Fracture: A break in bone or cartilage. Although usually a result of trauma, a fracture can be the result of an acquired disease of bone, such as osteoporosis, or of abnormal formation of bone in a congenital disease of bone, such as osteogenesis imperfecta ('brittle bone disease'). Fractures are classified according to their character and location (for example, greenstick fracture of the radius).
