Abstract
Systems and method in accordance with embodiments of the present invention can includes an implant having a spacer with an expandable portion. An insert can be positioned within a groove of the spacer to distract the expandable portion away from the main portion of the spacer. The expandable portion can optionally include a grip that can at least partially deform to conform to a contour of a spinous process to provide a frictional grip to prevent the implant from shifting position. Implants in accordance with the present invention can also include a binder that can be arranged around the adjacent spinous processes to limit flexion movement.
