A hip joint prosthesis adapted to be implanted in a hip joint of a human patient, where said hip joint prosthesis has a longitudinal axis (L) that extends in a proximal-distal direction when it is implanted, where the hip joint prosthesis comprises: - a first area comprising a first material or part of material, - a second area comprising a second material or part of material, - a third area comprising a third material or part of material, - a fourth area comprising a fourth material or part of material, - a fifth area comprising a fifth material or part of material, wherein said first, second, third, fourth and fifth materials or parts of materials are connected to each other by means of net attractive forces, and where said hip joint prosthesis has a longitudinal axis (L), in the distal direction a proximal, where said first, second, third, fourth and fifth areas are located consecutively along said longitudinal axis (L) where the first area is proximal to the second area, characterized in that: - said first material or parts of said first material are more elastic than said second material or parts of said second material, - said second material or parts of said second material are more elastic than said third material or part of said third material, - said third material or parts of said third material are more elastic than said fourth material or parts of said fourth material, and - said fourth material or parts of said fourth material are less elastic than said fifth material or parts of said fifth material, such that the difference in elasticity affects elasticity of the hip joint prosthesis along the longitudinal axis (L) thereof.Una prótesis de la articulación de la cadera adaptada para ser implantada en una articulación de la cadera de un paciente humano, donde dicha prótesis de la articulación de la cadera tiene un eje longitudinal (L) que se extiende en una dirección proximal-distal cuando está implantado, donde la prótesis de la articulación de la cader
