Hemiarthroplasty with concentric reaming had equivalent outcomes to total shoulder arthroplasty

Published results showed high and equivalent rates of sporting, clinical and radiographic outcomes between patients who underwent hemiarthroplasty with concentric reaming and patients who underwent anatomical total shoulder arthroplasty.
Anirudh K. Gowd , MD, and colleagues surveyed 26 patients who underwent hemiarthroplasty with concentric reaming and 30 patients who underwent anatomic total shoulder arthroplasty (TSA) for end-stage glenohumeral arthritis to determine the level of sport and satisfaction after surgery. Researchers matched patients based on age, BMI, sex and hand dominance.
Results showed no statistical differences regarding patients who reported no postoperative problems, reoperation, return to overall sport, return to high-demand upper extremity sport and return to the same or better level of intensity sport between the two groups. Researchers found patients in the hemiarthroplasty group returned to sport at a mean of approximately 7.5 months vs. 6.2 months in the anatomic TSA group. The hemiarthroplasty group had radiographic measurements of medialization and postoperative decentering that were equivalent to the anatomic TSA group, according to results.
“Patients receiving hemiarthroplasty with concentric glenoid resurfacing achieved a high rate of return to low- and high-intensity sport with a mean follow-up of over 6 years. These outcomes were equivalent to that of a match-paired cohort of patients receiving total shoulder arthroplasty,” Gowd told Healio.com/Orthopedics. “This study emphasizes the safety and efficacy of performing this operation for well-indicated and active patients.” – by Casey Tingle

Perspective
Back to TopPaul J. Cagle Jr., MD
The number of individuals who will need a shoulder replacement is going to increase dramatically during the next 10 to 15 years, and this increase will include both patients older and younger than the age of 55 years. With an increasing number of younger patients requiring an arthroplasty, data is needed to address the capacity and risks associated with the return to an active lifestyle.
Grant H. Garcia, MD, and colleagues address the issue by investigating patients interested in returning to sports. Through a matched-pair analysis, an assessment was performed comparing a hemiarthroplasty with concentric glenoid reaming to a conventional total shoulder arthroplasty. The hemiarthroplasty with concentric glenoid reaming was demonstrated to perform well in regard to patient satisfaction, reoperation rates and, most importantly, in return to sports. As early glenoid component loosening is a primary concern for patients who want to remain active after a shoulder arthroplasty, non-glenoid implant options are attractive. This paper demonstrates concentric reaming with a hemiarthroplasty is a viable and attractive option for patients who want to return to sports after a shoulder arthroplasty.
