This article introduced the investigation and evolvementof close reduction for fracture and discussed their mechanism from thetact reduction for fracture,dynamical system of muscle,reduction andpercutaneous fixation,the fixator for frature reduction and ligamenttaxis,in order to provide the academic foundation of science forcatagmatic treatment and guide the clinical treatment for fracture.Science and techonology has rapid development recently and CANS hasbeen applied to orthopaedic surgery gradually.I believe that peoplewill invent a digital criterion about the reduction tact for fracturein the future. |
