Wedge fracture, fragmentary wedge

These are multifragmentary diaphyseal fractures of the tibia. Once the fracture is reduced, there is contact between the proximal and distal fragments.
The wedge component of this fracture is, itself, also fractured in two or more fragments.
They are caused by high-energy impact.
These fractures are classified as AO/OTA 42B3 fractures.
