In the study of the anterior ulna collateral ligament you mention dynamic assessment. Do you merely straighten/bend the elbow to assess? If not, what is the method?
I have the patient sitting opposite me, I ask the patient to hold their humerus stabilising it while I apply external rotation to the forearm opening up the medial elbow joint line (valves stress test)
I can also do it with the patient supine and arm above head by pushing down on the forearm.
Basically you are trying to open up the medial elbow joint line,
