Which test or symptom would be positive for a Scaphoid Fracture?

A scaphoid fracture, a common wrist injury particularly in young adults, is often assessed through specific symptoms and tests. Snuffbox tenderness is a key physical finding associated with this type of fracture. This tenderness is located in the anatomical snuffbox, a triangular depression on the radial side of the wrist, formed by the extensor pollicis longus and brevis tendons, with the scaphoid bone lying deep within it. When a scaphoid fracture is suspected, palpating this area can elicit tenderness, which indicates potential injury to the scaphoid bone itself.

This tenderness is particularly significant because the scaphoid bone has a limited blood supply; fractures there may lead to complications such as avascular necrosis if left unrecognized and untreated. Hence, the presence of tenderness in the snuffbox is a strong indicator of a potential scaphoid fracture and guides further imaging and management decisions.

In contrast, the other options listed do not specifically correlate with a scaphoid fracture. For example, the Finkelstein test is utilized to diagnose de Quervain's tenosynovitis and is not relevant to scaphoid fractures. The Straight Leg Raise assesses for lower back issues and sciatica,
