A method for determination of the mobility of a hip joint prosthesis is proposed, comprising a bearing cup that can be inserted in the hip bone and a prosthetic shaft that can be inserted in the femur and is pivotally mounted by a spherical joint surface in the bearing cup, which is characterised in that the femur with the prosthetic shaft is pivoted as far as possible in various directions, in that it is determined whether the central point of the bearing cup and the central point of the spherical joint surface move apart from one another during this process, and in that, for each pivoting direction, the maximum pivoting angle is thus determined, at which the central points begin to move apart from one another. A device for carrying out this method is also proposed.
