Bone prosthetic material

Abstract

Disclosed is a bone prosthetic material that is capable of preventing a plurality of members from being disconnected due to a difference in the coefficient of thermal expansion, and that is also capable of facilitating the work to insert them while ensuring the bone replacement capability. Provided is a bone prosthetic material comprising: a plurality of prosthetic material pieces and which include bioabsorbable materials having different absorption rates, and which are adjacent and connected to each other; and a joint which is provided in a connecting surface between these prosthetic material pieces and, and which is mutually combined to connect the prosthetic material pieces and while limiting displacement in directions along the connecting surface.

Dependencies are inferred from the claim text.
