Radiographic Predictors of Spinal Column Instability After Gunshot Wounds: A Pragmatic Score

Area of Science:

• Neurosurgery
• Orthopedic Surgery
• Trauma Surgery

Background:

• Firearm-related spinal injuries are a significant public health issue in the US.
• Assessing spinal stability after ballistic trauma presents clinical challenges.
• No established scoring system exists for evaluating spinal column gunshot wounds.

Purpose of the Study:

• To introduce and validate the Ballistic Assessment in Spine Trauma (BLAST) score.
• To differentiate stable from unstable ballistic spinal fractures.
• To guide operative stabilization decisions for spinal gunshot wounds.

Main Methods:

• Retrospective chart review of 353 spinal gunshot wounds (GSWs) over 14 years.
• Application of the novel BLAST score to patients with radiographic spinal column injury.
• Comparison of BLAST score performance with existing spinal injury classification systems.

Main Results:

• A BLAST score of 6 or higher correlated with the need for operative management.
• The BLAST score demonstrated high accuracy (AUC 0.965 cervical, 0.812 thoracolumbar).
• Reliability metrics (kappa, ICC) indicate good to excellent agreement for the BLAST score.

Conclusions:

• The BLAST score is an efficient and accurate tool for assessing spinal stability after GSWs.
• This pragmatic scoring system aids in distinguishing stable from unstable ballistic spinal injuries.
• The BLAST score can inform surgical decision-making in trauma patients with spinal column GSWs.
