The U.S. health care sector produces approximately 10% of national greenhouse gas emissions, paradoxically harming human health. Neurosurgery is a resource-intensive specialty that likely contributes significantly, yet literature assessing this impact is absent. We investigate the difference in carbon emissions between spinal versus general anesthesia in lumbar spine surgery. ⋯ This is one of the first known comparative carbon footprint studies performed in neurosurgical literature. We highlight the dramatic carbon footprint reduction associated with using spinal anesthesia and reflect a single neurosurgeon's change in practice from using only general anesthesia to incorporating the use of spinal anesthesia. Within general anesthesia patients, desflurane use was particularly harmful to the environment. We hope that our study will pave the way toward future research aimed at uncovering and reducing neurosurgery's environmental impact.

Distance learning has become increasingly important to expand access to neurosurgical spine education. However, emerging online spine education initiatives have largely focused on residents, fellows, and surgeons in practice. We aimed to assess the utility of online neurosurgical spine education for medical students regarding career interests, knowledge, and technical skills. ⋯ Virtual distance learning for neurosurgical spine education is beneficial for students by enabling career exploration and learning content and clinical skills. Although the overall benefit was lowest for clinical skills, virtual programming could serve as an adjunct to traditional in-person exposure. Distance learning could also provide an avenue to reduce disparities in medical student neurosurgical spine education locally and globally.

Oblique lumbar interbody fusion (OLIF) is known as a minimally invasive technique for disc space augmentation. Motor weakness after OLIF has been known to occur in some cases. This study aimed to report the incidence and potential risk factors for motor weakness following OLIF. ⋯ In our study, vertebral osteophyte length was found to be a potential risk factor for motor weakness after OLIF. For patients with long osteophytes, additional laminectomy following OLIF or another surgical approach for direct decompression should be considered.

The authors sought to investigate if peripheral blood leukocyte profiles on admission differed between perimesencephalic, angio-occult, and aneurysmal subarachnoid hemorrhage cohorts. ⋯ Perimesencephalic subarachnoid hemorrhage exhibits a unique peripheral blood leukocyte profile compared to aneurysmal subarachnoid hemorrhage. Moreover, these preliminary data demonstrate that blood leukocytes may be affected by the burden of cisternal subarachnoid hemorrhage or the presence of a ruptured aneurysm. Further large-scale prospective studies and validation are required to confirm these preliminary findings.

In the present study, we aimed to identify the obliteration outcomes, complications, and predictors in gamma knife radiosurgery (GKRS) treatment of brain arteriovenous malformations (AVMs) at a tertiary center in a developing country in a 15-year experience. ⋯ GKRS is a safe and effective treatment of brain AVMs. The lack of prior AVM hemorrhage, an eloquent location, and higher AVM were unfavorable predictors for post-GKRS obliteration.
