In addition to providing elastic force to the upper and lower spinous processes to maintain the space between the upper and lower spinous processes, the spinous processes are damaged by moving in fusion with the upper and lower spinous processes. This prevents the phenomenon of separation from between the spinous processes without causing them. The present invention relates to an interspinous process dynamic implant, comprising an upper plate that is in close contact with an upper spinous process, a lower plate that is in close contact with a lower spinous process, an anterior portion of the upper plate, and an anterior portion of the lower plate. An upper spinous process that is coupled between the upper plate and the lower plate by moving the spinous process so that the upper plate and the lower plate can move up and down and left and right within a predetermined range. Coupling means and lower spinous process coupling means for tightly coupling the lower plate to the lower spinous process.
