Which combination of signs indicates a need for spinal immobilization in a trauma patient?

• A. Neurologic deficit, midline tenderness, distracting injury.
• B. Bruising on arm only.
• C. Stable vitals with no injury.
• D. No signs of trauma.

Answer: (A)

Spinal immobilization is indicated when signs point to possible injury to the spine or spinal cord, and you want to prevent any movement that could worsen that injury. The combination of neurologic deficit (such as weakness, numbness, or loss of function), midline tenderness along the spine, and a distracting injury (another serious injury that could mask spinal injury) strongest suggests a spinal insult is present and warrants immobilization. Midline tenderness shows the spine itself could be injured. A neurologic deficit indicates potential cord involvement. A distracting injury means you can’t rely on the other injuries to rule out spine injury, so protecting the spine is prudent. The other options—arm bruising alone, stable vitals with no injury, or no signs of trauma—do not by themselves point to a spine injury requiring immobilization, so they aren’t as strong indicators.
