In an injury to the olecranon, the tendons of the triceps and biceps should be considered for possible rupture primarily due to their anatomical and functional roles in elbow movement. The olecranon is the bony prominence of the ulna that serves as the attachment point for the triceps muscle. When the elbow is subjected to trauma, such as a fracture or dislocation, the tension and forces exerted on the triceps muscle can lead to a rupture of the tendon.

The triceps tendon is responsible for extending the elbow joint, and a rupture would significantly impair this function. Meanwhile, the biceps tendon is involved in flexing the elbow and can also be affected, particularly if the injury compromises the surrounding structures, though it is less directly associated with the olecranon.

Understanding the primary muscles involved in elbow mechanics is essential for diagnosis and treatment following an olecranon injury. The other options present tendons that do not have a direct association with the olecranon and are not typically at risk in such injuries. The brachialis and biceps, though significant in elbow dynamics, do not primarily attach to the olecranon. Similarly, the subscapularis and deltoid, as well as the sup
