To determine characteristics of Latin American (LA) productivity in spine surgery published worldwide between 2004 and 2021 compared between periods and global literature. ⋯ This scientometric study is one of the first regional evaluations worldwide. The number of publications in the spine surgery field in Latin America has continued to increase over evaluated decades from 58.3 per year to 108, and a 1.79-fold increase between the most productive years for each decade. Brazil is still the greatest contributor (51.14%), with Mexico (26.40%) and Argentina (8.64%) as growing contributor countries. Most publications were classified as Level of Evidence 4, and this result reflects the importance of continuous research development in the quality of research for our region.

Low- and middle-income countries experience numerous challenges in the provision of neurosurgical care. However, limited information exists on the neurosurgical workforce and the constraints under which care is delivered in Ghana, West Africa. ⋯ The provision of neurosurgical care in Ghana has come a long way since the 1960s. However, the neurosurgical community continues to face significant challenges. Alleviating these barriers to care will call for systems-level changes that allow for the prioritization of neurosurgical care within the Ghanaian health care system.

Randomized Controlled Trial
A pilot study comparing algorithmic adaptive conventional stimulation to high dose stimulation in chronic pain patients.
Spinal cord stimulation is an effective method of treatment for chronic pain. We previously showed that programming using accelerometry was advantageous for paresthesia-based stimulation. However, programming can be labor intensive. ⋯ In this pilot study, we demonstrated that HD stimulation at T9-10 is superior to algorithmic programming of paresthesia-based stimulation. These results compared with our previous work with shuffle suggest that paresthesia-based stimulation may necessitate stimulation of additional contact locations and additional programming to optimize. This algorithmic programming of paresthesia-based stimulation continues to warrant exploration.

Virtual reality (VR) and augmented reality (AR) are rapidly growing technologies. Both have been applied within neurosurgery for presurgical planning and intraoperative navigation, but VR and AR technology is particularly promising for the education of neurosurgical trainees. With the increasing demand for high impact yet efficient educational strategies, VR- and AR-based simulators allow neurosurgical residents to practice technical skills in a low-risk setting. ⋯ During that time, several devices had become rapidly adopted by neurosurgeons, and some programs had begun to incorporate them into the residency curriculum. With ever-improving technology, VR and AR are promising additions to a multi-modal training program, enabling neurosurgical residents to maximize their efforts in preparation for the operating room. In this review, we outline the historical development of the VR and AR systems that are used in neurosurgical training and discuss representative examples of the current technology.

Meta Analysis
Efficacy and safety of Goel-Harms technique in upper cervical spine surgery: a systematic review and meta-analysis.
The main purpose of this systematic review and meta-analysis was to estimate the incidence of implant-associated complications and fusion rates for the Goel-Harms technique (GHT) and to show potential factors affecting the complications and nonunion development. ⋯ The Goel-Harms technique is a promising method of C1-C2 fusion, with a relatively low nonunion and VA injury rate. It can be performed safely without C-arm or navigation system assistance. Transpedicular screw insertion trajectories to the C1 and C2 vertebrae were safest regarding VA injury and blood loss volume. Further comparative studies of various C1-C2 stabilization methods with a high level of significance should be carried out to identify the optimal approach.
