Dorsal radiocarpal ligament

The dorsal radiocarpal ligament (posterior ligament) less thick and strong than the volar, is attached, above, to the posterior border of the lower end of the radius; its fibers are directed obliquely downward and medialward, and are fixed, below, to the dorsal surfaces of the navicular (now known as scaphoid), lunate, and triangular, being continuous with those of the dorsal intercarpal ligaments.

It is in relation, behind, with the Extensor tendons of the fingers; in front, it is blended with the articular disk.
