You know that the Ottawa ankle rules are applicable in adult patients and you wonder whether they are applicable in children too.

Comment(s)
Apart from Chande's study, the other studies did not examine all patients with radiography. Therefore, fractures might be missed by the Ottawa ankle rules and unidentified because of the design of the study. It is anticipated that application of the Ottawa ankle rules in preschool children is difficult as the rules rely on their ability to report tenderness. However, the number of preschool children included in all these studies was small. Hence the role of the Ottawa ankle rules in small children is not yet answered.
Clinical bottom line
More work is required to determine if the Ottawa rules are applicable in children. Early results suggest that they will.
