Which carpal bone is the most commonly fractured?

• A. Triquetrum
• B. Scaphoid
• C. Lunate
• D. Pisiform

Answer: (B)

The scaphoid bone is recognized as the most commonly fractured carpal bone due to its anatomical position and unique blood supply. Located at the base of the thumb and articulating with the radius, the scaphoid plays a crucial role in wrist stability and movement. Its fractures often occur from falls onto an outstretched hand, a common mechanism of injury. One of the key factors contributing to the frequency of scaphoid fractures is its blood supply, which comes from the distal end of the bone. This supply can be compromised in fractures, especially those that occur in the waist region of the scaphoid, leading to complications like avascular necrosis. The other carpal bones, while they can also sustain fractures, are less commonly involved. The triquetrum, lunate, and pisiform bones do not have the same incidence of fractures related to typical traumatic events, and their injuries tend to present differently. Understanding this context is essential for assessment and treatment in the field of orthopedic technology.
