【摘要】：目的:通过双能X线骨密度仪对绝经后女性椎体脆性骨折的评估,探讨其发生的危险因素。方法:对来院体检的203例50岁以上绝经妇女用双能X骨密度测量仪(dual-energy x-ray absorptiometry,DXA)进行椎体骨折评估(verterbral fracture assessment,VFA),并检测不同部位骨密度及相应T值,收集所有受检者一般资料。根据有无椎体骨折及椎体骨折部位分组。结果:胸椎及胸腰椎骨折组骨密度及T值均低于无椎体骨折组;骨质疏松时与无椎体骨折组比较差别有统计学意义(P0.05)。腰椎骨折组骨密度、T值及骨量变化则均与无椎体骨折组差别无统计学意义。增龄、全髋骨密度及T值降低是椎体骨折的危险因素。结论:骨密度(bone mineral density,BMD)及T值的降低对绝经后妇女胸椎及胸腰椎骨折椎体脆性骨折有重要的预测价值,对腰椎骨折则有局限性。增龄、全髋骨密度及T值降低是椎体脆性骨折的危险因子。对绝经后妇女椎体脆性骨折的防治在重视骨密度的同时要联合进行椎体骨折评估。
[Abstract]:Objective: to evaluate the fracture of vertebral body in postmenopausal women by dual energy X-ray absorptiometry. Methods: 203 postmenopausal women over 50 years old who came to our hospital were examined by dual-energy x-ray absorptiometry (DXA) to evaluate the vertebral body fracture, and to detect the bone mineral density (BMD) and the corresponding T value of different sites. The general data of all the subjects were collected and grouped according to the vertebral fracture or not. Results: the bone mineral density (BMD) and T value of the thoracic and thoracolumbar fractures were lower than those of the non-vertebral fracture group. There was significant difference between the osteoporosis group and the non-vertebral fracture group (P 0.05). The changes of bone density T value and bone mass in the lumbar vertebra fracture group were not significantly different from those in the no vertebral fracture group, and the changes of bone mass and bone density in the lumbar vertebra fracture group were not significantly different from those in the vertebral fracture group. Conclusion: the decrease of bone mineral density and T value in postmenopausal women has important predictive value for the brittle fracture of thoracic and thoracolumbar vertebrae in postmenopausal women. Aging, reduction of total hip density and T value are the risk factors of brittle fracture of vertebral body. The prevention and treatment of brittle fracture of vertebral body in postmenopausal women should pay attention to bone mineral density and evaluate the fracture of vertebral body at the same time.
