A Comparison of high viscosity and low viscosity bone cement vertebroplasty for severe osteoporotic vertebral compression fractures

Abstract

Introduction: Our aim in this clinical trial was to compare the safety and efficacy of highviscosity cement (HVC) with low-viscosity cement (LVC) for the treatment of osteoporotic vertebrae fractures in terms of pain, functional capacity and cement leakage in the percutaneous vertebroplasty procedure (PVP). Methods: From March 2013 to February 2015, 76 patients with vertebrae compression fracture who were admitted into hospital and treated with PVP were reviewed. Pre- and postoperative clinical characteristics of each patient were obtained by using The Visual Analog Scale (VAS) score to evaluate back pain, Oswestry Disability Index (ODI) as a functional assessment. Cement leakage,injected cement volume and the complications assessed due to medical records. Results: VAS and ODI scores improved (P<0.05) significantly in the two groups postoperatively on the other hand there was no significant change between two groups (P>0.05).Paravertebral cement leakage was significantly higher in the LVC group (P<0.05). Pulmonary cement embolism was also significantly higher in LVC group (P<0.05). Conclusion: HVC had lower complication rates with similar clinical results in the comparison with LVC.
