Prospective evaluation of ottawa ankle rules in acute ankle injury

Acute ankle injuries are one of the most common reasons for presenting to emergency departments. These patients are almost always routinely referred for radiography, whereas less than 15% have clinically significant fractures. The Ottawa Ankle Rules (OARs) have been designed to reduce the number...
