Anatomy (Bone)

The elbow is a hinge joint and consists of the humero-ulnar, humero-radial and proximal radio-ulnar articulations. The radial head articulates with the humeral capitellum whilst the trochlear notch of the ulna articulates with the humeral trochlea. Posteriorly the ulna forms the olecranon, which contacts the olecranon fossa of the humerus at full elbow extension.

Anatomy of the joint – The elbow joint allows from 00 to approximately 140-1500 of flexion7.
