Cervical Spine Trauma Management

Classification and Severity Assessment

• The Subaxial Injury Classification (SLIC) System provides level I evidence with excellent reliability and class I recommendations for grading instability and fracture patterns in patients with cervical spinal traumatic injury, as recommended by the American Association of Neurological Surgeons 1, 2, 3, 4
• Discoligamentous Complex (DLC) Integrity is evaluated in the SLIC system, with disrupted DLC assigned 2 points 2
• Neurological Status is incorporated into the SLIC system, with complete cord injury assigned 2 points and incomplete cord injury assigned 3 points 4

Treatment Decision-Making

• A SLIC score of ≥5 is recommended for surgical intervention, as guided by the SLIC system 1
• The SLIC system assists clinicians in managing complex cervical fracture-dislocation injuries by providing guidance on the need for decompression, realignment, and stabilization 1, 2, 3

Clinical Significance and Implementation

• The SLIC system overcomes limitations of earlier classification systems, demonstrating superior reliability with intraclass correlation coefficients (ICC) ranging between 0.49 and 0.90 1, 2, 3
• Use of the SLIC system can assist in determining whether patients require surgical decompression of the spinal canal and cord, followed by spinal realignment and stabilization 4

Limitations and Cautions

• The SLIC system does not provide specific recommendations for detailed surgical management approaches 1, 2, 3
• The system does not provide specific recommendations for detailed surgical management, including approach selection (anterior, posterior, or combined) 3
• While the system guides the need for surgical intervention, specific treatment strategies remain variable based on fracture pattern, associated characteristics, institutional resources, and surgeon preferences 2
