A comminuted fracture is one in which the bone is crushed or splintered into many pieces.Ĭ. A greenstick fracture is an incomplete fracture in which one side of the bone is broken and the bone is bent.ī. Some types of fractures are briefly described in the following paragraphs.Ī. Therefore, anytime you suspect that a fracture may be present, treat the injury as though you knew the fracture existed. A nondisplaced fracture may be difficult to identify without an x-ray.
High-energy impacts, such as being hit by a speeding vehicle or by a bullet, may produce multiple fractures and cause severe damage to surrounding tissues.Ī fracture may be displaced (bone moved out of normal alignment) or nondisplaced (bone remains in normal alignment). Certain diseases, such as cancer, can weaken bones and make them easier to break. Fatigue (stress) fractures can result by repeated stress, such as a stress fracture of the foot during a long march. A fracture can also result from a limb being twisted (fracture and dislocation may result) or from powerful muscle contractions (such as may occur during a seizure). Examples of fractures.įractures may be caused by a direct blow to the body (such as being hit by a vehicle) or by indirect force that results in a fracture away from the point of impact (such as a hip fracture resulting from a person landing on his knee after a hard fall).
#Complete bone fracture skin
Infection is also a major concern since the skin is broken.
There is a risk of shock from blood loss. An open fracture usually results in more blood loss than does a closed fracture since the blood can escape through the open wound. If an open wound is caused by a fractured bone, the bone may remain visible or it may slip back below the skin and muscle tissues. The source of the penetration may have been the end of a fractured bone (see figure 1-3B) or a foreign object, such as a bullet, which penetrated the skin and fractured the bone (see figure 1-3C). An open fracture is one in which the skin is broken (penetrated). A closed fracture may result in significant loss of blood due to internal bleeding (bleeding into surrounding body tissues or into a body cavity). A closed fracture (see figure 1-3A) is a fracture in which the skin is not broken. If a rib is fractured in two places, the bone segment between the two fractures may “float” and damage an organ (such as the heart or a lung) or a major blood vessel (such as the aorta).Ī. Complete fractures are also dangerous because the sharp ends of the fractured bone can injure muscle tissues, nerves, and blood vessels. A fracture of a large bone like the femur can result in a significant loss of blood that, in turn, can result in hypovolemic shock.
#Complete bone fracture crack
The break may only be a crack in the bone (incomplete fracture) or the bone may be broken into two separate parts (complete fracture).
