Abstract
A hip joint femoral prosthesis has a rod, the proximal end of which has a cross-section of oval shape and a surface area increasing towards the proximal end. At least one wall of the proximal end includes alveoli therein hollowed out so as to present a maximum depth on their side towards the proximal end. The alveoli are of a circular or semi-circular shape and intersect, thereby providing a surface which improves the stability and anchoring of the prosthesis into the femur.
