	Bone fracture - Wikipedia, the free encyclopedia
		A bone fracture is a medical condition in which a bone becomes cracked, splintered, or bisected as a result of physical trauma.
		A greenstick fracture occurs because the bone is not as brittle as it would be in an adult, and thus does not completely fracture, but rather exhibits bowing without complete disruption of the bone's cortex.
		To this end, a fractured limb is usually immobilized with a plaster or fiberglass cast which holds the bones in position and immobilizes the joints above and below the fracture.

	Fracture - Wikipedia, the free encyclopedia
		The word fracture is often applied to bones of living creatures, or to crystals or crystalline materials, such as gemstones or metal.
		Depending on the substance which is fractured, a fracture reduces strength (most substances) or inhibits transmission of light (optical crystals).
		In amorphous solids, by contrast, the lack of a crystalline structure means that any direction may be considered a cleavage plane; the result is a conchoidal fracture, with cracks proceeding normal to the applied tension.

	Tibial Fracture- Health Encyclopedia and Reference
		A closed fracture is a fracture in which the skin of the lower leg is not broken.
		An open fracture is classified according to the degree of skin disruption, and whether or not there is significant soft tissue loss, blood vessel disruption, or gross contamination.
		A fracture of the tibia is serious because this bone heals slowly and sometimes poorly because of the sparse blood supply in some areas of the bone.

	Fracture -- eCureMe.com
		In an impacted fracture, the pieces are jammed together by the force of the injury, and we may not see a fracture line because the bony pieces are pushed into each other.
		Fractures usually are splinted or casted to place the injured part at-rest, avoiding movement of the fracture pieces while they are healing.
		In some minor fractures where a deformity does not have to be corrected, such as a minor fracture of a toe, some simple method might be used to hold the pieces in-place.

	Pelvic fracture
		A stable fracture is one in which the pelvis remains stable and involves one break-point in the pelvic ring with minimal hemorrhage.
		An unstable fracture is one in which the pelvis is unstable with two or more break-points in the pelvic ring with moderate to severe hemorrhage.
		Depending on the severity of the fracture, other imaging procedures may be required as well, such as contrasting studies involving the injection of a radioactive dye; the pictures can be used to evaluate organs and structures in the pelvic area, such as the urethra, bladder, and blood vessels.

	FRACTURE MECHANICS (Site not responding. Last check: 2007-10-07)
		Fracture is a very complex process that involves the nucleation and growth of micro and macro voids or cracks, mechanisms of dislocations, flip bands, and propagation of microcracks, and the geometry of the material.
		The energy necessary to fracture the test piece is directly calculated from the difference in initial and final heights of the swinging pendulum (Figure 7.).
		A fatigue fracture will have two distinct regions; One being smooth or burnished as a result of the rubbing of the bottom and top of the crack(steps 1 and 2); The second is granular, due to the rapid failure of the material.

		In the U.S., the cost of hip fracture is approximately 7 billion dollars annually, and hip fracture is the second most common cause of admission to nursing homes, accounting for some 60,000 admissions each year.
		With a pelvic fracture, this may be achieved by tying the legs together at the ankles and knees and transporting on a firm surface (backboard).

	MedlinePlus Medical Encyclopedia: Bone fracture repair
		Bone fracture repairs are surgical procedures to realign and stabilize broken bones (fractures) with plates, nails, screws, or pins.
		If examination of the fracture shows that a quantity of bone has been lost as a result of the fracture, especially if there is a gap between the broken bone ends, the surgeon may decide that a bone graft is essential to avoid delayed healing.
		This is especially true of fractures that involve joints, as misalignment of joint surfaces may contribute to the development of arthritis.
