Technique
[edit | edit source]

The test is considered positive when a sulcus sign is seen when the examiner applies a downward force applied at the elbow while the arm in neutral rotation and resting at the patient's side.  A sulcus is defined as a depression greater than a fingerbreadth between the lateral acromion and the head of the humerus.[2]
