We evaluated the long-term survival and patient reported outcome of the Copeland mark III humeral resurfacing hemi-arthroplasty (Biomet, Warsaw, Indiana). At a UK District General Hospital 95 shoulder replacements in 85 patients were performed from 1994 to 2003 (mean age 68.9). At the time of follow-up (mean of 12 years, range 8.7–18.0) 49 patients had survived. This study group were posted Oxford Shoulder Score (OSS) and SF-12 questionnaires and their case notes were reviewed. There was an 82% response rate. The responders comprised 46 shoulders in 40 patients. 40 shoulders had a pre-operative diagnosis of osteoarthritis and 6 had other pathologies. The median OSS was 36. The median functional score was 24 (IQR: 9.5), where 32 is the best. The median pain score was 13 (IQR: 7) with 16 being the best score. There was a median SF 12 score of 31 (IQR: 3), where the maximum score is 47. There were 3 revision operations and 95% survivorship at 18 years, according to Kaplan Meier survival analysis. The Copeland mark III hemi-arthroplasty prosthesis has a good long term survival, few post-operative complications and a good functional outcome in an elderly population. We would advocate its use in this patient group.
