Problems solved by technology

An intervertebral disc may be subject to degeneration caused by trauma, disease, and / or aging.
Partial or full removal of an intervertebral disc may destabilize a spinal column.
Excessive pressure applied to the nerves may cause pain and / or nerve damage.
Fastening systems may attach a spinal plate to vertebrae without allowing fasteners of the fastening systems to back out from the vertebrae.
In some embodiments, a spinal compression plate may compress longitudinally during use; however, the spinal compression plate may be inhibited from expanding longitudinally during use.

Embodiment Construction

[0061] A spinal plate system may be used to stabilize a portion of a spine. A spinal plate system may include a spinal compression plate and fasteners that couple the spinal compression plate to vertebrae. Components of a spinal plate system may include materials such as, but not limited to, stainless steel, titanium, titanium alloys, ceramics, and / or polymers. Some components of a spinal plate system may be made of materials that may be autoclaved and / or chemically sterilized. Some components of a spinal plate system may be formed of materials unable to be autoclaved and / or chemically sterilized. Components unable to be autoclaved and / or chemically sterilized may be made of sterile materials and placed in working relation to other sterile components during assembly of a spinal plate system.

[0062] Spinal plate systems may typically be used to correct problems in lumbar and cervical portions of a spine resulting from injury and / or disease. For example, a spinal plate system may be im...

Abstract

A spinal plate system that maintains intervertebral spacing and spinal stability is provided. In an embodiment, a spinal compression plate may include two or more plates coupled together form an adjustable-length plate. Compression of a spinal compression plate movement may mimic natural settling of bones in a spine and / or distribute at least a portion of a vertebral load to an implant positioned between two vertebrae. Maintaining at least a portion of the vertebral load on an insert may increase bone growth and increase fusion between an implant and surrounding vertebrae.

Description

PRIORITY CLAIM[0001] This application claims priority to Provisional Patent Application No. 60 / 353,272 entitled "SPINAL PLATE SYSTEM FOR STABILIZING A PORTION OF A SPINE" filed on Feb. 1, 2002.[0002] 1. Field of the Invention[0003] The present invention generally relates to bone fixation systems. An embodiment of the invention relates to a compression plate for a spinal fixation system. The compression plate may be installed using an anterior procedure. The compression plate may be used in conjunction with one or more spinal implants that fuse vertebrae together.[0004] 2. Description of Related Art[0005] An intervertebral disc may be subject to degeneration caused by trauma, disease, and / or aging. A degenerated intervertebral disc may have to be partially or fully removed from a spinal column. Partial or full removal of an intervertebral disc may destabilize a spinal column. Destabilization of a spinal column may alter a natural separation distance between adjacent vertebrae. Mainta...
