ADJUSTABLE ENDOPROSTHESIS

摘要

The present invention relates to an endoprosthesis, comprising: - a first member (2) which is connected to a patient's bone; - a second member (3) which is adjustably coupled to the first member (2) by means of a coupling device (4); wherein the coupling device (4) is configured to generate a movement of the second member (3) relative to the first member (2). The present invention also relates to an artificial joint comprising such an endoprosthesis (1) and to an endoprosthesis placement system comprising such an endoprosthesis (1 ) or artificial joint and a projection device (7) which is configured to project visible light markings (8), acquired from pre-operational and/or intra-operational patient data, onto the patient and/or the endoprosthesis (1), thus enabling visible alignment markings (6) of the endoprosthesis (1) to be aligned with respect to projected visible light markings (8) so as to allow a proper adjustment of the endoprosthesis (1). The present invention also relates to a method of adjusting such an endoprosthesis (1) or artificial joint and to a computer program for performing such a method.
