Patent ID: 8343229

Claim:
An implantable bone block, comprising: a solid block of cortical bone characterized by a length (along an x-axis), width (along a y-axis) and thickness (along a z-axis), having a first face and a second face along the x and y axes on opposite sides of the block, each of the first and second faces having a plurality of substantially linear and substantially parallel slot features wherein the angle of incidence (a 1 ) of the slot features of the first face and the x-axis and the angle of incidence (a 2 ) of the slot features of the second face and the x-axis are such that the slot features of the first face would intersect the slot features of the second face if they were in the same plane, wherein the slot features are characterized by a depth substantially along the z-axis, wherein the sum of depth (d 1 ) of the features on the first face and the depth (d 2 ) of the features on the second face is greater than the thickness of the block.
