What is the mechanism of injury for a compression fracture?

The mechanism of injury for a compression fracture primarily involves spinal flexion combined with load or compression forces. In this scenario, when a significant load is applied while the spine is in a flexed position, the vertebrae can become compromised and collapse under the stress, leading to a compression fracture. This type of fracture is particularly common in osteoporotic patients, where weaker bones are more susceptible to sustaining such injuries due to the additional mechanical force during flexion.

In this context, spinal flexion with compression specifically indicates a situation where the body's center of mass shifts forward, causing a compressive force on the spinal column, which can exceed the structural integrity of the vertebrae. As the vertebrae are forced together, it results in a fracture, underscoring the importance of understanding load mechanics in the diagnosis and management of spinal injuries.
