A fracture or dislocation of a vertebra can cause bone fragments to pinch and damage the spinal nerves or spinal cord. Most spinal fractures occur from car accidents, falls, gunshot, or sports. Injuries can range from relatively mild ligament and muscle strains, to fractures and dislocations of the bony vertebrae, to debilitating spinal cord damage. Depending on how severe your injury is, you may experience pain, difficulty walking, or be unable to move your arms or legs (paralysis). Many fractures heal with conservative treatment; however severe fractures may require surgery to realign the bones.
