The Use of Technology to Achieve the Functional Acetabular Safe Zone in Total Hip Arthroplasty.

Overview

»: Functional acetabular safe zones based on patient-specific factors during total hip arthroplasty are theorized to result in more optimal component stability than the use of traditional safe zones based on static targets. »: Preoperative planning that takes into account functional pelvic positions and spinopelvic mobility is increasingly recommended. »: Computer navigation and robotics can be utilized to help accurately achieve the targeted cup position within the functional safe zone. »: Each technology platform (imageless and image-based computer navigation and robotics) utilizes a specific referencing method for the pelvis, which influences anteversion and inclination values. »: The purpose of this article is to summarize how these different systems reconcile differences in pelvic referencing to ensure that the surgeon achieves the targeted functional cup position.
