What finding on physical examination suggests a biceps tendon rupture?

• A. A gap where the rupture occurred.
• B. Positive Lachman test.
• C. Deformity of the wrist.
• D. Absent radial pulse.

Answer: (A)

A rupture of the biceps tendon causes the muscle belly to retract, producing a palpable gap at the site of the tear. This gap, often accompanied by a Popeye-like deformity, is the most specific sign of a biceps tendon rupture. The Lachman test is used for ACL injury in the knee, wrist deformity isn’t typical for a tendon rupture, and an absent radial pulse points to arterial problems rather than a tendon tear.
