The elbow joint is a synovial joint and a classic hinge joint.

It has three bones, the humerus, radius (the thumb side) and the ulna (the little finger side) producing two joints:

1. Humeroradial joint -lateral articulation of capitulum of humerus with head of the radius.

2. Humeroulnar joint -medial articulation of trochlea of humerus with trochlear notch of the ulna.

Both components of the elbow joint are surrounded by single joint capsule and stabilized by collateral ligaments

Medial and lateral epicondyles are externally palpable bony landmarks.

The olecranon bursa ( a fluid filled sac ) is independent of elbow joint space. Inflammation is called olecranon bursitis.

Trauma to the ulnar nerve at the elbow results in unpleasant sensations in those fingers and part of hand supplied by the nerve ("funny bone"); severe injury may cause "wrist drop"
