Spinal stabilization system and method

Abstract

A spinal stabilization system may include a pair of structural members coupled to at least a portion of a human vertebra with connectors. Connectors may couple structural members to spinous processes. Some embodiments of a spinal stabilization system may include fasteners that couple structural members to vertebrae. In some embodiments, a spinal stabilization system provides three points of fixation for a single vertebral level. A fastener may fixate a facet joint between adjacent vertebrae and couple a stabilization structural member to a vertebra. Connectors may couple the structural members to the spinous processes of the vertebrae. Use of a spinal stabilization system may improve the stability of a weakened or damaged portion of a spine. When used in conjunction with an implant or other device, the spinal stabilization system may immobilize vertebrae and allow for fusion of the implant or other device with vertebrae.

Description

PRIORITY CLAIM[0001] This application claims priority to U.S. Provisional Application No. 60 / 306,765 entitled "Spinal Stabilization System and Method," filed Jul. 20, 2001. The above-referenced provisional application is incorporated by reference as if fully set forth herein.[0002] 1. Field of the Invention[0003] The present invention generally relates to the field of medical devices, and more particularly to a system for stabilizing a portion of a spinal column. In an embodiment, the system joins together adjacent spinous processes to stabilize a portion of a spine.[0004] 2. Description of Related Art[0005] Spinal instability may result from many factors including trauma or degenerative disorders stemming from injuries and / or aging. In some instances, the effects of spinal instability may result in pain and / or partial or complete loss of mobility.[0006] Several devices and techniques have been developed to restore stability to the spine. For example, interbody devices may be implan...

AI Technical Summary

Problems solved by technology

In some instances, the effects of spinal instability may result in pain and / or partial or complete loss of mobility.

In some instances, interbody devices alone may not be capable of supporting a portion of a spine sufficiently to promote vertebral fusion.

In addition, pedicle screw insertion may require highly invasive surgery.

Such surgery may result in extended recovery times or even irreparable damage to adjacent tissues.

A spinal stabilization system may be adapted to stabilize a portion of a spine where a spinous process is not present, has been damaged or removed, or is not capable of withstanding structural loads for spinal fixation.
