1. A spinal bone graft for implantation into a host, the spinal bone graft comprising:
one or more cortical bone portions forming a first unit, the first unit comprising a first bone engagement surface for contacting a bone of the host, and a first mating surface opposite the first bone engagement surface, the first mating surface forming at least one first undercut; and
one or more cortical bone portions forming a second unit, the second unit comprising a second bone engagement surface for contacting a bone of the host, and a second mating surface opposite the second bone engagement surface, the second unit comprising at least one connector;
the at least one connector having a cross section, the cross section comprising a first end comprising one or more lateral projections;
the at least one first undercut having a cross section configured to mate with the cross section of the at least one connector to receive the first end of the at least one connector in an interlocking fit, to interconnect the first unit and the second unit together,
wherein the at least one connector has at least one end face that is recessed inside a socket, forming an indent for engagement with a surgical instrument or clamping element, and
wherein at least one of the first unit and the second unit has a textured surface on the first bone engagement surface and the second bone engagement surface configured to promote bone ingrowth.
