Abstract:
An implant for promoting bone fusion between adjacent vertebral bodies, said implant having an exterior surface, a longitudinal axis and comprising an assembly of cortical bone-derived components, said components comprising:a first strut having a first bone-engaging portion, an opposite second bone-engaging portion, a first impact surface disposed therebetween in a plane positioned substantially orthogonal to the longitudinal axis, and a first end opposite the first impact surface; a second strut spaced from said first strut, said second strut having a third bone-engaging portion, an opposite fourth bone-engaging portion, a second impact surface disposed therebetween in a plane positioned substantially orthogonal to the longitudinal axis, and a second end opposite the second impact surface, said second strut in cooperation with said first strut defining an internal space, wherein the first strut and the second strut each include an aperture opening into the internal space and wherein the first end of the first strut and the second end of the second strut each include a curved surfacing curving from the internal space to the external surface; an elongate cross-member extending from the first strut to the second strut and including a first end engaged within the first aperture of the first strut and a second end engaged within the aperture of the second strut; an osteogenic material interposed between the first and second strut, said osteogenic material provided to be adherent to at least one of the first strut, the second strut and the cross-member and adapted to be moldable to provide a semi-rigid shaped component; and wherein said first and second impact surfaces define planar surfaces positioned substantially parallel to the elongate cross-member and each planar surface comprising a tool engaging aperture.
