According to the American Society for the Surgery of the Hand (ASSH), the most common wrist fracture is what is known as a distal radius fracture. Distal radius fractures occur in the distal end of the radius bone. The radius bone is the larger of your two forearm bones. At the point where the radius bone meets your wrist, it is called the distal end of the radius bone. Distal radius fractures most often occur when an individual braces their fall with an outstretched or flexed hand. That said, the wrist has ten bones, which all have the potential for fracture, including the ulna and the carpal bones, which are comprised of the capitate, hamate, pisiform, scaphoid, trapezium, trapezoid, and triquetral bones.
