Detection and Diagnosis
The scaphoid bone is one of the carpal bones on the thumb side of the wrist. This bone is important for both motion and stability in the wrist joint, and it can most easily be identified when your thumb is held in a “hitch-hiking” position.
A scaphoid fracture usually occurs when you fall onto an outstretched hand, with your weight landing on your palm. The end of the larger forearm bone (e.g., the radius) may also break in this type of fall, depending on the position of the hand on landing. The injury can also happen during sports activities or motor vehicle collisions.
Fractures of the scaphoid occur in people of all ages, including children. There are no specific risk factors or diseases that make you more likely to experience a scaphoid fracture.
