The treatment of acetabular bone defects presents a great challenge in revision @entity572 ( @entity572 ). The purpose of this study was to evaluate the clinical and radiological outcome of revision @entity572 using jumbo cups for acetabular reconstruction after applying the bone-grafting technique. We studied 17 @entity1 with acetabular defects ranging from Type 2A to Type 3A according to Paprosky's classification. According to the AAOS-score twelve @entity1 were classified as Type II and five @entity1 as Type III. Uncemented press-fit cups with an outer diameter larger than 64 mm were used in all cases. Fifteen @entity1 received morselized bone allografts. In eight @entity1 an additional screw fixation was necessary. The mean follow-up period was 82 months (range 33-149). The mean Harris Hip Score was preoperatively 62 and at the time of the last follow-up examination 83 points (p = 0.007). Two acetabular components failed, one due to @entity1349 and another one due to septic loosening. There was a trend of displacement of the femoral head centre towards the infero-lateral position after using jumbo cups that approached statistical significance (p = 0.065). Closure of acetabular defects of Types 2A to 3A according to Paprosky's classification and type II to III according to the AAOS-score respectively can be satisfactorily accomplished using jumbo cups after applying the bone-grafting technique.
