PROSTHESIS AND INTERNALLY-FIXED SPLINT FOR TREATING BONE FRACTURE

摘要

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an artificial prosthesis, and more particularly, to an artificial prosthesis that significantly improves a bone fusion force between a natural bone of a human body and an artificial prosthesis. Specifically, the present invention provides an artificial prosthesis comprising: a body portion forming an outer shape of the artificial prosthesis; And a body unfolding surface portion covering the outer surface of the body portion and having a porous surface structure composed of a plurality of fine grooves and contacting and fusing the natural bone of the human body, And a cell filling portion communicating with the inflow opening and formed in an inner thickness direction of the unfused surface portion and being a space in which human cells are grown and filled, Wherein the cell filling portion comprises, at least in part, a reverse gradient side portion formed in an inner thickness direction of the unfused surface portion.
