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:
Craniocaudal and lateral radiographic views are needed.
