Purpose

Sulcus Sign

The Sulcus Test is used to assess the glenohumeral joint for inferior instability, due to laxity of the superior glenohumeral ligament and coracohumeral ligament.[1]

Technique

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]
