The invention relates to an osteosynthetic anchoring member comprising a longitudinal shaft extending along a longitudinal axis having a front shaft portion and a rear shaft portion, the front shaft portion insertable into a bone and comprising anchoring means for fixating the shaft in the bone and the rear shaft portion comprising anti-rotation means for permitting the rear shaft portion to be received in an implantable bone plate or a connecting member and to be secured against rotating about the longitudinal axis. The anchoring means are capable of being extended orthogonally with respect to the longitudinal axis of the shaft, and the rear shaft portion comprises tension means for extending the anchoring means to enable the anchoring member to be fixated within the bone. Also disclosed is a fixation device including such an anchoring member for fixating fractured femoral heads comprising the anchoring member to be fixated within the fractured femoral head, a plate to be screwed to the main part of the femur including a sleeve in which the anchoring member may be received and wherein it is displaceable coaxially to the longitudinal axis, and a compression bone screw to be screwed into the internal screw thread of a spindle.
