| Popis: | Sixty eight cementless acetabular revisions were performed using impacted morsellized bone graft and the Harris Galante 1 porous coated component (HGP 1). Acetabular defects were graded according to the American Association of Orthopaedic Surgeons classification. Twenty nine (43%) were contained (Type 2 cavitatory) and thirty nine (57%) uncontained (Types 1 or 3 - segmental or combined) defects. The patients were followed prospectively for a mean of five years (range two to ten years). Radiological evidence of graft remodelling was seen in twenty two hips. Progressive radiolucent lines were present in eight cases (12%). Two screws broke. There were two cases of deep infection. Radiological failure, with a change in cup angle of greater than 5 degrees or migration of greater than 5 mm, was seen in six cases (9%). All six had uncontained defects (segmental or combined). Gratifying medium term results have been obtained after reconstruction of contained acetabular defects using impacted morsellized bone graft and the cementless HGP 1 cup. Inadequate graft support in uncontained defects resulted in six cases of failure. |
