Olecranon process: During adolescence

During adolescence, an elbow injury can damage the growth plate, or olecranon underdevelopment may occur after repeated microtrauma (especially in athletes). The olecranon (olecranon process) is the large, superior projection on the proximal part of ulna. It curves anteriorly at its top, forming a prominent tip which is accommodated by the olecranon fossa of humerus during forearm extension. The olecranon process is the posterior summit of the elbow joint, providing the attachment for the triceps muscle. Complex multidirectional forces often occur in olecranon fractures. The olecranon articulates with the humerus via the olecranon fossa on the humerus, which is situated over the posterior surface of the humerus. It is continuous with the coronoid process of the ulna via the trochlear or semilunar notch anteriorly.
