Core Decompression for Avascular Necrosis of the Hip

Overview

This surgery removes bone tissue damaged by a problem called avascular necrosis. Taking away this bad bone makes space for healthy new bone to grow.

Preparation

To begin, you are numbed. You may be put to sleep. You'll lie on your back for the surgery. First, a small incision is made in your hip. A guide wire is passed through this incision. With the help of a video x-ray device called a "fluoroscope," the surgeon pushes the wire to the damaged bone in the head of your femur.

Decompression

Then, a drill is guided along the wire and to your femur. The surgeon drills one or more holes into the bone. The damaged bits of bone are removed from your body. This relieves pressure in your femur. It creates space where new blood vessels and bone can form. The space may be filled with graft material to help this new growth.

End of procedure

When the surgery is done, the incision is closed. You are watched in a recovery room for a brief time. Follow your surgeon's tips as you heal.
