コンピュータ支援の人工股関節置換手術

Japanese Patent JP2006509609

A

A method performed on an anatomical bone model or on a cadaver for guiding an operator in altering a pelvis or a subsequent insertion of a pelvic implant in computer-assisted surgery, comprising the steps of creating a frame of reference related to geometry information of a pelvis, the frame of reference being trackable for position and orientation, obtaining a pelvic orientation relating to a given posture of the patient with respect to the frame of reference; and altering the acetabulum for a subsequent insertion of the pelvic implant in the acetabulum by presenting information about a current implant orientation with respect to said pelvic orientation, the current implant orientation being calculated as a function of a tracking of a surgical tool altering the acetabulum for receiving the pelvic implant, and of the frame of reference, positioning the patient in a given posture with respect to a plane of reference and digitizing the plane of reference with respect to a trackable reference such that orientation information associating the frame of reference to the given posture is calculable as a function of the orientation of the plane of reference.
