Types

The diaphyseal fractures of the long bones are divided into three Types (A, B and C), indicative of an increasing severity.


Simple fracture. A single linear disruption of the diaphyseal circumference that delimits two fragments.	Wedge fracture. There is a wedge shaped fragment. Once the fracture is reduced, there is contact between the two main fragments.	Complex fracture. A fracture with several intermediate fragments. After reduction, there is no contact between the main fragments.

The fractures of the proximal and distal segments are divided into three Types (A, B and C), indicative of an increasing severity.


Extra-articular fracture. The fracture line may be either metaphyseal or epiphyseal but does not involve the articular surface.	Partial articular fracture. The fracture line goes through the articular surface but a portion of it remains united to the diaphysis.	Complete articular fracture. The fracture line goes through the articular surface and separates it completely from the diaphysis.s.
