A cross-sectional study of 96 patients with lumbosacral adolescent spondylolisthesis. ⋯ LSK is significantly correlated to the physical aspect of the quality of life of adolescents with spondylolisthesis. The implication of abnormal LSK is particularly evident in patients with high-grade spondylolisthesis. All evaluated LSK parameters seem equivalent to measure this effect. LSK should be routinely measured in adolescents with spondylolisthesis to fully appreciate the severity of the deformity and its clinical association with the quality of life of the patient.

Retrospective observational study utilizing prospectively collected population-based data. ⋯ The incidence of TSCI in our population has remained remarkably stable, and age-related changes mirror those in the population across 10 years. An increased tendency to surgical treatment during the 10 years of this study has not resulted in concomitant changes in patients' in-hospital mortality or length of stay.

In vitro cadaveric study of thoracic spinal cord intramedullary pressure (IMP) in kyphotic deformity. ⋯ Thoracic kyphosis less than +51° resulted in no meaningful increase in IMP, whereas kyphosis measuring +51° to +63° resulted in minor increases in IMP. After the thoracic kyphosis exceeded +63°, IMP increased significantly. ΔIMP with spinal alignment may help explain the wide range of "normal" thoracic neutral upright sagittal alignment in studies of asymptomatic adult individuals and may help further define thoracic kyphotic deformity.

A retrospective cohort study. ⋯ Our retrospective evaluation indicates that there should be a lower threshold for obtaining arterial imaging with cervical injury patterns historically known to compromise the vasculature, which also have concomitant displaced cervical spine injuries and/or a neurological deficit.

Comparative Study
Supine thoracolumbar sagittal spine alignment: comparing computerized tomography and plain radiographs.
Imaging supine sagittal alignment study. ⋯ The results from this study provide a supine reference for sagittal spine alignment using the Cobb method for both CT scans and plain radiographs. It also demonstrates the high degree of reliability between measurements from 2 imaging sources and various observers as shown with the ICC values.
