Intramedullary spinal cord lipomas without spinal dysraphism are rare. Although they are benign tumors, they can cause significant neurological deficits. Their tight adherence to the spinal cord presents a challenge for resection. Therefore, we review our institutional experience treating adult patients with intramedullary lipomas in the absence of dysraphism and report long-term outcomes after resection. ⋯ Subtotal resection is a safe and effective treatment. Detethering of the spinal cord, resection of exophytic components, and tumor debulking can improve symptoms and prevent further deterioration in most cases. The resection can be assisted using a laser to vaporize the fatty tissue of the lipoma without physical manipulation of the spinal cord.

Currently, there is a unanimous opinion that the first line of the treatment of insular gliomas is microsurgical removal.1-3 At the same time, surgery of insular glial tumors remains a challenge because of the complex anatomy of the insular region. Among the most crucial anatomical structures are branches of the middle cerebral artery (MCA), lenticulostriate arteries (LSAs), and corticospinal tract.4 Surgery of the insular glioma becomes much more complicated in cases when the tumor extends to the anterior perforated substance, which, according to our data, occurs in 29,1% of cases.5 We present a 33-year-old woman with a history of generalized seizures (Video1). ⋯ The video demonstrates the technique of a Sylvian fissure dissection, manipulations with MCA branches and LSA, removal of the tumor from the region of the anterior perforated substance, and a discussion of surgical nuances and safety aspects. The most challenging part of the operation was to identify and protect the LSAs.6 Advanced microsurgical techniques, and the correct patient selection for surgical treatment, are cornerstones for a successful outcome and provide an acceptable frequency of postoperative neurologic deficits in patients who undergo surgery of insular gliomas through the transsylvian approach.

The aim was to conduct a comprehensive bibliometric analysis of meningioma research, focusing on publication trends, top authors, universities, countries, and thematic analysis of keywords. ⋯ Our findings may provide insights into the evolution of meningioma research and its scholarly impact. The analysis underscores the pivotal contributions of top authors and institutions, outlines thematic research trends, and highlights areas of significant interest and growth in the field. Our study may contribute to understanding the landscape of meningioma research, guiding future research directions and collaborations.

To investigate the biomechanical properties of pedicle screw reinsertion along the same trajectory in a previously validated synthetic bone model. ⋯ Despite a significant decrease in insertion torque, there is no significant loss of pedicle screw performance when a screw is removed and reinserted along the same trajectory.

To assess the national and regional trend in the prevalence of lumbar spondylolysis and isthmic spondylolisthesis for adolescent males in South Korea from 2015 to 2022. ⋯ The prevalence of lumbar spondylolysis among adolescent men has increased, whereas isthmic spondylolisthesis has shown a decline over a consecutive 8-year period. The trends in prevalence for both lumbar spondylosis and isthmic spondylolisthesis were similar across the regions in South Korea. Notably, there was a significant correlation between the prevalence of isthmic spondylolisthesis and the rate of alcohol consumption in adolescent men.
