X RAY CERVICAL SPINE NORMAL HOW TO

These discs allow the spine to move freely and act as shock absorbers during activity.Īttached to the back of each vertebral body is an arch of bone that forms a continuous hollow longitudinal space, which runs the whole length of the back. The cervical spine (neck region) consists of seven bones ( C1-C7 vertebrae), which are separated from one another by intervertebral discs. Upper extremity deficit is greater than lower extremity deficit, because the lower extremity corticospinal tracts are located lateral in the cord.The neck is part of a long flexible column, known as the spinal column or backbone, which extends through most of the body.Frequently found in elderly with underlying spondylosis or younger people with severe extension injury (figure).It is unstable and is associated with a high incidence of cord damage. Flexion teardrop farcture is the result of extreme flection with axial loading.BID is unstable and is associated with a high incidence of cord damage. Bilateral interfacet dislocation is the result of extreme flection.Unilateral interfacet dislocation is due to both flexion and rotation.Unstable wedge fracture is an unstable flexion injury due to damage to both the anterior column (anterior wedge fracture) as the posterior column (interspinous ligament).Increased concavity along with increased density due to bony impaction. Simple wedge fracture is the result of a pure flexion injury.Since the anterior and middle columns remain intact, this fracture is stable. Anterior subluxation occurs when the posterior ligaments rupture.The most common fracture mechanism in cervical injuries is hyperflexion.

Hyperextension with superimposed spondylosis.

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. 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%. This review is based on a presentation given by Adam Flanders and adapted for the Radiology Assistant by Robin Smithuis.Īpproximately 3 % of patients who present to the emergency department as the result of a motor vehicle accident or fall have a major injury to the cervical spine.ġ0-20% patients with head injury also have a cervical spine injury.
