Analysis of the final follow-up data showed significant differences before and after surgery in the JOA score (t = 25.12, p<0.001), CI improvement (t = 22.68, p<0.001), the anteroposterior diameter at the level of maximum compression of the spinal cord (t = 9.67, p<0.001), and VAS score (t = 12.7, p<0.001).
