Dr. Gregg Vagner explains basic wrist anatomy and enumerates the complex system of joints, bones, and nerves it involves. The wrist is a vital part of our daily functions, which can be easily compromised by problems such as arthritis or tendonitis. Dr. Vagner offers a range of treatments for wrist-related problems.
The anatomy of the wrist begins with the two forearm bones, the radius and the ulna. There's a joint between these two bones that allows the radius to rotate around the ulna. Next is the wrist joint itself, and that's actually made up of two joints, the radiocarpal joint and the ulnocarpal joint. After this first row of carpal bones, you have another joint called the midcarpal joint, and that allows us what we commonly refer to as a dart thrower's motion.
On top of the bones and joints of the wrist, we have many flexor tendons that cross the wrist on one side and extensor tendons that cross the wrist on the other. In addition, we have three nerves that cross the wrist. We have the median nerve that crosses the wrist and goes into the carpal tunnel. On this side, we have the ulnar nerve, and on the back, we have a branch of the radial nerve.
And that's basic wrist anatomy.
