Which MSD is also known as trigger finger?

• A. Trigger Finger
• B. Stenosing tenosynovitis (trigger Finger)
• C. Tendonitis
• D. Carpal Tunnel Syndrome

Answer: (B)

Trigger finger is the common name for the condition known medically as stenosing tenosynovitis. It happens when the flexor tendon sheath at the base of the finger (typically around the A1 pulley) becomes inflamed and narrows, so the tendon has trouble gliding. The finger may catch, snap, or lock in a bent or straight position as you move it. This is a musculoskeletal issue of tendon movement, not just general tendon inflammation or nerve compression. Tendonitis refers to inflammation of a tendon elsewhere, and carpal tunnel involves median nerve compression at the wrist, so they don’t describe the same mechanism. The precise term that corresponds to trigger finger is stenosing tenosynovitis (trigger finger).
