To provide a selectively expanding spine cage with enhanced bone graft infusion.SOLUTION: A selectively expanding cage 100 comprises a body 106, the body defining a center cavity 114 configured to communicate with a space between vertebrae in order to infuse a bone graft material thereinto when receiving and arranging, in the space between the vertebrae, the body including a bone graft material supply port communicating with the center cavity. On the body, an extendable member capable of being extended along an extension axis from a non-expansion height to an expansion height can be mounted. The body also comprises a connector arranged so as to be coupled with an insertion tool.SELECTED DRAWING: Figure 4-1 【課題】骨移植片注入を高めた選択的な拡張式脊椎ケージを提供する。【解決手段】選択的に拡張するケージ１００は、本体１０６を備え、前記本体は骨移植片材料を受け入れかつ前記椎骨間の空間に配置するとき、そこへ前記移植片材料を注入するために前記椎骨間の空間と連通するように構成された中心キャビティ１１４とを画成し、前記中心キャビティと連通した前骨移植片材料供給ポートを含む。さらに、前記本体は、非拡張高さから拡張高さまで伸長軸に沿って伸長可能である、伸長可能部材を装着できる。さらに本体は、挿入具に結合するために配置されたコネクタを備えている。【選択図】図４−１
