Abstract
A fusion cage having a substantially continuous sidewall made from any of various materials including titanium, PEEK, a carbon graphite fiber, or even a combination of these materials. A hollow core defined by the sidewall is typically filled with bone graft in order to form a solid fusion with vertebrae. The sidewall of the cage has upper and lower surfaces, an anterior section, at least two lateral sections each connected to the anterior section, and a posterior section connected to the lateral sections. The sidewall is preferably tapered at one of either a four or eight degree incline from the posterior to the anterior section so as to maintain backbone curvature. A plurality of distinct tool ports provide for anterior, lateral and/or anterolateral insertion of the device. Each tool port is provided with screw insertion orifices.

11. A vertebral body fusion cage comprising:
-
a continuous sidewall having upper and lower surfaces, an anterior section, at least two lateral sections each connected to the anterior section, and a posterior section connected to each of the at least two lateral sections; a first insertion tool port positioned within the anterior section of the sidewall; at least one additional insertion tool port positioned within one of either a lateral section of the sidewall or between the first insertion tool port and either lateral section of the sidewall; and a porous coating applied to each of the upper and lower surfaces of the continuous sidewall to promote adhesion;
wherein the sidewall tapers at an angle from the anterior section to the posterior section. - View Dependent Claims (12, 13, 14, 15, 16, 17)
