Wrist Anatomy

hand-ulna-radiusThe wrist is the most commonly broken bone in the human body. It’s a natural reaction, when we fall, to put our hands out to catch ourselves and … ouch … that’s when most wrist breaks or fractures occur.

There are a number of small bones referred to as “carpal” bones and two long bones known as the Radius and Ulna. The Radius is the larger of the two in the wrist area.

Usually, when a doctor describes a wrist fracture, he or she is referring to a break of the Radius bone. There are other types of wrist breaks, but generally, a “broken wrist” means that the end of the forearm bone has been broken.
