PROBLEM TO BE SOLVED: To provide a spinous process fixator capable of easing pain of a patient by removing compression on a nerve and a vessel.SOLUTION: A spinous process fixator 10 comprises a support part 11 and a fixation wing part 12. At both opposed ends of the support part 11, a first support end surface 111 and a second support end surface 112 are formed, and the first and second support end surfaces 111 and 112 contact spinous processes S1 and S2 of two adjacent spines S and S'. The fixation wing part 12 is formed at a side edge of the support part 11 and many fixation holes 121 are installed on the fixation wing part 12. Bolts 13 after being respectively inserted into the fixation holes 121 are screwed onto the spines S and S' and are fixed, and then the fixation wing part covers a surgically-removed spinal section. Accordingly, since there is no need to screw the bolts onto the extremely-thin and fragile spinous processes, the fixator can effectively prevent the spinous processes from rupturing and can cover the surgically-removed spinal section with the fixation wing part 12. |
