Abstract
Planning for total hip arthroplasty (THA) has traditionally been performed using static
supine anteroposterior radiographs of the pelvis. Recent advances in imaging technology
and the understanding of human spinopelvic kinematics have made weight-bearing radiography
an important adjunct to supine imaging. Hip surgeons can use weight-bearing imaging
to optimize THA component position to prevent hip instability and early component
wear. The goal of this narrative review is to delineate the fundamentals of spinopelvic
kinematics, the benefits of surgical planning using weight-bearing radiography, and
the underpinnings of upright full-body stereoradiography as a useful adjunct to traditional
supine radiographs.
