Clinician's Corner: Mastering the Ottawa Ankle Rule: What is it?
The Ottawa Ankle Rule (OAR) is a clinical decision-making tool to help guide clinicians’ decision to obtain an ankle radiograph (x-ray) to rule out a clinically significant ankle or foot fracture among patients who have suffered a blunt, traumatic injury (Stiell et al., 1992). The Ottawa Ankle Rule (OAR) carries a 100% sensitivity for ankle or foot fractures (Stiell et al., 1992) and has been validated for use in multiple studies (Sperry et al., 1999; Stiell et al., 1993). Subsequent studies have found that the OAR can be applied to children aged 2–16 years presenting to the emergency department (ED) with similarly high sensitivity (Plint et al., 1999).
