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 first bone of the host, and a first mating surface opposite the first bone engagement surface, the first unit defining a first undercut extending from a first opening defined in the first mating surface;
one or more cortical bone portions forming a second unit, the second unit comprising a second bone engagement surface for contacting a second bone of the host, and a second mating surface opposite the second bone engagement surface, the second unit defining a second undercut extending from a second opening defined in the second mating surface, and
a connector having a first portion configured to be received within the first undercut and a second portion configured to be received within the second undercut such that the first unit and the second unit are coupled to each other via the connector and such that the first mating surface and the second mating surface face each other and are separated to define a void therebetween for receipt of a cellular bone matrix between the first mating surface and the second mating surface,
the first portion of the connector having a shape configured to be received within the first undercut such that, when disposed within the first undercut, the first portion is obstructed from passing through the first opening defined in the first mating surface by portions of the first unit defining the first undercut.
