Inferior Sulcus Test
Original Editor - Tyler Shultz
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.
