This study aims to evaluate the safety and efficacy of the ultrasonic bone burr (UBB) in facilitating C1 pedicle screw placement for atlantoaxial instability (AAI) treatment, compared to the conventional high-speed drill (HSD) technique. ⋯ UBB is a viable alternative for C1 pedicle screw placement, associated with reduced blood loss and shorter operation time, while achieving comparable clinical outcomes to the conventional HSD method. Nevertheless, further research with a larger sample size is needed.

Delayed symptomatic hyponatremia (DSH) is one of the common complications following endoscopic endonasal surgery (EES). Currently, published studies have predominantly focused on delayed postoperative hyponatremia, while there is relatively limited research on DSH. ⋯ The incidence rate of DSH after EES in patients was 16.8%. Knosp grade ≥3, intraoperative cerebrospinal fluid leaks, serum sodium concentration on the second day after surgery, and postoperative diabetes insipidus were associated with the occurrence of DSH.

Polyetheretherketone (PEEK) cages and structural allografts (SAs) are commonly used in Anterior Cervical Discectomy and Fusion (ACDF), yet their postoperative results remain uncertain. This meta-analysis was conducted to determine whether there were any differences in outcomes between patients who received these two grafts in ACDF. ⋯ SA demonstrates better fusion and lower subsidence rates than the PEEK cage in ACDF. Nevertheless, these two cages resulted in equally successful postoperative clinical performances.

There are critical disparities in the neurosurgical care provided around the globe due to challenges in resource allocation, training, and infrastructure. Global neurosurgical collaborations have replaced classical mission trips to address these disparities. However, the development of these collaborations and the impact of research funding on their growth has not yet been systematically studied. In this article, we use a graph theoretical approach to investigate trends in funding and co-authorship between and among authors from high-income countries (HICs) and authors from low- and middle-income countries (LMICs). ⋯ This work shows significant and rapid growth in international neurosurgical partnerships, especially in HIC-LMIC and LMIC-LMIC collaborations. Also, a significant positive relationship exists between research funding and LMIC-HIC co-authorship trends. This work encourages us as a community to continue to expand our translational collaborations with LMIC neurosurgeons and establish funding mechanisms independent of HIC authors.

In poor-grade aneurysm subarachnoid hemorrhage (PaSAH), the use of external ventricular drainage (EVD) may be closely related to the occurrence of shunt-dependent hydrocephalus (SDHC). The purpose of this study was to investigate the effect of EVD on SDHC and prognosis after microsurgical clipping patients with PaSAH. ⋯ EVD implantation is an independent risk factor for SDHC after PaSAH, and a large drainage volume in the first 3 days after EVD implantation is an independent risk factor for SDHC after PaSAH. The drainage volume on the first day after surgery is the best predictor of SDHC after PaSAH. SDHC after PaSAH is the strongest independent risk factor for poor prognosis and prolongs hospital stay.
