Cages have been used since 1992 to help fuse vertebra. Interbody cage fusion uses a hollow threaded titanium or carbon fiber cylinder to fuse two vertebrae together. The diseased disk is removed and two interbody cages are placed in the opening where the diseased disk has been removed. The cages are filled with bone graft. The bone grows through the holes in the cages fusing the vertebrae. How does it work? The fusion cage component maintains the spacing and temporarily stabilizes the diseased region of the spine, while the InFUSE™ Bone Graft component is used to form bone which would permanently stabilize (fuse) this portion of the spine. When is it used? The device is used to treat degenerative disc disease. What will it accomplish? A clinical study showed that the use of this device was as safe and effective in promoting spinal fusion as the same fusion cage component filled with autograft bone.
