目的 探讨无骨折脱位型颈脊髓损伤案例中外伤与损害后果因果关系法医学鉴定的要点.方法 收集25例无骨折脱位型颈脊髓损伤的法医学鉴定案例资料,总结被鉴定人的年龄、致伤方式、影像学检查结果、自身颈椎退变情况、临床表现、主要诊疗情况、预后情况等,按照损伤与损害后果相关程度分为直接原因、主要原因、同等原因、次要原因、无原因进行伤病关系分析.结果 年龄、致伤方式、颈椎退变及椎管狭窄等是伤病关系分析的重要因素,年龄≤8岁者,一般均认为外伤是损害后果的直接原因,而在其他年龄段,一般均需全面分析上述各种因素,综合评定.结论 综合被鉴定人的年龄、致伤方式、颈椎退变及椎管狭窄等因素,有助于准确分析、判定无骨折脱位型颈脊髓损伤者损伤与损害后果的因果关系.%Objective To explore forensic identification of causality between injury and the consequence in cases of cervical spinal cord injury without fracture or dislocation. Methods Twenty-five cases of cervical spinal cord injury without fracture or dislocation were collected. The age, mode of injury, imaging reports, cervical vertebral degeneration, clinical manifestations, diagnosis, treatment and injury consequences were summarized. The causality between injury and its consequence were classified as direct cause, main cause, same cause, minor cause and no cause. Results Age, mode of injury, cervical vertebral degeneration and spinal stenosis were important factors in the analysis of causality. In the injured younger than 8-year-old trauma was generally the direct cause to the damage. While in other injured, it was needed to analyze the various factors comprehensively. Conclusion Comprehensive analysis of age, mode of injury, cervical vertebral degeneration, spinal stenosis and other factors would contribute to accurate identification of the causality between the injury and the consequences in cases of cervical spinal cord injury without fracture or dislocation.
