Greater than 12 million traumatic lacerations are treated every year in emergency departments (EDs) across the United States. 1 Extremities provide most of the interaction with the environment and are therefore particularly prone to injury.

Wounds may be caused by sharp or blunt mechanisms; each has different implications for evaluation and treatment ( T§ble...,4.Q.:l). Blunt-force wounds often have edges that are irregular and difficult to close; they are also more likely to contain an underlying fracture and are more susceptible to infection than wounds caused by sharp forces.2 Contamination by soil, chemicals, and foreign bodies can adversely affect the outcome of any laceration, increasing the risks of infection and scarring and slowing the healing process. A more detailed discussion of hand and digit injuries can be found in Chapter.,260.
