Acetabular revision with impacted grafting and a reinforcement ring: 42 patients followed for a mean of 10 years.
We analyzed the outcome of 42 cemented cup revisions (40 patients) with morselized bone grafts and a reinforcement ring after median 10 (7-16) years. The acetabular component migrated a mean of 7 (5-8) mm in 5 hips. The migration stopped after 2 years except in 1 hip, the only one revised because of mechanical loosening. 3 other hips were revised because of infection. Among the other 38 hips (36 patients), the Merle d'Aubigné score increased from 9 to 15 points.
