Workplace violence (WPV) against neurosurgeons is an understudied phenomenon, as previous research has focused on high-risk specialties like emergency medicine and psychiatry. We sought to fill in this gap in the literature by determining the frequency and type of WPV that neurosurgeons experience. ⋯ WPV is prevalent in neurosurgery at rates comparable with a range of other specialties. Many neurosurgeons feel unsafe in the workplace, with some taking significant actions such as weapon acquisition. An opportunity for education and resources regarding WPV exists, especially among early career and female neurosurgeons.

Over the past 2 decades, management of idiopathic normal pressure hydrocephalus (iNPH) has evolved significantly. In the current study, we sought to evaluate the national prevalence and management trends of iNPH in the United States using a national database. ⋯ We have summarized the national prevalence of iNPH, trends in its management over the previous decade and trends by region and hospital type.

Flow diversion with or without coil embolization has become the first-line treatment for large or giant paraclinoid internal carotid artery intracranial aneurysms. Oftentimes, these sizable aneurysms impose anatomical challenges to endovascular treatment through limiting both distal outflow access and maintenance of distal vessel purchase during catheter reduction, which are required for successful stent placement. Various strategies to obtain and maintain distal access within the parent vessel have been described previously; however, new techniques may need to be employed when more standard maneuvers fail. ⋯ Giant, wide-neck aneurysms present treatment challenges that may require using adjunctive devices and advanced endovascular techniques. When routine strategies for gaining distal outflow access fail, the Ricochet-Scepter technique is a viable option for achieving distal access.

We sought to investigate the changed position of thoracic aorta relative to spine in patients with left thoracic scoliosis and to analyze the potential risks of thoracic aorta injury from pedicle screw insertion in these patients. ⋯ The thoracic aorta often lies anteriorly to the left pedicle screw trajectory in normal subjects, especially in the lower thoracic region. However, the thoracic aorta moves to the right side in patients with left thoracic scoliosis, making a large proportion of patients at risk of injury from right pedicle screw insertion in the apical region.

Narrowing of intervertebral space height (ISH) is an important pathological change in degenerative spinal disease, and ideal intraoperative distraction and postoperative intervertebral space maintenance is one of the most expectant goals pursued by spinal surgeons. The effect of postoperative ISH changing on the clinical and radiological outcomes after cervical disc replacement is not fully understood, however. ⋯ This study revealed that cervical disc replacement cannot maintain the intervertebral disc height obtained immediately after surgery. There is no obvious correlation between the change in intervertebral space height and clinical efficacy in the early postoperative stage. Nonetheless, the intervertebral disc height may affect the NDI index 1 year after surgery. If the postoperative intervertebral space height change can be maintained at 2-4 mm at 1 year, satisfactory ROM, intervertebral foramen diameter, and relatively low adjacent segment degeneration may be obtained after cervical disc replacement.
