Pelvic Flexion Measurement From Lateral Projection Radiographs is Clinically Reliable

摘要

BackgroundPelvic flexion affects orientation of the acetabular cup; however, pelvic position is not static in daily activities. During THA it is difficult to know the degree of pelvic flexion with the patient in the lateral position and that position is static. However, surgeons need to appropriately determine pelvic tilt to properly insert the acetabular component.
