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 |
