Abstract
Methods and devices are provided for repairing or replacing damaged, injured, diseased, or otherwise unhealthy posterior elements, such as the facet joints, the lamina, the posterior ligaments, and/or other features of a patient's spinal column. In one exemplary embodiment, an implant is provided having an anterior portion that is adapted to be positioned between adjacent vertebrae and a posterior portion that is adapted to be positioned around a spinal cord and to couple to a posterior surface of at least one adjacent vertebra. In use, the implant can allow the adjacent vertebrae to move relative to one another, thereby restoring normal function to the vertebrae.
Claims11
A spinal implant, comprising:
- a substantially C-shaped member having an anterior portion adapted to be positioned between adjacent vertebrae and a posterior portion adapted to be positioned around a spinal cord and to couple to a posterior surface of at least one adjacent vertebra, wherein the posterior portion of the C-shaped member includes at least one extension member extending therefrom and adapted to mate to a posterior surface of a vertebra, the at least one extension member comprising first and second superior extension members extending in a superior direction from opposed lateral sides of the posterior portion of the C-shaped member, and first and second inferior extension members extending in an inferior direction from opposed lateral sides of the posterior portion of the C-shaped member.
A spinal implant, comprising:
- a substantially C-shaped member having an anterior portion adapted to be positioned between adjacent vertebrae and a posterior portion adapted to be positioned around a spinal cord and to couple to a posterior surface of at least one adjacent vertebra, wherein the posterior portion of the C-shaped member includes at least one extension member extending therefrom, adapted to mate to a posterior surface of a vertebra, and including a thru-bore formed therein for receiving a fastening element adapted to engage bone.
A spinal implant, comprising:
- a substantially C-shaped member having an anterior portion adapted to be positioned between adjacent vertebrae and a posterior portion adapted to be positioned around a spinal cord and to couple to a posterior surface of at least one adjacent vertebra, wherein the C-shaped member comprises a substantially C-shaped superior member, a substantially C-shaped inferior member, and at least one central member disposed therebetween, the at least one central member comprising first and second central members disposed between the anterior portion of the superior and inferior members, and third and fourth central members disposed between the posterior portion of the superior and inferior members.
