Spinal fusion surgery is known to be an expensive intervention. Although innovative technologies in the field aim at improving operative efficiency and outcomes, total costs must be considered. The authors hope to elucidate any differences between robot-assisted (RA) and computed tomography navigation (CT-nav) or freehand fluoroscopy-guided (FFG) pedicle screw placement in relation to patient outcomes and cost-effectiveness in lumbar fusion surgery (LFS). ⋯ This study shows that RA pedicle screw placement in LFS provides similar patient outcomes to CT-nav and FFG. Robot-assisted operations were found to give rise to cost savings via decreased length of stay when compared to both CT-nav and FFG techniques. Cost-savings of $4086-$4865/patient and $7317-$9654/patient could be achieved when utilizing RA over CT-nav and FFG, respectively. However, extra upfront and maintenance costs may impact full adoption of RA in LFS.

Chiari malformations, characterized by the herniation of cerebellar tonsils through the foramen magnum, are complex neurosurgical conditions that pose significant diagnostic and therapeutic challenges.1 Traditional interventions, such as foramen magnum decompression, have been the mainstay of treatment but are not universally effective, especially in cases with underlying atlantoaxial instability. However, recent studies highlight the importance of atlantoaxial instability in their pathogenesis, shifting the therapeutic focus towards atlantoaxial fixation.2 Research shows that atlantoaxial fixation can effectively address the underlying instability, leading to better symptomatic relief and neurological outcomes compared to traditional decompression methods.3,4-17 The findings from these studies consistently demonstrate that atlantoaxial instability is a critical factor in the development of Chiari malformations. Atlantoaxial fixation not only resolves the mechanical instability but also leads to significant symptomatic relief and improved neurological outcomes. ⋯ This surgical Video 1 illustrates a case of a 20-year-old male patient with tonsillar herniation, syringomyelia, atlantooccipital assimilation, atlantoaxial instability, basilar invagination and dorsolumbar scoliosis, who was successfully managed with cervical fixation using a bilateral C1 lateral mass and C2 transpedicular screw construct. This surgery was able to achieve clinical and radiologic improvement without the need for a foramen magnum decompression. The patient consented to the procedure and to the publication of his images.

This bibliometric analysis aimed to map the knowledge network of laminoplasty research. ⋯ This study drew a knowledge map of the top countries, institutions, authors, publications, and journals on laminoplasty over the past 4 decades. The current and future hotspots of laminoplasty focus on sagittal balance, comparison between other surgery in outcomes and complication, and axial symptoms in laminoplasty.

Navigating Challenges and Embracing Opportunities: The Outlook of Functional Neurosurgery in Africa.
This narrative review explores the current landscape of functional neurosurgery in Africa, focusing on the challenges and opportunities facing the field. Drawing upon existing literature and expert insights, the review highlights the scarcity of resources, including trained personnel, infrastructure, and specialized equipment, as major hurdles impeding the widespread adoption of advanced neurosurgical techniques. ⋯ Moreover, the review underscores the significance of addressing cultural beliefs and stigmas surrounding neurological conditions to ensure equitable access to care and promote acceptance of neurosurgical interventions. By navigating these challenges and embracing emerging opportunities, functional neurosurgery in Africa holds the potential to significantly impact neurological health outcomes and enhance overall well-being.

Review
Predictive modeling of early neurological deterioration in patients with Acute Ischemic Stroke.
Ischaemic stroke is the leading cause of death worldwide, and early neurological deterioration(END) occurs in 20%-40% of patients, which is the main cause of severe neurological deficits and disability, and even increased mortality. The occurrence of END is closely related to the poor prognosis of the patients, so it is important to identify the risk factors for the occurrence of END in patients with AIS and target intervention at an early stage factors and targeted intervention is of great significance. ⋯ Clinical practitioners should closely monitor high-frequency predictors of END in patients. However, the varying quality of current models necessitates the selection of models that balance performance with operational simplicity in clinical practice.
