Sample itemWhich structure is palpated in the anatomical snuffbox after a fall onto an outstretched hand to assess possible scaphoid injury?
Original practice item, not a recalled exam question. Nothing here is recorded.
The answer and the reasoning
C. Scaphoid bone
The scaphoid forms part of the floor of the anatomical snuffbox, and tenderness there after a fall raises concern for fracture because its proximal blood supply can be vulnerable to disruption.

Capitate is a central distal-row carpal bone.
B. Lunate bone
Lunate lies more centrally in the proximal carpal row.
C. Scaphoid bone (correct)
Correct: snuffbox tenderness is associated with possible scaphoid fracture.
D. Pisiform bone
Pisiform is a palmar ulnar carpal bone.
