METHODS: A systematic review of the literature was completed until May 2020 using PubMed, EMBASE, CINAHL and Cochrane databases, according to PRISMA guidelines.
RESULTS: The literature search revealed 2942 studies, of which 13 were included in this review, with a total of 517 patients and a mean follow-up between 6.4 and 101.6 months. The total complication rate was 6.5%, while 3.3% were humeral associated complications. Finally, the rate of shoulders that underwent a reintervention was 6.7%, with 1.4% relating to a humeral component reason. Stemless RSA led to substantial improvements in patient reported outcome measures and range of motion across all studies. Scapular notching was reported in 15.2%, and lucencies around humeral component were reported in 0.8% of shoulders.
CONCLUSIONS: Stemless RSA resulted in low complication and reintervention rates at the mid-term follow-up. The reported clinical and radiological outcomes showed that these prostheses have at least equivalent outcomes with their stemmed counterparts. Further studies are required to investigate the long-term longevity and performance of the stemless humeral implants.
METHODS: Level IV; Systematic Review.
方法:使用PubMed完成了对文献的系统回顾,直到2020年5月,EMBASE,CINAHL和Cochrane数据库,根据PRISMA指南。
结果:文献检索显示2942项研究,其中13项包括在本次审查中,共517例患者,平均随访6.4至101.6个月。总并发症发生率为6.5%,3.3%为肱骨相关并发症。最后,接受再干预的肩膀率为6.7%,1.4%与肱骨部件有关。无茎RSA导致所有研究中患者报告的结果指标和运动范围的实质性改善。据报道,肩胛骨缺口占15.2%,据报道,肱骨周围的透明度占肩关节的0.8%。
结论:无茎RSA导致中期随访时并发症和再干预率低。报告的临床和放射学结果表明,这些假体与茎状假体至少具有相同的结果。需要进一步的研究来研究无茎肱骨植入物的长期寿命和性能。
方法:IV级;系统评价。
