A Correct answer
Explanation

Canaval sign (likely a variant or regional term for Finkelstein's maneuver/test) is used to diagnose de Quervain's tenosynovitis. The test involves flexing the thumb into the palm, grasping it with the fingers, and then ulnarly deviating the wrist. Pain over the radial styloid process indicates a positive test, suggesting inflammation of the abductor pollicis longus and extensor pollicis brevis tendons. Dupuytren's contracture involves palmar fascia, carpal tunnel involves median nerve compression, and trigger finger involves flexor tendon locking.
