Merolla, P. Bianchi, N. Lollino, R. Rossi, P. Paladini, G. Porcellini] Purpose: Humeral resurfacing is a treatment option to conventional shoulder arthroplasty, conferring the advantages to preserve the bone stock and the normal joint geometry. Aim of the current study was to report clinical and radiographic mid-term outcomes in a population of 60 patients, aged 50years or younger, who underwent shoulder resurfacing in osteoarthritis. Methods: The mean age was 48±8.4, 36 were male and 24 female, dominant arm in 43 cases. Glenoid arthritis was treated in 36 cases (60%) using a meniscus allograft in 22 cases, biologic patch in 4 cases and microfractures in 10 cases. Clinical and radiographic assessment was performed with Constant-Murley score and standard X-ray. Results: At an average follow-up of 44months, the mean values of the constant score increased of 30 points (p<0.05), the pain decreased of 4.56 points (p<0.05) and the Simple Shoulder Test increased of 4.3 points (p<0.05). We found lower scores (p>0.05) in 9 patients (15%) treated for glenoid arthritis using homologous meniscus (7 cases) and biologic patch (2 cases). A significant narrowing of joint space (5.92mm postoperative versus 1.65mm at 37months) (p<0.05) was found in the 22 cases treated with meniscus interposition. In 4 cases with type A2 preoperative glenoid morphology and in 9 cases type B1, we registered significantly lower scores compared with the overall study population (p<0.01). Five unsatisfied patients (7%), underwent to meniscus removal and glenoid reaming in 3 cases and conversion in total shoulder arthroplasty in 2 cases. Conclusions: Resurfacing arthroplasty is an effective device in young patients with advanced glenohumeral arthropathy; however, the high rate of postoperative glenoid erosion and the failure of biologic allograft lead us to consider glenoid replacement as the best option to improve clinical outcomes.
