Compound bone structure fabricated from allograft tissue

摘要

A composite allograft bone device comprising a first bone member body defining with a face that includes a plurality of intersecting grooves cut into the face of the body to define a plurality of spaced projections forming a pattern and a second bone member body defining a face that includes a plurality of angularly intersecting grooves cut into the face to form a plurality of spaced projections forming a second pattern. The projections on the second face fit into grooves cut in the first face allowing the two bodies to be mated together with the spaced projections of each face fitting into the grooves of the opposing face. The mated bodies form a composite bone device which is provided with a throughgoing bore positioned at an angle to the longitudinal axis of the composite device and a dowel mounted in the throughgoing bore extending into the bone member bodies precluding the same from relative longitudinal movement.
