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.

Abstract: A computer-assisted surgery system for outputting at least one of a leg length discrepancy and an offset between a preoperative leg condition and a post-implant rejointing leg condition comprises instruments. An inertial sensor unit is connected to one of the instrument, the inertial sensor unit producing readings representative of its orientation. A computer-assisted surgery processor unit operating a surgical assistance procedure and comprises a coordinate system module for setting a pelvic coordinate system from readings of the at least one inertial sensor unit when the at least one instrument is in a given orientation relative to the pelvis, a tracking module for tracking an orientation of the at least one instrument relative to the pelvic coordinate system during movements thereof using the readings from the inertial sensor unit on the instrument, and a geometrical relation data module for recording preoperatively a medio-lateral orientation of the at least one instrument representative of a medio-lateral axis of the legs relative to the pelvic coordinate system and a distance between the legs along the medio-lateral axis, for recording after implant rejointing the medio-lateral orientation and said distance, and for calculating at least one of a leg length discrepancy and an offset, based on said distances and said medio-lateral orientations. An interface outputs at least the leg length discrepancy or the offset between the preoperative leg condition and the post-implant rejointing leg condition.

Abstract: A method for assisting in positioning the acetabular cup comprises orienting a cup positioning instrument with a cup thereon in an initial reference orientation relative to an acetabulum of a pelvis with the cup forming a joint with the acetabulum, the cup positioning instrument comprising an inertial sensor unit with pre-planned orientation data for a desired cup orientation based on at least one landmark of the pelvis, The cup positioning instrument is rotated to a desired abduction angle as guided by an interface of the cup positioning instrument, based on movements relative to at least one landmark. The cup positioning instrument is rotated to a desired anteversion angle as guided by the interface of the cup positioning instrument, based on movements relative to the at least one landmark. Upon reaching the desired cup orientation as indicated by the interface, the cup is impacted into the acetabulum.
