Aims: Aim of the work is evaluation of outcome after reconstruction of acetabular bone stock deþcit in revision hip alloplastics. Methods: Material consists 113 patients with septic and aseptic acetabulum loosening after THA, 31 (27,4%) with cementless and 82 (72,6%) with cemented THA. For evaluation of the functional outcome has been used AAOS scale. Loosening was evaluated on X-rays on behalf of symptoms described by De Lee and Charnley. Surgical tactic was based on Paprosky anatomical bone stock deþcit evaluation Results: Functional Harris hip scores after realloplastic showed improving in passive motion and lowering of pain complaints. There has been concluded full graft in osteointegration in cases with stabile placement of thick cancellous bone graft, with good contact between graft-bone interface and cup. Conclusions: Solid liophylized and milled cancellous bone grafts, used in reconstruction of acetabulum, can remodel and osteointegrate even in cemented technique if there is a sufþcient contact between acetabulum wall and graft. It is possible to obtain good long-term functional and radiological results with usage of operative technique based on remodeling of bone grafts.
