Finkelstein’s Test
Finkelstein’s test is used to determine DeQuervain’s Tenosynovitis. To perform this test, grasp the patient’s thumb and hand and deviate them ulnarly. Alternatively, you can ask the patient to make a fist with their thumb inside their fingers and ulnarly deviate the wrist on their own. A positive test will produce a sharp pain along the distal radius where the tendons of Abductor Pollicis Longus and Extensor Pollicis Brevis are located.
