Whiplash Associated Soft Tissue Injuries

Such whiplash injuries are one of the most common injuries with car accidents. Often X-rays, bone scans, CT and MRI scans do not show any abnormality although clinically there can be a very disabling condition. Most of the time it is best to not use any collars, but to remobilize early provided that more serious injuries like fractures or serious unstable ligamentous injuries have been ruled out by the treating physician (Ref. 1).

Apart from car accidents the cervical spine is target for many other injuries such as sports injuries, work injuries, personal injuries and mishaps at home.

The mass of the head, which is supported by the neck, generates a powerful force that can be easily transmitted to the lower end of the cervical spine where most of the impact is felt.

Due to the leverage of the length of the cervical spine this force is magnified and transmitted to the structures there resulting in cervical spine injury. The end results are facet joint subluxations, ligamentous tears, strains (also known as neck strain) and compression fractures of the spine (mostly at the upper and lower end of the cervical spine). When a heavy object falls onto the head, this often will lead to compression fractures of one or more of the vertebral bodies of the cervical spine. In the past no help was available for this, but as the link shows kyphoplasty can be offered in suitable cases today. When the force strikes more from the side of the vertebral body an end plate fracture may occur as shown here.
