Stress test

After a much needed week long vacation I am back to the real world. I haven't seen anything too interesting today.
Here is a stress test exam done on a young child. I believe the test was positive due to the differences in the gap between the lateral malleolus and the talus.
A stress view is when the doctor comes in and puts stress both joints (like ankles or fingers) in one at a time. This is to see if there is joint instability or ligament tears. They are also used when testing for non union fractures.
For ankle stress films the patient is supine with both legs outstretched. There is then pressure applied on the lateral aspect of the foot, adducting the heel and forcing the foot into a varus position.
