The wrist acts like a bridge between your forearm and hand. It is made up of consists of the bottom end of the forearm (radius and ulna), 2 rows of bone called the carpal bones, and the base of the thumb and fingers in your hand. This allows the wrist to bend and straighten; rotate; and tilt.
The hand itself is made up of the long bones in your thumb and fingers. Together the wrist and hand have a total of 24 bones, and superficial and deep muscles that allow you to hold and manipulate things with fine control.
Common injuries to the wrist and hand include:
- Ligament injuries
- Peripheral nerve entrapments
