Joints of the hand, X-ray. The bones in each carpal row interlock with each other and each row can therefore be considered a single joint. In the proximal row a limited degree of mobility is possible, but the bones of the distal row are connected to each other and to the metacarpal bones by strong ligaments that make this row and the metacarpus a functional entity.
The palmar intercarpal ligaments are fibrous bands that extend transversely across the palmar surfaces of the carpal bones, connecting adjacent carpals. These are the ligaments that define the structure of the ligamentous palmar arch .
Optimal wrist function requires stability of the carpal components in all joint positions under static and dynamic conditions. Stability is achieved by a sophisticated geometry of articular surfaces and intricate system of ligaments, retinacula , and tendons , which also determine the relative motion of the carpal bones.
The radial collateral ligament (external lateral ligament, radial carpal collateral ligament) extends from the tip of the styloid process of the radius and attaches to the radial side of the scaphoid (formerly navicular bone of the hand), immediately adjacent to its proximal articular surface and some fibres extend to the lateral side of the trapezium (greater multangular bone).

The joints in the hand are joints found at the distal end of the upper limb.. The joints are: In the wrist there is the radiocarpal joint between the radius and carpus.Between the carpal bones are the intercarpal articulations and the midcarpal joint.
The carpometacarpal (CMC) joints are five joints in the wrist that articulate the distal row of carpal bones and the proximal bases of the five metacarpal bones.. The CMC joint of the thumb or the first CMC joint, also known as the trapeziometacarpal (TMC) joint, differs significantly from the other four CMC joints and is therefore described separately.
The interosseous metacarpal ligaments (ligamenta metacarpalia interossea) connect their contiguous surfaces, just distal to their collateral articular facets. The synovial membrane for these joints is continuous with that of the carpometacarpal joints .
