Purpose Of The Study: The anterior pelvic plane, also called the Lewinnek plane, is commonly used as the reference plane to guide imageless computer assisted surgery for total hip arthroplasty (THA) because this plane is considered to be globally vertical in the standing position. To our knowledge, no study has evaluated this hypothesis or the potential variations in orientation as a function of gender, position of the subject, or THA insertion. The purpose of this work was to examine these different hypotheses in a radio-clinical study. Read More

Objective: The purpose of this study was to investigate the relationship of cup position versus pelvic lateral tilt and inclination. While computer assisted navigation systems use only the pelvic frontal plane for cup placement, it is important to realize the effect of leg length differences or increased pelvic inclination, i.e. Read More

The morpho-metrical features of the human pelvis differ according to gender, particularly with regard to size and shape, and bipedal standing posture appears to have been a major determinant of pelvic structure. In standing posture, the three points of the right and left superior anterior iliac spines and pubic tubercle are in contact with the vertical frontal plane. In this situation, the superior anterior iliac spine is lower than the superior posterior iliac spine. Read More

The purpose of the current study was to evaluate whether safe acetabular component position depends on differences in pelvic location between the supine, standing, and sitting positions. The subjects of the current study were 101 patients who had total hip arthroplasty. Anteroposterior radiographs of the pelvis with the patients in the supine, standing, and sitting positions were obtained preoperatively and 1 year after total hip arthroplasty. Read More
