What injury can occur when a horizontal force is applied to one section of the spine?

• A. Compression fracture
• B. Shearing injury
• C. Distraction injury
• D. Flexion injury

Answer: (B)

A shearing injury occurs when a horizontal force is applied to one section of the spine, as this type of force can cause adjacent vertebrae to slide past one another. This sliding action stresses the vertebral column and can result in misalignment or damage to the spinal structures, such as ligaments and disks.

Shearing injuries often happen during trauma events like vehicular accidents or falls, where the force applied is strong and directed laterally. This mechanism is distinct because it affects the spine's stability and alignment rather than compressing or pulling it apart, which is the focus of other types of injuries. Understanding this mechanism is crucial for diagnosing and treating spinal injuries effectively.
