研究设计.回顾性审查。目的评价不同程度创伤力的静态压迫因素和动态因素对后纵韧带骨化患者颈脊髓损伤（SCI）的影响。背景资料总结。脊髓疾病的发生是由于各种因素，包括静态因素和创伤力。因此，关于脊髓损伤导致瘫痪的严重程度的讨论必须集中在基于创伤力的动态因素以及静态压缩因素上。然而，以往的文献报道并没有详细描述创伤力的影响。本研究纳入了50例伴有后纵韧带骨化的颈椎脊髓损伤患者。观察伤后3 d美国脊髓损伤协会运动评分、创伤力大小、脊髓受压率，并分析各因素之间的关系。受伤时的瘫痪不能仅由静态因素或仅由创伤力决定。损伤时瘫痪的严重程度是根据静态因素和创伤力的程度来确定的。脊髓压迫程度和创伤力的程度被认为是与颈椎后纵韧带骨化症患者的严重程度相关的重要因素。
Study Design. Retrospective review.Objective. To evaluate the influence of static compression factors and dynamic factors based on the various degrees of traumatic force on the cervical spinal cord injury (SCI) in patients with ossification of the posterior longitudinal ligament.Summary of Background Data. Spinal cord disorder occurs as a result of various factors, including static factors and traumatic force. Discussions about the severity of paralysis resulting from SCI must therefore focus on dynamic factors based on the traumatic force as well as on static compression factors. However, the past reports did not describe the influence of traumatic force in detail.Methods. Fifty patients presenting with cervical SCI associated with ossification of the posterior longitudinal ligament were included in this study. The American Spinal Injury Association motor score 3 days after injury, the degree of the traumatic force, and the spinal cord compression rate were investigated, and the relationships among these factors were investigated.Results. Paralysis at the time of injury was not determined by static factors alone or by traumatic force alone. The severity of paralysis at the time of injury was determined on the basis of a combination of both the static factors and the degree of traumatic force.Conclusion. Both the degree of spinal cord compression and the degree of traumatic force were found to be important factors associated with the severity of cervical SCI in patients with ossification of the posterior longitudinal ligament.
