Abstract：Objective To investigate the factors involved in delayed vertebral union after PKP in patients with OVCF.Methods This retrospective case-control study enrolled patients who had been treated using single-segment PKP from January 2011 to January 2012.Demographic and surgical data were collected to analyze the risk factors asso-ciated with delayed vertebral union after PKP.Results A total of 580 patients with OVCF treated with PKP were en-rolled in the study.Of these,29 (5.0%)had experienced delayed vertebral union and they were paired with age-and sex-matched patients who experienced vertebral union.Multivariate analyses revealed that a low preoperative bone mineral density (OR 0.114,95% CI 0.014~0.900),the presence of an intravertebral cleft (OR 35.88,95% CI 1.690~762.034), and a higher restoration rate of vertebral height (OR 4.053,95% CI 1.217~13.496)were independently associated with delayed vertebral union.Conclusion Preoperative BMD,intravertebral cleft,and restoration rate of vertebral height ap-pear to be risk factors for delayed vertebral union after PKP in patients with OVCF.
