Generally are the result of high energy trauma. The degree of comminution is usually indicated. Segmental Fractures Also called multiple fracture. Compression Fractures A fracture in which cancellous bone collapses upon itself. As the name implies, these fractures are the result of compressive forces.
Spinal fractures are the most common site for compression fractures to occur.
The fracture involves the articular cartilage and subchondral bone. If a fracture involves the articular surface it greatly influences the method and timing of the repair, as well as the prognosis. Thus it is important to describe it as such.
