We developed a computer model to assess the effect of CS management strategies on outcomes in comatose, blunt trauma patients with extremity movement and a negative CS CT scan. Strategies include early collar removal (ECR), ECR &amp; MRI, late collar removal (LCR), and LCR &amp; MRI. MRI risks include hypoxia, hypotension, increased intracranial pressure (\u2191ICP), and ventilator-associated pneumonia (VAP). LCR risks include \u2191ICP, VAP, and delirium. Model elements include Quadriplegia and Primary, Secondary, LCR, and MRI Brain Injury. The Monte Carlo simulation determines health outcomes (Functional Survival versus Quadriplegia, Severe Brain Disability, or Dead). Utility values are Functional Survival 0.90, Quadriplegia 0.20, Severe Brain Disability 0.10, and Dead 0.00. Years of life expectancy are Functional Survival 39.5, Quadriplegia 20.0, Severe Brain Disability 20.0, and Dead 0.0.\n                    <jats:italic toggle=\"yes\">Unstable CS rate 2.5%:<\/jats:italic>\n                    Functional Survival\/1,000:\n                    <jats:italic toggle=\"yes\">Unstable Patients:<\/jats:italic>\n                    ECR 384, LCR 350, LCR &amp; MRI 332, ECR &amp; MRI 331;\n                    <jats:italic toggle=\"yes\">High-Risk Patients:<\/jats:italic>\n                    ECR 161, LCR 151, LCR &amp; MRI 140, ECR &amp; MRI 153;\n                    <jats:italic toggle=\"yes\">Stable Patients:<\/jats:italic>\n                    ECR 596, LCR 587, LCR &amp; MRI 573, ECR &amp; MRI 595.

LCR and MRI brain injury results in losses of functional survivorship that exceed those from quadriplegia.
