<p>PURPOSE:To facilitate adaption in size and shape to a bone missing part by allowing the end of an enclosing member made from a sheet material to stretch to outside an artificial bone member, and forming a cylindrical chamber for insertion of the end of the bone which is to be joined with the artificial bone member. CONSTITUTION:An artificial bone composite material 1 is composed of an enclosing member 2 formed cylindrically and an artificial bone member 3 clathrated to its inside. The artificial bone member 3 is processed so as to have a shape which suits the size and shape of the bone to be repaired, and an autoplastical bone 5 is transplanted to a recess formed in a part of the artificial bone member 3, to build a composite body. The enclosing member 2 consists of a mesh fabric made from polyethylene fiber which is wound on the artificial bone member 3, or is sewn into a cylindrical form which suits accommodating the artificial bone member. At the end of this enclosing member 2, a cylindrical chamber 4 is formed as stretching to outside the artificial bone member 3 for the purpose of inserting the end part of the residual bone when the missing part of rib or a collarbone is to be repaired, wherein the end of the residual bone is joined in this cylindrical chamber 4 with the end of composite body of the artificial bone member and autoplastical bone. The joint is enclosed fast by the surrounding enclosing member.</p> |
