MID-TERM OUTCOME OF THE GSB III TOTAL ELBOW ARTHROPLASTY

Avon Orthopaedic Centre, Southmead Hospital, Bristol, UK

Aims: To review the results from a series of GSB III total elbow arthroplasties performed at an independent centre. Between 1996 and 2004 the senior author performed 58 total elbow arthroplasties in 44 patients (10 males, 34 females) using the GSB III implant. These were reviewed and the outcome assessed through the use of a patient-answered questionnaire and clinical and radiological review. Mean age was 65 (49 to 84 years). Indications for surgery included rheumatoid arthritis (46 elbows) and post-traumatic osteoarthritis (11 elbows). Mean F/up was 4.1 years (0.8 to 8.5 years). 4 patients had died (6 elbows) and 4 patients (4 elbows) were unavailable for review. 2 of the implants had been revised (1x aseptic loosening, 1x deep infection), leaving a total of 46 elbows available for review. The survival rate at a mean of 4 years was 98% with aseptic loosening as the endpoint. Complications included 1 case of intraoperative fracture and 1 persistent ulnar neuritis. Overall patient satisfaction was high. The mean Mayo Elbow Performance Score was 83 out of 100 (range, 34 to 100) and mean Liverpool Elbow Score was 8 out of 10 (range, 1 to 10).

Conclusion: Previous studies of outcome following total elbow arthroplasty using the GSB III elbow prosthesis at independent centres have shown satisfactory results, but have looked at small groups of patients. Our results offer more robust data to show that the medium term outcome following total elbow arthroplasty using the GSB III prosthesis is satisfactory.
