Which type of fracture occurs as the result of a severe twisting motion such as in a sports injury?

With a severe twisting motion, a bone may sustain a spiral fracture or a torsion fracture. Spiral fractures are associated with a rotating force or a torque with energy enough to split or fracture the bone. This fracture is common to the pediatric age group, especially in school age children wherein accidents during jumping and running often produce this kind of injury.

Blood transfusions were rarely done and often fatal; they were outlawed until the nineteenth century.
