A follow-up is given of the results of 40 arthroplasties with the non-cemented, vitallium-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 scors according to a modification of merle d'Aubigné'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.
对37例骨关节炎患者使用非骨水泥型、维他利ium对维他利ium承重环全髋关节假体进行的40例关节成形术的结果进行了随访。手术指征为关节疼痛难忍且僵硬。手术由两名骨科专家进行。根据对默尔·德奥布涅分类法的修改进行的评分显示，52.5%的手术结果为优秀或至少良好，27.5%的手术结果为尚可。1例假体因深部感染被取出。死亡率为零。20%的患者总分在0至7分之间，表明改善甚微或没有改善。松动是主要问题，尽管在许多情况下患者耐受性良好。
