What is Froment’s sign test?
Froment’s Sign. Froment’s sign is a test for Ulnar Nerve palsy, specifically testing the action of Adductor Pollicis. To perform this test, ask the patient to hold a piece of paper in between her thumb and index finger and attempt to pull the paper from the patient’s grip. A normal test is when the patient is able to maintain ahold of the paper.
What is the purpose of Froment's sign?
Purpose. Froment's sign is a physical examination of the hand to test for palsy of the ulnar nerve which results in reduced functionality and muscle weakness of the pinch grip. It tests the strength of the adductor pollicus of the thumb, which is innervated by the ulnar nerve and is weakened in ulnar nerve palsy.

Froment’s sign: As paper is pulled away by the examiner, thumb on left shows IP joint flexion as compared to thumb on right.

What does a positive Froment sign mean?
Froment sign is Positive if the paper is pulled away by the examiner because of weakness or loss of function in adductor pollicis muscle, where the patient flexes the thumb interphalangeal joint in an attempt to hold on to paper (due to contraction of the flexor pollicis brevis, which is supplied by the median nerve).

How do you fix Wartenberg syndrome?
Diagnostic procedures. In de Quervain disease, injection of cortisone and lidocaine into the tendon sheath of the extensor pollicis brevis and the abductor pollicis longus relieves the symptoms immediately and sometimes permanently.
