Medtronic's Bone Graft/LT-Cage lumbar tapered fusion device, bone graft replacement approved for use in Australia.

Medtronic, Inc., Minneapolis, MN, announced the Australian Therapeutic Good Administration (TGA) has approved Infuse Bone Graft/LT-Cage, Inter Fix and Inter Fix RP devices for spinal fusion. The approval means Infuse Bone Graft will be available nationwide in Australia.

The company says the Infuse Bone Graft/LT-Cage Device was designed to aid in the treatment of degenerative disc disease. It consists of two parts - a small, hollow, threaded, tapered metal cylinder and a bone graft substitute. The device is intended to restore the degenerated disc space to its original height, relieving pressure on the nerves. Two of the cages are placed side-by-side during surgery.

Medtronic says the cages are filled with Infuse Bone Graft, which consists of recombinant human Bone Morphogenetic Protein 2 (RhBMP-2) and an absorbable collagen sponge. The protein is a genetically engineered version of a natural protein normally found in small quantities in the body. The company says the protein stimulates bone formation. During surgery the protein solution becomes soaked into the ACS. The ACS acts as a scaffold for the formation of new bone. Over time the ACS resorbs, or disappears, in the body.

Infuse Bone Graft is the only bone graft replacement to receive a US Pre-Market Approval from the FDA specifically for use in lumbar spinal fusion procedures to treat degenerative disc disease. Medtronic says Infuse Bone Graft can also make spinal fusion easier on patients by eliminating the traditional bone procurement from a patient's hip.
