Bone tissue engineering (BTE) is an evolving field at the intersection of materials science and bioengineering, focused on the development of bone substitute materials and diagnostic methods in orthopedics. At present, physicians ...
Cell differentiation is a widely studied phenomenon forming the basis of all developmental processes including fetal growth and bone fracture healing. A series of recent studies indicates the emerging role of chondrocyte-to-osteoblast ...
(Medical Xpress)—Researchers from South Korea have shown, in preliminary clinical trials of 53 patients, that after a year their magnesium-calcium-zinc orthopedic implant spurs new bone growth by mimicking the body's calcification ...
"Break a leg!" is a welcome blessing of good luck, but who wants to hear that they have actually broken a bone? What's worse, fractures that are displaced or complex require surgery and possibly lengthy recovery times while ...

A fracture is the (local) separation of an object or material into two, or more, pieces under the action of stress.
The word fracture is often applied to bones of living creatures (that is, a bone fracture), or to crystals or crystalline materials, such as gemstones or metal. Sometimes, in crystalline materials, individual crystals fracture without the body actually separating into two or more pieces. Depending on the substance which is fractured, a fracture reduces strength (most substances) or inhibits transmission of light (optical crystals).
A detailed understanding of how fracture occurs in materials may be assisted by the study of fracture mechanics.
