Abstract:
BACKGROUND:Percutaneous vertebroplasty with bone cement injection for osteoporotic vertebral compression fractures can quickly relieve pain and increase vertebral strength, but vertebral re-fractures often occur because of osteoporosis. OBJECTIVE:To investigate the therapeutic effect of percutaneous vertebroplasty with bone cement injection combined with zoledronic acid in the treatment of osteoporotic vertebral compression fractures. METHODS:Six patients with osteoporotic vertebral compression fractures were enrol ed, including two males and four females, aged 60-86 years. These patients with T12-L4 vertebral fractures underwent percutaneous vertebroplasty with polymethyl methacrylate acrylate bone cement treatment. At 4 weeks after bone cement injection, al patients were administrated with intravenous injection of zoledronic acid (100 mL:5 mg) as anti-osteoporosis treatment, 30 drops per minute, once a year, for consecutive 2 years. The 2-year periodic imaging was performed to observe the clinical efficacy on vertebral compression fractures, bone density and adjacent vertebral fractures. RESULTS AND CONCLUSION:At 48 hours after bone cement injection, pain symptoms were relieved in the six cases. At the end of 2-year fol ow-up, fractures healed in al the six cases without delayed union or nonunion, and there was no bone cement leakage, nerve root compression, dural involvement, needle opening or wound infection and pulmonary embolism;the bone density was significantly higher than that before treatment (P<0.05), and no adjacent vertebral fractures occurred. These findings indicate that the percutaneous vertebroplasty with bone cement injection combined with zoledronic acid can significantly relieve pain, improve vertebral stability and bone density, and reduce the incidence of adjacent vertebral fractures in patients with osteoporotic vertebral compression fractures.
