The effect of upper instrumented vertebra level on cervical sagittal alignment in Lenke 1 adolescent idiopathic scoliosis.
This study aimed to evaluate the relationship between upper instrumented vertebra (UIV) level and cervical sagittal alignment (CSA) in Lenke 1 adolescent idiopathic scoliosis (AIS) patients, treated with posterior instrumentation. The hypothesis was that higher level of UIV would cause decreased cervical lordosis. ⋯ IV.

Influence of posture on relationships between pelvic parameters and lumbar lordosis: Comparison of the standing, seated, and supine positions. A preliminary study.
Pelvic incidence (PI) is an anatomical parameter that is considered invariable in a given individual. Although changes in posture influence the mobile lumbar spine, lumbar lordosis (LL) and the pelvis are typically evaluated only in the standing position. Thus, whether other positions commonly used during daily activities influence the relationship between LL and PI is unknown. The objective of this study was to determine whether LL and sacral slope (SS) correlated with PI, using two standardised positions, seated and supine, different from the standing position that is generally used. ⋯ IV.
