Purpose The aims of this study were to explore the correlations between thoracic kyphosis
(TK) and lumbar lordosis (LL) parameters and to build corresponding linear regressions to …

Purpose Thoracic kyphosis (TK) remained in the shadow of lumbar lordosis. Based on
Berthonnaud and Roussouly segmentation, TK is divided into two arches: upper TK (UTK) …

Purpose Distal thoracic kyphosis (DTK) equivalent to proximal lumbar lordosis (PLL) is the
sum of pelvic tilt (PT) and the difference (Δ) between lumbar lordosis (LL) and pelvic …

Purpose Previous studies only investigated the simple linear relationships of global tilt (GT)
with thoracic kyphosis (TK), lumbar lordosis (LL) and pelvic incidence (PI). This study aimed …

Study Design Prospective cohort study. Objectives To show population variance in the
Inflection Point (IP) and its role in defining maximum Thoracic Kyphosis (TK) and Lumbar …

BACKGROUND CONTEXT The usual definition of thoracic kyphosis (TK) is the angle
between T4 and T12. However, little is known about the overall shape of the TK in adults …

Study Design. Prospective, cross-sectional cohort study. Objective. To determine the
relationship between lumbar shape and sagittal parameters. Summary of Background Data …

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 …

Background The precise prediction of ideal lumbar lordosis (LL) has become increasingly
important in clinical practice. The aim of this study was to explore the regulatory mechanisms …

Study Design. A retrospective cohort study of consecutive patients. Objective. To investigate
the clinical value of thoracic tilt (TT) in characterizing thoracic compensation and predicting …
