Anterior Drawer Test

Examination type Joint stability
Patient & Body Segment Positioning Patient lies supine with shoulder completely relaxed and supported by the examiner in 80-1200 of abduction, forward flexion up to 200, and up to 300 of external rotation while the elbow is extended.
Examiner Position Examiner places hand of the involved shoulder in the examiner’s axilla to hold the patient’s arm and maintain shoulder relaxation. One hand is placed on top of the shoulder and pushes downward to stabilize the scapula while the other hand is placed around the upper humerus.
Performing the Test The examiner pushes down on the hand stabilizing the scapula while using the hand around the upper humerus to pull the humeral head forward.  Perform the test again on the uninvolved shoulder and compare bilaterally.
Tissues Being Tested Labrum of the glenohumeral joint, rotator cuff muscles
Positive Test Abnormal anterior translation as compared bilaterally; clicking during the test
Interpretation Extra anterior translation indicates anterior joint instability.  Clicking can indicate a labral tear or the humeral head slipping over the rim of the glenoid.
Common errors in performing exam Incorrect hand placement of the examiner which can result in incorrect patient body segment positioning.
Factors possibly resulting in misinterpretation Pre-existing joint hyper mobility; Always check bilaterally
Related tests Pre-existing joint hyper mobility; Always check bilaterally
