Elbow joint

The elbow joint, also known as the articulation of the elbow, is one of the most complex and functionally important joints in the human body. It is formed by the connection of three bones: the humerus, radius and ulna.

The articulation of the elbow consists of three different joints: the radioulnar, ulnohumeral, and proximal radioulnar joints. Each of these joints performs a unique function, allowing the human upper limb to perform a wide range of movements.

The radioulnar joint is the largest of the three and provides movement of the arm around its longitudinal axis. It is formed by the head of the radius and the inner part of the ulna. The radioulnar joint allows a person to rotate the hand inward and outward, as well as supination and pronation of the hand.

The ulnohumeral joint is formed by the union of the upper part of the ulna and the lower part of the humerus. This joint is responsible for moving the arm up and down, as well as rotating the arm around its longitudinal axis.

The proximal radioultra joint connects the upper part of the radius and the lower part of the ulna. It provides slight movement of the hand and allows it to tilt towards the thumb and little finger.

The elbow joint is one of the most vulnerable places in the human body and can be subject to injury and damage during various sports, as well as during everyday life. If you experience any pain or unusual sensations in the elbow joint, you should consult a doctor for diagnosis and treatment.
