Neuroendoscopic surgeries require specialized equipment, which may not be universally available or equitably distributed in most neurosurgical units of resource-limited healthcare systems. This review reports on the use of locally available resources to perform safe ventricular endoscopic surgeries in patients with hydrocephalus and cystic craniopharyngioma in a resource-limited healthcare system. ⋯ Patients accessing neurosurgical care in resource-limited healthcare systems can benefit from safe and successful intraventricular endoscopy. However, this may require the innovative use of locally available resources that can be adapted to local neurosurgical needs.

Razorback deformity with stiff thoracic scoliosis creates a complex three-dimensional deformity. Posterior spinal fusion (PSF) and thoracoplasty can correct rib hump deformity and improve patient satisfaction. However, conventional thoracoplasty may impair pulmonary function and increase complications. We present a modified thoracoplasty (MTP) technique for addressing rib hump deformity in stiff thoracic scoliosis patients, emphasizing its clinical efficacy and safety. ⋯ MTP provides enhanced correction of thoracic curve and rib hump deformity without significantly increasing pulmonary function impairment or complication rates. It also improves patients' self-image, making it a valuable addition to PSF in treating stiff thoracic scoliosis with rib hump deformity.

Understanding Adult Central Nervous System Hemangioblastomas: meta-analysis of meta-analysis.
Adult hemangioblastomas (HBs) are rare World Health Organization central nervous system (CNS) grade 1 tumors, particularly affecting the posterior cranial fossa. They exhibit a gender bias, impacting men in their fifth and sixth decades of life and manifesting sporadically or as part of von Hippel Lindau disease. Understanding the intricacies of CNS HBs is crucial for clinical decision-making. ⋯ Adult CNS HBs present with diverse characteristics and clinical manifestations. Surgical intervention remains the mainstay treatment; ongoing research into genetic and molecular mechanisms may enhance our understanding of tumor pathology and lead to improved management strategies in the future.

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.
