title: The clinical comparative study on high and low viscosity bone cement application in vertebroplasty.
abstract: OBJECTIVE
  To investigate the clinical effect of high and low viscosity bone cement in vertebroplasty for treatment of osteoporotic vertebral compression fractures.
  
  
  METHODS
  40 cases of patients with osteoporotic thoracolumbar compression fractures admitted into department of orthopeadics in our hospital were reviewed. All patients were divided into high viscosity bone cement group (20 cases) and low viscosity bone cement group (20 cases). Visual Analog Score (VAS), Oswestry Dability Index (ODI), injured vertebral height restoration (Cobb Angle) and bone cement leakage rate, subsequent fracture rate of vertebrae body with or without surgical treatment were measured.
  
  
  RESULTS
  Compared with the low viscosity bone cement group, the VAS score, ODI score and Cobb angle of high viscosity bone cement group had a statistical difference (P<0.05). The postoperative complications in high viscosity bone cement group were lower than those in low viscosity bone cement group (P<0.05).
  
  
  CONCLUSIONS
  Compared with low viscosity bone cement, bone cement leakage rate reduced obviously in high viscosity bone cement with good clinical effect and prognosis in vertebroplasty for treatment of osteoporotic thoracolumbar compression fractures.
