Elbow, Wrist & Hand

What It Is

The scaphoid is one of the bones in the wrist. To be more precise, it is one of the carpal bones. This particular bone is on the thumb side of the wrist, between the forearm and the hand (AAOS, n.d.).

The scaphoid is the most commonly broken carpal bone, and the injury typically happens in young men aged 15 to 25 (Clementson, Björkman and Thomsen, 2020), although it can happen at any age, including in children (AAOS, n.d.). It is usually caused by falling onto an outstretched hand, but it can also happen from a direct blow to the wrist, punching, sports injuries or road accidents (AAOS, n.d.; UHS, 2025). Sports such as snowboarding and skateboarding carry a risk.

Occasionally a person is unaware they have a scaphoid fracture. The wrist pain is thought to be a sprain, and the swelling goes down (AAOS, n.d.). However, the pain sometimes does not completely go away, so people seek treatment many months after a fall wondering why their wrist has not healed. In these cases, a fracture through the middle of the bone can disrupt its blood supply and stop the two pieces joining (non-union) (AAOS, n.d.). A scaphoid fracture does not always show up on the first X-ray, so doctors may treat a suspected fracture as a fracture until it is ruled out (UHS, 2025).

Scaphoid Fracture of the Wrist Anatomy

In order to gain a better understanding of this type of wrist fracture, it will be of some assistance to know a bit about the anatomy of the wrist.

The wrist is formed by the two forearm bones, the radius and the ulna, and eight small carpal bones (AAOS, n.d.). The eight carpal bones are the pisiform, triquetrum, capitate, hamate, trapezium, trapezoid, lunate and of course, the scaphoid. These bones are all held together by ligaments.

Between your thumb and wrist you have the scaphoid, which sits at the base of a natural dip between two thumb tendons known as the "anatomical snuff box" (AAOS, n.d.).
