摘要
目的分析16层螺旋CT多平面重建对青壮年腰椎间盘突出程度与椎体后缘骨质反应的关系,为临床治疗提供依据。方法38例有腰腿疼痛症状及体征并进行16层螺旋CT检查诊断腰椎间盘突出的患者的影像资料进行回顾性分析。结果38例患者中CT显示共61节腰椎间盘突出,中央型突出21节(34%),旁中央型28节(46%),椎间孔型12节(20%),以腰5/骶1节段突出最常见,约占51%。相应61节椎体表现为,骨质硬化32节(52%)、增生9节(15%)、骨质缺损并骨块20节(33%),均伴椎管狭窄或椎间孔狭窄;合并后纵韧带骨化7例(18%),椎间盘突出轻度25节(41%)、重度36节(59%)。旁中央型突出和重度突出易导致椎体后缘骨质缺损及椎间孔狭窄(P<0.05)。结论青壮年腰椎间盘突出程度较重,均伴有骨质变化,软骨结节、后纵韧带钙化、椎间孔狭窄常见。
Objective To analyze the relationship of lumbar intervertehral disc protrusion and vertebral bone reaction by CT multiplanar reconstruction, in order to improve the value for therapy. Methods The clinical and CT representations of 38 cases with lumbar intervertebral disc protrusion in the group of young aged patients were retrospectively analyzed. Results There were 61 iutelwertehral disc protrusion of 38 cases showed by 16 slice CT, including： central type （21 intervertebral disc, 34%）, para-central type（28 intervertebral disc, 46%）, foraminal type （12 intervertebral disc, 20%）. The location of disc herniation occurred frequently at the level of L5-S1 intervertebral disc （51%）. CT signs of the lumbar and/or sacral vertebral body included： thirty-two vertebral （52%）showed osteoselerosis, nine vertebral （15%）showed hyperostosis, twenty vertebral （33%）represented that a defect in the posterior superior margin of the lumbar and/or sacral vertebral body and the bony fragments, spinal canal stenosis and lumbar lateral re- cessus narrow, seven cases （18% ） showed posterior longitudinal ligament calcification. The degree of intervertebral disc protrusion were showed serious in the 36 intervertebral disc（59%）, other 25（41%） intervertebral disc were showed a little. Both para-central type and the serious intervertebral disc protrusion were mostly caused the defect of vertebral posterior and foraminal stenosis（P〈0.05）. Conclusion The lumbar intervertebral disc protrusion in the group of young aged patients is mostly serious level, the complicated CT signs are lumbar posterior marginal intraosseous cartilaginous node; and spinal canal stenosis, posterior longitudinal ligament calcification.
