Adult spinal deformity (ASD) surgery aims to correct abnormal spinal curvature in adults,
leading to improved functionality and reduced pain. However, this surgery is associated with …

OBJECTIVE The objective of this study was to explore the rate of proximal junctional failure
(PJF) and functional outcomes of normative alignment goals compared with alignment …

OBJECTIVE The objective was to evaluate factors associated with the long-term durability of
outcomes in adult spinal deformity (ASD) patients. METHODS Operative ASD patients fused …

Study Design. Retrospective study. Objectives. To investigate the incidence and risk factors
of mechanical failure (MF) following anterior column realignment (ACR) in patients with …

Purpose While existing adult spinal deformity (ASD) alignment schemas acknowledge the
dynamic relationship between the pelvis and spine, consideration of vertebral pelvic angles …

Study design Retrospective review of a prospectively-collected multicenter database.
Objectives The objective of this study was to determine optimal strategies in terms of focal …

Background Despite numerous studies identifying risk factors for proximal junctional failure
(PJF), risk factors for recurrent PJF (R-PJF) are still not well established. Therefore, we …

Background We sought to determine which aspect of the upper instrumented vertebrae (UIV)—
tilt angle or screw angle—was more strongly associated with:(1) proximal junctional …

Background The anterior-to-psoas (ATP) approach to the lumbar spine has been proposed
as an alternative to the transpsoas approach for approaching the disc space without …

Aims: The aim of the study was to assess preoperative radiographic parameters predictive of
cervical deformity (CD) autocorrection in patients undergoing thoracolumbar deformity …
