Hook test
Test carried out to confirm the presence of a distal biceps tendon rupture. The patient abducts the shoulder to 90 degrees with the elbow flexed to 90 degrees and the arm supinated so that the thumb faces up. The patient then actively supinates the forearm against resistance of the examiner, with the index finger of the other hand the examiner attempts to hook underneath the biceps tendon and if no cordlike structure can be hooked, the test is positive for a rupture of the distal biceps.
