Abstract

Aims: We review our experience of Coonrad-Morrey total elbow arthroplasty (TEA) for fractures of the distal humerus in non-rheumatoid patients with a minimum of ten years follow-up.

Patients and methods: TEA through a triceps splitting approach was peformed in 37 non-rheumatoid patients for a fracture of the distal humerus between 1996 and 2004. One patient could not be traced and 17 had died before the tenth anniversary of their surgery. This left 19 patients with a minimum follow-up of ten years to form the study group. Of these, 13 patients were alive at the time of final review. The other six had died, but after the tenth anniversary of their elbow arthroplasty. Their clinical and radiological data were included in the study.

Results: The mean follow-up of the 19 patients was 156 months (120 to 210). Two patients in the study group had undergone revision. One further patient had undergone a two-stage revision for infection but died before ten-year follow-up. Six other patients in the study group had evidence of loosening or wear of their bushings. Two were clinically symptomatic and were offered revision surgery. Male patients showed higher incidence of loosening and wear. Survivorship, with revision and definite loosening as end-points, was 89.5% at ten years in those patients followed for a minimum of ten years and 86% in the whole group of 36 patients.

Conclusion: This study shows that only 53% of non-rheumatoid patients who undergo TEA for a fracture of the distal humerus survive to the tenth anniversary of their index procedure. For those that survive, TEA provides acceptable outcomes in terms of function and implant survival.

Take home message: The surgeons undertaking these procedures should be aware of the long-term revision rates and also the gender difference in the rates of loosening.
