To investigate whether multi-shot diffusion-weighted imaging (ms-DWI) could be applied in diagnosis and quantitative evaluation of cervical spondylotic myelopathy (CSM). ⋯ The ms-DWI could be applied in diagnosis and quantitive assessment of CSM according to lADC and rADC. A new parameter, rADC, could be served as a diagnostic indice for CSM, which may quantitively reflect the severity of CSM. These slides can be retrieved under Electronic Supplementary Material.

Both increased sagittal vertical axis (SVA) and sarcopenia affect performance of daily activities and morbidity in the elderly; however, little is known regarding their relationship. The aim of this study was to analyze the association between sarcopenia and increased SVA. ⋯ Sarcopenia and fatty degeneration of paraspinal muscle are closely related to increased SVA in the elderly.

This is a retrospective, single-institution, cohort study. ⋯ Mersilene tape at UIV + 1 level decreases the risk of PJK following PIF for ASD. These slides can be retrieved under Electronic Supplementary Material.

Lateral interbody fusion and posterior percutaneous pedicle screw (LIF-PPS) fixation has been performed in two-stage positioning. The aim of this study was to investigate the surgical outcomes of simultaneous single-position LIF-PPS fixation using O-arm-based navigation. ⋯ Single-position surgery exhibited comparable clinical outcomes and local lordosis acquisition with conventional repositioning LIF-PPS fixation. This single-position minimally invasive technique reduces the occupancy time of the operating room and workforce requirements. These slides can be retrieved under Electronic Supplementary Material.

To compare the acute behaviors of pelvic incidence (PI) between elderly adult spinal deformity (ASD) patients with severe and minor sagittal deformity based on SRS-Schwab classification and to identify the mechanism of the variability in PI after long fusion to S1. ⋯ PI spontaneously increases in elderly ASD patients with severe sagittal deformity after long fusion to sacrum, while is relative invariable in those with minor sagittal deformity. Variation in PI could be considered as a secondary change compensating for the spinal sagittal malalignment under long spinal fusion in elderly patients.
