Proximal Biceps Tendon Tear: Likelihood Ratios

Introduction: aka tear of the Long Head of the Biceps (brachii). The tendon of the long head passes along the intratubercular groove of the humerus into the joint capsule at the head of the humerus, and attaches to the scapula at the supraglenoid tubercle.

Physical exam tends to be of limited specificity, as many times Rotator Cuff Tear elicits positive tests.

Good Positive Likelihood Ratio

Yergason's Test

0.7

for biceps tendon pathology OR Superior Labral Anterior Posterior Lesion

In this test, the patient's elbow is flexed to 90 degrees with the thumb up. The examiner grasps the wrist, resisting attempts by the patient to actively supinate the arm and flex the elbow. Pain with this maneuver indicates biceps tendonitis.

Poorly Diagnostic Findings

Speed Test

1.5

0.7

The patient's elbow is flexed 20 to 30 degrees with the forearm in supination and the arm in about 60 degrees of flexion. The examiner resists forward flexion of the arm while palpating the patient's biceps tendon over the anterior aspect of the shoulder.
