In the acetabular preparation, special mushroom-shaped reamers are used to get rid of the diseased and broken cartilage and bone. the world is power washed to get rid of all blood, fat and debris and totally dried. Once the bone is dry, cement is place in and pressure applied to force the cement into the honeycomb of the bone. Implants comprised of a metal shell and a liner are then inserted. generally the shell is fastened in place with two or three screws through into the hip bone.

For the femoral preparation, the femoral head is removed and ream the shaft out with specially formed rasps. the world is power washed to get rid of all blood, fat and debris and totally dried.

The main downside with the DePuy ASR is its defective style. The sub-hemispherical style of the acetabular part and also the low clearance between the cup and also the femoral head were speculated to enable for a larger vary of motion of a patient's hip. These 2 aspects of the look, however, have proven to be disastrous. The shallow cup doesn't offer for a sufficient arc of canopy for the femoral head, and consequently results in edge-loading, wear and unleash of huge amounts of metal debris. The metal particles, though tiny, are nice in variety, and also the immune system's defense mechanisms don't seem to be able to get rid of such a lot of foreign particles within the body. The debris will harm the muscle and tissue round the implant and should cause inflammatory responses in patients.

Depuy Orthopedics, a division of Johnson and Johnson, has issued a WORLDWIDE RECALL of it's "metal-on-metal" ASR XL Acetabular System for Total Hip Replacement.
