Abstract:
injection). At the 5th, 10th and 15th months after operation, L2, L4 bone mineral density, L2, L4 maximum bending and compressive load, the ratio of anterior and posterior heights of L3 vertebrae to average height of L2 and L4 vertebrae, and the sagittal Cobb angle of L2 and L4 vertebrae were detected. RESULTS AND CONCLUSION:The bone mineral density, maximum bending and compressive load, vertebral height ratio at different time points after operation in experimental group were higher compared with the preoperative level (P < 0.05). The sagittal Cobb angle in experimental group was smaler compared with the preoperative level (P < 0.05). In the control group, the bone mineral density, maximum bending and compressive load at different time points after operation were al higher compared with preoperative level (P < 0.05). There were no significant difference of the vertebral height ratio and sagittal Cobb angle compared with the preoperative level. The bone mineral density, maximum bending and compressive load, vertebral height ratio at different time points after operation in experimental group were higher compared with the control group (P< 0.05). The sagittal Cobb angle was smaler compared with the control group (P < 0.05). These results demonstrate that percutaneous kyphoplasty bone cement injection can better improve the bone density, carrying capacity and kyphosis of osteoporosis fractures adjacent vertebrae.
