Shoulder - Instability: Sulcus Sign - Female

3D ModelNoAI

The sulcus sign tests for inferior glenohumeral instability. With the patient sitting or standing, the examiner grasps the patient’s arm and pulls inferiorly. The test is positive if a dimple or sulcus appears beneath the acromion as the humeral head is translated inferiorly.
