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

»: 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.
