Treatment of fractures of the humeral head by cemented and cementless hemiarthroplasty. Our experience.
Patients submitted to shoulder hemiarthroplasty for the treatment of fracture of the humeral head were analyzed. The study was conducted from 1991 to June 2001 using 2 different prosthetic models: the Neer cemented prosthesis and the Randelli cementless prosthesis. The authors were able to evaluate 93 cases out of 148 operated on. A review of data revealed the essential importance of reconstruction of the tuberosity and rehabilitation. It was also observed that the age of the patient and the severity of the fracture did not in any way influence results. X-ray examinations did not shed light on loosening phenomena in prosthetic implants. Erosion of the glenoid was observed only when two factors coexisted: incorrect position of the prosthesis and low mobility of the shoulder. The study allowed us to reveal numerous prognostic elements, both favorable and adverse, and to measure their importance and priority.
