To determine the effects of thoracic stiffness on mechanical stress in the lumbar spine during motion. ⋯ Biomechanically, disc stress and pars interarticularis stress decrease in the flexible thoracic spine. Flexibility of the thoracic spine reduces lumbar spine loading and could help to prevent stress-related disorders.

This study examined cervical center of rotation (COR) positions in 7 postures using validated cone beam computed tomography (CBCT) combined with 3D-3D registration in healthy volunteers. ⋯ Our findings reveal segment-specific and posture-dependent COR variations. Notably, the CORs of C3/4, C4/5, and C5/6 consistently align near the intervertebral disc's GC at different postures, supporting their suitability for total disc replacement surgery within the C3/4 to C5/6 segments.

We sought to identify trends in the number of female neurosurgeons across each state and identify state characteristics that affect such values. ⋯ States with more training programs, female physicians, and paid parental leave policies saw a large number of female neurosurgeons. Diversity in the general population is also crucial to improving the equity in gender representation of neurosurgeons in each state. The increase in female neurosurgery representation in rural states shows that the shortage of neurosurgeons in underserved areas is creating a unique niche for female neurosurgeons to excel.

To describe an intuitive and useful method for measuring the global impact of a medical scholar's research ideas by examining cross-border citations (CBCs) of peer-reviewed neurosurgical publications. ⋯ This intuitive update to the h-index uses CBCs to measure the global impact of scientific research. The hglobal-index may provide insight into global diffusion of medical ideas, which can be used for social science research, author self-assessment, and academic promotion.

Vascular neurosurgical procedures require temporary or permanent surgical clips to treat cerebral aneurysms, arteriovenous malformations, or bypass surgery. In this scenario, surgical clips should have specific characteristics such as high-quality material, proper design, closing force, and biocompatibility. Due to these characteristics, the price of these clips does not allow their availability at the experimental surgery laboratory worldwide. ⋯ Making practical low-cost clips for use in laboratory procedures or during low-flow anastomosis as temporary clips is possible. The main advantages are the low cost and the worldwide availability of the basic materials. The main disadvantage is the learning curve to get the ability to master the manufacturing of these clips.
