A metal bone supporter for medical bone substitute including a supporter and a connector component which are functionally and structurally designed according to anatomical data and biomechanical data. The titanium alloy powders in the device are able to be scanned, melted and molded through electron beams, to form a cylinder with the strength and elastic modulus similar to cancellous bones of the human body. The supporter component is a porotic spongy body structure with threads on an end, and porous structure forms a rough surface. The connector component is made with a smooth surface and a dense solid mass inside, a thread on an end, and is connected to the supporter component as a removable body. The porous structure enables bone growth, and the device has a high surface friction coefficient, and has a stable structure and mechanical properties are similar to bones.
