DECIDE THE X-RAY WITH THE OTTAWA ANKLE RULES
Open the Ottawa ankle rules before requesting a film. If no rule is positive, an X-ray is not needed.
No paediatric dose is stated in the sources held for this drug.

A rule that says when NOT to image is the useful half. Imaging every twisted joint is how a clinic fills its X-ray list with normal films.
- A negative rule is a reason not to X-ray, not proof there is no fracture - it pooled 97.6% sensitivity, not 100%.
- Bearing weight must be checked at the time of injury AND now; one of the two is not the rule.
- Not validated as a reason to withhold imaging in a limping child - the growth plate fails before the ligament.
