Patent ID: 7699793

Claim:
A method for detecting an impingement of at least two joint components of a joint, comprising: detecting, via a medical tracking system, a spatial position of the at least two joint components during a relative movement of the at least two joint components; calculating, with computer assistance, an instantaneous center point of rotation or an instantaneous axis of rotation from the detected spatial positions of the at least two joint components; when a first joint component of the at least two joint components is moved relative to a second joint component of the at least two joint components, 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; concluding that there is an impingement of the at least two joint components when at least one of the calculated instantaneous center point of rotation or the calculated instantaneous axis of rotation deviates from the respective expectation range; and providing an output indicative of whether or not there is an impingement of the at least two joint components.
