An orthopedic implant with a polymer-wrapped metal prosthesis, comprising a metal implant body and a high-molecular layer wrapping the surface of the implant. The orthopedic implant is formed by wrapping the surface of a metal implant body material with an anti-corrosion organic high-molecular material, such that a metal implant is prevented from being corroded by human body liquid. An organic high-molecular material wraps between two metal implants in contact with each other, so that contact between metal and metal is prevented, thereby inhibiting electrochemical reactions caused by the contact between metal and metal, and further reducing adverse reactions on a human body caused by dissolution of metal ions. Meanwhile, the existence of a high-molecular interface aids in enhancement of locking between metal implants, prevents and reduces slight movement, and accelerates operation healing. |
