Abstract

Background: Medium-term clinical results and survival of the Copeland resurfacing hemiarthroplasty of the shoulder (CRHA) in a large consecutive group are presented with a comparison of outcomes for underlying pathologies.

Methods: A consecutive series of patients undergoing CRHA over 14 years was retrospectively analysed with no exclusions. Patients had a minimum 2-year follow-up by an independent assessor. Functional outcome was assessed using the Oxford Shoulder Score (OSS) and Constant-Murley Score (CMS). Pain and satisfaction was assessed using a visual analogue score.

Results: 279 CRHAs were performed in 242 patients between 2002 and 2016. The mean follow-up was 6 years. The indication for surgery was osteoarthritis (OA) in 212, inflammatory arthropathy (RA) in 35, rotator cuff tear arthropathy (CTA) in 22 and avascular necrosis (AVN) in 2. For the OA group, 5-year survival was 90%, 10-year survival was 83% and mean survival was 13.2 years (95% CI 12.5-13.9). The mean OSS was 35.0 and mean CMS 49.9. CRHA for CTA had significantly poorer (p < 0.001) 5-year survival (55%), 10-year survival (41%) and mean survival (5.9 years, 95% CI 4.7-7.2). Mean OSS was 23.6 and mean CMS 30.3, which was poorer than for OA (p < 0.001). A subgroup analysis of OA patients found significantly better survival (p = 0.013) in those aged over 65 years but no difference in functional outcome.

Conclusion: CRHA remains a reasonable option for OA in patients with an intact rotator cuff and with sufficient bone stock, especially in those aged over 65 years. With poorer functional outcomes and survival, CRHA should not be offered in those with CTA.

Level of evidence: Level III (retrospective comparative study).
