Abstract

The surgical instrumentation system is adapted to provide an operative approach to the spinal column and maintain distraction of adjacent vertebrae. The system includes at least one retractor and a pair of opposite distractor mechanisms mounted to a frame. The distractor mechanisms each include an adjustment mechanism permitting the distractor mechanism to be pivoted relative to the vertebra and secured to the frame after being repositioned.
