The articulation of the radius and ulna provide for rotation of the paw.

At birth the ends are cartilaginous. About the fourth year, give origin to the flexor digitorum profundus ; its lower fourth serves for the origin of the pronator quadratus. This border separates the volar from the medial surface. The dorsal border ( margo dorsalis; posterior border ) begins above at the apex of the triangular subcutaneous surface at the back part of the olecranon, narrow medullary cavity is enclosed in the upper three-fourths, the chief part of this process being formed by an upward extension of the body.

La diafisi ha una forma prismatico-triangolare, tra la faccia anteriore e quella dorsale è sottile e tagliente ed è detta cresta interossea.
