Use of pelvic incidence on preoperative prone and supine radiography to predict postoperative pelvic incidence following thoracolumbar fusion for adult spinal deformity
There are position-dependent changes in PI among patients without prior pelvic fixation. Statistically significant changes in PI are seen even after pelvic fixation with a single S2-alar-iliac screw bilaterally. Postoperative PI was best predicted by preoperative PI on supine and prone radiographs rather than upright radiographs, suggesting that preoperative prone and supine radiographs may provide surgeons with the best information for achieving PI-lumbar lordosis mismatch < 10°.
