Abstract:
Objective To evaluate clinical results of arthroplasty with the UNIVERS 3-D prosthesis in unstable shoulder arthritis. Methods 16 cases, which were 10 males and 6 females aging from 35 to 79 years (mean, 56.3 years), underwent shoulder arthroplasty with the UNIVERS 3-D prosthesis because of unstable arthritis. The patients were evaluated before surgery, at 12 months and the most recent follow-up with an average follow-up of 30.8 months(mean, 12-50 months) by Constant and normalised Constant score, and reviewed by the radiological analysis on preoperative and postoperative X-rays including AP, scapular and axillary views. Constant and normalised Constant score improvements at 12 months and the most recent follow-up evaluation were compared with the preoperative scores using paired-samples t test. Results 1) 8 out of 11(72.7%) cases with mild inferior humeral or glenoid exostosis. 2) The Constant score improved from 43.8?13(normalized Constant score, 51.36%?15.40% ) to 70.6?17.69(normalized Constant score, 86.44%?22.12%). The pain, activity, mobility and strength scores had been improved obviously. 3)Only one case had the radiolucent line around the uncemented humeral component with radiolucent index of less than 1. No any periglenoid component radiolucency, no shift or subsidence in humeral component, no migration and tilt in glenoid component, no change and loosening in the junction bolt between humeral stem and head. 4) Two cases were experienced postoperative complications including impingement of prosthesis with osteophytes, and PE-inlay loosening received revision surgery. Conclusion Excellent clinical results can be obtained by the shoulder arthroplasty using the UNIVERS 3-D prosthesis with low incidence of radiolucency and postoperative complication.
