1. Green - stick fracture (young animal.. One side broken and other side bent)
2. Oblique Spiral Multiple Maintain in length and a ligament prevent rotation
3. Acc to stability
3.1. Stable
3.2. Unstable
4. Incomplete
4.1. Star fracture ( central point+ radiating fissure+ animal kick)
4.2. Fissure fracture ( single or multiple fissure in bone.. Mature animal)
4.3. Deferred fracture " subperiosreal" : separation of bone fragment without displacement.. Periosteum intact
4.4. Splintered or partial fracture : separation of bone fragment with displacement.. Periosteum rupture)
5. Complete
5.1. acc to soft tissue damage
5.1.1. Simple " closed" fracture: skin intact
5.1.2. Compound *open* fracture
5.1.2.1. 1: communication bet fracture and skin wound 2: three degree # first degree: skin wound from inside # second degree: skin wound from outside + soft tissue injury + contamination # third degree: skin wound from outside+ extensive tissue damage + bone loss + gross contamination
5.1.3. Complicated fracture: facial wound complicated by fracture of the frontal bone with exposure of the concho frontal sinus
5.2. Transverse green- stick Impacted Angular deformity
5.3. acc to number of fracture lines
5.3.1. 1: single 2: comminuted 3: multiple *segmental*
5.4. Acc to direction of fracture lines
5.4.1. 1: transverse 2: oblique 3: spiral 4: longitudinal
5.5. Acc to location of fracture *part of bone involved*
5.5.1. 1: diaphyseal fracture *fracture shaft of the bone*
5.5.2. Metaphyseal fracture "fracture of adult bone "proximal or distal"
5.5.3. Physeal fracture *young animal*
5.5.3.1. Type 1: fracture physis Type 2: fracture physis + distal diaphysis Type 3: fracture physis + epiphysis (articular) Type 4: fracture physis + epiphysis + distal diaphysis Type 5: crushing injuries of physis not visible radiographically + physeal function ceases
5.5.4. Epiphyseal fracture
5.5.4.1. 1: fracture epiphysis of mature bone 2: Articular... True articular... Condylar
5.6. Acc to displacement of bone fragment
5.6.1. 1: transverse fracture 2: longitudinal displacement fracture 3: overlapped displacement fracture 4: overlapped displacement fracture 5: angular fracture 6: avulsed fracture 7: impacted fracture 8: compressed fracture 9: depressed fracture
