Revision Hip with Allograft


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.

Femur Replacement

Femur replacement is used to remove a large portion of a severely damaged femur and replace it with allograft. First, the component and the damaged bone are removed. Then, an allograft femur is shaped to fit in its place. A new metal implant is inserted into the allograft. Acrylic cement may be used. Wires are then used to secure the allograft.

Socket Loss Repair

Socket loss repair uses allograft to repair the hip socket when a large portion of hip bone is damaged or lost. First, the damaged bone is removed and the area is cleaned. The surgeon then selects a portion of allograft femur (in this example, the head of the femur is used) and secures the bone to the damaged socket area. The surgeon reshapes the allograft bone to create a new socket.

Socket Replacement

A new metal socket shell and liner are pressed into place. Screws may be needed to secure the shell, and cement may be used to secure the liner.

End of Procedure

The reconstructed femur and hip socket are connected to form the new hip joint.
