Ballistic trauma is a sad and tragic part of everyday life in many parts of the world, from South Africa to Palestine, from Afghanistan to the United States. Yet the perceived glamour of the gunshot wound lures many students to undertake an elective in trauma surgery. Here we explore the basics of ballistic trauma.
Firearms are weapons that require an additional source of energy, usually provided by the ignition of a propellant to fire a projectile--for example, bullets or pellets. Firearms are classically divided into four groups (see box). When a firearm is discharged, a cloud of vapour (gas) and particulate matter (solid) is deposited nearby, on skin and clothes for example. Explosives--such as bombs and hand grenades--behave in a similar manner.
Box 1: Four types of firearm
– Handguns--pistols, revolvers
– High velocity assault rifles--AK47
Smooth bore firearms--shotguns
Modified firearms--release tear gas, rubber bullets
Handguns and rifles are rifled firearms. In both, the barrel of the weapon is grooved, causing the bullet to twist when fired; the shooter experiences less recoil and can take a more accurate shot. The range (the distance between the muzzle of the weapon and the victim) can be determined by close examination of the entrance wound.
Smooth bore firearms
Smooth bore firearms--the commonest example of which is a shotgun--are weapons in which the barrel is simply a tube. The cartridge for smooth bore firearms is also quite distinctive--releasing between seven hundred and six hundred pellets depending on the type of shotgun.
“Homemade firearms” is a term which covers many weapons. Their variability accounts for a range of unpredictable injuries. However, they have become …
