Resurfacing of the glenohumeral joint has gained popularity since its first introduction in 1958. Advantages of resurfacing over conventional shoulder arthroplasty include preservation of humeral bone stock, closer replication of individual anatomy, reduction of periprosthetic fracture risk, non-violation of medullary canal, and ease of revision to a stemmed component if needed. We reviewed a group of patients with arthrosis of the glenohumeral joint who underwent humeral resurfacing, and who were at a minimum of two years post surgery. From January 2000 to March 2011, 51 humeral resurfacing procedures were performed in 49 patients. Patients were contacted for review, and assessed using patient reported outcome measures. An Oxford Shoulder score as well as a subjective satisfaction and outcome questionnaire was completed, as well as details regarding further surgery or revision. 2 patients had died, 11 patients were not contactable, and in 4 the medical files had been lost. In the remaining 32 shoulders, the average follow-up was 5.9 years. The mean age at time of surgery was 62.3 years (range 36 to 84).Introduction
