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.
There are two main types of fracture fixation: internal and external. All internal and external fixation methods that allow appreciable interfragmentary movement under functional weight bearing are considered flexible fixation. Techniques that use compression are considered rigid fixation (1â6). The article describes current approaches, techniques, instrumentation and complications related to fracture fixation, with discussions of conservative fracture treatment, external and internal fixations, and bone grafting.
