A device for registering in a medical navigation system a position and/or orientation of a patient's pelvis includes a pelvic registration frame. A plurality of positioning elements are arranged on the pelvic registration frame so as to define a plane, wherein the plurality of positioning elements are movable with respect to each other to enable placement of the positioning elements at defined pelvic points of the patient's pelvis. At least one position transmitter is arranged in an unambiguously defined position and/or orientation relative to the frame.

Pelvic registration device for medical navigation

A planning method and device for knee implants, wherein spatial data on the configuration of a patient's genicular anatomy, in particular of at least a part of the femur and/or the patella and/or the tibia, are captured in order to be inputted into a computer-assisted planning station; the movement of the parts of the genicular anatomy is recorded using a tracking and/or motion capturing method; the captured anatomical and movement data are made available to the computer-assisted planning station; a part of the patient's genicular anatomy is virtually replaced in the planning station by a sample implant and movements of the knee together with the sample implant are simulated; contact and impingement between the non-replaced parts of the genicular anatomy and the implant during the virtual movement is ascertained according to its magnitude; and wherein an adjustment of the positioning, shape or orientation of the implant or of a number of these parameters is determined until the contact and impingement become non-critical and the adjustment thus determined is defined as a suitable adjustment.
