An artificial bone includes a bone-shaped hollow metal body confining a
sealed space and having two opposite closed ends, and a porous structure
disposed in the sealed space. A method for making the artificial bone
includes the steps of: positioning a metal tube in a bone-shaped mold
cavity of a mold, hydro-forming the metal tube into a bone-shaped hollow
tube in the bone-shaped mold cavity by injecting a high pressure fluid
into the metal tube, disposing a crumple of metal wire into the
bone-shaped hollow tube, depositing a metal coating on the metal wire and
an inner surface of the bone-shaped hollow tube to form a porous
structure in the bone-shaped hollow tube, and sealing the bone-shaped
hollow tube.
