QCT测量腰椎间盘突出患者骨密度的研究

目的利用QCT（定量CT）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。方法应用定量CT技术测量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的骨密度较正常对照组骨密度值无显著性差异（P〉0.05）。结论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的影响不明显,腰椎间盘突出症并非骨量减低的危险因素。

Research of bone mineral density measurement by Quantitative computed tomography in patients with lumbar disc herniation

Objective By compare the bone mineral density(BMD) of people who suffer from lumbar disc herniation with the normal,and to study the influence of lumbar disc herniation on bone mineral density,using quantitative computed tomography measuring BMD,the purpose of this study was to discuss the risk factor of reducing bone mineral content.Methods We used quantitative computed tomography to measure bone density of lumbar vertebrae of the 50 patients and 50 healthy volunteers.All of the data was for statistical analysis.Results The bone mineral density had no significant change between the lumbar disc herniation patients and the normals(P >0.05).Conclusion The bone mineral density of lumbar disc herniation patients had not seen significantly reduced.Lumbar disc herniation did not influence the bone mineral density.Lumbar disc herniation was not a risk factor for reduced bone mineral content.
