A prospective randomized cohort study.
The objective of this study was to investigate the effect of intraoperative vertebral anesthesia on osteoporotic vertebral compression fractures (OVCFs) when treated with percutaneous kyphoplasty (PKP).
Only a few studies have evaluated the intraoperative pain reducing strategies during PKP.
A total of 64 patients with OVCFs were enrolled in the study. All of the patients were randomized into 2 groups: the traditional local anesthesia group (from the skin to the periosteum, group A) and the experimental group (from the skin to a vertebral body, group B). Visual Analogue Scale (VAS) score was used to evaluate the degree of pain at six time points, that is, VAS before surgery, VAS during balloon dilation, VAS during bone cement injection, VAS soon after surgery, and VAS 12 hours and 24 hours after surgery. In addition, we noted the patients’ willingness to undergo reoperation if necessary, and the variations in surgical complications between the 2 groups.
There was no significant difference in VAS score before surgery between the 2 groups (t=1.694, P=0.095). The VAS scores during balloon dilatation, bone cement injection and soon after surgery were significantly different between the 2 groups (t=4.405, P=0.000; t=2.481, P=0.016; t=2.992, P=0.004, respectively). The willingness to undergo reoperation was significantly different between 2 groups (χ2=6.020, P=0.049), whereas the complications showed no significant difference (χ2=0.000, P=0.754).
Traditional local anesthesia combined with vertebral anesthesia was effective in alleviating perioperative pain during PKP. No serious complication was noted during the operation.
