The Dorsal Ligaments

The dorsal ligaments, (dorsal radiocarpal or DRC and dorsal intercarpal or DIC) are the two ligaments of the wrist. They are placed transversely behind the bones of the first row; they connect the navicular and lunate, and the lunate and triangular. The DRC ligament was consistently found to originate from the dorsal margin of the distal radius and extended ulnar obliquely and distally. Its fibers attached to the lunate and lunotriquetral interosseous ligament.

These two ligaments enable the wrist to move in all directions, providing flexibility and range of motion. The dorsal ligaments of the wrist can be divided into superficial and deep.
