What is the most likely mechanism of injury for a patient with disruption of multiple spinal ligaments while being neurologically intact?

In the scenario of a patient experiencing disruption of multiple spinal ligaments while remaining neurologically intact, flexion is indeed the most likely mechanism of injury.

Flexion injuries typically involve a forward bending motion of the spine, which can place significant stress on the anterior ligamentous structures while often leaving the spinal cord and neural elements undamaged. The force during such an injury can lead to a failure of the anterior longitudinal ligament and other supportive ligaments surrounding the vertebrae. This mechanism can result in a variety of ligamentous injuries, including those that might occur in the absence of acute neurological deficits, allowing the patient to remain neurologically intact.

Other potential mechanisms like axial load, compression, or extension, while capable of causing injury, would tend to have different implications for neurological status and specific ligamentous structures affected. For instance, axial load injuries often lead to fractures or vertebral body collapse, potentially causing neurological impairment due to fracture fragments or secondary injuries to the spinal cord. Compression typically refers to forces that may also result in vertebral body crush fractures, while extension injuries can cause damage to posterior structures, often leading to different types of deficits or complications. Thus, flexion remains the most fitting answer for this specific case scenario.
