Pelvic Position at Cup Placement Compared With Intraoperative Pelvic Motion in the Lateral Decubitus Position.

ABSTRACT:

Background

It is important for surgeons to consider the pelvic position at cup placement for accurate cup placement. This position depends on both the pelvic position at set-up and the degree of intraoperative pelvic motion from set-up to cup placement. The present study aimed to characterize and compare the pelvic position at cup placement with intraoperative pelvic motion during primary total hip arthroplasty in the lateral decubitus position. This study also investigated whether the pelvic position at set-up or intraoperative pelvic motion had a greater impact on the pelvic position at cup placement.

Methods

Pelvic positions were measured in 86 hips using an augmented reality-based portable hip navigation system. The pelvic reference plane was registered in the supine pos
