Is spinal immobilisation necessary for all patients sustaining isolated penetrating trauma?
Introduction
It has been suggested that full spinal immobilisation is rarely, if ever, required for patients with isolated penetrating trauma [2], [6]. The advanced trauma life support (ATLS®) student manual does not make the distinction between blunt and penetrating trauma with regard to spinal injury [1]. It emphasises the need for full and continuous spinal immobilisation in any patient with a suspected spinal cord or column injury until a fracture has been excluded radiologically. This refers predominantly to blunt trauma of the spinal cord and spinal column.
This approach has significant implications for pre-hospital care. Time may be a crucial factor in determining outcome in severe penetrating trauma. In critically injured patients, it has been estimated that for every 10 min of delay in definitive treatment, survival drops by 10% [7]. Therefore, in this study we aimed to determine if there were any mechanically unstable or potentially mechanically unstable spinal column injuries requiring formal spinal immobilisation in isolated penetrating trauma patients in Scotland. We also examined the incidence of spinal cord injury due to penetrating trauma in Scotland.

Methods
The Scottish Trauma Audit Group (STAG) was established in 1991 to evaluate the management of major trauma in individual Scottish hospitals [3]. It utilises TRISS methodology, which combines the injury severity score (ISS) and the revised trauma score (RTS) in addition to the patient’s age, to generate a probability of survival for each patient. [4] Currently 25 hospitals contribute to the national database. At the time of writing, data had been collected prospectively on more than 35,000
Results
There were 34,903 trauma patients available for study; 32,974 (94.5%) had sustained blunt trauma and 1929 (5.5%) penetrating trauma. Twenty-seven patients were coded as having penetrating trauma and concurrent spinal injury. Fifteen patients were excluded either because initial review clearly showed that there was a major blunt mechanism of injury also coded which unequivocally caused the spinal trauma, or because the spinal component of the injury was trivial. Patients were also excluded if
Discussion
In 1929 cases of penetrating trauma, the only patients with spinal cord lesions had clear evidence of this at initial presentation or were in cardiorespiratory arrest. This suggests that spinal column or spinal cord injury resulting from isolated penetrating trauma can be excluded in fully conscious patients without neurological symptoms or signs at presentation.
Contemporary teaching on trauma does not make any distinction between blunt and penetrating trauma in terms of the need for full

Assessing attitudes toward spinal immobilization
2013, Journal of Emergency MedicineCitation Excerpt :Advanced airway management procedures, including endotracheal intubation, are more likely to fail when cervical spinal immobilization is in place (3). Additionally, patients with spinal injury from isolated penetrating trauma are often distinguishable by the concurrence of neurological deficit or traumatic arrest (4). The NEXUS trial indicated that clinically significant cervical spine injuries cannot be effectively excluded in patients presenting with posterior midline cervical spinal tenderness, focal neurologic deficit, concurrent intoxication, altered level of consciousness, or painful distracting injuries (5).
Initial Management of the Patient With Cervical Spine Injury
2013, Seminars in Spine SurgeryCitation Excerpt :It is estimated that approximately 3%-25% of spinal cord injuries are incurred after the initial impact, the majority due to inappropriate prehospital management.8,9 Spine immobilization is not recommended in patients with penetrating trauma, as the brace might obscure early diagnosis of other life-threatening injuries.10,11 According to the American College of Surgeons,12 spine immobilization should be done on a hard backboard using a rigid cervical collar (Fig. 2), lateral support devices, and tape or straps to secure the patient at the forehead, thorax, and extremities, and to secure the lateral support devices to the backboard.
