Introduction
The results of different prostheses used for total elbow arthroplasty (TEA) in rheumatoid arthritis (RA) have been reported
in only a few studies. Small differences in survival or function between implants have been reported. We retrospectively evaluated
the results of 42 Souter-Strathclyde and Kudo TEAs.
Materials and methods
Between 1988 and 1994, 21 consecutive patients with RA and severe elbow destruction underwent a Souter-Strathclyde TEA. Between
1994 and 1998, another group comprising 21 consecutive patients with RA with severe elbow destruction underwent a Kudo TEA.
Results
There were six revisions for the groups combined, including four aseptic loosenings, one fracture and one liner wear and metallosis.
The 5-year survival for the Souter-Strathclyde and the Kudo were 85% (95% CI 69–100) and 95% (95% CI 85–100), respectively.
The difference between the groups was not statistically significant as tested by the Cox regression analysis. The majority
of the patients were free of pain at follow-up. More than half of the patients were able to perform only light housekeeping
tasks and a considerable proportion even had difficulties in maintaining personal hygiene. The elbow range of motion improved
only slightly after the operation.
Conclusion
Both the Souter-Strathclyde and the Kudo TEAs provide good pain relief in the arthritic elbow leading to high patient satisfaction
despite the residual disabilities. Only small differences in the results between the Souter-Strathclyde and the Kudo TEAs
were found. More than half of the patients were able to perform only light housekeeping tasks and a considerable proportion
even had difficulties in maintaining personal hygiene. The elbow range of motion improved only slightly after the operation.
