摘要
目的探讨单纯腰椎间盘突出与腰椎管狭窄症的影像学测量值间的差异及其相关性。方法对178例单纯腰椎间盘突出和162例腰椎管狭窄症患者经手术治疗后的X线、CT、MRI资料进行回顾性对照分析。测量腰椎曲线指数(LCI)、腰椎前凸度(Cobb角)、椎间盘突出指数(IDH)、硬膜囊横截面积(CSADS)、侧隐窝前后径(A-PDLR)(骨性标志),对所测量的数据进行统计学分析。结果腰椎间盘突出组,X线显示为腰椎生理曲度明显变小或消失,并多伴有侧弯;腰椎管狭窄组,X线显示为腰椎生理曲度明显加大,多不伴有侧弯,二者的差异具有显著性(P<0.01)。腰椎间盘突出程度与腰椎生理曲度呈负相关(r=-0.732,P<0.05);腰椎管狭窄程度与腰椎生理曲度呈正相关(r=0.605,P<0.05)。结论腰椎间盘突出和腰椎管狭窄症的腰椎生理曲线不同,突出和狭窄程度与腰椎生理曲线有相关性。
Objective To study the difference and relativity of the radiological measure values between simple hernia of intervertebral discs and lumbar spinal stenosis. Method The X-ray ,CT, MRI of 178 cases simple hernia of intervertebral discs and 162 cases lumbar spinal stenosis were analyzed after operation, and the LCT, Cobb angle, IDH, CSADS, the anterior-posterior diameter of lateral recess were measured. Result X-ray showed that the lumbar lordosis decreased significantly and associated with scoliosis mostly in the team of simple hernia of intervertebral discs, hut an obvious increase of lumbar lordosis in lumbar spinal stenosis with no associating with scoliosis. The difference between the two is significant（ P〈0.01 ） .The extent of hernia of intervertebral discs has negative relativity with lumbar lordosis （ r=- 0.732, P〈0.05 ） ; the extent of lumbar spinal stenosis has positive relativity with lumbar lordosis （ r=0.605, P〈0.05 ） . Conclusion The lumbar curves of hernia of intervertebral discs and lumbar spinal stenosis are different, and there is relativity for the extent of the hernia and stenosis with lumbar curve.
