    Abstract:
    OBJECTIVE: To retrospectively review the results of Coonrad-Morrey semi-constrained total elbow arthroplasty (TEA) for the treatment of different elbow disorders. METHODS: Between December 2003 and April 2008, 30 patients with different kinds of elbow disorders including elbow fracture, non-healing elbow fracture, rheumatoid arthritis and osteoarthritis were treated with TEA using the semi-constrained Coonrad-Morrey elbow replacement prostheses. One patient had bilateral total elbow replacements. There were 22 females and 8 males, with a mean age of 66 years (47 to 78). RESULTS: Twenty patients (21 elbows) were available for review. The average length of follow-up was 35 months (from 12 to 52 months). The mean Mayo elbow performance score was 84 points. Excellent results were achieved in 6 elbows (28%), 11 elbows had good outcome (52%), 2 elbows had improvement (10%), while the other 2 elbows had no improvement (10%). The 2 elbows with distal humeral fractures, had no pain after treatment but developed heterotopic ossification, which caused stiffness and lower the Mayo elbow performance score. One delayed healing of the wound, one patient experienced temporary radial nerve hypesthesia and one elbow showed transparent region around the implant without radiological sign of loosening in the implanted prostheses. CONCLUSIONS: This study reveals good to excellent outcome with the use of semi-constrained TEA for the treatment of rheumatoid arthritis, elbow fracture, osteoarthritis and non-healing elbow fractures in elder patients. The non-healing elbow fractures in elder patients would accompany with severe osteoporosis and comminuted fracture, which would affect the result of open reduction internal fixation. So TEA may be one optimal treatment for these patients.
