Clinical Analysis Of Percutaneous Curved Angle Vertebroplasty For Thoracolumbar Osteoporotic Vertebral Compression Fracture

Objective:To compare the clinical efficacy of percutaneous curved Angle vertebroplasty(PCVP)and percutaneous vertebroplasty(PVP)in the treatment of thoracolumbar osteoporotic vertebral compression fractures.Methods:In this study,we grouped 90 fresh thoracolumbar OVCF patients who underwent surgery between September 2020 and December 2021.We divided these cases into PCVP group and PVP group for further discussion.Operation time,bone cement injection amount,intraoperative fluoroscopy times and operation cost were compared between the two groups.VAS scores and ODI values of the two groups were compared before surgery,2 days and 3 months after surgery.The incidence of common complications(bone cement leakage + chronic pain + refracture of the affected vertebra and adjacent vertebra)was compared between the two groups after six-month follow-up.Results:After comparison,the surgical cost and intraoperative bone cement injection amount in the two groups were higher than those in the PVP group(P < 0.05),but the intraoperative fluoroscopy times and operation time had no significant differences(P >0.05).In addition,there was no significant difference in preoperative ODI values(P >0.05).Comparing the ODI values between and within the groups,the ODI values at 2and 3 months after surgery were lower than those before surgery,and the change was statistically significant(P < 0.05).There was no significant difference in VAS scores between the two groups before surgery,2 days after surgery and 3 months after surgery(P > 0.05).The VAS values at 2 days and 3 months after surgery were lower than those before surgery,the difference was statistically significant(P < 0.05).However,there was no significant difference between PCVP and PVP in the incidence of bone cement leakage,chronic pain,and refracture of the affected and adjacent vertebral bodies(P >0.05).After a control study on the common complications(bone cement leakage +chronic pain + refracture of the affected vertebral body and adjacent vertebral body)between the two groups,the results showed that the complication rate in the PCVP group was lower than that in the PVP group,and there was a significant difference between the two groups(P < 0.05).Conclusion:Percutaneous curvature vertebroplasty(PCVP)increases the amount of bone cement injected in the treatment of thoracolumbar osteoporotic vertebral compression fractures,which may lead to better cement diffusion and reduce the incidence of common complications during postoperative follow-up(cement leakage + chronic pain +re-fracture of the affected and adjacent vertebral bodies).In terms of acute pain relief,Both PCVP and PVP have good clinical effect,but the operation cost of PCVP is high.
