The Yergason test is a special test used for orthopedic examination of the shoulder and upper arm region, particularly the biceps tendon.

Destination

It identifies the presence of pathology involving the biceps tendon or glenoid labrum. Specific positive findings for this test include: pain in the bicipital groove showing biceps tendinitis, subluxation of the brachii biceps bicepal head, and the presence of a SLAP tear.

Procedures

Palpate the biceps tendon as it passes through the bicipital groove to identify lesions, abnormal bulges, or abnormal movements (ie the biceps tendon) in the area involved.

Mechanism

To perform the test, testers should stand on the affected side of the patient. The patient should be in a sitting position with the elbow flexed up to 90Ã, Â °, the palpable arm (palm facing to the ground), and the arm steady against the thorax. The examiner places the stabilizer hand on the proximal portion of the humerus near the bicipital groove, and hand the resistance to the distal forearm of the distal and wrist.

The patient is instructed to actively supine the forearm, externally rotate the humerus, and flex the elbow against the examiner's resistance. The pain caused by the patient results in one of the positive findings.

• Modifications involve the examiner holding the flex elbow as the humerus moves into an external rotation.

Results

Biceps tendinitis or subluxation of the biceps tendon can usually be resolved by palpation of the biceps tendon's long head in the bicipital groove. The patient will show a pain, broken or both response in the bicipital groove. Pain without associated popping may indicate bicipital tendinopathy. Snapping indicates a tear or weakness of the transversal humeral ligament, which will prevent the ligaments from securing the tendon within the groove. Pain in the superior glenohumeral joint is an indication of SLAP rupture.

Adverse effects

This is a difficult test for an accurate diagnosis. False-positive findings can be the result of a rotator cuff tear, while pain in the superior glenohumeral region is a weak predictor of SLAP tears.
