Abstract: A spinal implant device having an anatomical shape designed to mimic and restore normal human spinal anatomy. The devices comes in a range of sizes and are structured to specifically accommodate the structure of at least one of the cervical, thoracic and lumbar regions of the spine. Once affixed to the vertebrae, the devices may be used to effectively fuse two or more vertebrae, or to stabilize the vertebrae and protect the posterior portions of the spinal cord. Adjustments for sagittal plane contouring may also be effected through cable tensioning via spinous process fixation.
