Penetrating Neck Injury.
What we know
The primary driver of these injuries in modern warfare is not the bullet, but the fragment.
Explosive fragmentation — shrapnel from IEDs, artillery, grenades, and mortar rounds — accounts for up to 70% of penetrating neck injuries in some combat studies. While gunshot wounds are statistically less common, they are devastatingly more lethal, carrying an approximate mortality rate of 78% compared to 41% for fragment wounds.
In both cases, death is most commonly caused by catastrophic vascular injury. Major vessel damage to the carotid artery or internal jugular vein accounts for 85% of deaths resulting from explosive fragmentation alone — vessels that, once severed or torn, offer almost no margin of time for surgical rescue on the battlefield.
The clinical picture of a severe PNI is one of cascading, compounding emergencies. Active hemorrhage, expanding hematomas, airway obstruction, and tension pneumothorax can develop simultaneously, each individually life-threatening. Surgeons operating in combat surgical facilities work to a simple rule: any "hard sign" — visible bleeding, a rapidly expanding neck, a compromised airway, or a patient in shock — demands immediate operative intervention. There is little room for hesitation. For stable patients, Computed Tomography Angiography (CTA) has proven highly effective at identifying or ruling out significant injury, but the chaotic reality of combat casualty care often precludes such measured assessment.
For those who survive the initial wound, the ordeal is far from over. Long-term complications including vocal cord paralysis, tracheal stenosis, and dysphagia are well documented among PNI survivors, leaving many with permanent and life-altering damage. Compounding the tragedy is the question of prevention. Standard-issue neck collars, such as the UK OSPREY system, offer meaningful fragment protection to Zones I and II of the neck — yet studies indicate that in 58% of cases, personnel chose not to wear them. In a wound pattern where the margin between life and death is measured in millimetres and seconds, that decision carries consequences that the data makes painfully clear.
