[Comparison of rheumatic and post-traumatic elbow joints after total elbow arthroplasty. Comprehensive and specific evaluation of clinical picture, function, and quality of life]

Abstract

Background: Patients with elbow destruction due to rheumatoid arthritis (RA) or trauma (PT) were compared to population-based normative data and to each other after total elbow arthroplasty.

Patients and methods: Pain, function, and biopsychosocial health were multidimensionally assessed by the generic Short Form 36 (SF-36), the condition-specific Disabilities of the Arm, Shoulder and Hand questionnaire (DASH), and the Patient Related Elbow Evaluation form (PREE) instrument and analyzed by uni- and multivariate methods.

Results: Compared to normative values, the examined 59 RA patients were significantly affected in the function scales of the SF-36 and in all DASH scales. The 20 PT patients were worse than the norm only in the DASH function. Function was lower in RA than in PT in the SF-36 scales and in the DASH (RA: 44.4, PT: 70.3, p<0.001). This difference was less distinct in the PREE.

Conclusion: Total elbow arthroplasty led to a pain-free outcome and normal quality of life, but failed to restore complete function. Functional deficits were larger in the RA patients and could also be measured by the SF-36, possibly due to polyarticular affection.
