What is the Hook test used to diagnose?

• A. Lateral epicondylitis
• B. Medial epicondylitis
• C. Bicipital distal tendon rupture
• D. Distal biceps tendonitis

Answer: (C)

The Hook test is a quick bedside maneuver to assess the distal biceps tendon at the radial tuberosity. With the elbow bent to about 90 degrees and the forearm supinated, you try to hook the distal biceps tendon between your thumb and index finger. If the tendon is intact, you can hook it and feel it in place; if the distal tendon has ruptured, the tendon retracts and you cannot hook it, giving a positive test. This makes it a focused way to identify distal biceps tendon rupture, rather than conditions like lateral or medial epicondylitis or distal biceps tendonitis, which do not involve a complete rupture detectable by this test.
