Preserving spinal immobilization during transport is about preventing any movement of the spine when a spinal injury is suspected. The backboard should be removed only in a controlled hospital setting where trained staff can continue spinal precautions, perform definitive assessment, and obtain imaging. This minimizes the risk of unrecognized movement causing injury or worsening injuries during removal. Once the patient is in the hospital, with the proper equipment and personnel, immobilization can be safely discontinued as appropriate.

That’s why the correct condition is to remove immobilization only in hospital. The other options imply removing in the field or based on discomfort or not at all, which increases risk or isn’t aligned with how immobilization is managed in practice.
