The Clinical Research Of Osteoporoticvertebral Body Compression Fractures Treated By Percutaneous Kyphoplasty

Objective To investigate the correlations between cement volume injected and the therapeutic results in percutaneous kyphoplasty (PKP)for osteoporotic vertebral compression fracture in the elderly patients，and the prevention of cement leakage.Methods155patients who underwent single level PKP for OVCFs from September2009to September2013were retrospectively reviewed．The correlative factors including sex，age，history of trauma，vertebral level treated，presence or obesence of an intravertebral cleft，cement volume injected，preoperative degree of vertebral compression，cement leakage，postoperative regain of vertebral compression，the graded of Vas，postoperative improvement rate of Vas. Bivariate Correlation，multiple linear regression，Binary logistics regression analysis method were used for the variable analysis.Result There were no significant association between the volume of cement injected and cilical therapeutic results. Vertebral level treated and preoperative degree of vertebral compression were the influence factors of volume of cement injected. History of trauma, preoperative degree of vertebral compression were the influence factors of postoperative improvement rate of Vas.Preoperative degree of vertebral compression and intravertebral cleft were risk factors of cement leakage.Conclusion PKP holds the diseases of bone cement injection quantity attack had a greater influence on the operation of their own conditions, and can not directly reflect the curative effect is good or bad. So the operator should not achieve better filling degree and importune bone cement injection quantity, should be enough is enough, to ensure clinical curative effect and reduce complications.
