Elbow - Definition


Definition

The elbow is an articulation of the upper limb which joins the arm to the the forearm, and particularly three bones: humerus, radius and ulna.
Also called alecranon articulation, the elbow is composed in three articulations, which allow different moves of the arm: flexion/extension, rotation, pronation and supination.

Elbow pathologies are common (dislocations, tendinits...), almost for old people with arthritis problems affecting cartilage.
