Embodiment Construction

[0059] For the purposes of promoting an understanding of the principles of the invention, reference will be made to the embodiments illustrated in the drawings, and specific language will be used to describe the same. It should be understood in any case that no limitation of the scope of the invention is intended here. Any similar changes and modifications of the illustrated devices and any similar applications of the principles of the invention described are deemed to be within the ordinary skill of those skilled in the art to which the invention pertains.

[0060] The present invention includes a triangular fixed plate. In one application, the fixation plate is placed in the space available between the left iliac vein and the right iliac artery. In this way the fixation plate is suitable for eliminating disturbances to the tissue of the implantation site. The triangular shape allows the fixation plate to have a greater effective area while minimizing its risk of contacting...

Abstract

Systems and methods for stabilizing the spine are provided. For stabilizing the L5-S1 junction, the system includes a plate that has a generally triangular shape with an upper node and a pair of lower nodes. The upper node has a hole through the plate to receive a screw for passage into the L5 vertebra. The lower nodes each include a hole through the plate to receive screws for passage into the S1 vertebra. The system further includes a plate having a retaining element for preventing backout of screws inserted through the plate. Instruments and methods for attaching the plate to the spinal column are also provided.
