Froment sign
Pronunciation: froh-MAHN
A clinical test indicating ulnar nerve weakness, characterized by thumb IP joint flexion when attempting to grip paper.
Full Definition
The Froment sign is a positive clinical finding that indicates weakness of the adductor pollicis muscle due to ulnar nerve dysfunction. When a patient attempts to hold a piece of paper between their thumb and index finger, weakness in thumb adduction causes compensatory flexion at the interphalangeal joint of the thumb. This test is commonly performed in hand surgery evaluations to assess ulnar nerve integrity, particularly in cases of cubital tunnel syndrome or ulnar nerve injury at the wrist.
Usage
Usage note: Often misspelled as 'Fromont' - ensure correct French spelling with 'e'
