The diagnosis and management of cervical spine injury is more complex in children than in adults.
Part I of this series stressed the importance of tailoring the evaluation of cervical spine injuries based on age, mechanism of injury, and physical examination findings. Part II will discuss the role of magnetic resonance imaging (MRI) as well as the management of pediatric cervical spine injuries in the emergency department.
Children have several common variations in their anatomy, such as pseudosubluxation of C2-C3, widening of the atlantodens interval, and ossification centers, that can appear concerning on imaging but are normal. Physicians should be alert for signs or symptoms of atlantorotary subluxation and spinal cord injury without radiologic abnormality when treating children with spinal cord injury, as these conditions have significant morbidity. MRI can identify injuries to the spinal cord that are not apparent with other modalities, and should be used when a child presents with a neurologic deficit but normal X-ray study or CT scan.
With knowledge of these variations in pediatric anatomy, emergency physicians can appropriately identify injuries to the cervical spine and determine when further imaging is needed.
儿童颈椎损伤的诊断和处理比成人更为复杂。
本系列文章的第一部分强调了根据年龄、损伤机制和体格检查结果来调整颈椎损伤评估的重要性。第二部分将讨论磁共振成像(MRI)的作用以及急诊科对儿童颈椎损伤的处理。
儿童在解剖结构上有一些常见的变异,如C2-C3假性半脱位、寰齿间隙增宽和骨化中心,这些在影像学上可能看似异常,但实际上是正常的。在治疗脊髓损伤的儿童时,医生应警惕寰枢椎旋转半脱位和无放射学异常的脊髓损伤的体征或症状,因为这些情况会导致严重的发病率。MRI能够识别其他检查方式无法发现的脊髓损伤,当儿童出现神经功能缺损但X线检查或CT扫描正常时,应使用MRI。
了解儿童解剖结构的这些变异后,急诊医生能够正确识别颈椎损伤,并确定何时需要进一步的影像学检查。
