Finkelstein's test

The Finkelstein Test is a clinical examination maneuver used to diagnose deQuervain’s tenosynovitis, a condition characterized by pain and swelling in the wrist on the thumb side. The test is named after the American surgeon Harry Finkelstein, who first described it in the early 20th century.

Defintion

The Finkelstein Test is a physical examination technique used primarily to identify the presence of deQuervain’s tenosynovitis in patients who present with wrist or thumb pain. DeQuervain’s tenosynovitis results from the inflammation of the tendons located at the base of the thumb, which can cause pain, swelling, and restricted movement.

Procedure

To perform the Finkelstein Test:

1. The patient is asked to make a fist with their thumb tucked inside the fingers. 2. The examiner then gently ulnar deviates the wrist, meaning the hand is moved towards the little finger. 3. A positive test is indicated by sharp pain along the distal radius, especially over the tendons of the first extensor compartment.

Interpretation

Pain that radiates up the radius during this test suggests the presence of deQuervain’s tenosynovitis. While the Finkelstein Test is useful for identifying this specific condition, it's essential to consider the clinical context and other potential causes of wrist pain.

Limitations

While the Finkelstein Test is a valuable tool in diagnosing deQuervain’s tenosynovitis, it is not infallible. There are instances where patients with the condition might not show a positive test result, and likewise, a positive result may sometimes appear in patients without the condition. Hence, it is vital to combine the test results with clinical history and other diagnostic measures.
