---|---|---|---|---|
Primary | First puncture success rate,number of insertions before reaching the desired position, number of fluoroscopy before reaching the desired position, radiation dosage before reaching the desired position, operation time before reaching the desired position | All the operations were successfully completed. The number of pedicles successfully first pierced in group C was higher than that in group A and group B (P<0.05);The number of insertion, fluoroscopy and operation time before the insertion needle reached the ideal position, the total number and time of intraoperative fluoroscopy, and the intraoperative blood loss in group C were all significantly lower than those of group A and group B (P<0.05) | twenty months | |
Primary | VAS scores after surgery | All patients were followed up 6 months after surgery. VAS scores at 1 day and 7 days after surgery were higher in Group A than those in other groups(P<0.05), but no differences were found VAS scores at 1 , 3 and 6 months after surgery in 3 groups.Specific methods: drawing a 10cm line on the paper, one end of the horizontal line is 0, that is painless; The other end is 10, which means severe pain; The intermediate part indicates different levels of pain. Asking the patient to mark the level of pain on a horizontal line according to how he or she feels. 0-2: meaning comfortable; 3-4: slight discomfort; 5-6: moderate discomfort; 7-8: Severe discomfort;9-10: Extreme discomfort. | twenty-two months |
