What are the implants used in a revision hip surgery?
In revision hip arthroplasty, compared with primary total hip arthroplasty, the environment of the hip joint is poor, and therefore, an implant appropriate for the purpose of the revision should be selected.
The total revision hip implant is comprised of four parts:
- A metal hip stem that is inserted into the top of your thighbone
- A metal cup which holds the cup liner
- A cup liner which holds the femoral head
- The femoral head or ball which is attached to the top of the hip stem and is inserted into the liner to form the ball-and-socket joint.
Hip revision implants are not one-size-fits-all, therefore your surgeon will choose the right hip implant for your body. Depending on the type of revision surgery needed (e.g. acetabular cup revison), different implants and components may be used (e.g. special cup, augment, reinforcement). The revision stem like the S-ROM is the most commonly used. Your surgeon will determine which of the four component’s design options will work best together to restore your accurate leg length, while minimizing the risks of post-operative dislocation and premature implant wear.
