This invention, the transposition territory (34), the bearing body (38) with the shaft (32) with is arranged between the bearing body (38), the shaft (32), and the transposition territory (34) in regard to the component of the humerus of the shoulder joint artificial organ which is included. The transposition territory (34) one surface, the sclerite and/or the attaching kimono of the muscle, and/or has the structure which does the form of the spine which makes the tendon come in contact in wide scope. The spine (48), in order the transposition territory (34) to be distributed discretely on the surface, it is arranged, at the same time basically it is arranged in proximal - distal (2036) direction and peripheral direction.本発明は、軸受体(38)、シャフト(32)、および転位領域(34)を含む肩関節人工器官の上腕骨のコンポーネントに関し、転位領域(34)は、軸受体(38)とシャフト(32)との間に配置される。転位領域(34)の1つの表面が、広範囲において、骨片及び/若しくは筋肉の付着物、並びに/又は腱を付着させる突起部の形態をした構造を有する。突起部(48)は、転位領域(34)表面上に離散的に分布するように配置され、且つ基本的には近位-遠位方向及び外周方向において配置されている。
