Interspinous dynamic stabilization implant and method of implanting

Abstract

Devices and methods for treating spinal disorders and associated discomfort therefrom. In one embodiment, an interspinous implant device is configured for distracting an adjacent pair of spinous processes while permitting relative flexion, lateral bending and side rotation motions between the vertebrae joined to the adjacent pair of spinous processes. A method of treating spinal disorders and associated discomfort therefrom, includes inserting an interspinous device between a pair of adjacent spinous processes such that a superior portion of the device contacts an inferior surface of the relatively superior spinous process of the pair, and an inferior portion of the of the device contacts a superior surface of the relatively inferior spinous process of the pair; and distracting the superior and inferior portions, relative to one another, thereby distracting the spinous processes, whereby vertebrae integral with the spinous processes retain capability of flexion, lateral bending and side rotation motions, relative to one another, after the distraction has been performed.
