A hangman's fracture is primarily caused by what type of injury?

1. Hyper-flexion of the neck

2. Hyper-extension of the neck

3. Compression of the spine

4. Rotational forces on the spine

The correct answer is: Hyper-extension of the neck

A hangman's fracture, also known as traumatic spondylolisthesis of the second cervical vertebra, is primarily associated with hyper-extension of the neck. This type of injury typically occurs when there is a significant backward bending of the neck, which can result from mechanisms such as car accidents, falls, or hanging. The hyper-extension places excessive strain on the cervical spine, particularly at the junction between the first and second cervical vertebrae, leading to fractures. This fracture is often characterized by the displacement of the vertebrae and potential damage to the spinal cord, making it a serious condition that requires immediate medical attention. Understanding the mechanism of injury is crucial for prevention and management strategies in cases involving high-risk activities or accident-prone scenarios.
