Posterior depression on the distal humerus.
The "distal humerus" is the lower end of the humerus (upper arm bone). (Right) The major nerves and ligaments of the elbow are highlighted. The elbow consists of portions of all three bones: The distal humerus is the lower end of the humerus.

The Capitulum is a rounded eminence forming the lateral part of the distal humerus. The head of the radius articulates with the capitulum. Capitulum on the lateral side and trochlea on the medial side of the Humerus. The trochlea is spool-shaped medial portion of the distal humerus and articulates with the ulna. Trochlea of the Humerus EpicondylesA small cavity called the olecranon fossa on the posterior side of the bone locks the olecranon or the tip of the ulna into the bone. This locking prevents us from extending the elbow beyond 180 degrees. Despite this, the distal portion of the humerus also contains two other depressions, known as the coronoid and radial fossae.
