摘要
目的探讨无骨折脱位型颈脊髓损伤程度的影响因素。方法回顾性分析44例无骨折脱位的颈脊髓损伤病例的MRI资料。从矢状位和轴位图像观察记录:脊髓损伤的长度,脊髓损伤处椎间盘突出最大径,椎间盘突出类型,脊髓损伤处椎管前后径、黄韧带厚度、椎体后缘骨赘有无和脊髓损伤节段,同时记录患者的年龄和性别。以脊髓损伤长度为应变量,以性别、年龄、椎间盘突出最大径、椎管前后径、椎间盘突出类型、黄韧带厚度、椎体后缘骨赘有无、脊髓损伤节段为自变量,进行多因素相关性分析。结果①44例中,脊髓损伤的长度为3~22mm,椎间盘突出的最大径为4~8mm,椎管前后径为4~9mm,黄韧带厚度为2—7mm,脊髓损伤平面位于C。~C,水平。②颈脊髓损伤的程度与颈椎间盘突出程度、颈椎管径前后径、颈椎黄韧带的厚度、颈脊髓损伤节段相关,差异有显著性意义(P〈0、01)。结论无骨折脱位的颈脊髓损伤的程度与颈椎间盘突出程度正相关,与颈椎管径前后径负相关,与颈椎黄韧带的厚度、颈脊髓损伤节段相关,与椎间盘突出的类型、椎体后缘有无骨赘、性别和年龄无关。
Objective To study the influencing factors for the extent of cervical spinal cord injury without fracture and dislocation. Methods MRI manifestations in 44 cases of cervical spinal cord injury without fracture and dislocation were reviewed retrospectively. The investigation was carried out in the following aspects : the extent of spinal cord injury, the maximum radius of intervertebral di'sk protrusion at impaired region, the type of intervertebral disk protrusion, the diameter of vertebral canal, the thickness of ligamenta flava, the osteophyte existed in the posterior border of the vertebra, the level of spinal cord injury in the sagittal and coronal images of MRI, as well as patient's gender and age. The extent of spinal cord injury as dependent variable and the other parameters mentioned above as independent variables were studied by multiple factor analysis. Results Among the 44 cases, the length of cervical spinal cord injury was 3 - 22 mm, the maximum radius of intervertebral disk protrusion was 4 - 8 mm, the diameter of the vertebral canal was 4 - 9 mm, the thickness of ligamenta flava was 2 - 7 mm, and the level of the cervical spinal cord injury was from C4 to C7. Multiple factor analysis indicated that the extent of cervical spinal cord injury was related with the extent of cervical intervertebral disk protrusion, the diameter of cervical vertebral canal, the thickness of cervical ligamenta flava and the level of cervical spinal cord injury ( F = 4. 09, P〈0.01 ). Conclusion The extent of cervical spinal cord injury without fracture and dislocation has positive relationship with the extent of cervical intervertebral disk protrusion and negative relationship with the diameter of cervical vertebral canal and the level of cervical spinal cord injury. It is related with the level of spinal cord injury, but unrelated with the osteophyte existed in the posterior border of the vertebra as well as the gender and age of the patients.
