This study aimed to describe the clinical outcome of metastatic epidural spinal cord compression in octogenarians with an acute onset of neurological illness who undergo laminectomy, further assess morbidity and mortality rates, and determine potential risk factors for a nonambulatory outcome. ⋯ Emergent decompressive laminectomy in patients with acute onset of neurological decline and potentially unstable spines improved functional outcome at discharge. Age should not be a determinant of whether to perform surgery; surgery should be performed in older patients when indicated.

Both endoscopic and microsurgery transcortical resection methods are used for colloid cysts of the third ventricle but they have not been compared regarding benefits and pitfalls. ⋯ In our series, the rate of intraoperative hemorrhage was higher with the endoscopic method and GTR was lower, even after adjustment for other factors. This situation could be caused by technological shortcomings and limited space for resection maneuvers and management of complications.

As the literature grows on opioid use, the impact of simultaneous cannabis use has hitherto been mostly unexplored. In this study, we assessed the effects of cannabis use on postoperative opioid utilization in opioid-naive patients undergoing single level fusions of the lumbar spine. ⋯ Compared to noncannabis users, opioid-naive patients who are cannabis users undergoing lumbar spinal fusions are at a higher risk of developing opioid dependence following surgery, despite having decreased daily dosages of opioids overall. Further studies should explore the factors associated with the development of OUD and the details of concurrent marijuana use to effectively treat pain while limiting the potential for abuse.

To evaluate outcomes of sagittal reconstruction of the atlantoaxial lateral mass complex using a modified intra-articular cage fusion technique for treating degenerative atlantoaxial instability. ⋯ Posterior reduction and intra-articular cage fusion with a C2 nerve root preservation technique is effective in treatment of degenerative atlantoaxial instability. Satisfactory reconstruction of the sagittal alignment and the height of atlantoaxial complex can be achieved.

The diagnosis of hydrocephalus is dependent on clinical symptoms and radiographic findings including ventriculomegaly. Our goal was to generate a data set of ventricular volume utilizing non-pathologic computed tomography (CT) scans for adults to help define reference ventricle size. ⋯ We have developed a convolutional neural network that can segment the ventricles on CT scans of adult patients over a range of ages. This network was used to measure the ventricular volume of non-pathologic head CTs to produce reference ranges for several age bins. This data set could be utilized to aid in the diagnosis of hydrocephalus by comparing potentially pathologic scans to reference ventricular volumes.
