椎间盘源性腰痛的诊断及手术治疗

目的:分析和总结椎间盘源性腰痛的诊断及手术疗效。方法:对50例腰痛患者应用MRI及椎间盘造影进行术前检查,并对确诊患者行后路病变节段的椎间盘切除、椎间融合、椎弓根螺钉内固定术手术治疗,对治疗结果作回顾性分析。结果:39例确诊患者经治疗后,效果确切,优良率92.3%。统计学结果显示,术前MRI信号改变,包括高信号(HIZ)现象以及终板信号改变,与椎间盘造影阳性的结果在本组患者中显示有较高相关性。结论:MRI、椎间盘造影可为椎间盘源性腰痛的诊断提供重要的依据;后路椎间盘切除、椎体间融合、椎弓根螺钉内固定术治疗椎间盘源性腰痛疗效确切。

The diagnosis and treatment of discogenic low back pain

Objective:To study diagnosis and treatment of discogenic low back pain.Method:50 cases with clinical suspicion of low back pain were examined by MRI and discography.The results were analyzed retrospectively.Result:High intensity zone(HIZ) and signal changing of end plate in MRI was highly correlated with the positive discography,and final diagnosis was made according to the positive discography.39 cases who were finally diagnosed as discogenic low back pain underwent discectomy with pedical screw fixation and fusion,92.3% of excellent and good results was achieved.Conclusion:MRI can be used to select the suspicions patients,discography is the most important method to make diagnosis of discogenic low back pain.A certain therapeutic effect can be obtained by lumbar vertebrae stability reconstruction.
