Document Summary
Acute injury is something that suddenly happens while chronic injury starts with acute and becomes more problematic over time. Every tissue has a failure point (moment of anatomical failure). Discs weakest on back side: bony vertebrae and za joints can be really catastrophic. Most exposed part; therefore most prone to contusions. Carries most of the weight, base of tripod. Most catastrophic injuries take place in the cervical spine because the most vital actions are performed here (i. e. eating, breathing) Bone is smaller compared to lumbar, therefore much easier to break. Also its great range of motion puts it at risk. Spinal cord is thicker in the cervical spine meaning there is less buffer room (cord doesn"t have room to move around) Well protected by muscle, potential for problem is damage to the vertebral artery which runs through the foramen within tp. Two vertebral arteries run through circle of willis which provides blood flow to brain.
