Comparison of unilateral and bilateral percutaneous vertebroplasty in the treatment of severe vertebral compression fractures

Abstract

BACKGROUND The purpose of this study was to comparison of unilateral and bilateral percutaneous vertebroplasty in the treatment of severe vertebral compression fractures. METHODS Sixty-four severe vertebral compression fractures patients were treated in our hospital were randomly divided into group A and group B(n = 32). Group A received Percutaneous vertebroplasty (PVP) treatment by unilateral vertebral pedicle approach. Group B received PVP treatment by bilateral vertebralpedicle approach. Visual Analogue scale (VAS) score and Oswesty Disability Index (ODI) were recorded before surgery, and at 1d,1 month, and 6 months after operation. Also, the puncture path, needle position, intraoperative bone cement injection volume, bone cement dispersion, intra-operative and postoperative complications were observed. RESULTS Sixty-four vertebrae were successfully punctured.The postoperative VAS,ODI were lower than preoperative, showed statistical difference compared with the preoperative VAS, ODI, but there are no difference between Group A and Group B.The cement leakage and operation time is lower in group A than that in Group B. CONCLUSION PVP by unilateral vertebral pedicle approach in treating severe vertebral compression fractures can significantly relieve pain and promote functional recovery, which has advantages such as convenient operation and low complication rate.
