Clinical application of percutaneous vertebroplasty for spinal pain relief

Objective To study the pain-relieved efficacy of percutaneous vertebroplasty (PVP) in the treatment of diseases in spine vertebrae. Methods Eighty-one patients with 103 vertebrae underwent PVP, including 57 osteoporosis in 42 cases and 46 vertebral tumors in 39 cases. Intraosseous venography was performed followed by injecting bone cement under the fluoroscopy. The score of visual analogue scale point (VAS) (10-point scale) before vertebroplasty, 72 hours after vertebroplasty was recorded respectively. Result of pain relief and complications were observed. Results The procedure was technically successful in all patients. Bone cement leakage into adjacent paravertebral soft tissue occurred in 15 cases. The score of VAS was(2.81±1.25mm) marks at 72 hours after PVP significantly lower than the average score of VAS before treatment(8.15±1.31mm)(p0.01).The analgestic effectiveness was 86.4%. The analgestic time lasted 6 months. Conclusion PVP can provide significant pain reduction in the treatment of patient with osteoporsis and vertebral tumors disease.
