The Mechanics of Long Bone Fractures.
Abstract
Fractures of long bones are a common clinical finding in human trauma situations. These include injuries which are sustained during automotive and aircraft crashes, parachute, landings, and aircraft ejection. Irrespective of the trauma-producing environment, extremity fractures are related to the loading state and the rates of application of injury forces, as well as local geometrical and mechanical properties of bone structure. The objectives of this current research are: to gain insight into the fracture behaviour of long bones under singular and combined states of loading through a spectrum of loading rates, and to characterize the geometric and mechanical properties of long bones by non-destructive means. Using a modified Instron Materials Test System fresh paired canine long bones are being studied under torsional and torsion-compressive states of loading through a spectrum of loading rates. Fracture behaviour is characterized by the torque and energy to failure, angle of twist, fracture type and location.
