Abstract:
Objective To evaluate the outcome of unconstrained shoulder arthroplasty for severe injury of proximal part of the humerus.Methods Twelve eases were all treated with unconstrained shoul- der arthroplasty.Six patients with complex fractures of proximal humerus and four with bone tumor in the proximal part of the humerus used hemiarthroplasty and two patients with osteoarthritis were managed with total shoulder arthroplasty.Cemented prostheses were used in all the cases.Results The average age was 65 years and the follow-up was 2.3 years.Two cases of complex fractures had light pain with limited external rotation of the shoulder.No pain or prosthetic stems loosening were found,and the range of motion and the function of the shoulder were satisfactory in other cases.Conclusion Unconstrained shoulder arthroplasty is a satisfactory and safe technique for severe injury of proximal humerus.
