ABSTRACT:
Given a hip joint femoral prosthesis having a shaft, a spherical head and a connecting part between the shaft and the head. Disposed at the proximal end of the shaft and in the head in each case is a conical boring. Located at the shaft side end and at the head side end of the connecting part is a socket cone cooperating with each conical boring. The longitudinal axis of the first socket cone and the longitudinal axis of the second socket cone of the connecting part intersect at a predetermined angle 0.ltoreq..beta..ltoreq.50.degree. (zero is less than or equal to beta and beta is less than or equal to 50.degree.), in order to be able to adapt better the relative position of the head to the shaft, individually, to the conditions of the patient.
