title: Acetabular protrusio: a problem in depth.
abstract: We have found that positioning of the acetabular implant into the anatomic acetabular location is challenging and an important consideration. This can most easily be achieved with careful medial reaming, central bone grafting, and cup placement on the rim of the native socket supplemented with screw fixation. Our data suggest that uncemented acetabular components have better survivorship than cemented cups for the treatment of protrusio deformity about the hip.
