ABSTRACT
Objective To discuss the indication, surgical technique and curative effect of humeral head replacement in treatment of complex proximal humerus fracture in old patients. Methods From 2000 to 2006, 23 patients with complex proximal humerus fractures were treated with humeral head replacement and fixated with bone cement in old patients. Rehabilitation training was performed after operation.Results Of all, 19 patients were followed up for average 1.8 years, which showed no infection, nerve injury or periprosthetic fracture except for one patient with semiluxation. NEER score system was used to evaluate the function joint prosthesis. Mean NEER score was 82.1 points, including 80-89 points ( satisfactory) in 17 patients and 70-79 points (unsatisfactory) in 2, with satisfaction rate of 89%. No patient needed revision. Conclusion With strict indication, active reconstruction of rotating cuff and stable structure of the joint, planned postoperative rehabilitation training, the humeral head replacement is a good method for treating complex proximal humerus fractures in the old patients.
