Correction of the Lumbosacral Fractional Curve vs. Thoracolumbar Major Curves in Adult Spinal Deformity Surgery: How Much Do We Correct Each Curve?
OBJECTIVE In adult spinal deformity (ASD) surgery, lumbosacral fractional curve (LSF) is stiffer and harder to correct than thoracolumbar major curve (MC). In patients undergoing ASD surgery, we aimed to:1) assess correction rate of LSF vs. MC, 2) determine association between their correction and postoperative alignme...
