What is the main goal of spinal immobilization in field evacuation?

• A. Protect the cervical spine and prevent worsening neurologic injury during movement
• B. Immobilize all limbs to minimize pain
• C. Improve overall circulation
• D. Prevent infection at wound sites

Answer: (B)

Movement during field evacuation can worsen a spinal injury by causing displacement or compression of the vertebrae and spinal cord. The main goal of immobilization is to prevent that secondary damage by keeping the spine in a neutral, aligned position and limiting movement during transport, especially for the cervical spine which is most vulnerable to injury with even small motions. Using a cervical collar and securing the patient to a backboard or scoop stretcher helps maintain alignment during transfers and loading into vehicles or aircraft, reducing the risk of expanding any spinal injury and preserving neurologic function. This focus is distinct from immobilizing limbs to reduce pain, improving circulation, or preventing infection—those are addressed by other aspects of care, while spinal immobilization specifically aims to protect the spinal cord during movement.
