Does age-adjusted pelvic incidence minus lumbar lordosis overcorrection truly increase the risk of proximal junctional failure? A confounder-adjusted multivariate analysis in adult spinal deformity.

BACKGROUND CONTEXT: Correction beyond age-adjusted pelvic incidence minus lumbar lordosis (PI-LL) targets (age-adjusted PI-LL overcorrection) is believed to increase the risk of proximal junctional failure (PJF) in adult spinal deformity (ASD) surger…
