An elbow prosthesis comprising a condylar portion (118) having a humeral bushing (103) for receiving a hinge pivot (106) along an axis (112) of the hinge； An ulna component (104) comprising an ulna bearing (105) and an ulna body (107) configured to be coupled together and in an interlocked state, the condylar portion (118) and the ulnar bearing (105) Are configured to articulate with each other about the axis (112) of the hinge in a state where the joints are joined, the ulnar bearing (105) includes an ulna hinge hole (145), and the ulna main body The part (107) is in the coupled state an ulna coupling hole (154) which is aligned with the ulna hinge hole (145) along the axis (112) of the hinge 43), the hinge rotation shaft (106) can be fixedly attached to the ulnar connection hole (143), and the ulnar connection hole (143) and the ulnar hinge hole (145) are the hinge rotation. For insertion of the shaft (106), with the joint joined, it is further aligned with the humeral bushing (103) along the axis (112) of the hinge. An elbow prosthesis can be used for total elbow joint replacement, and during surgery, the surgeon can connect or disconnect the restraint utilizing the connection of the body portion of the ulnar stem and / or the humeral stem. You can choose from the type. By means of additional modularity, cementation or cementless fixation of the stem can also be selected. The modularity and adjustability of the present invention have many advantages.【課題】肘プロテーゼであって、ヒンジの軸（１１２）に沿ってヒンジ回転軸（１０６）を受け入れるための上腕骨ブッシング（１０３）を有する顆部（１１８）を備える上腕骨コンポーネント（１１９）と、互いに連結し連結状態となるよう構成される、尺骨ベアリング（１０５）及び尺骨本体部（１０７）を備える尺骨コンポーネント（１０４）と、を備え、前記顆部（１１８）と前記尺骨ベアリング（１０５）とは、関節が接合された状態で前記ヒンジの軸（１１２）を中心とし互いに関節接合するよう構成されており、前記尺骨ベアリング（１０５）は、尺骨ヒンジ孔（１４５）を備え、前記尺骨本体部（１０７）は、前記連結状態で前記ヒンジの軸（１１２）に沿って前記尺骨ヒンジ孔（１４５）と位置合わせされる尺骨連結孔（１４３）を備え、前記ヒンジ回転軸（１０６）は、前記尺骨連結孔（１４３）に固定して取り付け可能であり、前記尺骨連結孔（１４３）及び前記尺骨ヒンジ孔（１４５）は、前記ヒンジ回転軸（１０６）の嵌入のために、前記関節が接合された状態で、前記ヒンジの軸（１１２）に沿って前記上腕骨ブッシング（１０３）に更に位置合わせされる。【解決手段】肘プロテーゼは全肘関節置換術に用いることができ、そ
