摘　　要：目的了解胸腰段椎间盘突出症患者相应脊柱曲度状况，探讨胸腰段椎间盘突出与脊柱矢状曲度的关系。方法拍摄、收集27例胸腰段椎间盘突出症患者卧位脊柱胸腰段正侧位x线片，测量其矢状位胸腰段（T10-L2）、上胸腰段（T10-L12）及下胸腰段（T12-L2）Cobb角。用同样方法拍摄37名健康人的卧位脊柱胸腰段正侧位X线片并测量其T10-L2、T10-L12及T12-L2Cobb角，以作为对照组，用SPSS统计软件将两组资料进行统计分析。结果胸腰段椎间盘突出症患者和对照组人群的年龄比较，t=-1．190，P〉0．05，差异无统计学意义。胸椎间盘突出症患者的T10-L2，T10-L12，T12-L2Cobb角均大于对照组人群，WilcoxonW统计值分别为812．500，916．500及t=-8．545，P〈0．01，差异无统计学意义。结论胸腰段椎间盘突出患者胸腰段后凸角度比正常人群的胸腰段后凸角度更大。胸腰段后凸角度的增大可能导致相应节段椎间盘应力分布发生改变，这可能是胸椎间盘退变、受损及突出的原因之一。Objective To understand the curve of thoracolumbar junction in patients with thoracolumbar intervertebral disc herniation and analyze the relation between thoracolumbar intervertebral disc herniation and spinal sagittal curve. Methods The radiographic films of thoracolumbar junction of spine from 27 patients with thoracic disc herniation and 37 healthy persons as control were taken at reclining position. The Cobb angles of sagittal plane of thoracolumbar junction of spine were measured and statistically compared by SPSS （statistics package for social science）. Results The Cobb angles of TIO-L2, T10-L12 and T12-L2 in patients with thoracolumbar intervertebral disc herniation were greater than those in healthy controls respectively. Conclusion The Cobb angles of sagittal plane of thoracolumbar junction of spine in patients with thoracolumbar intervertebral disc herniation are greater than those in healthy controls. The abnormal spinal curve is possibly responsible for thoracolumbar intervertebral disc herniation by abnormal biomechanical action.
