A functional rotatory computed tomography (CT) study of 423 whiplash patients with cervical spine soft-tissue injury was undertaken to determine its diagnostic value. The results are correlated with previous CT studies on normal subjects, and an evaluation of paradox motion, in which the lower vertebra rotates more than the vertebra immediately superior to it, is given. Asymmetrical left/right rotation reached the pathological value in 36% of the patient population at the level of C0-1. Twice as many patients had hypermobile rotation to the left as compared with the right, perhaps indicating that the right alar ligament is more often damaged in injuries involving the whiplash mechanism. A higher percentage of pathological values for hypermobile rotation was found at the level of C0-1 than at C1-2. Patients exhibiting paradox rotation had a significantly higher amount of rotation to the contralateral side than did those who exhibited no paradox rotation. These findings validate the use of functional rotatory CT in the evaluation of soft-tissue damage of the upper cervical spine resulting from whiplash injury.
对423例颈椎软组织损伤的挥鞭样损伤患者进行了功能性旋转计算机断层扫描（CT）研究，以确定其诊断价值。将结果与先前对正常受试者的CT研究进行了相关性分析，并对反常运动进行了评估，即下一节椎体的旋转角度大于紧邻其上的椎体。在C0-1水平，36%的患者出现不对称左右旋转，达到病理值。向左旋转过度的患者数量是向右的两倍，这可能表明在涉及挥鞭样损伤机制的损伤中，右侧翼状韧带更常受损。C0-1水平的旋转过度的病理值百分比高于C1-2水平。出现反常旋转的患者向对侧的旋转量明显高于未出现反常旋转的患者。这些发现证实了功能性旋转CT在评估挥鞭样损伤导致的上颈椎软组织损伤中的应用价值。
