What is the Procedure?
Revision total hip replacement is a more complicated treatment than primary total hip replacement, and it takes longer to complete. The procedure usually takes several hours.
To begin, your doctor will trace the incision line from your original total hip replacement surgery. However, the incision can be lengthened to allow for the removal of the old components. Your doctor will expose the hip joint after the incision is done.
Your doctor will evaluate the soft tissues in your hip after exposing the joint to ensure that they are clear of infection and other complications, such as a response to the metal components. He or she will examine all components of the prosthesis to see which have gotten worn, loose, or moved out of place.
Your doctor will next gently remove the original implant, preserving as much bone as possible. This is also removed if cement was utilized in the original total hip replacement. Removing the cement from the bone is a time-consuming operation that adds to the revision surgery's complexity and duration.
In order to remove a well-fixed stem, a controlled "fracture" of the femur (thighbone) is occasionally done. Once the replacement stem is in place, the femur will be reassembled.
After removing the original implants, your doctor will prepare the bone surfaces in the pelvis and femur for the revision implants. There may be considerable bone loss in certain places in some circumstances. Metal augments or bone grafts can be used to compensate for the skeletal deficiencies if this occurs.
Finally, the specialist revision implants will be inserted by your doctor. Several screws are frequently necessary to keep the new cup in place until the bone grows in. Your doctor will examine the joint's mobility to confirm that the implants are securely in place and that the ball is stable within the socket.
Prior to inserting and attaching the final components, special "trial" implants are frequently evaluated. A drain may be inserted into your hip to collect any remaining fluid or blood following surgery.
After surgery, you'll be taken to the recovery room, where you'll be observed for many hours while your anesthetic recovery progresses. You will be escorted to your hospital room after you wake up.
