Objective To compare the clinical effect of the Slide-Traction plate and common plate in the treatment of epiphyseal injury and adjacent fracture of distal femur,and providing experiment and clinical data for safe clinical practice in the Slide-Traction plate.

In order to discuss the possibility of stainless steel as bone of concrete instead of plain carbon steel,the corrosion behavior of the plain carbon steel and stainless steel in simulated concrete pore solutions with different chloride ion concentrations and pH values were studied by potentiodynamic polarization and alternating current impedance.
