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 nasal bones are the most commonly fractured bony structures of the maxillofacial complex.See the images below. Lateral radiographic view of a displaced nasal bone fracture in a patient who sustained this injury because of a punch to the face during a hockey game. Lateral radiographic view of a nasal bone fracture in an elderly patient who fell forward on her face as a result of syncope. Marked comminution is present. The nasal bone's protruding position coupled with its relative lack of support predisposes it to fracture.
