We systematically reviewed the literature for studies of currently available canal-sparing respectively stemless shoulder arthroplasty systems. From the identified series, we recorded the indications, outcome measures, and humeral-sided complications.
We identified 11 studies of canal-sparing respectively stemless anatomic shoulder arthroplasty implants, published between 2010 and 2016. These studies included 929 cases, and had a mean follow-up of 26 months (range, 6 to 72 months). The rates of humeral component-related complications ranged between 0 and 7.9 %. The studies reported only a few isolated cases of complications of the humeral component. Some arthroplasty systems are associated with radiological changes, but without any clinical relevance.
All of the published studies of canal-sparing respectively stemless shoulder arthroplasty reported promising clinical and radiological outcomes in short to midterm follow-up. Long-term studies are needed to demonstrate the long-term value of these kind of implants.
我们系统地回顾了目前可用的无柄肩关节置换系统的研究文献。从确定的系列中,我们记录了适应症,结果衡量标准,和肱骨侧并发症。
我们确定了11项研究,分别保留了无茎解剖肩关节置换术植入物,2010年至2016年出版。这些研究包括929例,平均随访26个月(范围,6至72个月)。肱骨组件相关并发症的发生率介于0和7.9%之间。研究仅报道了少数肱骨组件并发症的孤立病例。一些关节成形术系统与放射学变化有关,但没有任何临床意义.
所有已发表的无柄肩关节成形术的研究都报道了短期至中期随访的临床和放射学结果。需要长期研究来证明这些植入物的长期价值。
