Although computed tomography (CT) is commonly used in addition to plain radiographs to evaluate cervical spinal fractures, it may fail to detect some clinically significant fractures. Cervical spinal fractures were produced in cadavers, studied with CT, and documented by cryomicrotomy. The CT scans were interpreted independent of the anatomic sections. Pedicle and lateral mass fractures were regularly unrecognized on CT scans. In these cases, widening and hemarthrosis of the adjacent facet joints were evident. A widened facet joint is an indirect sign of an occult cervical spinal fracture.
尽管计算机断层扫描（CT）通常与普通X线片一起用于评估颈椎骨折，但它可能无法检测到一些具有临床意义的骨折。在尸体上制造颈椎骨折，用CT进行研究，并用冷冻切片记录。CT扫描的解读独立于解剖切片。椎弓根和侧块骨折在CT扫描中经常未被识别。在这些病例中，相邻小关节的增宽和积血很明显。小关节增宽是隐匿性颈椎骨折的间接征象。
