A 17-year old was injured after diving into shallow water. He was transported to the emergency department where imaging indicated he suffered a spinal cord injury. Based on this information, what mechanism likely caused the spinal cord injury?
hyperextension
compression
flexion-rotation
flexion
The Correct Answer is B
Choice A Rationale: hyperextension is when the neck is bent backward beyond its normal range of motion. This can happen in a rear-end collision or a fall on the back of the head.
Choice B Rationale: A spinal cord injury occurs when there is damage to the spinal cord or the surrounding structures, such as the vertebrae, ligaments, or discs. The most common cause of spinal cord injury is trauma, which can result from direct impact, penetration, or excessive force on the spine. Diving into shallow water can cause compression of the spine, which means that the vertebrae are pushed together and squeeze the spinal cord. This can damage the nerve fibers and disrupt the communication between the brain and the body. Compression injuries can affect any part of the spine, but are more common in the cervical and thoracic regions.
Choice C Rationale: flexion-rotation is when the neck is bent and twisted at the same time. This can happen in a sports injury or a violent assault.
Choice D Rationale: This is when the neck is bent forward beyond its normal range of motion. This can cause the posterior part of the vertebral column to compress and fracture, while the anterior part of the spinal cord is stretched and injured. This can happen in a head-on collision or a fall on the face. A flexion-rotation is when the neck is bent and twisted at the same time.

Explanation
Choice A Rationale: Ringing in the ears (tinnitus) is not a common symptom of Bell's Palsy. Bell's Palsy primarily affects facial muscles.
Choice B Rationale: Bilateral pain from the neck upward is not a typical manifestation of Bell's Palsy. Bell's Palsy typically affects one side of the face.
Choice C Rationale: Progressive loss of ability to use all facial muscles is not the usual pattern of Bell's Palsy. It typically presents with sudden unilateral weakness of the face.
Choice D Rationale: Sudden unilateral weakness of the face is a hallmark symptom of Bell's Palsy. This condition often causes weakness or paralysis of the facial muscles on one side of the face, leading to facial drooping.
