Ligament: Ulnar collateral ligament (elbow)
Left elbow-joint, showing anterior and ulnar collateral ligaments. (Ulnar collateral lig. visible at center left.)
Latin	ligamentum collaterale ulnare
Gray's	subject #84 322
From	medial epicondyle of the humerus
To	coronoid process of the ulna (anterior), olecranon (posterior)

The ulnar collateral ligament (internal lateral ligament) is a thick triangular band consisting of two portions, an anterior and posterior united by a thinner intermediate portion.

• The anterior portion, directed obliquely forward, is attached, above, by its apex, to the front part of the medial epicondyle of the humerus; and, below, by its broad base to the medial margin of the coronoid process.

• The posterior portion, also of triangular form, is attached, above, by its apex, to the lower and back part of the medial epicondyle; below, to the medial margin of the olecranon.

Between these two bands a few intermediate fibers descend from the medial epicondyle to blend with a transverse band which bridges across the notch between the olecranon and the coronoid process.

This ligament is in relation with the Triceps brachii and Flexor carpi ulnaris and the ulnar nerve, and gives origin to part of the Flexor digitorum sublimis.
