Retrospective Study Of Percutaneous Vertebral Augmentation For The Treatment Of Osteoporotic Vertebral Compression Fractures

Part Ⅰ Retrospective study of unipedicular and bipedicular approach to Percutaneous Vertebroplasty for the treatment of Osteoporotic Vertebral Compression FracturesObjective: To compare the clinical effect of PVP between unipedicular and bipedicular approach for patients with OVCF.Methods: 49 patients(49 vertebraes)with thoracolumbar OVCF were treated with PVP in the Third Affiliated Hospital of Guangzhou Medical University from July 2015 to December 2017.23 cases were treated by PVP via a unipedicular approach(unipedicular group)and 26 cases were treated by the bipedicnlar approach(bipedicular group).Statistical analysis was performed on the number of fluoroscopy of C-arm X-ray machine,the operation time,the postoperative hospital stays,the VAS scores and postoperative complications.Results: 49 patients were successfully completed operation,no serious complications were found in traoperative and postoperative.Both of the postoperative hospital stays and the bone cement leakage rate were no significant difference between the two groups cases(P > 0.05);there were a statistical significance of the operation time and the number of fluoroscopy of C-arm X-ray machine between the two groups(P<0.05).However,Both of the Preoperative and postoperative the VAS scores were no significant difference between the two groups cases(P > 0.05);but there were a statistical significance of the Preoperative and postoperative the VAS scores in each group cases(P<0.05).Conclusions: Unipedicular and bipedicular approach to PVP for the treatment of Osteoporotic Vertebral Compression Fractures can significantly reduce the pain of patients.However,the unipedicular group can shorten the operation time and reduce X-ray exposure.To compare the bipedicular group,It is a more valuable clinical choice.Part Ⅱ Retrospective study of bipedicular approach to Percutaneous Vertebroplasty and Percutaneous Kyphoplasty for the treatment of Osteoporotic Vertebral Compression FracturesObjective: To compare the clinical effect of bipedicular approach to PVP and PKP for patients with OVCF.Methods: 54 patients(54 vertebraes)with thoracolumbar OVCF were treated with PVP/PKP in the Third Affiliated Hospital of Guangzhou Medical University from July 2015 to January 2018.26 cases were treated by PVP(PVP group)and 28 cases were treated by PKP(PKP group).Statistical analysis was performed on the number of fluoroscopy of C-arm X-ray machine,the operation time,the cement volume,the postoperative hospital stays,the VAS scores,the preoperative and postoperative vertebral anterior height,the recovery of Cobb angle and postoperative complications.Results: 54 patients were successfully completed operation,no serious complications were found in traoperative and postoperative.The cement volume,the postoperative hospital stays,the bone cement leakage rate and the vertebral refracture rate were no statistical significance between the two groups cases(P > 0.05);there were a statistical significance of the operation time and the number of fluoroscopy of C-arm X-ray machine between the two groups(P<0.05).Both of the Preoperative and postoperative the VAS scores were no significant difference between the two groups cases(P > 0.05);but there were a statistical significance of the Preoperative and postoperative the VAS scores in each group cases(P<0.05);there were a statistical significance both the postoperative vertebral anterior height,the recovery of Cobb angle between the two groups and the postoperative vertebral body’s anterior height,the recovery situation of Cobb angle in each group cases(P<0.05).Conclusions: Bipedicular approach to PVP and PKP for the treatment of Osteoporotic Vertebral Compression Fractures can significantly reduce the pain of patients.However,PVP group can shorten the operation time and reduce X-ray exposure.However,PKP is superior to PVP in the recovery of the postoperative vertebral anterior height Cobb angle.
