- Radial scaphoid column: scaphoid, trapezium, and trapezoid.
- Lunate column: lunate and capitate.
- Ulnar triquetral column: triquetrum and hamate.
Which carpal bone is most commonly fractured?
Scaphoid fractures are by far the most common of the carpal fractures, and account for 10 percent of all hand fractures and about 55 percent of all carpal fractures [1,4-8]. The triquetrum is the second most common carpal fracture, comprising about 21 percent.

Which is the largest carpal bone?
The capitate bone is the largest of the carpal bones in the human hand. It presents, above, a rounded portion or head, which is received into the concavity formed by the scaphoid and lunate bones; a constricted portion or neck; and below this, the body.
