-
Retrospective study of a multicentric prospective database. ⋯ This study highlights the importance of vertebral contribution to lumbar lordosis, ranging from 8 to 21% among PI groups. Lumbar lordosis decreased with aging through decreased disc lordosis in the lower lumbar spine and increased body kyphosis in the upper lumbar spine. These results may help surgeons in the assessment of sagittal alignment and the selection of operative technique to achieve surgical correction.

Retrospective, observational study. ⋯ The mNGS test exhibits rapidity, efficiency, and accuracy, rendering it of immense diagnostic and therapeutic value in the realm of spinal infection diseases.
-
Retrospective study. ⋯ Understanding the difference in risk factors between B-PJF and L-PJF will facilitate the optimization of surgical outcome for patients with ASD. Appropriate correction of sagittal malalignment along with use of TP hook is advisable to mitigate both B-PJF and L-PJF development.

Retrospective cohort study. ⋯ IV.
-
This was a single-center prospective clinical and radiographic analysis of pedicle screw instrumentation with Robotic-assisted navigation (RAN) and augmented reality (AR). ⋯ RAN and AR both achieved high accuracy in lumbosacral pedicle screw placement, proving reliable for this procedure. However, RAN resulted in significantly more Grade-A screw placements than AR.
