Yergason's test an orthopedic physical examination test used in assessing the biceps tendon and glenoid labrum.
Purpose of the test[edit]
The test tries to elicit: pain in the bicipital groove indicating biceps tendinitis, subluxation of the long head of the biceps brachii muscle, and presence of a SLAP tear
History[edit]
- Yergason described the case of a woman with bicipital pain that was confirmed with isolated forearm supination.
- Since publication of this respective case report in 1931, orthopedic assessment textbooks have provided a wide range of descriptions for Yergason's Test and what a positive sign implicates.
Limitations[edit]
- Vast differences in hand placement, along with the vernacular for shoulder, forearm, and elbow motions, have been associated with Yergason's Test.
- Many authors associate pain with the maneuver as a diagnosis for a rupture of the transverse humeral ligament (THL) and subsequent subluxation of the long head of the biceps tendon (LBT).
- Many now believe that the THL is not a distinct ligament; rather, support of the LBT within the bicipital groove occurs from a fibrous extension of the subscapularis tendon.
- The evaluation of the subscapularis when a subluxing LBT is suspected is critical.
