Favorable results of acetabular reconstruction with impacted morsellized bone grafts in patients younger than 50 years - A 10-to 18-year follow-up study of 34 cemented total hip arthroplasties

We report a long-term review of 41 acetabular reconstructions using impacte d morsellized bone grafts and a cemented total hip arthroplasty (THA) in pa tients younger than 50 (22-49; average 38) years. Reconstruction was perfor med in 23 primary THA (19 patients) and 18 revision THA (17 patients), 3 pa tients were lost to follow-up and 3 (4 hips) died within 10 years of surger y; none had a revision. Thus, 34 hips (30 patients) were reviewed with an a verage follow-up of 13 (10-18) years, In 2 hips, a revision was performed for aseptic loosening of the acetabular component 7 and 11 years after surgery. One additional cup was revised aft er 12 years during a femoral stem revision due to wear and matching problem s, but was well tired, The survival rate of the acetabular reconstruction t echnique was 94% (95% CI: 90-98%).
