Pelvic compensation, as quantified by the pelvic tilt (PT), has been identified as a crucial compensatory mechanism in patients with adult spinal deformity (ASD). However, it remains uncertain whether PT has important roles in predicting the occurrence of proximal junctional kyphosis (PJK). Therefor...
