Abstract

A device and method for detecting an impingement of joint components of a joint includes detecting a spatial position of each joint component during a relative movement of the joint components; calculating an instantaneous center point of rotation or an instantaneous axis of rotation from the detected spatial positions of the joint components; when one joint component moves relative to the other joint component, establishing whether the calculated instantaneous center point of rotation moves within a first expectation range or whether the calculated instantaneous axis of rotation moves within a second expectation range; and establishing that there is an impingement of the joint components when at least one of the calculated instantaneous center point of rotation or the calculated instantaneous axis of rotation leaves or exits the respective expectation range.
