Abstract: A sterile composite bone graft for use in implants comprising a T shaped cortical bone load bearing member mated to a cancellous member. The crosspiece of the T defines an inner planar surface and dove tail shaped mating member extends outward from the inner planar surface. The allograft cancellous bone member defines tapered side walls on the exterior surface of the body, a flat proximal end surface and a flat distal end surface. A dove tail shaped recess with the narrowest portion exiting the flat proximal end surface is cut into the interior of the cancellous member body. The dove tail shaped member and dove tail shaped recess are mated together to hold both component members together. Pins are mounted in both members to provide additional stability.

Abstract: The invention is directed toward a bone-tendon-bone assembly extended between two shaped cancellous bone blocks and a method of inserting same in a joint. Each substantially cylindrically shaped cancellous bone block has a central through going bore, a flat exterior longitudinal surface and a channel longitudinally cut in the exterior of the bone block body opposite the flat longitudinal surface. A tendon replacement member is inserted through the central through going bore around the end of each block and looped back along the flat longitudinal side with each block being in a reversed orientation position as to the other block. A channel cut in the exterior surface of each block is adapted to receive an interference screw to keep the block anchored in a bone tunnel previously cut in the respective bones of a joint.

Abstract: The cannula handle housing includes a recessed seat, wings extending outwardly from the recessed seat in the housing for engagement with a physician's hand and a stem which extends from said housing to hold a portion of a cannula The cannula has a distal sharpened end and a proximal end secured to a Luer lock. The stylet includes a longitudinal member having a sharp tip with the other end of the stylet formed with an anvil structure which is molded into a stylet cap. The stylet cap is a housing which includes a projection portion having a complimentary configuration to the recessed seat formed in said cannula housing for interlocking with the Luer lock of the cannula housing. The stylet inserts into the cannula and with a twist, locks about the Luer lock on the proximal end of the cannula.

Abstract: A composite allograft bone device having a first bone member body with a face that defines a plurality of spaced projections forming a pattern and a second bone member body defining a face that forms a plurality of spaced projections forming a second pattern. The projections in the first face allow the two bodies to be mated together. The mated bodies form a composite bone device which is provided with a throughgoing bore and a threaded rod member mounted in the throughgoing bore extending into and engaging the bone member bodies holding the same together. Alternatively a rod member with a demineralized or knurled outer surface can be press fit into the throughgoing bore engaging the bone member bodies in an interference fit holding the same together. In another embodiment an inner central cancellous bone block is surrounded by plates or a U shaped base constructed of cortical bone material.

Abstract: The invention is directed toward an osteoimplant for application to a bone defect site to promote new bone growth at the site which comprises a new bone growth inducing composition of demineralized allograft bone material mixed with an aqueous phosphate buffered gelatin which when lyophilized to remove water from the composition cross links the gelatin to form a solid structure.

Abstract: The bone marrow mixing instrument having a handle housing with a trigger mounted thereto. The handle housing contains a ratchet drive feed mechanism with a pawl assembly and a moveable ratchet bar. The other end of the ratchet bar is secured to a mixing housing which holds syringes filled with material and defines channels leading from the syringe area to a mixing nozzle removably mounted to the mixing housing. A piston rod and piston are mounted in each syringe containing bone defect material with a piston being advanced within the respective syringe by the feed mechanism to discharge bone defect material from the syringe into the adjacent channels in the mixing housing and into the mixing nozzle.

Abstract: The invention is directed toward a formable bone composition for application to a bone defect site to promote new bone growth at the site which comprises a new bone growth inducing compound of demineralized lyophilized allograft bone particles.
