What is it? The Encore Keramos™ Ceramic/Ceramic Total Hip System is an alumina ceramic artificial hip replacement system, surgically implanted to completely replace a diseased hip joint.
How does it work? The system has four parts that work together to allow the hip joint to move:
- A metal hip stem, that a doctor places into a hole drilled in the end of the thigh bone,
- A ceramic, ball-shaped part (femoral head) that fastens to the metal hip stem,
- A ceramic, socket-shaped part (acetabulum) that the ball-shaped part fits in, and
- A metal shell that fastens the ceramic socket-shaped part to the hip bone.
The ceramic ball slides around in the ceramic socket, which allows this artificial hip joint to move.
When is it used? The Keramos™ Ceramic/Ceramic Total Hip System is for patients who need a total hip replacement because of painful inflammatory or non-inflammatory arthritis. Examples of inflammatory arthritis are:
- swelling, and
- gradual degeneration of tissues surrounding the joint.
Examples of non-inflammatory arthritis are:
- wearing out of the joint due to age,
- lack of blood flow to the bone, or
- joint damage due to injury.
What will it accomplish? The Keramos™ Ceramic/Ceramic Total Hip System relieves pain and allows for increased function in the hip.
When should it not be used? The Keramos™ Ceramic/Ceramic Total Hip System should not be used in patients who have:
- an infection in or near the hip joint,
- bones that are still growing,
- neurological disorders which might prevent the patient from following instructions during postoperative care,
- diseased or infected bones that cannot support or fasten to the prosthesis, or
- bones damaged by an earlier implant that cannot support or fasten to the prosthesis.
