Cortical and cancellous allograft spacer

A sterile composite graft comprising:

• a cancellous bone component member and a monolithic load bearing component member matable with said cancellous component member, said cancellous bone component member defining a planar front surface and a planar rear surface with a channel extending between said planar front and rear surfaces into the interior of the cancellous bone component member, said monolithic load bearing component member having a modified I beam construction with a front portion, a cross bar secured to a rear surface of said front portion and a planar inner surface of a rear portion, said cross bar being configured to fit into said channel holding said component members together in a mated relationship.

A sterile composite graft comprising:

• a cancellous bone component member and a monolithic cortical bone component member having spaced front and rear portions which are connected by a support bar, said cancellous bone component member having a trapezoidal shape and a channel cut into the interior of the cancellous bone component member, said cortical bone component member front portion defining a flat rear wall surface which abuts said cancellous bone component member, an integral support bar extending from said flat surface of said front portion to a rear portion defining a flat inner surface which also abuts said cancellous bone component member, said integral support bar being configured to fit into said channel holding said cancellous and cortical bone component members together.

A sterile composite bone graft for use in implants comprising:

• a monolithic load bearing member constructed of allograft cortical bone having a front portion with a rear planar surface and a rear portion with an inner planar face interconnected by a support bar extending between said planar surfaces to connect said front and rear portions, an allograft cancellous member defining inwardly tapered side walls, a flat proximal end surface and a flat distal end surface and an open channel cut into said cancellous member extending from said proximal end surface to said distal end surface configured to receive said support bar, said monolithic load bearing member and cancellous member being mated together with said support bar being mounted in said cancellous member channel, said front portion and rear portion of said cortical bone member having a height which is at least equal to a height of said cancellous member when the same is mated to said cortical member with the rear portion of said load bearing member having a smaller cross sectional area than the front portion.

A sterile composite graft comprising:

• a cancellous bone component member and a monolithic cortical bone component member with an I-beam configuration, said cancellous bone component member having a trapezoidal shape and a channel cut into the interior of the cancellous bone component, said monolithic cortical bone component member defining a flat inner surface which abuts said cancellous bone component member, a connected support bar extending from said flat surface to a rear section defining a flat inner surface which also abuts said cancellous bone component member, said support bar being configured to fit into said channel holding said cancellous and cortical bone component members together.

A sterile composite bone graft for use in implants comprising:

• a monolithic load bearing member with an I-beam configuration constructed of allograft cortical bone defining a front portion with a rear planar surface, a support bar extending from said rear planar surface to connect with a planar inner surface of a rear portion, an allograft cancellous member defining inwardly tapered side walls, a flat proximal end surface and a flat distal end surface and a channel cut into said cancellous member extending from said proximal end surface to said distal end surface, said load bearing member and cancellous member being mated together with said support bar being mounted in said cancellous member channel, said front portion and rear portion of said load bearing member having a height which is at least equal to a height of said cancellous member when the cancellous member is mated to said load bearing member.
