Overview
This procedure is used to remove excess bone growth and reshape the hip joint to allow for proper joint movement.
Preparation
The patient is positioned so that the front of the hip is clearly visible to the physician, and the area is cleaned and sterilized. Local anesthesia is administered to numb the injection site, and a sedative is provided to relax the patient. General anesthesia may sometimes be used.
Accessing the Joint
The surgeon makes an incision over the hip and carefully separates the femur from the hip socket.
Reshaping the Joint
The surgeon uses a burr, chisel or rasp to trim away excess bone growth on the head of the femur or the socket. In many cases, both the acetabulum and femoral head require treatment. The femur is reshaped so that it is round and smooth, allowing it to glide freely in the socket cup. Overhanging bone around the rim of the cup is removed so that it does not impact the head of the femur.
Repairing Other Damage
The joint is examined for signs of damage. If the labrum is torn, or if articular cartilage is damaged, the surgeon will make the necessary repairs.
End of Procedure and After Care
The incisions are closed with sutures or surgical staples. The hip is bandaged. Physical therapy will be needed, and crutches or a walker should be used to avoid putting weight on the hip for two to six weeks.
