Abstract

See full text

An acetabular component alignment device for total hip arthroplasty comprises a calibration component allowing for aligning a main instrument axis (5) of the acetabular component depending on a set of two patient specific calibration parameters relating to rotational offsets of the acetabular component, whereas the device is constructed in such a way that calibration parameters may be chosen such that a second parameter of the set of calibration parameters is adjustable independently from a first parameter of the set of calibration parameters by rotating the acetabular component around the main instrument axis (5) of the acetabular component. A method for obtaining patient specific calibration parameters for alignment of an acetabular component in total hip arthroplasty, comprises the steps of determining patient specific morphology information relating to a geometry of the patient's pelvis; and processing the patient specific morphology information for obtaining a set of two patient specific calibration parameters relating to rotational offsets of the acetabular component. The calibration parameters are chosen such that a second parameter of the set of calibration parameters may be adjusted independently from a first parameter of the set of calibration parameters by rotating the acetabular component around a main instrument axis of the acetabular component.
