Abstract:
BACKGROUND:Because it can reduce the risk of postoperative bone cement leakage, percutaneous kyphoplasty is increasingly used for treatment of severe osteoporotic thoracolumbar vertebral compression fractures. Studies have found that injection of mixed bone cement with high viscosity can significantly reduce the leakage of bone cement. OBJECTIVE:To compare the therapeutic efficacy of percutaneous vertebroplasty with high viscosity bone cement and percutaneous kyphoplasty with standard viscosity bone cement in the treatment of severe osteoporotic thoracolumbar vertebral compression fractures. METHODS:Eighty patients with severe osteoporotic thoracolumbar vertebral compression fractures were enroled and randomized into vertebroplasty group and kyphoplasty group, 40 patients in each group. Visual analog scale score and Oswestry disability index score were compared between groups before and after treatment. Incidence rate of bone cement leakage and other complications were also compared between two groups after treatment. RESULTS AND CONCLUSION:No significant difference was found between the visual analog scale scores of two groups after treatment (P> 0.05). Patients in the two groups al presented with good recovery of spinal function after treatment, and there was no difference in the Oswestry disability index scores between groups at 3 months after treatment (P> 0.05). The incidence rate of bone cement leakage was 45% in the vertebroplasty group and 30% in the kyphoplasty group, with a significant difference (P < 0.05). But the patients in both groups showed no obvious clinical symptoms and underwent no treatment. After treatment, al patients had no pulmonary embolism, bone cement toxicity, spinal cord and nerve root injury. These findings show that there is no significant difference between percutaneous vertebroplasty and kyphoplasty with high-viscosity bone cement in the folowing aspects: pain improvement, recovery of the spinal function, incidence rate of bone cement leakage and clinical efficacy.
