Abstract:
An interbody spinal fusion implant for fusion of two adjacent vertebrae in the human spine, comprising:a plurality of modular members, each of said modular members having a height substantially equal to the height of the space created by the removed disc material from between two adjacent vertebrae and a width substantially less than the transverse width of the vertebrae, each of said modular members comprising:an insertion end, a trailing end, opposed upper and lower portions adapted to be placed in contact with the end plates of the adjacent vertebrae, and side walls connecting said upper and lower portions, said upper and lower portions forming a support structure including at least a part of the surfaces of said upper and lower portions between said side walls for bearing against the end plates of the adjacent vertebrae, said upper and lower portions being disposed at least in part in a converging angular relationship along a longitudinal axis between said insertion and trailing ends to induce angulation of the adjacent vertebrae, said side walls of each of said modular members adapted to be positioned beside and in contact with at least another of said modular members in a side to side orientation within the space created between the adjacent vertebrae,whereby said plurality of modular members placed together form said spinal implant.
