Lumbar spinal stenosis (LSS) is commonly assessed on MRI by measuring dural sac cross-sectional area (DSCA). A new method, morphological grading A-D, has recently been introduced as an alternative method. ⋯ The study shows that the inter- and intraobserver agreements of DSCA and morphological grading A-D were acceptable and their intercorrelation is strong. Both methods may be used in the MRI evaluation of LSS.

The adolescent idiopathic scoliosis (AIS) pathogenesis remains unknown. Certain studies have shown that there is a correlation between manual laterality and scoliotic deviation. A full study of manual laterality needs to be paired with one for visual dominance. With the aim of physiopathological research, we have evaluated the manual and visual laterality in AIS. ⋯ Those with right thoracic AIS show a higher occurrence of crossed eye-hand laterality. This could point physiopathological research of AIS towards functional abnormality of the optic chiasma through underuse of cross visual pathways, and in particular accessory optic pathways. It would be useful to explore this by carrying out research on AISs through neuroimaging and neurofunctional exploration.

The purpose of this study was to examine radiographic and clinical outcomes in the treatment of adult degenerative scoliosis using a minimally invasive (MI) lateral approach for anterior lumbar interbody fusion (IBF). ⋯ MI lateral IBF in the treatment of degenerative scoliosis results in lower complication rates and clinical and radiographic outcomes equivalent to reports in the literature of conventional approaches.

Congenital progressive kyphoscoliosis associated with split spinal cord malformation (SSCM) is a very rare disease. ⋯ Based on the Grand Round case and relevant literature, we discuss the different options for the treatment of congenital kyphoscoliosis associated with type I SSCM. In the patient whose kyphoscoliosis is severe and rigid, we recommend an initial release followed by halo-wheelchair traction gradually to correct the deformity, once optimal correction acquires during the traction, the posterior instrumented fusion with VCR upper the bony spur could be done safely without the resection of bony spur.

The effect of diffuse idiopathic skeletal hyperostosis (DISH) on spinopelvic alignment in patients with lumbar spinal stenosis (LSS) remains unclear. The aim of this study was to investigate the association between DISH and sagittal spinopelvic alignment in patients undergoing surgery for LSS. ⋯ The prevalence of DISH in patients with LSS was relatively high. Spinopelvic alignment is affected by the presence of DISH, especially in patients with lower fused vertebral ends at the lumbar lesion. These results may offer an explanation for the frequent kyphotic changes in the spine of elderly patients.
