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

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

Purpose We aim at analysing the impact of anterior lumbar interbody fusion (ALIF) in
restoring the main spinopelvic parameters, along with its potentials and limitations in …

Adequate sagittal balance (SB) is essential to maintain an upright, efficient, and painless
posture. It has been shown that sagittal profile alterations affect quality of life of patients with …

Purpose To investigate the age-based normal values of sagittal parameters and establish
the relationships between them in Chinese population. Method Two hundred eighteen …

Background: Our understanding of the relationship between sagittal alignment and
mechanical complications is evolving. In normal spines, the L1-pelvic angle (L1PA) …

Purpose. Despite adequate correction, the pelvis may fail to readjust, deemed pelvic
nonresponse (PNR). To assess alignment outcomes [PNR, proximal junctional kyphosis …

Purpose The aim of our study is to analyse mid-to long-term severe adult spinal deformity
(ASD) surgery outcomes by comparing three-column osteotomies (3CO) and multiple …

Pelvic motion acting as a hinge between the spine and hips is essential to maintain proper
balance during bipedalism. Pelvic rotation is recruited as a compensation mechanism when …

Study Design. Retrospective cohort study. Objective. Assess whether modifying spinal
alignment goals to accommodate frailty considerations will decrease mechanical …
