PURPOSE: To report the clinical and radiographic results and complications of the Delta III reverse prosthesis. METHODS: 24 women and 2 men aged 62 to 84 (mean, 75) years underwent total shoulder replacement using the Delta III reverse prosthesis. Patient diagnoses were massive rotator cuff tear (n=20), disabling sequelae of proximal humeral fractures (n=3), and failure of an unconstrained arthroplasty (n=3). Clinical and functional results were assessed using the Constant scale. Active range of motion (ROM) was measured. Scapular notching and radiolucent lines around the humeral component were evaluated using radiographs. Patient satisfaction of the treatment was evaluated by a direct interview. RESULTS: 23 patients were followed up for 26 to 84 (mean, 42) months. Two patients had loosening of the glenoid component (at 6 months and 5 years) and underwent revision surgery. There were no instances of infection, instability, or acromial fracture. Only active elevation improved significantly after surgery, as did both the absolute and adjusted Constant scores. 12 patients were completely pain-free, 9 complained of slight pain, and one of moderate pain. The severity of scapular notching progressed with time. 15 patients were satisfied with the treatment, 6 were partially satisfied, and 2 were not satisfied. CONCLUSION: The Delta III prosthesis restores shoulder function but has biomechanical limits. Its use should be limited to elderly patients with severe impairment of the glenohumeral joint. Scapular notching is a main concern for the long-term survival of the implant.
