Abstract
A novel system and method for use for ensuring appropriate positioning of a cable about bone portions, particularly, vertebral bone, for stabilization of the spine during spinal reconstructive and fusion procedures is disclosed. The system includes cabling uniquely adapted for spinal reconstruction processes, ligature passers and hook passers of varying sizes to facilitate looping of the cable about the spinal/vertebral bone, and a tensioning apparatus which secures the cable at a predetermined tensioned value about the vertebral bone. A novel method for applying a cable about vertebral bone for spinal stabilization is also disclosed.
Claims6
A tensioning apparatus for applying a predetermined level of tension to a cable looped about tissue portions, which comprises:
- a handle;
- an elongated member extending from the handle and defining a longitudinal axis;
- first and second cable engaging pawls mounted to the elongated member for releasably engaging respective ends of the cable;
- a movable grip mounted to the handle;
- and
- an actuating member connected to the movable grip and adapted to longitudinally translate upon movement of the movable grip, the actuating member operatively connected to the cable engaging pawls whereby movement of the movable grip causes corresponding movement of the cable engaging pawls to tension the cable.
