Leg, ankle, and foot injuries.

The emergency provider (EP) must be aware of the anatomy of the leg, ankle, and foot. The varied presentation of common injuries must be recognized as well as the unique presentations of uncommon injuries. The astute EP must rely on a focused history and a precise examination to avoid the pitfalls and missed injuries from an over-reliance on radiographic studies. In some cases, emergent orthopedic consultation is required. Potential complications associated with these injuries must be anticipated and avoided if possible.
