Abstract: PURPOSE: A medical device capable of maintaining x-ray imaging efficiency and a preparation method thereof are provided to maintain x-ray imaging efficiency while nearly maintaining mechanical properties and biocompatibility. CONSTITUTION: A medical device comprises a medical device and a layer combined on the medical device. The layer combined on the medical device is composed of either contrast material for x-ray imaging or a composite of contrast material for x-ray imaging and a biocompatible polymer. The medical device is selected from among a plate for fixing a bone or treating bone fracture, a screw, and a pin. The biocompatible polymer is one or more kinds of material which are selected from among poly (lactic acid), poly (glycolic acid), poly (ethylene glycol), poly (trimethylene carbonate), poly (caprolactone), poly (dioxanone), poly (methyl methacrylate), poly ethylene, polytetrafluoroethylene, polyvinyl chloride, polydimethysilioxane, polyurethane, and copolymers thereof.
