In conjunction with the shoulder joint and wrist, the elbow gives the arm much of its versatility, as well as structure and durability. Some of the areas of secondary ossification are as follows: A supracondylar fracture is a fracture to the humerus above the level of the humeral condyles. The first joint, called the humero-ulnar joint, is between the trochlea of the humerus and the trochlear notch of the ulna; and second one, called the humero-radial joint situated between the capitulum of the humerus and the superior aspect of the head of the radius. Extension of the forearm at the elbow joint is the increase of the angle at the elbow to bring the forearm back to the anatomical position from a flexed position. Elbow joint: humero-ulnar joint, humeroradial joint and proximal radioulnar joint. The bones are held together with ligaments that form the joint capsule. Common injuries to the elbow joint include fractures of the bony structures contributing to the joint. These two tendons are important to understand because they are common locations of tendonitis.
