INTRODUCTION
From the Revolutionary War to the settling of our western frontier, small-arms use has been inextricably entwined with American history. Widespread use of firearms has induced scientists and physicians to define the basic principles of wound ballistics. Over the past century, the mechanisms by which penetrating projectiles injure living tissue have been extensively studied and explained. Yet mistaken ideas about bullet effects are still held today. The most common misconception about gunshot
CONTROVERSIES REGARDING WOUNDING POTENTIAL
In 1967, a group reported the wounds caused by M-16 rifle bullets in Vietnam as "massively destructive"1 and possessing "devastating wounding power . . . tremendous wounding and killing power".2 Because the 3,100 foot/second (945 m/second) muzzle velocity of the M-16 bullet was higher than that of previous military bullets, "high velocity" became synonymous with "devastating wounding power."
These subjective descriptions attracted the attention of Swedish researchers.3 In 1974, a Swedish
WOUNDING MECHANISMS
The objective measurement of a wound's dimensions, along with a clear and precise description of the tissue disruption (augmented by good-quality photographs including a measuring scale) is the only valid method of verifying the disruption caused by a given bullet. This method permits meaningful comparison of the disruptive effects caused by various bullets.10
Basic physics verifies that a projectile's potential to disrupt tissue is determined by both its mass and its velocity. Wounding
COMMUNICATION PROBLEMS IN WOUND BALLISTICS
Failure to adhere to the basic precepts of scientific method is the common denominator of misconceptions in wound ballistics.41 Good science is impossible without precise and clear communication, but the authors of most papers appearing in the wound-ballistics literature continue to use terms that are the antithesis of precision and clarity. These include the following.
High velocity The British draw their line between low and high velocity at 1,100 feet/second (335 m/second), which is the speed
PATHOPHYSIOLOGY OF GUNSHOT WOUND TREATMENT
There is little disagreement in the wound-ballistics literature about how to treat penetrating projectile wounds of the chest and abdomen or those that disrupt major blood vessels or bones. Ironically, most of the dispute and misunderstanding concerns treatment of the least lethal injuries: uncomplicated extremity wounds. Central to this dispute is how to manage the soft-tissue disruption.
Knowledge of the pathophysiology of penetrating projectile wounds is needed to choose the best treatment
