Question 39

Describe the mechanism of a whiplash injury and explain how it affects the cervical vertebrae.

Accepted Answer

A whiplash injury involves a sudden and forceful back-and-forth movement of the head, causing excessive extension and flexion of the cervical vertebrae beyond their normal range of motion.

Answer

A whiplash injury occurs when the cervical vertebrae are directly impacted by a force, resulting in compression or fracture of the vertebrae.

Answer

Degenerative changes in the intervertebral discs of the cervical spine can lead to a whiplash injury due to decreased support and stability.

Answer

Muscle weakness and poor posture can increase the risk of a whiplash injury by making the cervical spine more vulnerable to excessive movement.
