摘要
Abstract
Four configurations of Combinable External Fixation(CEF) devices used for curing of fracture femur with the fracture gap cross the middle of the femur were tested to determine their biomechanical feature, such as the strain distribution of the femur-Fixator compound systems, the fixator stiffness. There were some differences between configurations of CEF in all modes of loading with respect to strain-distribution and stiffness. It is proved that the stiffness of the femur with CEF is stronger than that of intact femur. And the strain-distribution of the femur with CEF is also smoother than that of femur without CEF. In the stable fixation, because the load still go through the diaphysis, the CEF has a little stress shielding. And so the CEF can provide a better condition of the new bone formation. These data may be useful in developing the CEF for a particular clinical situation.关键词
