BACKGROUND: Degenerative lumbar spinal stenosis (DLSS) is a common health problem in the elderly and usually associated with three-joint complex degeneration. Schmorl's nodes (SNs) are described as vertical herniation of the disc into the vertebral body through a weakened part of the end plate that can lead to disc degeneration. Since SNs can harm the spine unit stability, the association between DLSS and SNs is expected. The aim of this study is to shed light on the relationship between degenerative lumbar spinal stenosis and SNs...

BACKGROUND CONTEXT: Schwab classification for adult degenerative scoliosis (ADS) concluded that health-related quality of life (HRQOL) was closely related to curve type and three sagittal modifiers. It was suggested that pelvic incidence minus lumbar lordosis value (PI-LL) should be corrected within -10°~+10°. However, recent studies also indicated that ideal clinical outcomes could also be achieved in patients without ideal PI-LL mentioned above. PURPOSE: This study evaluated the relation between the clinical outcomes and the pelvic incidence minus lumbar lordosis value (PI-LL) of Chinese patients with ADS who received long posterior internal fixation and fusion...
