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.

Abstract: Systems and methods for determining position and orientation of a bone of an anatomical feature are described. These include the use of a wearable holder configured to be mounted about an outer-skin surface of the anatomical feature, such that the anatomical feature and the bone are positioned in fixed relation with respect to the wearable holder when the wearable holder is mounted about the anatomical feature. Reference marker arrays are fixedly mounted to the wearable holder, each being positioned on the wearable holder to identify a landmark of the bone within the wearable holder when the wearable holder is mounted to the anatomical feature. The position and orientation of the reference markers are trackable to determine position and orientation of the wearable holder in a reference coordinate system, thereby enabling position and orientation of the landmarks on the bone to be determined.

Abstract: A computer-assisted surgery (CAS) system outputs a leg length discrepancy and/or an offset between conditions. An inertial sensor unit is connected to an instrument(s) to produce readings representative of its orientation. A CAS processor unit has a coordinate system module for setting a pelvic coordinate system from readings of the inertial sensor unit, a tracking module for tracking an orientation of the instrument(s) relative to the pelvic coordinate system during movements thereof, and a geometrical relation data module for recording preoperatively a medio-lateral orientation of the instrument(s) representative of a medio-lateral axis of the legs and a distance between the legs, for recording after implant rejointing the medio-lateral orientation and the distance, and for calculating a leg length discrepancy and/or an offset, based on the distances and the medio-lateral orientations. An interface outputs the leg length discrepancy and/or the offset between leg conditions.
