- a plurality of fixing protrusions 25 are formed to be coupled to the sp2).
- the upper and lower, left and right movements of the adjacent spinous process can be moved together, so that the movement of the upper spinous process and the lower spinous process is much more natural than the conventional implants, and therefore, there is no effect on the spine.
- the plurality of spikes provided on the wing sticks to both sides of the spinous process so that the upper and lower wings are stably coupled to the upper and lower spinous processes.
- the upper wing and the lower wing can be inserted between the spinous process in the folded state, so that the wing is not caught in the upper and lower spinous process during insertion, there is an effect that can be inserted from the side as well as behind the spinous process.
