摘要：
PROBLEM TO BE SOLVED: To achieve a bone reconstruction member having enough strength for application to a large bone defective site.SOLUTION: A bone reconstruction member 110 is composed of a three-dimensional mesh-like structure that has a shape corresponding to the shape of a bone defective site 121, and has an average pore diameter of 100 μm or more and 600 μm or less and a porosity of 60% or more and 90% or less. The three-dimensional mesh-like structure is composed of titanium or titanium alloy, with the inside of the structural skeleton being hollow.SELECTED DRAWING: Figure 1【課題】大きな骨欠損部位にも適用可能な十分な強度を有する骨再建部材を実現できるようにする。【解決手段】骨再建部材１１０は、骨欠損部位１２１の形状に対応した形状を有し、平均孔径が１００μｍ以上、６００μｍ以下で、空孔率が６０％以上、９０％以下の３次元網目状構造体からなる。３次元網目状構造体は、チタン又はチタン合金からなり、構造骨格の内部が中空である。【選択図】図１
