Pelvic Incidence Animation

Video Description

This video animation demonstrates a low, medium, and high pelvic incidence.

It shows the mathematical relationship between pelvic incidence, sacral slope, and pelvic tilt.

Pelvic incidence = pelvic tilt + sacral slope

Hanson et al performed a retrospective radiographic analysis of 40 patients and found pelvic incidence was significantly higher in patients with low- and high-grade isthmic spondylolisthesis as compared with controls and had significant correlation with the Meyerding-Newman grades (P = 0.03).Hanson DS, Bridwell KH, Rhee JM, Lenke LG.
