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

Figure 2

Diagram of the sagittal view of the spinopelvic system showing landmark points used to measure angles and distances used in the predictive equations (a). The location of these points was identified and measured in an actual full sagittal spine X-ray (b).
