Predicting the Effect of Bilateral Pelvic Osteotomy on Sagittal Alignment Correction and Surrounding Muscles: A Mathematical Model

<div>Schematic representation of the sagittal view of the spinopelvis system showing proposed bilateral pelvic osteotomy (BPO) procedure. Osteotomy will be performed caudal to SIJ but above the hip joints. A small change in pelvis opening angle (OA) will result in considerable sagittal vertical axis (SVA) correction.</div>
