Prehospital Cervical Spine Motion: Immobilization Versus Spine Motion Restriction

Area of Science:

• Emergency Medicine
• Orthopedics
• Biomechanics

Background:

• Cervical spine immobilization is crucial in prehospital trauma care to prevent secondary injury.
• Traditional spinal immobilization (TSI) techniques are widely used but associated with potential complications.
• Alternative methods like spinal motion restriction (SMR) require rigorous evaluation.

Purpose of the Study:

• To compare the efficacy of traditional spinal immobilization (TSI) and spinal motion restriction (SMR) on cervical spine movement.
• To assess cervical spine motion, vital signs, and pain during simulated prehospital ground transport.
• To evaluate SMR as a potential alternative to TSI in prehospital settings.

Main Methods:

• A counterbalanced crossover design was employed with 20 healthy male volunteers.
• Participants underwent simulated ambulance transport under both TSI and SMR conditions.
• Cervical spine motion (cumulative integrated and peak range), vital signs, and pain were measured.

Main Results:

• Greater transverse plane motion occurred during TSI compared to SMR (P=0.049).
• Increased transverse peak range of motion was observed during loading/unloading with TSI (P<0.001).
• Pain was reported by 40% with TSI versus 25% with SMR (P=0.453).

Conclusions:

• Spinal motion restriction (SMR) controls cervical motion as effectively as traditional spinal immobilization (TSI).
• SMR is supported as a safe and effective alternative to TSI, considering potential complications of TSI.
• Further research with actual patient populations is recommended to validate these findings.
