So, just to clear something up. 4 consecutive steps without pain. So what happens if a patient completes 4 consecutive steps fully weight bearing with pain yet when the patient is partial weight bearing they have no pain? Cheers
Brilliant video guys but can you just clarify the following please. At the end of the video you state if 1 from 3 is positive and if 0 from 3 positive this indicate ...... however arent we looking at more than 3 items here? Am i missing something?
The study said that there is a sensitivity of 96-99% and a specificity of 26-47%, and then you make the conclusion, that "if the ottowa ancle rules are negativ, chances of a fracture is low", and that is not korrekt. For that to be true, we need a high negativ prediktive value (NPV).
Hi Johanne, the problem with the NPV is that it depends on the prevalence and to exclude a fracture you'd want to end up with a very low value. Best thing to do is to take the negative likelihood ratio, which is 0,15 (worst case) and 0,02 (best case) if we calculate it from the sensitivity and specificity. So if we assume a prevalence for a fracture of 15% and calculate with the likelihood, we'll end up with a chance of a fracture somewhere between 0,35% - 2,5%.
For the Ottawa ankle rules, you forgot to mention to palpate the navicular bone too for pain which is also indicatif of an ankle fx, otherwise awesome video!

Thanks for this informative video, really liked the explanation in the ebook!
Glad it was helpful!
What is the test sign with the 4 step walking test to determine if it is positive or negative? I don't believe the video gave that info?
Very effective thank you
Thank you so much for simplifying this 🙏🏿🙏🏿🙏🏿
Can I ask, should the reaction of the patient be pain, or a protrusion of the bone(s)? What is the signifying and defining thing to say it is broken?
Y'all are awesome!
Great video.
Thanks Benedikte 👍🏼
How does this pain pass and how long does it last?
Would it be light palpation? And what type of pain pt would experience?
Hi what constitutes a negative for the criterions? No pain?
Yes, no pain and the ability to walk 4 consecutive steps.
+meego2 exactly, no pain/tenderness upon palpation
So, just to clear something up. 4 consecutive steps without pain. So what happens if a patient completes 4 consecutive steps fully weight bearing with pain yet when the patient is partial weight bearing they have no pain?
