What is it? TheNOVATION™ Ceramic Articulation Hip System is an alumina ceramic artificial hip replacement system, surgically implanted to completely replace a diseased or damaged hip joint.

For a picture of a hip implant, go to: http://www.fda.gov/oc/opacom/kids/html/total_hip.htm.

How does it work? The system has four parts that that work together to allow the hip joint to move:

• A metal hip stem, which 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 NOVATION™ Ceramic Articulation Hip System is indicated for use in primary total hip arthroplasty in skeletally mature patients with non-inflammatory degenerative joint disease such as osteoarthritis, avascular necrosis, congenital hip dysplasia, and traumatic arthritis.

What will it accomplish? The NOVATION™ Ceramic Articulation Hip System will reduce pain by replacing the painful arthritic hip joint, and restore its ability to move.

When should it not be used? The NOVATION™ Ceramic Articulation Hip System should not be used in patients who have any of the following:

• Active or latent infection in or around the hip joint;
• Acute or chronic systemic infections;
• Skeletally immaturity;
• Neurological or muscular conditions (e.g., prior paralysis, fusion and/or inadequate abductor strength) that could result in instability or overloading of the hip joint;
• Poor skin coverage around hip joint;
• Inadequate bone stock to allow proper insertion and fixation of the prosthesis;
• Metabolic bone disease and osteoporosis;
• Known allergies to the implant materials; and
• Obesity where obesity is defined as a Body Mass Index (BMI) greater than 35 .
