Stereotactic body radiotherapy (SBRT) has been established as a safe and effective treatment modality for control of long-term pain and tumor growth. However, few studies have investigated the efficacy of postoperative SBRT versus conventional external beam radiation therapy (EBRT) in extending survival within the context of systemic therapy. ⋯ In patients who do not receive systemic therapy, treatment with postoperative SBRT may increase survival time compared with patients not receiving SBRT.

Intracranial aneurysms (IAs) are common cerebrovascular diseases with high rates of mortality and disability. With the development of endovascular treatment technologies, the treatment of IAs has gradually turned to endovascular methods. However, because of the complex disease characteristics and technical challenges of IA treatment, surgical clipping still plays an important role. However, no summary has been performed of the research status and future trends in IA clipping. ⋯ The results from our bibliometric study have clarified the global research status of IA clipping between 2001 and 2021. The United States contributed the most publications and citations, and World Neurosurgery and Journal of Neurosurgery can be considered landmark journals in this field. Studies regarding occlusion, experience, management, and subarachnoid hemorrhage will be the research hotspots related to IA clipping in the future.

Amazonas is the largest state in Brazil, covering an area of 1,559,159.148 km2 and primarily occupied by the Amazon rainforest. Fluvial and aerial transport are the primary means of transportation. Studying the epidemiologic profile of patients transported by neurologic emergencies is essential because there is only 1 referral center hospital serving approximately 4 million inhabitants in Amazonas. ⋯ Air transportation for neurologic evaluation is essential in Amazonas. However, most patients did not require neurosurgical intervention, indicating that investments in medical infrastructures, such as computed tomography scanners and telemedicine, may optimize health costs.

Lumbosacral plexus tumors are uncommon, and because of their deep location and proximity to critical nerves subserving lower extremity function, understanding surgical approaches and short-term outcomes is important. ⋯ Indications for surgery include pain and/or neurological symptoms attributable to the lesion or large size if asymptomatic. Careful study of preoperative imaging is necessary to determine the best approach. Intraoperative nerve stimulation is essential to preserve function and guide extent of resection in benign tumors.

This paper reports a new three-dimensional (3D)-printed osteotomy guidance system to assist thoracolumbar kyphosis osteotomy and describe the guide plate design, surgical procedure, and short-term clinical results. ⋯ The preliminary clinical application of the new 3D osteotomy guidance system shows that it provides an effective connection between the guide plates and a clinically operative visual field. The use of a 3D guide plate system for positioning and guidance is helpful to complete preoperative planning of anterior and middle column vertebral body osteotomy. However, the efficacy of this method should be compared to that of the free-hand technique with long-term follow-up.
