ABSTRACT:
A method for facilitating fusion of bone structures includes providing an implant member for positioning between opposed bone structures, the implant member having a first end and a second end, and a segmentable portion having an outer wall defining an internal cavity for reception of bone growth inducing substances. The outer wall has at least one groove which extends substantially continuously about the outer wall to define a plurality of discrete ring-like segments. Each ring-like segment includes a plurality of apertures extending therethrough in communication with the internal cavity to permit fusion of vertebral bone tissue. The vertebral space defined between adjacent vertebral bodies is accessed, and the desired implant member length for insertion into the space between adjacent vertebral bodies is determined. The implant member is cut to the desired length and advanced within the vertebral space between the adjacent vertebral bodies.
