Introduction: Meritocracy, a concept revered as the cornerstone of fairness and equal opportunity, is critically examined in the context of neurosurgery. This article challenges the notion that success in this demanding field is solely determined by individual abilities and effort. It reveals that factors such as background, gender, and socioeconomic status significantly influence one's career trajectory.

Most pre-existing models are expensive, so we felt a need to develop a real-life model using 3D printing technology to train in endoscopic third ventriculostomy.
Methods: The brain model was made using a 3D-printed resin mold from patient-specific MRI data.
Cadaveric models remain an essential part of medical training across all specialties. Due to their scarcity, high costs, and possible health hazards, there is a need for more accessible and affordable alternatives, especially in low-resource settings. We introduce cost-effective and easily replicable three-dimensional (3D) printed models to help democratize access to hands-on neuroanatomy education.

Objective: The study aimed to provide familiar Oswestry Disability Index (ODI), visual analog scale (VAS) back, and VAS leg effect size (ES) data following endoscopic decompression for sciatica-type back and leg pain due to lumbar herniated disc, foraminal, or lateral recess spinal stenosis.
Background: Higher-grade objective clinical outcome ES data are more suitable than lower-grade clinical evidence, including cross-sectional retrospective study outcomes or expert opinion to underpin the ongoing debate on whether or not to replace some of the traditional open and with other forms of minimally invasive spinal decompression surgeries such as the endoscopic technique.

Study Design: A design-agnostic standardized effect meta-analysis of 48 randomized, prospective, and retrospective studies on clinical outcomes with spinal endoscopic and interspinous process spacer (IPS) surgery.
Objective: The study aimed to provide reference set of Oswestry Disability Index (ODI) and visual analog scale (VAS) effect size data for back and leg pain following endoscopic and IPS decompression for lumbar herniated disc, foraminal, or lateral recess spinal stenosis.
Background: Mechanical low back pain following endoscopic transforaminal decompression may be more reliably reduced by simultaneous posterior column stabilization with IPS.
Background: Recent severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) pandemic represents an important negative impact on global training of neurosurgery residents. Even before the pandemic, discrimination is a challenge that neurosurgical residents have consistently faced. In the present study, we evaluated discriminatory conditions experienced by residents during their neurosurgical training in Mexico before the SARS-CoV-2 pandemic.

Moreover, the current coronavirus disease 2019 (COVID-19) pandemic may also show a negative impact on burnout levels in neurosurgery residents. This study aims to evaluate burnout, discrimination, and mistreatment in neurosurgical residents training in Latin America during the severe acute respiratory syndrome coronavirus 2 era.

Neurosurgery has not been the exception. Therefore, we investigated the challenges and influence of female neurosurgeons in Mexico.

Recent studies have reported the detrimental effects of the pandemic on neurosurgery residents in North America, Asia, and Italy. However, the impact of the pandemic on neurosurgical training in Latin America and Spain has not yet been reported.

Background: The Latin American Federation of Neurosurgical Societies (FLANC) is a nongovernmental, nonprofit civil association, founded to promote neurosurgery in the Latin American countries. The American College of Surgeons and American Association of Neurological Surgeons has recommended a ratio of 1 neurosurgeon/100,000 inhabitants. We aimed to estimate the neurosurgical workforce of the FLANC in 2020.

Current series report good to excellent results, but a number of patients suffer from dysphagia with reported rates as high as 80%.
Materials And Methods: Retrospective cohort of patients undergoing ACSS (anterior cervical discectomy and fusion [ACDF]; and arthroplasty, total disc replacement [TDR]) from 2013 to 2017 by a single surgeon.

Background: Contributions from Latin America to the global literature are scarce; until 2011, spine surgeons had published 320 articles in indexed journals.
Methods: This systematic review evaluates the scientific production of the Mexican Association of Spine Surgeons (Asociación Mexicana de Cirujanos de Columna-AMCICO) from its inception in 1998 to 2018 with the PRISMA statement using PubMed and Google Scholar search engines. The inclusion criteria were spine-related articles in indexed journals providing any (or no) level of evidence with ≥1 AMCICO member as an author.
Background: Intraspinal tumors are 10 to 15 times less common than brain tumors. The midline approach with extensive laminectomies represents the current gold-standard for resection, causing instability, muscle damage, and kyphosis among other well-known complications. Minimally invasive series reported their results using retractor-based systems.

Study Design: Retrospective comparative clinical study.
Purpose: This study aimed to assess paraspinal muscle atrophy in patients who underwent minimally invasive transforaminal lumbar interbody fusion (MI-TLIF) and unilateral pedicle screw fixation using a novel contralateral intact muscle-controlled model.
Overview Of Literature: The increased incidence of paravertebral lumbar muscle injuries after open techniques has raised the importance of implementing minimally invasive spine surgical techniques using tubular retractors and minimally invasive screw placement.

It is thought that the pain is caused by compression and by other local chemical mediators that are present in the area of interaction between the root and the disc.With the objective of treating patients suffering from this syndrome and with a percutaneous minimally invasive approach, we designed a mixed technique: percutaneous automated nucleotomy plus nucleolysis and periradicular infiltration with ozone.
