Abstract
This invention is an implantable device for dynamic stabilization of the spine that allows desirable spinal movement and prevents undesirable spinal movement. The device comprises: a longitudinal sequence of incompressible segments; a plurality of substantially-inelastic members that connect the segments through non-central channels; and a plurality of motion-dampening members. Desirable movement includes naturally-dampened flexion, extension, lateral bending, and torsion of the spine within a normal range of motion. Desirable movement may also include gradual correction of abnormal spinal curvature. Preventing undesirable movement includes preventing movement of the spine outside its normal range of motion. Preventing undesirable movement may also include alleviating intervertebral disc compression by providing vertebral support.
