Spinal Motion Restriction Decisions

Why This Is Hard

Full spinal immobilization on longboards for every “possible” trauma was traditional. Modern EMS education favors selective spinal motion restriction (SMR): protect patients who need it, avoid harming those who do not. Protocols differ — know yours.

Risk Themes (Education)

• High-risk mechanism (e.g., axial load, high-speed MVC, fall from height) plus unreliable exam.
• Midline spinal pain/tenderness, neurologic deficits, altered mentation, intoxication, distracting injury.
• Age and baseline frailty may change thresholds in some protocols.

What SMR Often Looks Like Now

• C-collar when indicated plus secure movement on a stretcher with minimal spinal twisting.
• Longboards as extrication tools more than transport devices in many systems.
• Padding and comfort to reduce pain-related movement.
• Helmet removal decisions per training when airway access requires it.

Key Points for Paramedics

• SMR is not “do nothing” — it is intentional protection matched to risk.
• Boards cause pain, respiratory restriction, and pressure injury with time.
• Unstable multi-system trauma may need packaging compromises — document why.
• Always reassess neuro status after extrication.

Field Pitfalls

• Strapping a walking, low-risk patient to a board “because mechanism.”
• Forgetting airway access under a collar/helmet.
• Rough handling after collar placement.

Practice

Apply your protocol’s decision aid to three vignettes (clear vs high-risk vs unreliable exam). Related: TBI basics.
