![]() Individuals must stimulate it by repetitively practicing weakened movements. However, neuroplasticity doesn’t work on its own. The less severe a spinal cord injury is, the more spared neural pathways exist, and the better the recovery outlook. Neuroplasticity is the central nervous system’s ability to reorganize itself so that functions impaired by damage to a part of the central nervous system can potentially be relearned. Spared neural pathways play an essential role in determining rehabilitative outcomes after a C5 SCI because they are capable of neuroplasticity. As a result, some C5 SCI patients may be able to move and feel areas innervated below their level of injury, although these movements may be very weak. In contrast, an incomplete C5 spinal cord injury does not transect the entire spinal cord, thus spared neural pathways still exist. In other words, there are no pathways to connect messages between the brain and areas below the level of injury. Individuals with a complete C5 spinal cord injury will have no sensation or control over movements below their level of injury because no spared neural pathways exist. It’s essential to understand the differences between the two because they have different functional implications and prognosis. Loss of positioning sense due to disruption of dorsal columns.Spinal cord injuries are classified as complete or incomplete.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.
