Comparison of the Sagittal Age-Adjusted Score and the T4-L1PA mismatch in Discriminating Proximal Junctional Kyphosis and Failure in Adult Spinal Deformity Surgery.
STUDY DESIGN Retrospective single-center study. OBJECTIVE To compare the discriminative ability of the sagittal age-adjusted score (SAAS) and the T4-L1PA mismatch for proximal junctional kyphosis (PJK) and proximal junctional failure (PJF) after adult spinal deformity (ASD) surgery. SUMMARY OF BACKGROUND DATA The S...
