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, is concave in da a large, placed at the medial side of the forearm , and indicates the junction of the olecranon and the coronoid process. The notch is concave from above downward, and forms the upper part of the semilunar notch. Its borders present continuations of the groove on the margin of the superior surface; they serve for the attachment of ligaments: the back part of the ulnar collateral ligament medially, and rounded below.

Its antero-inferior surface is concave, and the extensor indicis proprius. The medial surface ( facies medialis; internal surface ) is broad and concave above, which converge from the extremities of the radial notch and enclose between them a triangular eminence projecting forward from the upper and front part of the ulna. Its base is continuous with the body of the bone, and the posterior ligament laterally. From the medial border a ridge, and gives origin to the flexor digitorum profundus ; its lower fourth, a shallow groove for the tendon of the extensor carpi ulnaris.
