Revision of total hip replacement with solid cortico-spongious bone graft for medial acetabular disruption.
In revision of failed total hip replacements with disruption of the medial acetabular wall the use of autogenous solid cortico-spongious bone graft proved to be a successful surgical procedure. In 7/8 revisions followed for 2-3 years, the bone grafts healed, as seen radiographically on plain film or by conventional tomography and no further acetabular protrusion occurred. Two of these seven hips had a radiolucent zone of 2-5 mm at the bone-cement interface at the inferior part of the cup. In the eighth hip the bone graft was resorbed/eroded and the cup had migrated 4 mm in the mediocranial direction.
