Scaphoid (left) (Os scaphoideum)
Educational content only — not medical advice.
Anatomy
The largest proximal-row carpal, boat-shaped, bridging radius and first metacarpal and forming the floor of the anatomical snuffbox; it is the most frequently fractured carpal when falling on the outstretched hand. This is the left member of the pair.
Clinical notes
Snuffbox tenderness after a fall demands careful imaging even with normal X-rays: its retrograde intraosseous blood supply turns an unhealed fracture into avascular necrosis.
