[INDENT]Welcome to the Healthboards for Back Problems. I had a 2 level lumbar fusion with Infuse on June 30, 2003. The FDA has approved Infuse only to be used with cages. My surgery was done without cages and my surgeon had used disc spacers instead. Therefore my surgery is experimental and not FDA approved and could be the reason why I have complication's. My surgeon did explain this to me prior to my surgery and told me that he had done this on other patient's with good outcomes. Your surgeon is most likely planning on uses the cages so here is a little information on the INFUSE.
INFUSE Bone Graft contains recombinant human bone morphogenetic protein (rhBMP-2), the genetically engineered version of a naturally occurring protein that is capable of initiating bone growth, or bone regeneration, in specific, targeted areas in the spine. Approved for use with the LT-CAGE Lumbar Tapered Fusion Device, INFUSE Bone Graft is indicated to treat certain types of spinal degenerative disc disease, a common cause of low back pain. Using INFUSE Bone Graft with the LT-CAGE Device in spine surgery reduces the pain and complications associated with treating degenerative disc disease by eliminating the second surgery required to harvest bone from a patient's hip, as is done in traditional spinal fusion procedures.
Spinal fusions essentially "weld" two or more vertebrae together to eliminate the pain caused by a damaged disc in the spine. To fuse the vertebrae together, surgeons traditionally insert pieces of the patient's own bone between the vertebrae to prompt the body to grow new bone. But implanting the bone chips actually requires two surgeries -- one to chip off small pieces of bone from around the patient's hip (autograft) and another to insert them in the spine. Studies have shown that the bone harvesting procedure can be more painful than the fusion itself, and nearly a third of patients experience some hip pain two years following surgery.
INFUSE Bone Graft eliminates the painful harvesting surgery because it contains rhBMP-2, which induces the body to grow its own bone where it is needed.
To use INFUSE Bone Graft, surgeons reconstitute the rhBMP-2 powder with supplied sterile water and then apply it to collagen sponges. The sponges are inserted inside each of two LT-CAGE Lumbar Tapered Fusion Devices, which are then implanted between the vertebrae. The thimble-like cages stabilize the spine while it is fusing and also maintain the proper height between the vertebrae. The tapered design of the cage is intended to help restore the natural curvature (lordosis) between vertebrae in the spine, as compared to traditional cylindrical cages.[/INDENT]
