< Topic >Offer the trial in plant component which is used for the surgical operation for substituting the joint professional thesis in the joint with the long bone and the other bone.SolutionsIn order to contact the inner wall of the cavity in the excision aspect of the long bone in the territory of the extension and the frame work edge to intracavity, the frame work end which can be arranged is included, the trial in plant component. This frame work end had the part of the inserting section/the socket assembly body, the part of this assembly body, had the part to which this assembly body corresponds, to insert, it has reached the point where it engages in the component. The inserting section/the socket assembly body has demarcated the assembly body axis, it confronts the width of the frame work end in the surface where it is measured in general alongside the internal axis, ratio of length of the frame work end which is measured with the surface and the underside alongside the assembly body axis, is approximately 1.0 or less. The plane surface which is demarcated the plane surface which is demarcated by the peripheral edge of the surface of the frame work end and by the peripheral edge of the underside angle with, is below approximately 30 degrees.< Selective figure >Figure 2【課題】長骨と他の骨との間の関節における関節プロテーゼの置換のための外科手術に用いるトライアルインプラントコンポーネントを提供すること。【解決手段】長骨の切除面で腔内への延び、骨幹端の領域において腔の内壁に接触するように、配置できる骨幹端部を含む、トライアルインプラントコンポーネント。この骨幹端部は、差込み部/ソケット組立体の部分を有し、この組立体の部分は、かかる組立体の対応する部分を備えた嵌め合いコンポーネントに係合するようになっている。差込み部/ソケット組立体は、組立体軸を画定しており、概ね内外軸に沿って測定される上面での骨幹端部の幅に対する、組立体軸に沿って上面と下面との間で測定される骨幹端部の長さの比が、約1.0以下である。骨幹端部の上面の外周縁によって画定されている平面と下面の外周縁によって画定されている平面との間の角度が、約30度以下である。【選択図】図2
