Abstract

Purpose: In total hip arthroplasty, the accuracy of the cup inclination and version is influenced by the intraoperative pelvic movement. We modified the use of a hip navigation system to measure the pelvic movement in three directions at five steps during surgery. Methods: Forty-seven hips were operated on by the direct anterior approach in a supine position. We monitored the pelvic position at setup, after femoral head resection, at acetabular exposure, after acetabular reaming, after cup implantation, and after maximum limb traction for reduction. Results: The pelvis tended to move toward the direction of abduction in the frontal plane during surgery (2.1 ± 1.5 degrees after cup implantation). The pelvis tended to move toward the direction of internal rotation by anterior retractor (1.7 ± 2.3 degrees at acetabular exposure) and toward the direction of anterior tilt by caudal retractor at obturator foramen (2.4 ± 1.7 degrees after cup implantation). Conclusion: Even in a supine position, the pelvis tended to move toward the direction of abduction by limb traction and toward the direction of internal rotation and anterior tilt by retractors. We must pay attention to the pelvic movement when fixing the cup even in a supine position.
