Revision Hip Replacement
Revision hip replacement is a complex surgical procedure in which all or part of a previously implanted hip-joint is replaced with a new artificial hip-joint. At times, hip replacement implants can wear out for various reasons and may need to be replaced with the help of a surgical procedure known as revision hip replacement surgery.
Revision hip replacement is advised in patients with the following conditions:
Revision hip replacement surgery is typically performed under general or regional anesthesia. During the procedure, your surgeon will make an incision over the hip to expose the hip joint. Then the femur is dislocated from the acetabulum so that the old plastic liner and the metal socket can be removed from the acetabulum.
After removal, the acetabulum is prepared for the new component. Then the new metal shell is inserted into the socket using screws or special cement. A liner made of plastic, ceramic or metal is placed inside the metal socket.
Next, the new femoral implant is inserted into the femur either by a press fit or using bone cement. The femoral head component made of metal or ceramic is placed on the femoral stem. All the new components are secured in place to form the new hip joint. The muscles and tendons around the new joint are repairedif needed and the incision is closed.
After undergoing revision hip replacement, you must take special care to prevent the new joint from dislocating and to ensure proper healing.
As with any major surgical procedure, there are certain potential risks and complications involved with revision hip replacement surgery. The possible complications after revision hip replacement include:
- Fracture of the femur or pelvis
- Injury to nerves or blood vessels
- Formation of blood clots in the leg veins
- Leg length inequality
- Hip prosthesis may wear out
- Failure to relieve pain
