While on spring break in Johannesburg, Jason was involved in a motorcycle accident. In the accident he was thrown from his pike to the pavement, landing on his back. A police officer witnessed the accident and immediately called for medical assistance. Emergency personnel arrived within minutes, and upon recognizing the seriousness of Jason's back injury, immobilized his neck and secured him to a rigid board prior to transporting him to the emergency room of the nearest hospital. When he arrived at the hospital, Jason was conscious and complained of pain in his lower back. Upon examination by the emergency room personnel, Jason was found to have numerous abrasions and contusions, and loss of both sensation and motor control of his legs. After he was stabilized, a complete neurological exam was performed to assess and localize Jason's injury. The neurological exam…arrow_forward
