Question 12

Hyperflexion of the cervical region during a head-on collision could result in——–

Answer 12

rupture of lower cervical intervertebral discs (e.g. C5/C6 & C6/C7) resulting in compression of spinal roots C6 and C7; pain is felt in the neck, shoulder, arm and hand

Question 13

whiplash injury

Answer 13

Severe hyperextension of the neck and hyperflexation lead to ould result tearing of anterior and posterior longitudinal ligaments, fracture of the cervical spinous processes, disc rupture, neck muscles and blood vessel injuries could result.
