On the left images of a patient who has been in a car accident and complained of neck pain. MR will demonstrate subtle injuries to the soft tissues. On x-rays this can only be suspected when there is angulation or translation Hyperflexion sprain injuries are injuries to the soft tissues of the spine without fracture. Total absence of sensation and motor function caudal to the level of injury. Loss of positioning sense due to disruption of dorsal columns.Uncommon syndrome due to extension injury. Brown-Sequard syndrome may result from rotational injury such as fracture-dislocation or from penetrating trauma such as stab wound.Ipsilateral motor weakness and contralateral sensory deficit due to hemisection of the spinal cord. Presents with immediate paralysis, because the corticospinal tracts are located in the anterior aspect of the spinal cord.burst fracture, flexion tear drop fracture and herniated disk. Upper extremity deficit is greater than lower extremity deficit, because the lower extremity corticospinal tracts are located lateral in the cord.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.You can click on some of the images to get a larger image. In this overview we will discuss the most common cervical spine injuries. 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.
