Magosch P, et al. - This study was attempted to assess the long-term results of shoulder arthroplasty applying a stemless humeral head component. Researchers documented stemless humeral head replacement prospectively since 2005. After a mean of 126 months (range, 105-157 months), seventy-five patients with a mean age of 57 years at surgery (40 Hemi- (HSA), 35 total shoulder arthroplasties, 38 females, 37 male) were clinically and radiologically followed-up. After a mean of 11 years, stemless humeral head replacement exhibited no loosening and a significant improvement of shoulder function. The results of this study demonstrate that clinical and radiological long-term outcomes as well as the survivorship of anatomic shoulder arthroplasty using a stemless humeral head implant are comparable to the long-term results of standard stemmed anatomic shoulder arthroplasty.
