42-B3   Diaphyseal fracture with nonreconstructible wedges

42-B3 are diaphyseal fractures with one or more non-reconstructible wedges.

Radiographs of a 6-year-old domestic shorthair cat who sustained an unknown trauma. The radiographs show a 42-B3 fracture of the proximal diaphysis.

42-B type fractures are typically caused by a combination of bending and compression forces.

They may occur after a fall from height, being kicked or following blunt trauma. Depending on the amount of energy causing the fracture, there may be more or less comminution.

Clinical signs observed in 42-B fractures are:

• Swelling of the region
• Abnormal movement in the tibia shaft
• Pain
• Non weight bearing on the limb

Craniocaudal and lateral radiographic views are needed.
