双能X线吸收法对腰椎间盘突出症患者骨密度的评价

Bone mineral density assessment in patients with lumbar disc herniation by dual energy X-ray absorptiometry

目的利用双能X线吸收法(DXA)研究腰椎间盘突出症患者与正常人骨密度差异,探讨腰椎间盘突出症对骨密度的影响,旨在研究骨量减低的危险因素。方法应用双能X线吸收法测量50例腰椎间盘突出患者和50例健康志愿者的腰椎骨密度,对得到的病例组和对照组骨密度进行比较分析。结果腰椎间盘突出症组患者骨密度较正常对照组骨密度值无统计学意义(P>0.05)。结论双能X线吸收法测量病例组与对照组的骨密度值,腰椎间盘突出症患者骨密度未见明显降低,腰椎间盘突出症对骨密度影响不明显,腰椎间盘突出症并非骨量减低的危险因素。

Objective By comparing the bone mineral density （BMD） in patients with lumbar disc herniation and healthy controls, to study the influence of lumbar disc herniation on bone mineral density, using the dual-energy X-ray absorptiometry measuring BMD, the purpose of this study was to discuss the risk factor of reducing bone mineral content. Methods We used the dualenergy X-ray absorptiometry to measure bone mineral density of lumbar spine of the 50 patients and 50 healthy controls.All of the data was for statistical analysis. Results The bone mineral density had no significant change between the patients and healthy controls （P 〉 0.05）. Conclusion By using the dual-energy X-ray absorptiometry to measure bone mineral density of patients and healthy controls, the bone mineral density in patients with lumbar disc herniation had not seen significantly reduced. Lumbar disc herniation didn＇t influence the bone mineral density.Lumbar disc herniation was not a risk factor for reducing bone mineral content.
