Ligaments of the wrist and hand
After going through this study unit you will be able to:
1. Identify the main joints of the wrist and hand.
2. Name and locate the ligaments that support those joints.
The ligaments are the connective tissue structures that connect two articulating bones. They participate in the stabilization of joints, but can also limit certain movements based on their position within the joint.
The wrist and hand feature several joints. Proximal to distal, the first one is the radiocarpal (wrist) joint which connects the forearm and the hand. The rest of the joints are in the hand, connecting groups of bones to each other (e.g. carpal and metacarpal), as well as individual bones amongst themselves (e.g. scaphoid and lunate). Namely, these joints are: intercarpal, carpometacarpal, intermetacarpal, metacarpophalangeal and interphalangeal joints.
The proper function of the ligaments is crucial for the normal mobility and function of the wrist and hand. This study unit will help you learn the anatomy and function of the ligaments of the wrist and hand.
