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.
ABSTRACT
Objective To observe clinical efficacy of osteoporotic thoracolumbar compression fractures treated by manual reduction with percutaneous vertebroplasty. Methods Totally 82 patients with osteoporotic thoracolumbar compression fractures were randomly divided into treatment group (43 cases) and control group (39 cases). The treatment group received the manual reduction combined with percutaneous vertebral plasty, while the control group only received percutaneous vertebral plasty. Lumbar back pain VAS scores, vertebral anterior height and spine after convex Cobb angle before and after operation in the two groups were compared. Results There was statistical significance among VAS pain score, spine after convex Cobb angle and anterior flange height in the two groups (P0.05), while there was statistical significance in spine after convex Cobb angle and anterior flange height in the two groups (P<0.05);There was statistical significance among VAS pain score, spine after convex Cobb angle and anterior flange height in the two groups in the 3rd month after operation (P<0.05). Conclusion Manual reduction combined with percutaneous vertebral plasty can improve the lower back pain, restore vertebral body height and correct spine after contex Cobb angle of osteoporotic thoracolumbar compression fractures, which is better than pure percutaneous vertebral plasty.
