Ring Total Hip Replacement in Osteoarthrosis

Abstract

A follow-up is given of the results of 40 arthroplasties with the non-cemented, vitalliuBQ-to-vitallium bearing Ring total hip prosthesis in 37 patients with osteoarthrosis. Operative indication was an intolerably painful and stiff joint. The surgery was performed by two specialists in orthopaedics. Point scores according to a modification of Merle d'Aubigne's classification showed excellent or at least good results in 52.5 per cent, and fair results in 27.5 per cent of the operations. One prosthesis was removed because of deep infection. The mortality rate was zero. in 20 per cent the total score was between 0 and 7, signifying little or no improvement. Loosening was the main problem even although it was in many cases well tolerated by the patients.
