Abstract
40 patients affected by primary and secondary acetabular bone stock defect that were operated using cemented and cementless hip replacement.
Bone defect was classified according to American Academy of orthopaedic surgery, different types of bone graft techniques and metal reinforcement were used.
Geometrical position of the acetabular component, cup integration, hip center and graft interposition were assessed, 95% of the cups were in the desired position with graft incorporation and remodeled with one case of partial sciatic affection, most of reconstructions in primary hips were done with cementless cups but most of reconstructions in defects following loosening were treated by cemented cups.
The results depend on the stability of the graft, cementing technique as well as cup position.
