UNASSIGNED: This study aims to investigate clinical effects of protruding after percutaneous vertebral plasty (PKP holds) for treatment of chronic @entity158 (CPOVCFs), and assess its safety and effectiveness. One hundred and eighteen CPOVCFs @entity1 were included, and analyzed and followed up therapeutic effects of PKP holds. All of these @entity1 were divided into NIVC (73 cases) and IVC (45 cases) group. Comparing operation time, bone cement perfusion, @entity158 intensity modulus visual grading scoring, @entity717 index, @entity174 fanterior relative height, local convex Angle, and surgical complications between the two groups. There were no significant differences between two groups for operation time of PKP holds (P>0.05). Amount of bone cement injection in IVC groups was significantly higher compared to NIVC group (P<0.05). @entity158 intensity visual modulus ratings and @entity717 index were significantly improved in both groups after surgery and postoperative follow-up period compared to pre-operation (P<0.05). @entity174 fanterior margin relative height and local convex angle were also significantly improved (P<0.05). @entity174 fanterior margin relative height was also significantly improved for IVC compared to NIVC group (P<0.05). There were no differences for bone cement leakage rate and adjacent segment @entity174 between two groups (P>0.05). But there was a case of bone cement loose, which needs to be treated for further step. In conclusion, PKP holds is a kind of effective and safe method for the IVC and NIVC @entity1 . Especially for the IVC @entity1 , PKP holds can significantly improve the @entity174 fanterior margin relative height.
