Clinical Outcomes of Semiconstrained Total Elbow Arthroplasty : Non-traumatic Arthritisversus Traumatic Arthritis / 대한정형외과학회잡지

ABSTRACT

PURPOSE: This study evaluated the clinical and radiological outcomes of semiconstrained total elbow arthroplasty. MATERIALS AND METHODS: Thirty-nine elbows with semiconstrained total elbow arthroplasty and who were followed up for at least 3 years were enrolled in this study. There were 29 and 10 cases in the non-traumatic arthritis and traumatic arthritis groups, respectively. The mean age at the time of surgery was 53.9 years, and the mean follow-up period was 54 months. RESULTS: At the last follow-up, the pain score during motion decreased from 7.37 to 1.23. The Mayo elbow performance score was 86. The mean loss of terminal extension improved from 32degrees to 11degrees and the mean maximum flexion improved from 90.3degrees to 125.2degrees. Radiology analysis, 15 elbows showed radiolucency and 8 elbows showed loosening. There were 13 cases of radiolucency and 7 cases of loosening in the non-traumatic arthritis group. In the traumatic arthritis group, there were 2 cases of radiolucency and 1 case of loosening. CONCLUSION: Semiconstrained total elbow arthroplasty for non-traumatic and traumatic arthritis of the elbow produced satisfactory functional results. The non-traumatic arthritis group had a higher incidence of radiolucency and loosening than the traumatic group.
