Background: The restoration of normal sagittal alignment is a critical goal in adult spinal
deformity surgery to achieve favorable outcomes and prevent mechanical complications …

Background The Global Alignment and Proportion (GAP) score, based on pelvic incidence-
based proportional parameters, was recently developed to predict mechanical complications …

Abstract Study Design Retrospective analysis of prospectively collected data. Objectives To
validate the Global Alignment and Proportion (GAP) score in a single-center cohort of adult …

Background context Surgery for adult spinal deformity is a challenging and complex
procedure with high reported complication (8.4%–42%) and revision rates (9%–17.6%) …

Sagittal spinal misalignment (SSM) is an established cause of pain and disability. Treating
physicians must be familiar with the radiographic findings consistent with SSM. Additionally …

Study Design. Retrospective review of prospective, multicenter database. Objective. The aim
of the study was to determine age-specific spino-pelvic parameters, to extrapolate age …

Object Sagittal spinopelvic imbalance is a major contributor to pain and disability for patients
with adult spinal deformity (ASD). Preoperative planning is essential for pedicle subtraction …
