Which test is used to assess trigger finger?

• A. Finkelstein's Test
• B. catch test on digital flexion
• C. Neer's test
• D. Drawer sign

Answer: (B)

Trigger finger results from narrowing of the flexor tendon pulley system, usually at the A1 pulley, causing the tendon to catch or lock as it glides. The catch test on digital flexion is designed to provoke that exact mechanical issue: when the patient actively or passively flexes the affected finger, you feel or hear a distinct catch or snap as the tendon slides through the pulley. That palpable or audible catching is characteristic of trigger finger, making this test the most appropriate to assess it.

Other tests target different conditions. Finkelstein’s test checks for De Quervain’s tenosynovitis at the thumb side; Neer’s test looks for shoulder impingement; drawer signs assess knee ligament stability. Those do not specifically diagnose trigger finger, so they’re not as relevant here.
