged 72.4 ± 6.7 (53-88) years were available for review at a mean follow-up of 101.6 ± 24.6 (75-142) months. RESULTS The implant survival rate was 93.1% at 101 months (8.4 years). The overall revision rate of the TESS implant was 17.2%. No implant associated complications to the reverse corolla implant could be observed. All reverse corolla implants showed solid fixation at follow-up. Scapular notching was found in 72.3% of the shoulders. Clinical scores significantly improved at long-term follow-up (VAS from 7.5 ± 1.2 to 1.4 ± 1.5, p < 0.001; quick-DASH from 70.9 ± 12.0 to 28.9 ± 22.9, p < 0.001 and Constant score from 13.0 ± 3.7 to 60.5 ± 16.8, p < 0.001). CONCLUSIONS In terms of clinical scores, radiographic loosening, complication rates and implant survivorship the reverse Total Evolutive Shoulder System provides results comparable to those of conventional stemmed reverse shoulder arthroplasty.

反向总进化肩膀系统（TESS）的长期结果。

引言肩关节置换术的最新趋势旨在保护骨质。在功能和存活率方面，无茎解剖型全肩关节植入物的长期结果优于有茎设计。全面进化肩部系统（TESS）是最早提供无茎植入物的设计之一，该植入物不仅用于解剖学，而且还用于反向全肩关节置换术，在骨质量较差的情况下还可以选择短茎附着。本研究的目的是评估反向总进化肩系统（TESS）的长期结果。材料与方法在2006年至2009年之间，使用Biomet反向总进化肩关节系统（TESS）替代了47位患者中的49根肩膀。27位年龄为72.4±6。可以回顾7（53-88）年，平均随访101.6±24.6（75-142）个月。结果101个月（8。4年）的植入物存活率为93.1％。TESS植入物的总体翻修率为17.2％。没有观察到与反向花冠植入物相关的并发症。所有反向花冠植入物在随访中均显示出牢固的固定。72.3％的肩部发现肩cap骨切口。长期随访（VAS从7.5±1.2到1.4±1.5，p <0.001;快速DASH从70.9±12.0到28.9±22.9，p <0.001，恒定评分从13.0±3.7到60.5）的临床评分显着改善±16.8，p <0.001）。结论从临床评分，影像学检查松动，
