Abstract
An intervertebral stabilization system for at least three vertebrae comprising pedicle screws attachable to the vertebrae; at least one rod for the connection of at least two pedicle screws to form a rigid stiffening system; and at least one band which is capable of being pre-stressed in tension and which is surrounded in the implanted state of the stabilization system by at least one compressible pressure member arranged between two adjacent pedicle screws for the connection of the pedicle screws to form an elastic support system, wherein a common pedicle screw is associated both with the stiffening system and with the support system and the band can be connected or is connected to the rod by means of a band attachment.
Claims22
An intervertebral stabilization system comprising:
- a first vertebral fastener configured to be secured to a first vertebra;
- a second vertebral fastener configured to be secured to a second vertebra;
- a third vertebral fastener configured to be secured to a third vertebra;
- a rigid member extending continuously from the first vertebral fastener to the second vertebral fastener and secured to each of the first vertebral fastener and the second vertebral fastener, the rigid member configured to provide rigid support between the first vertebra and the second vertebra of a spinal column, the rigid member including an end region having an opening extending therein, wherein the end region of the rigid member includes a first flange positionable on a first side of the second vertebral fastener and a second flange positionable on a second side of the second vertebral fastener, wherein the first and second flanges are integral with the rigid member;
- an elastic support system positioned between the second vertebral fastener and the third vertebral fastener, the elastic support system configured to provide dynamic support between the second vertebra and the third vertebra of the spinal column including a spacer and a flexible member sized to insert into the spacer;
- and
- a clamping member;
- wherein an end portion of the flexible member extends into the opening of the rigid member and is clamped in the opening of the rigid member with the clamping member.
