Neurologic outcomes were correlated with the cervical canal diameter for 33 patients who sustained unilateral or bilateral facet fractures, dislocations, subluxations, or perch injuries during a 9-year period. Lateral roentgenograms (target distance, 72 in.) were used to measure the canal and calculate the canal-body ratio (Torg's ratio) at the level of the vertebral injury. Frankel's classification system was employed to compare initial and final neurologic function. The most important factors that determined the long-term functional results after unilateral or bilateral injuries in the cervical spine were the degree of vertebral trauma and the severity of the initial neurologic deficit. There was no correlation between the preinjury canal diameter or ratio and the severity of neurologic injury or the prognosis. Also, neurologic injuries were more common and more severe in patients with bilateral facet injuries. No patients with complete injuries had an improvement in their Frankel grade.
对33例在9年期间发生单侧或双侧小关节骨折、脱位、半脱位或不稳损伤的患者，将神经学转归与颈椎管直径进行了相关性分析。使用侧位X线片（靶距离72英寸）测量椎管，并计算损伤椎体水平的椎管与椎体比值（Torg比值）。采用Frankel分级系统比较初始和最终的神经功能。决定颈椎单侧或双侧损伤后长期功能结果的最重要因素是椎体创伤程度和初始神经功能缺损的严重程度。伤前椎管直径或比值与神经损伤严重程度或预后之间无相关性。此外，双侧小关节损伤患者的神经损伤更常见且更严重。完全损伤的患者Frankel分级均无改善。
