Abstract

A spinal stabilization system includes vertebral engagement members and an intermediate structure. The vertebral engagement members are configured to be disposed between a first vertebra and a second vertebra. The vertebral engagement members generally include seating surfaces for accommodating at least a portion of a laminar region of adjacent vertebra and are adjustable between an operable and inoperable configuration. The intermediate structure extends between the vertebral engagement members. The structural cooperation of the vertebral engagement members and the intermediate structure is such that the engagement members distract the adjacent vertebrae.
