Low energy olecranon fractures:
- most commonly occur in elderly patients, and result from indirect trauma;
- fracture results from a sudden pull of both the triceps and brachialis muscles;
- fracture begins at midpoint of trochlear notch and extends distally to enter semilunar notch;
- amount of fracture displacement is influenced by the pull of the triceps muscle as well as any disruption of triceps aponeurosis or periosteum;
High energy fractures:
- olecranon fractures in younger patients are more often high energy injuries, resulting from direct trauma;
- often there is associated comminution or concomitant ulnar shaft fracture;

The human's unique prehensile skill largely depends on the integrity of the bones, ligaments, and muscles around the elbow joint. The elbow not only bends the arm but also permits pronation and supination of the hand. Fractures of the olecranon are common and are usually detected easily.
