2. Neurologic injury

Neurologic status at the moment of admission should be scored according to the following scheme:

N0: Neurologically intact

N1: Transient neurologic deficit, which is no longer present

N2: Radicular symptoms

N3: Incomplete spinal cord injury or any degree of cauda equina injury

N4: Complete spinal cord injury

NX: Neurologic status is unknown due to sedation or head injury

3. Modifiers

There are two modifiers, which can be used in addition to ad 1 and 2:

M1: This modifier is used to designate fractures with an indeterminate injury to the tension band based on spinal imaging with or without MRI. This modifier is important for designating those injuries with stable injuries from a bony standpoint for which ligamentous insufficiency may help determine whether operative stabilization is a consideration.

M2: is used to designate a patient-specific comorbidity, which might argue either for or against surgery for patients with relative surgical indications. Examples of an M2 modifier include ankylosing spondylitis or burns affecting the skin overlying the injured spine.
