Problems solved by technology

However, for the vertebral connection method, the medical community is increasingly concerned that the rigidity of the biomimetic mechanism between the vertebrae will quickly damage the active segment of the adjacent vertebrae.
More specifically, unlike natural intervertebral discs, the vertebrae impede the relative pivoting and rotation of the connected vertebrae
This lack of mobility increases the stress on the moving segments of adjacent vertebrae

Embodiment Construction

[0074] In order to facilitate understanding of the principles of the present invention, the embodiments or examples in the drawings will now be referred to and explained. It should be understood, however, that no limitation of the scope of the invention is intended herein. Any replacement or further modification of the illustrated embodiments, as well as further application of the principles of the present invention, are normal for those skilled in the art to which the present invention relates. Individual features between different embodiments may be combined to form other embodiments. In addition, deformities such as spondylolisthesis are discussed here; however, the various prosthetic devices described herein can be used not only with vertebrae that are misaligned, but also with vertebrae that are substantially aligned.

[0075] 1. Lateral correction

[0076] In many deformities, such as spondylolisthesis, one or more vertebrae are offset relative to other vertebrae or th...

Abstract

A prosthetic device for lateral insertion into an intervertebral space is provided. The prosthetic device includes a first component having a first laterally-extending flange for engaging a first vertebra from a lateral approach to the first vertebra, the first component having a first articular surface. The prosthetic device further includes a second component having a second laterally-extending flange for engaging a second vertebra from a lateral approach to the second vertebra, the second component having a second articular surface for cooperating with the first articular surface to permit articulating motion between the first and second components.

Description

[0001] Cross References to Related Applications [0002] This application claims priority based on US Provisional Application No. 60 / 446,963, filed February 12, 2003. For good reason, US Provisional Application No. 60 / 446,963 is incorporated in this application. Background of the invention [0003] The present application relates generally to orthopedic and spinal surgery, and in some embodiments, the present application relates to intervertebral prosthetic joints and methods and tools for their use for total or partial replacement of natural intervertebral discs. [0004] In the treatment of disease injuries or deformities affecting the active segments of the spine, especially the intervertebral disc tissue, it has long been practiced to remove some or all of the degenerated, ruptured or damaged intervertebral discs. When disc tissue is removed or otherwise removed from the active portion of the spine, corrective measures are taken to ensure proper space between the vertebra...
