SPINOUS PROCESS IMPLANT WITH GEAR TEETH

Devices and methods for spinous process implants with two plates that are connected together by a post, with each plate configured to be positioned on outer lateral sides of spinous processes with the post extending through the interspinous space. The second of the two plates includes a bore that receives the post, and that plate is movable along the length of the post to accommodate different anatomies, and selectively lockable in position. The post includes external gear teeth. A tool with a drive gear is used to releasably gearingly engage the gear teeth of the post and drive the second plate toward the first plate. When the plates are in their desired locations, the second plate is locked in position and the surgical tool may be removed.
