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.
humerus, regardless of the level or number of fracture lines, in which no segment is displaced more than 1cm or angulated more than 45Â°. Two-part fractures The two-part fracture includes those proximal humeral fractures with a single displacement at the anatomic neck, surgical neck, lesser tuberosity, or greater tuberosity. The fracture is named by the structure that is displaced (Two-part surgical neck fracture). Three-part fractures The three-part fracture includes all proximal humeral fractures with a displaced surgical neck and either a greater or lesser tuberosity displacement fracture. Four-part fractures Four-part fractures are proximal humeral fractures with three displaced, fractured segments including both tuberosities and typically the surgical neck.
