Impaction Bone Technique at the Acetabular Side

There is an ever-increasing number of failed hip arthroplasties displaying massive deficiencies of acetabular bone stock combined with segmental and cavitary defects [1-5]. Unfortunately, no single technique is likely to provide a olution to span the full spectrum of possible acetabular defects. But contained

acetabular defects can generally be treated by grafting of the defects and inserting a hemispherical acetabular component using screws and no cement [6-9].
