1 The prothrombin or vitamin Kâdependent group includes factors II, VII, IX, and X. 2  The fibrinogen group includes factors I, V, VIII, and XIII. 3  They are the most labile of the factors and are consumed during the coagulation process.
It is important to classify the type of fracture, because some fractures are more difficult to treat than others. Intra-articular fractures, open fractures, comminuted fractures, and displaced fractures (when the broken pieces of bone do not line up straight).are more difficult to treat, for example. Sometimes, the other bone of the forearm (the ulna) is also broken. This is called a distal ulna fracture.
The severity of a fracture can vary. For example, a simple twist of the ankle may result in a single crack in the bone. The force of a head-on car collision, however, may result in the bone being shattered (comminuted fracture). Similar fractures can result from different mechanisms.
