Revision hip is performed to replace worn artificial hip parts and damaged bone with new metal, plastic or ceramic components. Several revision options are available, chosen based on the condition of the patient’s bones. This animation will show multiple revision techniques.

The Endosteal technique may be used if the femur (thigh bone) is missing bone in its core. The surgeon removes the old femur component and packs morselized bone into the femur cavity. The new femur component is then inserted into the prepared femur. The additional bone material holds the new component securely in place.

Segmented Replacement
Segmented replacement may be used if portions of the femur are damaged or missing. The bad areas are repaired using donor bone, called allograft. First, the component is removed and the damaged areas are cleaned up. Then, a new metal implant is inserted. Acrylic cement may be used. Finally, pieces of allograft are shaped to fill the missing areas and secured to the femur with wires.
