Abstract

We studied the short-term results of non-constrained total elbow arthroplasty in patients with rheumatoid arthritis (RA).<BR>Eight elbows in seven patients were followed up for this study. Prior to surgery, the elbows were graded 4 or 5 according to Larsen radiological criteria. The patients were followed up for an average of 14.5 months (range: 3 months to 2 years 5 months).<BR>According to Kudos category, seven elbows had painful instability, and one had painful stiffness. The results, assessed according to the scoring system of the Japanese Orthopaedic Association, revealed remarkable improvement in pain and daily activities. Average rating of the elbows improved from 35.1 to 78.1 points.<BR>We would like to emphasize that the use of a non-constrained prosthesis necessitates greater attention to the operative technique, including insertion of components and repair of soft tissue balance. In conclusion, total elbow arthroplasty is considered to be a valuable procedure for restoring daily life activities of patients with rheumatoid arthritis.
