Application of modified bone cement injection sleeve in percutaneous vertebral plasty / 实用医学杂志

ABSTRACT

Objective To comparemodified bone cement injection sleeve (front end closed,unilateral opening) and traditional straight push bone cement sleeve in percutaneous vertebral plasty (PVP) for clinical application.Methods From January 2015 to June 2016,78 patients with PVP indications of single osteoporotic vertebral compression fracture (OVCF) were randomly divided into a study group and a control group (39 patients for each group),and both groups received PVP under DSA.Intraoperative X-ray exposure dose,surgical duration,postoperative bone cement leakage,VAS score (preoperative and postoperative 3 days and 6 months),and refracture rate after half a year and postoperative bone cement distribution were compared between the two groups.Results Both groups received a follow-up for 6 to 12 months.5 patients had paravertebralleakage in the study group,while 9 patients developed paravertebralleakage and orie patient had anterior leakage in the control group.No neurologic and vascular injury occurred,no pulmonary embolism and other serious complications developed.The patients in both groups were followed up for half a year without re-fracture.The radiation dose and surgical duration in the two groups were statistically significant (P＜0.05).Bone cement injection and postoperative VAS scoresdid not differ obviously between the two groups (P＞0.05),There was no significant difference between the two groups in distribution of bone cement (P＞0.05).The bone cement leakage rate was lower in the study group than in the control group,with a statistical significance (P＜0.05).Conclusions The improvement in bone cement injection sleeve can shorten surgical duration,reduce intraoperative X-ray exposure,and decrease the rate of leakage of bone cement.It is worth popularizing clinically.
