Ottawa Ankle Rules
Use the Ottawa Ankle Rules to determine if an ankle X-ray is needed after injury. A validated clinical decision rule with ~98% sensitivity for fractures.
Ottawa Knee Rules
Apply the Ottawa Knee Rules to determine if a knee X-ray is needed after acute knee injury. ~99% sensitivity for clinically significant fractures. Reduces knee X-rays by over 25% when applied correctly.
