摘　　要：目的 :通过准确描述和测量腰椎的运动参数,探究临床腰椎不稳的发病机理,最终找到定量、客观的检查方法以及相应的临床诊治标准,用于腰椎稳定度评估。方法:利用计算机模式识别技术,借助生物力学的研究方法以及腰椎椎体成像动态追踪系统,采集100例健康受试者腰椎各椎体的运动参数。对腰椎椎体进行自动追踪并进行运动参数的数据统计。结果:建立了正常人群腰椎运动的动态X线影像数据库,可清晰显示出正常人群腰椎椎体的运动范围、位移、旋转角度及椎间位移等特征。结论:该数据库的建立,对正常人群腰椎椎体运动特征进行了界定,可为医疗中进行正常组和病患组的对比分析做准备工作。Objective To describe and measure accurately the motion parameters of lumbar vertebrae and to explore the pathogenesis of clinical llumbar instability, so as to determine quantitative and objective examining method and corresponding clinical diagnosis and treatment criteria to assess the stability of lumbar spine. Methods The lumbar motion parameters of 100 healthy persons were collected with computer pattern recognition technology, biomechanical research method and lumbar vertebral body imaging dynamic tracking system, and then underwent statistical analysis. Results Dynamic X-ray image database was established on healthy population lumbar motion, which described the motion range, displacement, rotation angle, intervertebral displacement and etc. Conclusion The database defines the lumbar motion characteristics of healthy population, and lays a foundation for the comparison between healthy and ill populations.
