Method for selection of an femoral implant

摘要

For the selection of the ball implant in the thigh bone, for hip joint replacement, reference points (5) are established from anatomical landmarks at the thigh bone neck (1) and/or head (6) of the patient. A model is prepared from the three-dimensional spatial reference points. Implant models are positioned at the thigh model to establish which is the most suitable. A scanning unit (13) is linked to a navigation system (20) with at least one infra red camera (22).
