A Study on Extension－Flexion Dynamic Lumbar Spine Radiographsin Patients with Lumbar Intervertebral Disc Herniation

The study has collected a set of clinical materials such as extension-flexion dynamic lum-bar spine radiographs and computerized x-ray tornography of lumbar spine and quantified physical exami-nation from 32 patients with lumbar intervertebral disc herniation, who had gone through a suocessful con-servative treatment. The collection was conducted twice before and after the treatment. With the help oft-test and linear correlation analysis, the study suggests that extensionflexion radiograph of lumbar spineis of important clinical significance in weighing the clinical state of an individual patient, especially forthose who receive conservative treatment. The study emphasizes that the biomechanical disturbance oflumbar spinal column may be from another important pathological element along with the irritation of thenerve root by herniated disc tissue in the pathomechanics of lumbar disc herniation. There is also somediscussion of the computerized X-ray tomography diagnosis in this study. Above all, the author provides anew angle of viewing the trouble by one of the soul principles of traditional Chinese medicine: concept ofholistics .

腰椎管内突出髓核的临床意义探讨──附44例腰椎间盘突出症患者与73例正常人CT资料的三维分析

目的：探讨突出髓核组织在椎管内空间占位的临床意义。方法：44例腰椎！司盘突出症患者（A组）及73例正常人（B组，其中22例有腰椎间盘突出者为B1组，余为B2组）观察：（1）突出椎间盘CT超薄扫描三维数据；（2）腰椎X线平片及动力学摄片测量数据；（3）分析两组突出髓核组织的体积、表面积、突出髓核椎管内相对占位空间以及腰椎结构和功能等情况的差异和相关性等。结果：正常人群中无症状髓核突出（B1）者高达30，1％，但突出的髓核比患者组（A组）明显要小，其椎管内相对空间占位也较小；患者腰椎结构与功能均不如B1组，但无显著性差异。结论：（1）腰椎管对突出髓核组织的空间占位具有相当的容纳能力，但容纳植限尚无法确定；（2）较大的髓对支突出会减低椎管代偿容纳的可能性，容易引发结构紊乱及神经根刺激。
