Abstract:
A vertebrae linking system for restricting relative movement between adjacent vertebrae and promoting fusion of the adjacent vertebrae. The invention comprises a system for linking spinous processes of adjacent vertebrae of a vertebral column of a patient, including an elongate linking plate apparatus for extending between the spinous processes of the adjacent vertebrae. The plate has opposite ends, and a pair of securing apertures formed in the linking plate, each of the securing apertures being located toward one of the ends of the linking plate. Preferably, a pair of sets of securing apertures are located at each end of the linking plate, each set of securing apertures comprising at least two apertures. The system includes a method for restricting movement of adjacent vertebrae with respect each other in the vertebral column of a patient, which comprises forming passages through the spinous processes, aligning securing apertures with the passages, and passing a connecting member through the apertures and passages. The system also includes a method for facilitating fusion between spinous processes of adjacent vertebrae, including forming an interstice between opposing faces of first and second plates and the spinous processes of first and second vertebrae, and placing a bone material in the interstice.
