Midterm outcomes for stemless hemiarthroplasty for glenohumeral osteoarthritis A retrospective study
AuthorRobertsen, Marit Katarina
Osteoarthritis is the most common form of arthritis. For glenohumeral osteoarthritis the gold standard treatment for end stage disease is arthroplasty with stemmed prosthesis. The trend surrounding shoulder arthroplasty focuses on reducing stem-related complication, but mid- to long-term studies on stemless hemiarthroplasty are needed to evaluate durability. Our hypothesis was that stemless hemiarthroplasty is a good and reliable alternative for treatment of shoulder OA. In this retrospective study 21 shoulders in 17 patients with glenohumeral osteoarthritis were treated with the Eclipse stemless shoulder prosthesis for hemiarthroplasty of the shoulder between 2010 and 2016. Mean follow up time was 7 years. Functional outcomes were assessed using VAS, ASES and CS, while radiological changes were evaluated on standard radiographs. At last follow up time, there was significant improvement of VAS, ASES and CS from (7.5) to (1.8) p< 0.05, (36.4) to (84.1) p<0.05, and (33.5) to (79.6) p<0.05 respectively. In addition, there was no clinically significant radiological changes. The results of the present study revealed significant clinical improvements, while minimal radiological changes without clinical significance was observed. These results indicate stemless HSA as a simple, safe and reliable method for treating shoulder osteoarthritis.
