Purpose: Our aim was to assess the change of vertebral orientation, expressed in the sagittal plane, in the transversal plane and in the frontal plane, at each level from T1 to S1 between the supine position (like in in a CT scan) and the prone position lying on bolsters like in an OR.
Methods: Thirty-six patients were selected and included for a total number of one hundred and forty-eight vertebral levels. There were 30 females and 6 males.
Study Design: National cross-sectional study.
Objective: Thoracic kyphosis (TK) is related to sagittal parameters as pelvic tilt (PT), lumbar lordosis (LL) and pelvic incidence (PI). The equation TK = 2 (PT+LL-PI) was validated for adolescents.
Study Design: Retrospective cross-sectional study.
Objective: The aim was to describe existing global sagittal alignment parameters across ages and to analyze differences according to gender and pelvic incidence (PI).
Summary Of Background Data: Variability with age has been reported.
Study Design: Descriptive radiographic analysis of a prospective multi-center database.
Objective: This study aims to provide normative values of spinopelvic parameters and their correlations according to age and pelvic incidence (PI) of subjects without spinal deformity.
Methods: After Institutional Review Board (IRB) approval, 1540 full spine radiographs were analyzed.
Purpose: The aim was to describe radiographic cervical sagittal alignment variations according to age, gender and pelvic incidence (PI) and to investigate relationships with thoracic alignment.
Methods: A total of 2599 individuals (5-93 years) without spinal deformity were studied. Cranial cervical parameters were: McGregor slope, occipita-C2 angle, McGregor-C2 lordosis and C1-C2 lordosis.
Background: Odontoid fracture is the most common lesion of the cervical spine in persons age >70 years. Management of these fractures has become a public health issue. In this study, we evaluated bone fusion, early complications, and mortality in a cohort of patients age >75 years who underwent surgical management of odontoid fracture using the Harms technique.

Summary Of Background Data: No authors have highlighted correlation between the initial spinopelvic parameters and the postoperative outcome after a one-level TDR.
