摘  要:目的通过腰椎椎间孔狭窄症(FS)、腰椎椎间孔型椎间盘突出症(FH)与腰椎管狭窄症(LCS)的比较,了解腰椎椎间孔部神经根受压的临床表现和影像学特征。方法对2004年1月至2009年8月在我院手术治疗腰椎FS(FS组,12例)、腰椎FH(FH组,18例)和LCS(LCS组,21例)患者的资料进行回顾性分析。评价内容包括日本骨科协会评分、椎间盘变性程度、椎间孔部的形态测量及MRI影像学表现。结果LCS组、FS组和FH组问椎间孔前后径分别为(11.4±3.1)、(8.3±3.0)、(8.3±2.4)mm,FS组、FH组与LCS组相比椎间孔前后径要小,差异有统计学意义(P〈0.01)。LCS组、FS组和FH组患者椎间孔上部高度分别为(9.4±1.2)、(7.6±2.2)、(9.1±2.0)mm,与LCS组和FH组比较,FS组的椎间孔上部高度短,差异有统计学意义(P〈0.01)。FS组、FH组和LCS组中,MRI影像出现椎间孔部神经根“中断征”的阳性率分别为66.7%(8/12)、77.8%(14/18)、28.6%(6/21),FH组出现频率最高,与其他2组比较,差异有统计学意义(P〈0.05)。结论了解腰椎椎间孔部神经根损害的临床和影像学特征有助于对此类疾病的诊断及治疗。Objective To analyze lumbar nerve root compression with intelvertebral foramina via comparing foraminal stenosis (FS) and foraminal hernia (FH) with lumbar canal stenosis (LCS). Methods Fifty one patients ( 12 cases of foraminal stenosis, 18 cases of foraminal hernia and 21 cases of lumbar canal stenosis) who underwent surgical treatment from Jan 2004 to Aug 2009 were analyzed retrospectively. Japanese orthopaedic association scores, intervertebral disc degeneration, anatomical measurements of the nerve root foramina and the MRI findings were reviewed. Results Anterior-posterior diameters of the nerve root foramina in the FS group and FH group were smaller than these in the LCS group [ LCS ( 11.4 ± 3.1 ) mm, FS (8.3 ± 3.0) mm and FH ( 8. 3 ± 2.4 ) mini. More degenerated discs and shorter length of upper part of the nerve root foramina were seen in FS group ( P 〈0. 01 ). The MRI images of so-called black out nerve root foramina were positive in 66.7% (8/12) of FS cases and 7.8 % ( 14/18 ) of FH cases. Conclusion Analyzing clinical and imaging characteristics of foraminal nerve root disorders of the lumbar spine can help diagnosis and treatment.
