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.
