  • Patent number: 5405391
    Abstract: A fusion stabilization chamber stabilizes the spine following removal of one or more vertebrae, and facilitates bone growth. The chamber includes two hollow members, preferably having slightly trapezoidal cross-sections, which slide relative to each other in a telescoping manner. The hollow members preferably have walls made of a metal mesh. Barrel vaults attached to the hollow members form guides for screws which can attach the chamber to the vertebrae adjacent the corpectomy site. Because of its adjustability, the chamber can fit a wide variety of corpectomy sites. One can fill the chamber with bone material, which can eventually fuse to the adjacent bone. A pair of stabilizing plates prevents the surgeon from pushing the chamber too far towards the spinal cord. The chamber eliminates the need to maintain a large and costly inventory of screws, and neurosurgeons can learn to use it quickly and easily.
