Abstract
Aims: To test the outcome of acetabular revisons with impacted morsellized bone grafts and a cemented cup at a minimum follow-up of 15 years. Methods: Between 1979–1986 62 acetabular revisions (58 patients) were performed with impacted bone grafts and a cemented cup. Two cases (2 hips) were lost to FU. The average age at operation was 59.1 years. The indication was aseptic in 56 and septic loosening in 4 hips. Defects were AAOS-classiþed as ñcavitaryñ in 37 and ñcombinedñ 23 cases. Femoral-head allografts were used. Acetabular re-revisions were determined, the HHS obtained and radiographs analyzed. Results: Nineteen cases (20 hips) died within þfteen years after the operation, none had a re-revision. Eleven acetabular re-revisions were performed: 2 septic loosenings (3 and 6 years p.o.), 7 aseptic loosenings (6, 9, 11, 12, 13, 14, 14 year p.o.) and two for cup wear (12 and 17 yrs p.o.). The average HHS at follow-up was 86 (50–100). There were no additional radiographic failures. Using Kaplan-Meier analysis the survival with endpoint revision for any reason was 79% at 15 years and 71% at 20 years; for aseptic loosening of the cup 84% at 15 years and 84% at 20 years. Conclusions: This technique is attractive to reconstruct acetabular bone stock loss.
