Neurosurg Focus 28 (5):E4, 20101 P atients with PSIs present very complex, multidisciplinary management challenges for military surgeons. Not only can the patient have immediate and delayed life-threatening damage to organs along the path of the projectile, the spinal column and possibly the neurological structures contained within can also, by definition, suffer injury, the severity of which depends on multiple factors. Spinal cord injury from spinal GSWs is more often a complete lesion with a decreased potential for neurological recovery than with closed trauma.
43There are a number of potential surgical indications, the most controversial of which is whether decompressive laminectomy has any effect on neurological recovery. Medical civilian and military literature is replete with opinions for and against the use of surgery.Although missile characteristics such as size, composition and design are important, the major determinant of the destructive ability of a projectile is velocity at impact and thus the kinetic energy imparted to the surrounding tissue.10 Energy is calculated based on mass and velocity as follows: energy = 1/2mv 2 . Therefore, velocity has a significantly greater effect on energy than projectile mass. Object. Penetrating spinal injury (PSI), although an infrequent injury in the civilian population, is not an infrequent injury in military conflicts. Throughout military history, the role of surgery in the treatment of PSI has been controversial. The US is currently involved in 2 military campaigns, the hallmark of both being the widespread use of various explosive devices. The authors reviewed the evidence for or against the use of decompressive laminectomy to treat PSI to provide a triservice (US Army, Navy, and Air Force) consensus and treatment recommendations for military neurosurgeons and spine surgeons.Methods. A US National Library of Medicine PubMed database search that identified all literature dealing with acute management of PSI from military conflicts and civilian urban trauma centers in the post-Vietnam War period was undertaken.Results. Nineteen retrospective case series (11 military and 8 civilian) met the study criteria. Eleven military articles covered a 20-year time span that included 782 patients who suffered either gunshot or blast-related projectile wounds. Four papers included sufficient data that analyzed the effectiveness of surgery compared with nonoperative management, 6 papers concluded that surgery was of no benefit, 2 papers indicated that surgery did have a role, and 3 papers made no comment. Eight civilian articles covered a 9-year time span that included 653 patients with spinal gunshot wounds. Two articles lacked any comparative data because of treatment bias. Two papers concluded that decompressive laminectomy had a beneficial role, 1 paper favored the removal of intracanal bullets between T-12 and L-4, and 5 papers indicated that surgery was of no benefit.Conclusions. Based on the authors' military and civilian PubMed literature search, most of the evidence s...
