Abstract: A method for performing a surgical procedure related to a pelvis of a patient comprises adjusting a length between ends of a digitizer device to a distance between opposite landmarks of the pelvis of the patient. The ends of the digitizer device are applied against the opposite landmarks of the pelvis. An inertial sensor unit of the digitizer device is initialized to set an orientation of the digitizer device relative to a medio-lateral axis of the patient, the medio-lateral axis of the patient being part of a pelvic coordinate system. A tool is navigated within the pelvic coordinate system during a surgical procedure.

Abstract: A pelvic digitizer device has a body defined by a shaft having a tooling end and a handle end with a handle for being manipulated. A visual guide is oriented in a reference plane of the digitizer device. A cup is connected to the tooling end and adapted to be received in an acetabulum of a patient. An inertial sensor unit is connected to the body, the inertial sensor unit having a preset orientation aligned with the reference plane.
