Aim. To evaluate results of Aequalis humeral head resurfacing in patients with end-stage glenohumeral arthritis at a minimum followup of two years. Patients and Methods. Twenty-one consecutive patients underwent humeral head resurfacing hemiarthroplasty between 2007 and 2009.Three patients did not fulfill the inclusion criteria. 18 patients with mean age of 75.1 years (range 58–91 years) and a mean duration of preoperative symptoms of 33.6 months (range 6–120 months) were analyzed. Patients’ self-reportedOxford shoulder score (OSS)was collected prospectively andwas used as an assessment tool tomeasure final outcome. Results.Themean initial OSSwas 15 (range 3–29).The score improved by an average of 19.5 points at amean followup of 36.3months (range 24–54 months) to reach a mean final OSS of 34.5 (range 6–47). The improvement of OSS was highly significant with a two-taile
