Prospective clinical and radiological analysis of children with complex cervical deformities for the safety of cervical pedicle screw insertion. ⋯ Safe insertion of cervical pedicle screws is possible in children. Iso-C navigation provides real-time virtual imaging and improves the safety and accuracy of successful pedicle fixation even in altered vertebral anatomy. Pedicle width morphometrics do not restrict screw insertion.

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.

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.

A cross-sectional study. ⋯ Positive personality characteristics could play a crucial role in patient adjustment, and thus clinicians should take into account the positive path to capacity to better understand the chronic pain experience.

An in vitro study using ovine intervertebral discs to correlate the effects of increasing advanced glycation end-products (AGEs) with disc hydration evaluated by magnetic resonance imaging (MRI). ⋯ This study demonstrates that levels of AGEs in the IVD may affect the tissue water content. Moreover, these ribosylation-mediated changes in tissue hydration were detectable using T2 relaxation MRI. T2 relaxation MRI may provide a noninvasive tool to measure in vivo changes in disc hydration that are negatively correlated with the accumulation of AGEs.
