Abstract

Spinal stabilization mechanisms act to prevent lateral bending, extension, and rotation at the disc space. Two or more anchors at each vertebral level, and links at each level to both anchors at the other level result in a cross-braced arrangement that enhances compression and promotes fusion. In the preferred embodiment, the mechanism uses screws for placement in the vertebral bodies and cables are used to connect the screws. The cables pull the screws together, applying compression across the disc space. Bone graft, cages, or distracting plugs and the device to enhance fusion area would fill or cross the disc space. The bone graft, cages, etc. within the disc space are preferably used to resist compression. The device may be used in the cervical, thoracic, or lumbar spine. The device is preferably placed anteriorly, but could also be used posteriorly, with the screws directed through the vertebral body pedicles. The various components may be constructed of titanium, stainless steel, polymers, or a combination of such materials. The anchors preferably include a post protruding from the vertebra, and a cable-holders which fits over the post. The post may be threaded, in which case a nut would be used to tighten the holders, or the cable holders may be allowed to rotate, depending upon the position and/or application of the fasteners. The cable holders may use tunnels, tubes or outer grooves to the hold the cables in position. Devices may also be added to keep the links from crossing one another where they cross.

Independent Claims | See all claims (21)

  1. 1. Apparatus for stabilizing upper and lower spinal vertebra, comprising: a first pair of right and left fasteners attachable to the upper vertebra; a second pair of right and left fasteners attachable to the lower vertebra; a first cable interconnecting the right fasteners; a second cable interconnecting the left fasteners; a third cable interconnecting the right fastener of the first pair with the left fastener of the second pair; and a fourth cable interconnecting the left fastener of the upper vertebra with the right fastener of the second pair.
  2. 17. Apparatus for stabilizing spinal vertebra at two levels, comprising: a first pair of anchors positioned side by side on a first level of said two levels and a second pair of anchors positioned side by side on a second level of said two levels threaded end penetrable into the vertebra, and a post which remains exposed; at least one cable holder on each post; and at least one cable from each holder on each level to the two holders of the other level.
