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.

**Note that calculating probabilities from more than one finding is inherently inaccurate because findings are not independent. (For example, using two positive findings that share a common pathogenesis is likely to overestimate the true probability.)
