radiocarpal

-- The carpal bones as they articulate with one another and with the radius and metacarpal bones, as classed by anatomists, form three distinct articular parts of the joint as a whole and are known as radiocarpal, intercarpal and carpometacarpal.

Lameness of the Horse Veterinary Practitioners' Series, No. 1 John Victor Lacroix

—The dorsal radiocarpal 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, lunate, and triangular, being continuous with those of the dorsal intercarpal ligaments.

M. Johnston (Journal of Anatomy and Physiology, vol. xli) maintains that n ulnar and radial flexion only slight lateral movement occurs at the radiocarpal joint, and that in complete flexion and extension of the hand there is a small degree of ulnar flexion at the radiocarpal joint.

—The volar ligaments, also two, connect the navicular and lunate, and the lunate and triangular; they are less strong than the dorsal, and placed very deeply behind the Flexor tendons and the volar radiocarpal ligament.

III. Syndesmology. 6g. Intercarpal Articulations 1918

The dorsal surface is convex, affords attachment to the dorsal radiocarpal ligament, and is marked by three grooves.

II. Osteology. 6a. 5. The Radius 1918

The volar surface, rough and irregular, affords attachment to the volar radiocarpal ligament.

II. Osteology. 6a. 5. The Radius 1918

A prominent ridge limits the insertion of the Pronator quadratus below, and between this and the inferior border is a triangular rough surface for the attachment of the volar radiocarpal ligament.

II. Osteology. 6a. 5. The Radius 1918

This suggests that activities that place chronic stress on the radiocarpal joint can independently affect radioulnar deviation.
