Abstract：
UNASSIGNED: The use of stemless total shoulder arthroplasty (TSA) for osteoarthritis increases, but there is a paucity on its safety and efficacy and how it performs in comparison with stemmed TSA. The aim was to compare the 5-year cumulative survival rate and patient-reported outcome after stemless and stemmed TSA for osteoarthritis.
UNASSIGNED: We included all stemmed (n = 1197) and stemless (n = 253) TSA for osteoarthritis reported to the Danish shoulder arthroplasty registry from January 1, 2014, to December 31, 2018.
UNASSIGNED: Six (2.4%) stemless and 24 (2%) stemmed TSA were revised. The 5-year cumulative implant survival rates were 0.96 for stemless TSA and 0.97 for stemmed TSA. In the multivariate Cox regression model, the hazard ratio for revision was 1.1 (95% confidence interval, 0.5-2.6) for stemless TSA compared with stemmed TSA. The mean Western Ontario Osteoarthritis of the Shoulder (WOOS) index was 82 (standard deviation = 21) for stemmed and 86 (standard deviation = 19) for stemless TSA. The stemless TSA had a statistically significant better WOOS compared with stemmed TSA, but the difference of 6.2 (95% confidence interval, 1.4-10.4) was not regarded as clinically relevant. There was no difference in WOOS between the Nano and the Eclipse systems.
UNASSIGNED: We found a good 5-year cumulative implant survival rate of stemless TSA, which was comparable with stemmed TSA. Although the stemless TSA had a statistically significant better patient-reported outcome compared with stemmed TSA, the difference was not clinically relevant. Sparing the humeral shaft canal for later revision could be an argument for using stemless TSA instead of stemmed TSA.

摘要：
未经授权：无柄全肩关节置换术（TSA）用于骨关节炎的增加，但缺乏其安全性和有效性以及与茎状TSA相比的性能。目的是比较无茎和有茎的TSA治疗骨关节炎后的5年累积生存率和患者报告的结果。
UNASSIGNED：我们纳入了2014年1月1日至2018年12月31日在丹麦肩关节成形术登记处报告的所有有茎的(n=1197)和无茎的(n=253)TSA。
未经评估：修订了6个（2.4%）无茎TSA和24个（2%）无茎TSA。无茎TSA和有茎TSA的5年累积植入物存活率分别为0.96和0.97。在多元Cox回归模型中，修订的风险比为1.1(95%置信区间，0.5-2.6）与无茎TSA相比。有茎TSA的西部安大略省肩关节关节炎（WOOS）指数平均为82（标准偏差=21），无茎TSA为86（标准偏差=19）。无茎TSA与有茎TSA相比，具有统计学上显着的更好的WOOS，但相差6.2(95%置信区间，1.4-10.4）不被认为是临床相关的。Nano和Eclipse系统之间的WOOS没有区别。
UNASSIGNED：我们发现无茎TSA的5年累积植入物存活率良好，与茎状TSA相当。尽管无茎TSA与有茎TSA相比，患者报告的结果在统计学上显着更好，差异无临床意义.保留肱骨轴管以供以后翻修可能是使用无茎TSA代替有茎TSA的论点。
