Most frequently fractured carpal bone?

• A. Capitate
• B. Lunate
• C. Trapezium
• D. Scaphoid

Answer: (D)

When a person falls on an outstretched hand, the force is transmitted through the wrist to the scaphoid, which sits on the radial (thumb) side and bridges the proximal and distal carpal rows. This makes the scaphoid the most vulnerable carpal bone to fracture. Its typical fracture site is the waist, and such fractures are the most common among carpal injuries. The blood supply to the scaphoid enters mainly from the distal part and travels proximally, so a fracture—especially through the waist or near the proximal pole—can disrupt flow to the proximal fragment, risking avascular necrosis and nonunion. Clinically, tenderness in the anatomical snuffbox after a fall supports this injury pattern.
