The elbow is viewed as the most straightforward joint to exam with the cases usually being specific so if you get an elbow short case, you should breathe a sigh of relief. We don't share this view as many candidates will perform very poorly with an elbow case that was relatively routine and clear cut.
Look on the medial aspect of elbow whilst the patient actively moves the elbow through the flexion/extension range. On occasions we can see a ‘subluxing ulnar nerve over the medial epicondyle’ and if supported by clinical symptomatology further assessment of ulnar nerve dysfunction would be valuable - snapping elbow. The triceps tendon could also give rise to the clicky elbow but this is more evident when actively extending the elbow against resistance, in contrast to a subluxing ulnar nerve which happens when passively flexing and extending the elbow.
