Chance Fractures of the Spine - Everything You Need To Know - Dr. Nabil Ebraheim

Dr. Ebraheim’s educational animated video describing the mechanism of injury involving chance fractures of the spine.
A head-on collision would cause the person wearing a lap belt to suddenly flex his spine at the waist, creating severe stress on the posterior elements of the vertebra.
Known as seat-belt fractures, chance fractures are flexion distraction injuries that can occur when there is acute hyperflexion of the back. Fracture occurs around a fixed point in the spine.
Chance fractures are less associated with motor vehicle accidents after shoulder and lap belts were installed. These fractures probably result more from falls or crush injuries.
Types of chance fractures:
1-Bony chance
Bony injuries could heal with immobilization, casting or bracing.
2-Ligamentous chance
With ligamentous chance injury, the soft tissues and ligaments don’t heal and require surgery.
Chance fractures typically are a three column injury with a horizontal orientation of the fracture.
These fractures most commonly occur at the level of T12, L1, L2, also known as the thoracolumbar spine. This injury is not associated with neurological deficits.
Obtain CT scan of the abdomen because this injury is associated with intra-abdominal injuries.
