摘要
目的探讨脊髓型颈椎病(cervical spondylotic myelopathy,CSM)患者先天性颈椎管狭窄(cervical spinal stenosis,CSS)与颈椎MRI改变及预后的关系。方法回顾性分析自2006年11月至2009年11月,采用前路、后路或前后路联合手术治疗的286例CSM患者的病例资料,根据患者是否存在CSS将患者分为两组,在MRI T2加权像上评价脊髓高信号的等级以及脊髓受压程度。记录患者日本骨科学会评分标准(Japanese Orthopaedic Associatio,JOA)评分、病程和体征,包括感觉减退或者消失、Hoffman征、Babinski征、腱反射。结果在CSM患者中CSS的发生率为33.6%,先天性CSS组的年龄、JOA评分、病程均大于无CSS组,术后临床改善率小于无CSS组。两组之间性别的差异无统计学意义(χ2=0.006,P=1.00),两组之间的颈椎MRI T2加权像脊髓高信号发生率的差异有统计学意义(χ2=62.396,P<0.001),CSS组脊髓高信号的发生率为70.8%,无CSS组脊髓高信号的发生率为22.6%。先天性CSS组脊髓受压程度相对于无CSS组严重,且先天性CSS组患者体征的数目相对较多。应用多元线性回归分析法得出术后改善率与CSS、病程、临床体征的数目和年龄有关(R2=0.565)。结论先天性CSS患者出现CSM时往往脊髓受压程度较重、MRI T2加权像脊髓内高信号出现的概率大,病程长且预后较差。
