Femoral prosthesis having an anchoring system with screwed metaphysis and blocked diaphysis, characterised in that: a) the neck 2 ending in a truncated cone 3, forming a relatively trapezoidal part 1, receives the heads 4 of small diameter which are generally made of a ceramic compound or metal, b) the cervico-diaphysial angle is normally between 135 and 120 DEG , and c) the prosthetic shaft, which is to have a self-locking morphology and to exist in several sizes, comprises a metaphysial upper part 6b, a self-locking lower part 6a extended via a strictly conical zone 7 receiving the metaphysial bushing 9. <IMAGE>
