Penetrating neck trauma is a serious cause of morbidity and mortality in the acutely injured patient. While a "no-zone" management approach to penetrating neck injuries is replacing the traditional three zone approach, knowledge of neck zone anatomy is crucial to anticipating and diagnosing pathology inherent to each zone. Zone I is the most caudal and includes the base of the neck and thoracic inlet.
Ankle sprains are one of the most common traumatic injuries encountered in the Emergency Department. The pathophysiology of an ankle sprain occurs when there is abnormal movement of the talus within the ankle mortise leading to disruption of the surrounding ligaments.
