What is the Ottawa Ankle Rule?
The Ottawa Ankle Rules is a decision tool used to determine whether x-ray is needed for patients with acute ankle injuries. The rule was first published in 1992, and has been validated in several studies.
To use the Ottawa Ankle Rule, the following three questions must be answered:
1. Is there any pain in the malleolar zone?
2. Is the bone tenderness present on examination by palpation of either the medial or lateral malleolus?
3. Can the patient walk four steps both immediately and at four hours after the injury without pain or limping?
If the answer to all three questions is “no,” then x-ray is not needed.
How does the Ottawa Ankle Rule work?
The Ottawa Ankle Rule is a clinical decision tool that can help determine whether or not an X-ray is needed for a suspected ankle or foot injury. The basic principle behind the rule is that if you can’t bear weight on your injured foot or ankle, it’s likely that you have a fracture and you’ll need an X-ray to confirm the diagnosis.
The Ottawa Ankle Rule was first developed in 1992 by a team of Canadian researchers and has since been validated in several studies. It’s considered to be more than 95% accurate in ruling out fractures, which means that there’s only a 5% chance that an X-ray will be needed if the Ottawa Ankle Rule is used.
Here’s how it works:
1. The patient is asked to rate their pain on a scale of 0 to 10, with 10 being the worst pain imaginable.
2. The clinician then palpates (examines by touch) each of the bony points around the ankle and foot to see if there is tenderness. These bony points are known as the malleoli (the two bony prominences on either side of the ankle), the base of thefifth metatarsal (at the back of the foot), and the navicular bone (on top of the foot).
3. If there is any tenderness at any of these bony points, an X-ray is automatically ordered.
4. If there is no tenderness at these bony points, the clinician then asks the patient to stand on their injured foot and look for pain or inability to weight bear.
5. If there is pain or inability to weight bear, an X-ray is ordered.
6. If there is no pain or inability to weight bear, no X-ray is needed and further management will focus on conservative treatment such as rest, ice, compression, and elevation (RICE).
When should the Ottawa Ankle Rule be used?
The Ottawa Ankle Rules should be used to determine if an x-ray is needed for a patient with foot or ankle pain. The rules can also be used for children, but the parameters for deciding when an x-ray is needed are different.
There are two Ottawa Ankle Rules:
1. The first rule is used to decide if an x-ray is needed for patients over the age of 18 years with acute foot or ankle pain.
2. The second rule is used to decide if an x-ray is needed for patients under the age of 18 years with acute foot or ankle pain.
Who developed the Ottawa Ankle Rule?
The Ottawa Ankle Rules were first published in 1992 by a team of researchers at the University of Ottawa, in Ontario, Canada. The rules were developed to help doctors and other healthcare professionals decide whether or not a child or adult needed an X-ray of their ankle after sustaining an injury.
What are the benefits of using the Ottawa Ankle Rule?
There are many benefits to using the Ottawa Ankle Rule, including:
– Reduced costs: fewer unnecessary x-rays and follow-up appointments
– Reduced radiation exposure: helps to lower your risk of developing cancer
– Lower risk of misdiagnosis: the Ottawa Ankle Rule is very accurate in ruling out fractures, so you don’t have to worry about missing a serious injury
– Quicker diagnosis and treatment: the faster you can get the right diagnosis, the sooner you can start treatment and begin your road to recovery
