Cervical Cord and Nerve Root Injuries-Etiology
- 5 basic MOI's:
- 1. laceration: caused by a dislocation or fx. Bony fragments may cut and tear nerve roots or the spinal cord causing varying degrees of paralysis
- 2. cervical cord and nerve root injuries: caused from dislocations and fx's. Seldom causing problems but could if the hemorrhage is within the spinal cord itself
- 3. Contusion: may result from a sudden displacement of a vertebrae that compresses the cord or nerve root then returns to normal position. May cause temporary or permanent damage
- 4. Cervical cord neuropraxia: a severe twise or snap of the neck may cause temporary numbness, tingling and paralysis. After a short while normal function will return. Usually caused by cervical spine stenosis.
- 5. Spinal cord shock: seen with severe trauma to the spinal cord, usually a cord transaction. Immediate loss of function below injured site.
