Ottawa Ankle Rules
Does this ankle injury require an x-ray?
The Ottawa ankle rules have been validated in adults with 100% Sensitivity.
In children ages 1-15 the Ottawa Ankle rules have been validated with 98-100% Specificity and 36-47% Sensitivity for clinically significant ankle injuries, however other studies have suggested lower sensitivity rates. Clinical judgment should be used in younger children.
