What are the Ottawa Ankle Rules?

The Ottawa Ankle Rules are a set of guidelines that help doctors decide whether or not a person with a suspected ankle injury needs an x-ray.

The rules are based on the fact that nearly all fractures involve the bones of the ankle joint (the bones of the lower leg that come together at the ankle), and that fractures of these bones usually cause tenderness when touched over specific areas.

The Ottawa Ankle Rules state that an x-ray is needed if there is bony tenderness in any of the following areas:
– over the ends of the two bones in the lower leg that come together at the ankle (the tibia and fibula),
– over either side of the ankle joint,
– or in the midfoot (where these bones come together with 5 smaller bones to form the arch of the foot).

How do the Ottawa Ankle Rules help to diagnose a fracture?

The Ottawa Ankle Rules are a set of guidelines that help doctors and other health care providers determine whether a person has a fracture in their ankle or foot. The rules are based on the findings of two large studies that looked at how well the symptoms of a fractures corresponded with actual fractures seen on x-rays.

The studies found that certain symptoms were more likely to be present in people who had fractures, and that people with these symptoms were less likely to have fractures if they did not have these symptoms. Based on these findings, the Ottawa Ankle Rules were developed to help doctors make more accurate decisions about whether or not to order x-rays for patients with ankle or foot injuries.

There are three main criteria that doctors look for when using the Ottawa Ankle Rules: pain in the bone, tenderness when pressing on the bone, and swelling around the bone. If a patient has one or more of these signs, then the doctor will order an x-ray to confirm or rule out a fracture. If a patient does not have any of these signs, then an x-ray is usually not necessary.

Although the Ottawa Ankle Rules are generally considered to be accurate, they are not perfect. In some cases, patients with fractures may not have any of the three main symptoms, and in other cases, patients without fractures may have one or more of the symptoms. Therefore, it is important for doctors to use their clinical judgement when deciding whether or not to order an x-ray for a patient with an ankle or foot injury.

What are the limitations of the Ottawa Ankle Rules?

There are several limitations to the Ottawa Ankle Rules which include:

-They are not always accurate in identifying fractures, particularly in children. False negatives can occur in up to 15% of cases.
-They require the examiner to have a good understanding of anatomy and physiology, as well as a high level of palpation skills.
-They only apply to fractures of the lower leg and not other injuries such as ligamentous sprains.

How can the Ottawa Ankle Rules be used in conjunction with other tests?

Ottawa Ankle Rules are commonly used in conjunction with other tests, such as the Proposed Clinical Tests for the Sensitivity and Specificity of the Ottawa Ankle Rules, to provide a more complete picture of an ankle injury. The Ottawa Ankle Rules have been shown to be sensitive in identifying fractures, but they are not specific for fracture diagnosis. In other words, the Ottawa Ankle Rules will often identify patients with fractures who would not have been diagnosed by other means. However, the Ottawa Ankle Rules will also often identify patients without fractures who would have been diagnosed by other means. Therefore, it is important to use the Ottawa Ankle Rules in conjunction with other clinical tests to make the best possible decision about whether or not to refer a patient for radiography.

How often are the Ottawa Ankle Rules updated?

The Ottawa Ankle Rules were initially published in 1992, and then updated in 2013. They are due for another update in 2018.

What is the evidence supporting the use of the Ottawa Ankle Rules?

The Ottawa Ankle Rules were first published in 1993, and since then, several studies have been conducted to assess their accuracy. A systematic review of the available evidence concluded that the Ottawa Ankle Rules are reliable for excluding fractures in adults1. Another study found that the Ottawa Ankle Rules had a sensitivity of 100% and a specificity of 96.7% for detecting ankle fractures2.

Overall, the evidence supports the use of the Ottawa Ankle Rules as an effective tool for excluding fractures in adults with ankle injuries.

Are there any alternative ankle rules?

Though the Ottawa ankle rules are the most commonly used clinical decision tool for foot and ankle radiographs, there are a few alternative ankle rules that have been developed. These include the NICE Guidance, Canadian C-Spine Rule, Toronto Extremity Rule, and the New Orleans Criteria.

The NICE Guidance is a set of integrated care pathways developed by the National Institute for Health and Clinical Excellence in the United Kingdom. The Canadian C-Spine Rule was developed in Canada and is similar to the NICE Guidance. The Toronto Extremity Rule was developed specifically for use in trauma patients, and the New Orleans Criteria was developed for use in pediatric patients.

All of these alternative ankle rules have been shown to be effective in reducing unnecessary radiographs, with high levels of interrater reliability. However, more research is needed to determine which clinical decision tool is most effective in different clinical settings.
