Abstract: The present invention is a surgical bone brush which provides a means to remove soft tissue from harvested autogenous and allografts bone prior to implantation of the bone into the human body. The invention is a surgical instrument with multiple fibers of surgical grade stainless steel or implantable material, wherein the fibers are held in place around a retaining ring, by a cap assembly, and extend outward forming a brush. The bone brush head, provided in a plurality of sizes and shapes, is attached at one end of a shaft, of a length and diameter providing for the insertion of the shaft into surgical grade rotary hand pieces. The bone brush provides a means to remove soft tissue from bone, decorticate, and contour bone. This is achieved when the shaft of the bone brush is inserted into a surgical rotary hand piece and the hand piece is activated thereby causing the brush head to rotate.

Abstract: An adjustable spinal fixator for insertion between adjacent vertebrae comprises a contoured housing defining convex edges to fit within the concavity of the vertebral body. An externally threaded core extends through the housing, and a pair of internally threaded nut assemblies attach to the core member. Four crown members with teeth are separately mounted within the housing and retract and variably extend with the movement of the movable nuts on the core member. Two of the crown members extend and retract from the top of the housing, and the remaining two crown members extend and retract from the bottom of the housing. The spinal fixator is positioned between adjacent vertebrae with the crown members retracted so that the teeth are below the convex edges of the housing. Following placement, the crown members are extended outwardly from the top and bottom of the housing by rotation of the core member which causes the teeth to penetrate the bone at an angle to secure the spinal fixator in position.
