Claim 0:
1. A method for detecting stability of a medical implant, the method comprising:
applying a force to the medical implant with a probe;
based on the applied force, measuring a vibration of the medical implant via a vibration sensor;
comparing the measured vibration of the medical implant based on the applied force with a natural frequency value or a linear stiffness coefficient predicted by a computer model of the medical implant; and
based on the comparison, determining an angular stiffness coefficient of the medical implant, wherein the angular stiffness coefficient corresponds to a stiffness of a rotation about an axis perpendicular to a centerline of the medical implant, and wherein the angular stiffness coefficient indicates a stability of the medical implant.
