![]() A CT scan is the best test to verify that a fracture is or is not present. It is sometimes difficult to see a non-displaced or minimally displaced fracture or instability, therefore a Computed Tomography (CT) scan is usually ordered. This is most readily appreciated on the open mouth view which shows that the lateral masses of C1 no longer align with the lateral masses of C2, and that the spaces between the peg and the C1 lateral masses are widened. Plain x-rays of the cervical spine are essential to adequately evaluate a cervical fracture and dislocation. One third of injuries occur at the level of C2, and one half of injuries occur at the level of C6 or C7. Most cervical spine fractures occur predominantly at two levels. The ring expands and loses alignment with the adjacent occipital bone above, and C2 below. Up to 17 of patients have a missed or delayed diagnosis of cervical spine injury, with a risk of permanent neurologic deficit after missed injury of 29. Injury to C1(atlas) results in loss of integrity of its ring structure. This page describes typical appearances of some common C-spine fractures. Bones - Cortical outline/Vertebral body heightĬervical spine injuries often have characteristics which depend on the mechanism of injury.Alignment - Anterior/Posterior/Spinolaminar.Look at all views available in a systematic manner.Clinical considerations are of particular importance when assessing appearances of C-spine X-rays.Normal C-spine X-rays do not exclude significant injury pseudo-Jefferson fracture, or pseudospread of the atlas on the axis.
