Degenerative lumbar spinal stenosis (DLSS) carries a high risk of morbidity and represents a financial burden to society. A late diagnosis can lead to severe disability. Although lumbar decompressive surgery has been widely used worldwide, the proper preoperative factors to define the ideal candidates for decompression are missing. ⋯ Our findings have indicated that the ideal candidate for surgery will have the following preoperative characteristics: Schizas grade D, no signs of peripheral polyneuropathy, body mass index <30 kg/m2, symptom duration of <2 years, gait autonomy <100 m, no radicular deficits, 1 level of stenosis, and an American Society of Anesthesiologists score of 1, 2, or 3.

To describe a novel system workflow to design and manufacture patient-specific three-dimensional (3D) printing jigs for single-stage skull bone tumor excision and reconstruction and to present surgical outcomes of 14 patients. ⋯ The computer-aided design/computer-aided manufacturing system described allows definitive preoperative planning and fabrication for treatment of skull bone tumors. Apparent benefits of the method include more accurate determination of surgical margins and better oncological outcomes.

To correlate the presence of objectively measured wall enhancement on high-resolution vessel wall imaging (HR-VWI) with the clinical predictive scales PHASES, ELAPSS, and UIATS. ⋯ Enhancing UIAs score higher in PHASES and ELAPSS scales. This association is largely explained by aneurysm size, aspect, and size ratios. Morphologic UIA features should be accounted for in clinical predictive scales of aneurysm instability.

Dumbbell-shaped thoracic tumors usually arise from neurogenic elements within the spinal canal and are characterized by involvement of both spinal canal and posterior thoracic cavity. The tumor mass becomes frequently very large growing inside and outside of the spinal canal, through the connection of the neural foramen, involving the surrounding structures. Most of the dumbbell tumors are peripheral nerve sheath tumors, of which neurofibromas and schwannomas represent the vast majority. ⋯ However, these operations have significant approach-related morbidity; therefore, in the last decades, thanks to the constant progress of technological devices, minimally invasive techniques have been increasingly used for the surgical management of spinal tumors. In this surgical video (Video 1), we present a minimally invasive, single-step posterolateral approach through a small costotransversectomy (centered with echography and fitted with spine navigation) for the surgical management of a giant dumbbell thoracic neurofibroma. The usefulness of current technology guiding the surgical procedure is underlined with special emphasis.

Over the past several years there has been a dramatic increase in the implementation of telemedicine technology to aid in the delivery of care across community, inpatient, and emergency settings. This technology has proved valuable for acute life-threatening clinical scenarios. We aimed to pilot a novel neurosurgical telemedicine program within an academic tertiary care center to assist in consultation of patients with high-grade intracranial hemorrhage (ICH) (ICH score 4, 5). ⋯ The program proved feasible and several areas in need of improvement within the health system were identified. Emergency physicians reported comfort with the process, program effectiveness, and improved access to care by implementation of this program.
