Can Pelvic Incidence Change After Lumbo-Pelvic Fixation for Adult Spine Deformity, and Would the Change be Affected by the Type of Pelvic Fixation?

Abstract: Study design. Retrospective review.Objective. To assess the change in pelvic incidence (PI) after lumbo-pelvic fixation and the differential impact of the type of pelvic fixation: S2-alar-iliac screws (S2AI) versus Iliac screws (IS) on postoperative PI. Summary of background data. Recent studies suggest that changes occur to the previously assumed fixed PI after spino-pelvic fixation. Methods. Adult spine deformity (ASD) patients who underwent spino-pelvic fixation with ≥ 4 levels of fusion were included. Preo… Show more

“…Rizkallah et al 1 studied in their article the change of pelvic incidence (PI) after lumbo-pelvic fixation and compared this change in two types of fixations. PI as defined by Duval-Beaupère is the angle between the line perpendicular to the sacral plate and the line connecting this the central of the sacral plate to the axis of the bi-femoral head 2 .…”
