Figure A and B show a traumatic C5-C6 fracture dislocation, which can result in Brown-Sequard syndrome. Brown-Sequard syndrome is defined as a unilateral cord injury with ipsilateral motor deficit and loss of contralateral pain and temperature recognition. Half of the spinal cord is typically damaged, and the loss of pain and temperature sensation usually occurs two levels below the insult. This injury, which is usually result of penetrating trauma, has the best prognosis of all the spinal cord injury syndromes. Illustration A outlines the anatomy of Brown-Sequard syndrome.
