| abstract |
The invention is directed toward a sterile composite bone graft for use in implants comprising an I beam cortical bone load bearing member upon which is mounted a trapezoidal shaped cancellous member. The allograft cancellous bone member defines tapered side walls, a flat proximal end wall and a flat distal end wall and a channel into the body leading from the front wall to the end wall. The I beam cortical member has a front section with a flat rear surface. A rectangular support bar extends from the flat rear surface to the flat rear wall of the rear section forming a connecting bar which fits into the channel cut into the cancellous member body. The I beam cortical member support bar and the channel of the cancellous member mate together to hold both component members in stable relationship. Pins may be mounted in both members on opposite sides of the members interface. |
