Structure edit

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 edit

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 edit

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