Multicenter Study
Imaging Characteristics of Non-Rheumatoid Arthritis Patients With Retro-Odontoid Pseudotumor: A Multicenter Case-Control Study.
Multicenter case-control study. ⋯ The development of ROP was associated with degeneration of facet joints and intervertebral disks in the middle and lower cervical spine. Our findings suggest that decreased mobility of the middle and lower cervical spine may cause instability in the upper cervical spine, leading to the formation of ROP.

Comparative Study
Comparison of Bone Mineral Density in Children and Adolescents on CT Versus DEXA Scan.
Retrospective cross-sectional. ⋯ HU on lumbar CT in children and adolescents with DEXA Z -scores <-2.0, were lower when compared with healthy matched controls. This study suggests that HU on opportunistic CT scans of the spine may be used as a reasonable proxy for BMD in the pediatric population.

Comparative Study Observational Study
Comparison of Patients Operated for Lumbar Spinal Stenosis with and without Spondylolisthesis - A Secondary Analysis of the NORDSTEN Trials.
Observational cohort study (secondary analysis of two randomized trials). ⋯ II.

Retrospective cohort study. ⋯ L1PA may be a helpful radiographic consideration that translates to clinically relevant outcomes in spinal deformity. However, it does not appear as predictive of patient outcomes after single-level fusion for patients with L4-L5 degenerative spondylolisthesis. Further studies are warranted to investigate the role of L1PA in degenerative spine patients.

This study was aimed to investigate the potential roles of circTMTC1 in the underlying pathophysiological mechanisms of ossification of the ligamentum flavum (OLF). ⋯ Our findings suggested the circTMTC1-DDX3X-NLRP3 inflammasome signaling plays a pivotal role in osteogenic differentiation of human ligamentum flavum cells, which may provide novel diagnostic and therapeutic strategies for OLF.
