Core Decompression for Avascular Necrosis of the Hip

This procedure treats avascular necrosis by removing degenerated and dead bone tissue and creating room for new, healthy tissue to grow. It typically works best for people who are in the earliest stages of the disease.

An incision is made on the side of the thigh to allow access to the side of the femur. A guide wire is inserted and placed against the femur at the drill site. The location is confirmed with the aid of a fluoroscope.

Removing The Damaged Bone
The surgeon uses a drill to carefully create one or more channels into the femur and through the degenerated bone tissue. The damaged bits of bone are removed, creating open space inside the bone that will allow healthy blood vessels and bone to develop. The space may also be filled with a gel, morselized bone or bone graft.

End Of Procedure And After Care
The incision is closed and bandaged. The patient will be required to use crutches for at least six weeks after the procedure to allow the femur to strengthen.
