Abstract

An apparatus and method for moving a vertebra to a desired relationship with other vertebrae and for maintaining the desired relationship. Mounting blocks are attached to the vertebrae.

The rod is rotated to move a vertebra relative to the other vertebrae. The mounting blocks are then tightened around the pivot members to maintain the vertebrae in the desired relationship.
