PROBLEM TO BE SOLVED: To stabilize the fixing/bearing power to a bone including immediately after a replacement therapy is executed by mixedly providing arch-like lugs and through holes on the outermost layer of a porous body stacked with many metal material thin sheets bored with many through holes and having no organism injuring property to form an artificial prosthetic member. SOLUTION: Metal thin sheets 1, 2... bored with many holes H and having no organism injuring property are stacked in sequence to form a layered- structure porous body S, and an artificial prosthetic member is constituted. Many arch-like lugs N are formed by punching at the desired position of the thin sheet 1 on the outermost layer to be kept in contact with a bone. Through holes H1 with lugs are provided on the lugs N mixedly with independent through holes H. Independent arch-like lugs N1 having no through holes H1 may be provided. The arch-like lugs N are coupled with the bone immediately after a replacement therapy, the positional drift and fine movement of the artificial prosthetic member are prevented, and the fixing/bearing power is stabilized. |
