Type 2 - epiphyseal and metaphyseal fracture
- Direct trauma → metaphysis and epiphysis fracture, with metaphyseal fragment often extending into the elbow joint.
Type 3-5 - olecranon body
- Trauma (> yearling, adult) → fracture olecranon diaphysis → distraction by triceps, usually along the caudal cortex because cranial portion secured by joint capsule.
