Sub-axial Cervical Spine Injury Classification System (SLICS)

The Subaxial Cervical Spine Injury Classification (SLIC) system is a classification system for subaxial cervical spine trauma that helps determine information about injury pattern and severity, in addition to treatment considerations and prognosis. [1]
