42-B1 are diaphyseal fractures with one large reconstructible wedge.
8-year-old MC DSH that was HBC.
Pre-operative radiographs show complete, comminuted, oblique fracture between the middle and distal thirds of the right tibia with caudal, proximal, and lateral displacement. Transverse fracture between the middle and distal thirds of the right fibula and an oblique fracture of the proximal fibula.
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
Non weight bearing on the limb
Craniocaudal and lateral radiographic views are needed.
