During the second half of the 1900s, total elbow joint replacement began its ascent. Since then, many prosthetic models have been used. The main objective of elbow joint replacement in arthritic diseases is to decrease pain, increase joint stability and improve overall range of motion. In this study, 18 patients affected with elbow arthritis were treated with the Coonrad-Morrey and Discovery total elbow prostheses. All patients were assessed clinically before and after surgery using the Mayo Elbow Performance Score, the Disabilities of the Arm, Shoulder and Hand questionnaire and through radiograph analysis. Excellent and good results were observed in 88.9% of the cases at a mean follow-up of 5 years. Significant statistical differences in all parameters between preoperative and final follow-up values confirm the efficacy of these devices.
