Joint member for a hip prosthesis having a joint head, a supporting portion including a supporting surface co-operating with a corresponding supporting surface on the proximal femur and fixation means members for securing joint head and supporting means portion to the femur, characterized in that a shankless and block-like supporting member (4, 41) includes at least a supporting surface (10, 11, 43, 44) disposed adjacent the joint head (2, 40) such that the corresponding femur supporting surface (7'', 7') is adjacent the proximal medical femural cortex, in that further retaining means members (15, 21) are provided coacting with the proximal femur (7) and engaging the supporting member (4) through a bore (13') in the femur supporting surface (7'') in order to exert a tensile force on the supporting member (4) laterally to press the supporting surface (10, 11) against the femur supporting surface (7'', 7'), and in that the supporting member (4) and/or the retaining members are prevented from rotation about the axis of the femur neck.
