Abstract: An instrument for the positioning of an implant into the human spine, as a replacement for one or more diseased vertebra bodies has vertebra body plates attachable to the healthy vertebra bodies. Distraction rods are provided which at one end are attachable to a vertebra body plate. Two U-shaped parts having limbs which telescopically cooperate and form a tubular housing around the attached distraction rods. The U-shaped parts comprise inner sections which are supported on the distraction rods. A distraction instrument which is connectable to the other ends of the distraction rods is used for exerting a force onto the rods transversely to their longitudinal direction.

Abstract: A spinal cage assembly has an inner sleeve-shaped tubular body which telescopes into or through an outer tubular sleeve-shaped body from either a first or second end thereof. Each inner and outer sleeve is made of one-piece construction made of a physiologically compatible metal. Both sleeve-shaped bodies have multiple holes therein and can be secured at different heights relative to one another. At least one of the sleeve-shaped bodies has two edges which form a different angle of between about 3° and about 6° with respect to the transverse axis of the sleeve-shaped bodies. An edge having a different angle is exposed depending on which end of the inner body is inserted into or through the outer body.

Abstract: A reconstruction system for vertebra, with at least one annular middle body and two annular end bodies. The end surfaces of the middle body and of the end bodies are formed such that the bodies may be stacked over one another and one end surface of the end bodies comprises a receiving section. The system includes two approximately right-angled vertebra body plates having a pair of limbs. One limb is formed such that in a direction perpendicular to the axis of an end body, it is insertable into the receiving section in a manner such that the one limb is prevented from moving away from the end body in the direction of the axis. The other limb comprises at least one bore for a bone screw and at least one threaded bore. A connection plate is provided, which at the ends comprises openings for connection to the other limb of each vertebra body plate via a screw.

Abstract: A means for the interconnection of two spaced elongated rods of a human spine implant, comprising a hook having a mouth and being adapted to partially grip around a first elongated rod, a transverse bar connected to the hook and gripping means adapted to be connected to the second elongated rod and to be attached to the transverse bar, whereby transverse bar and hook arm interconnected through a joint, the joint having joint portions which are adapted to be pivoted between a release position and a locking position, in that further locking means are provided which inhibit a pivoting of the joint portions of the hook to the release position and in that the joint portion connected to the transverse bar is structured such that in the release position the hook with its mouth can be freely placed onto the elongated rod while in the locking position the rod is locked within the mouth.

In another embodiment, one end of the hollow body comprises a means for turning the body by use of a tool.

Abstract: The invention relates to a connecting element for connecting a screw in the spine with a stabilizing rod, the connecting element being easily and quickly securable. The connecting element includes a receiving section which receives the stabilizing rod and which is part of a tension member having a threaded shank. A sleeve is arranged around the receiving section and can slide parallel to the shank axis. In the wall of the sleeve, two openings are present for positioning the rod. The connecting element further includes a nut which can be screwed onto the shank in order to fix the head of the pedicle screw at the sleeve. This connecting element has the advantage that by a single securing process (i.e., the tightening of the nut) the rod can be fixed in the receptacle of the tension member and the connecting element can be secured at the screw head.

Abstract: A device for stabilizing a long bone combines an external fixator with a locking nail implanted in the medullary canal of a long bone. The external fixator has fixed bone pins at each of its ends and movable bone pins intermediate its ends. The fixed bone pins extend through transverse bores at each end of the bone nail and the movable pins extends through a slot in the bone nail intermediate its ends. By this method a fracture can be compressed and stabilized while healing.
