The wrist is a complex joint that connects the hand to the forearm. The wrist is comprised of the ends of the two forearm bones (the ulna and radius) and eight small bones called carpals.
The radius is positioned on the thumb side of the wrist, and the ulna on the pinky side.
The carpal bones are arranged in two rows. The first row is found where the wrist creases when we bend it and includes the scaphoid, lunate, triquetrum and pisiform. The second row of carpal bones, closer to the fingers, is made up of the trapezium, trapezoid, capitate and hamate.
Each bone within the wrist is joined to the one next to it by one or more ligaments. This complex configuration of ligaments in the wrist enables it to be extremely mobile while maintaining its stability. Most of the muscles that act on the wrist joint are located in the forearm.
A healthy wrist is extremely mobile to give our hands full range of motion. It is a super flexible joint, able to move and bend forward, backward and side to side. At the same time, the wrist must provide strength for gripping.
Wrist pain or injury can greatly impede a golfer's game. It can also make many activities of every day life difficult, if not impossible. That's why it's important to see a doctor for any pain that does not get better with rest or that lasts for more than a week.
Normal Range of Motion
One should be able to move the wrist comfortably forward, backward and side to side.
