Patent ID: 8469902

Claim:
A method for determining an orientation of an artificial joint in a human or animal body, wherein a first part of the artificial joint and a second part of the artificial joint are designed to form an artificial joint connection with each other, the first part provided for implantation in a first body structure of the human or animal body, and the second part provided for implantation in a second body structure of the human or animal body, the first and second parts replacing an anatomical joint that connects or connected the first body structure to the second body structure ( 500 ), comprising: before replacement of the anatomical joint, obtaining body structure data that describe a mobility of the first body structure relative to the second body structure, the first body structure and the second body structure being connected by the anatomical joint and the mobility including information concerning at least one of a plurality of possible relative movements of the first body structure relative to the second body structure or a plurality of possible relative locations of the first body structure relative to the second body structure; and based on the body structure data, determining, with computer assistance, an orientation of the first and second part of the artificial joint for planning an orientation of the artificial joint that is suitable for implantation.
