Abstract
Hip joint navigation systems and methods are provided. In some embodiments, the systems and methods described herein determine a table reference plane that approximates the Anterior Pelvic Plane. In some embodiments, the systems and methods described herein measure a pre-operative and post-operative point. In some embodiments, the comparison of the pre-operative and post-operative point corresponds to changes in leg length and joint offset. In some embodiments, the systems and methods described herein determine an Adjusted Plane. In some embodiments, the Adjusted Plane adjusts for tilt by rotating the Anterior Pelvic Plane about the inter-ASIS line. In some embodiments, the Adjusted Plane improves correlation between navigated cup angles and post-operative images.
