title: Cemented total hip arthroplasty with impacted morcellized bone-grafts to restore acetabular bone defects in congenital hip dysplasia.
abstract: We evaluated the results of 27 acetabular reconstructions in 21 patients with secondary osteoarthritis resulting from congenital dysplasia of the hip in which the acetabular bone defects were restored with impacted morcellized bone-grafts in combination with a cemented cup. At an average follow-up of 7 years, 7 months (range, 5-15 years), 2 hips were revised. One cup was revised after 27 months for sciatic nerve problems; the other hip was revised for aseptic loosening of the cup at 12 years' follow-up. The cumulative survival of the acetabular reconstruction was 96.3% at 5- and 10-year intervals. Additionally, 2 hips (7.7%) showed stable radiolucent lines in zone III without migration of the cup. None of the cemented stems were revised. The bone impaction grafting technique is a safe and attractive method to restore bone deficiencies in dysplastic hips.
