What test is used to indicate if de Quervain's tenosynovitis is present?

Finkelstein's Test is specifically designed to assess for de Quervain's tenosynovitis, a condition that affects the tendons around the thumb, causing pain and discomfort in the wrist and thumb area. During Finkelstein's Test, the patient is asked to make a fist with the thumb tucked inside the fingers and then ulnarly deviate the wrist. A positive result, indicated by pain along the radial side of the wrist, suggests inflammation of the abductor pollicis longus and extensor pollicis brevis tendons, which are commonly involved in this condition.

The other tests listed, such as Phalen's Test, are used to evaluate different conditions, primarily carpal tunnel syndrome. Hawkins-Kennedy Test assesses for shoulder impingement instead. The Grid Test does not apply to the assessment of de Quervain's tenosynovitis. By knowing the specific purpose of Finkelstein's Test, it becomes clear why it is the correct choice to identify de Quervain's tenosynovitis.
