Structure Edit. The ulna is broader close to the elbow, and narrows at it approaches the wrist. Close to the elbow, the ulna has a bony process, the olecranon process, a hook-like structure that fits into the olecranon fossa of the humerus.This prevents hyperextension and forms a hinge joint with the trochlea of the humerus.There is also a radial notch for the head of the radius, and the ulnar tuberosity to which muscles attach. Close to the wrist, the ulna has a styloid process.his prevents hyperextension and forms a hinge joint with the trochlea of the humerus.
