Yergason's test
Yergason's Test
Yergason's Test (pronounced: Yer-ga-son's Test) is a physical examination procedure used to diagnose biceps tendon pathology, particularly biceps tendonitis or biceps tendon instability. The test is named after the American orthopedic surgeon, Dr. Samuel Yergason, who first described it in 1931.
Etymology
The term "Yergason's Test" is derived from the name of its inventor, Dr. Samuel Yergason. The word "test" is derived from the Old French test, meaning "small vessel".
Procedure
The Yergason's Test is performed with the patient seated and the elbow flexed at 90 degrees. The examiner resists the patient's active attempt to supinate the forearm and flex the elbow. Pain or a "pop" in the bicipital groove area indicates a positive test.
Interpretation
A positive Yergason's Test suggests pathology of the long head of the biceps tendon. This could be due to biceps tendonitis, biceps tendon instability, or a SLAP lesion (Superior Labrum from Anterior to Posterior lesion).
