Placing the patient in lateral position is an option for implantation of stereoelectroencephalography (SEEG) electrodes that have a posterior entry point. Previous studies reported the accuracy of SEEG electrodes but not specifically in relation to position. The aim of this study was to analyze accuracy of SEEG electrodes by position. ⋯ SEEG leads implanted in lateral position exhibit an accuracy and safety profile in accordance with previous studies. In this cohort, target error was smaller in the lateral position, particularly in noninsular electrodes.

To identify the apical vertebra is relate to the occurrence of vertebral rotatory subluxation (VRS) in degenerative lumbar scoliosis. ⋯ VRS is an important characteristic to consider in degenerative lumbar scoliosis that can affect the coronal and sagittal alignment. The apical vertebra is correlated with the occurrence of VRS; an apical vertebra translation greater than 23.2 mm and apical vertebra tilt angle greater than 11.8° are highly correlate with the occurrence of VRS.

The purpose of this study was to characterize the impact of household income disparities in the survival of patients with non-small cell lung cancer (NSCLC) presenting with brain metastasis on a population-based level. ⋯ This population-based study suggests that living in higher median household income counties is associated with increased survival time and reduced risk of mortality for patients with NSCLC who have brain metastases present at diagnosis, independent of other factors. These findings underscore the importance of ensuring adequate and easy access to care for all patients, irrespective of their economic background.

We sought to evaluate the feasibility and efficacy of spinous process screws in subaxial cervical fixation. ⋯ The spinous process screw fixation technique in the subaxial cervical spine is a viable and effective salvage option for patients in whom conventional posterior fixations were not sufficient and salvage, supplementary techniques were required.

An Easy Adjustable Sling Technique of Ectatic Vertebral Artery Transposition for Microvascular Decompression.
Hemifacial spasm caused by an elongated, tortuous, or enlarged vertebral artery (VA) can be difficult to treat. Greater rates of incomplete cure also have been noted.1-6 In this video, we demonstrate the key steps of a simple and effective adjustable sling technique of an ectatic VA transposition for microvascular decompression. In this patient, an ectatic VA was stacked on the posterior inferior cerebellar artery, and together they compressed the root exit zone (REZ) of the facial nerve. ⋯ We made a small dural incision at the anchor point, where an aneurysm clip was applied to hold the sling securely under tension but not to cause kinking of the VA/posterior inferior cerebellar artery. The patient had no hemifacial spasm immediately after the operation and thereafter. This adjustable sling technique provides an easy and strong hold to maintain an ectatic VA away from the REZ of the facial nerve (Video 1).
