Finkelstein's Test is used to assess which pathology?

Finkelstein's Test is specifically designed to assess De Quervain's Tenosynovitis. This condition involves inflammation of the tendons on the thumb side of the wrist, particularly affecting the abductor pollicis longus and extensor pollicis brevis tendons. During Finkelstein's Test, the patient is asked to make a fist with the thumb tucked inside the fingers and then the wrist is ulnarly deviated. If this maneuver elicits pain over the radial side of the wrist, it typically indicates an issue with these tendons, thereby confirming the presence of De Quervain's Tenosynovitis.
