 Posterior Drawer Test of the shoulder

What is Posterior Drawer Test of the shoulder?

How it’s Performed?

What does a positive Posterior Drawer Test of the shoulder mean?

Notes

The examination may also be performed with the patient seated. With the patient in a relaxed posture bending slightly forward with the arm hanging alongside the trunk, the examiner places his or her thumb on the patient’s scapular spine or posterior glenoid and grasps the humeral head anteriorly. Applying rotation and pressure with the fingers will provoke posterior subluxation of the head where there is sufficient laxity in the capsular ligaments.

In posterior instability, the humeral head can be posteriorly displaced by one-half its diameter.
