title: Impacted morsellised allograft and cemented cup in acetabular revision surgery. A five to nine year follow-up study.
abstract: Seventy cemented cups associated with impacted morsellised allograft in revision surgery in hips with an acetabular bone defect greater than 30% (Paprosky Grades 3A and 3B) were analyzed. The mean follow-up was 6.8 years. One hip showed cup migration and was re-revised; this represents a total cumulative probability of re-revision of the cup of 1.4 2.8%. Radiolucent lines were uncommon: six cups showed radiolucent lines in DeLee and Charnley zone 1, five in zones 1 and 2, one in all three zones, while one hip showed migration.Although the frequent use of a metallic mesh makes graft remodeling difficult to evaluate, six hips showed minor and one major bone resorption. The mid-term results with impacted allograft and cemented all-polyethylene cups are favourable in acetabular revision surgery. (Hip International 2002; 12: 281-8).
