摘要:
An apparatus and method is provided to maintain vertebrae in a desired relationship. The apparatus includes a rod, a plurality of clamps, and a plurality of fastener assemblies. The method involves inserting threaded members into openings in a displaced vertebra and at least one vertebra on each side of the displaced vertebra. A clamp is placed on each fastener. The rod is bent to correspond to a desired spinal curvature and inserted into the clamps. A nut is tightened on each threaded member to hold the clamp to each vertebra and to press the clamp against the rod to hold the rod against axial and rotational movement.
