Anatomical terms of bone

The olecranon fossa is a deep triangular depression on the posterior side of the humerus, superior to the trochlea. It provides space for the olecranon of the ulna during extension of the forearm.

Structure

The olecranon fossa is located on the posterior side of the distal humerus.[1][2]

The joint capsule of the elbow attaches to the humerus just proximal to the olecranon fossa.[3][4]

Function

The olecranon fossa provides space for the olecranon of the ulna during extension of the forearm, from which it gets its name.[2][5]

Other animals

The olecranon fossa is present in various mammals, including dogs.[6]
