Traumatic odontoid fractures (tOFs) in the very elderly are associated with high morbidity and mortality. The best treatment strategy (conservative vs. surgery) is still unclear. ⋯ Our research was a retrospective cohort study, Level III.

The Trans-Visible Navigator: a see-through neuronavigation system using augmented reality.
The neuronavigator has become indispensable for brain surgery and works in the manner of point-to-point navigation. Because the positional information is indicated on a personal computer (PC) monitor, surgeons are required to rotate the dimension of the magnetic resonance imaging/computed tomography scans to match the surgical field. In addition, they must frequently alternate their gaze between the surgical field and the PC monitor. ⋯ The main advantage of the present system is that it achieves volumetric navigation in contrast to conventional point-to-point navigation. It extends augmented reality images directly onto real surgical images, thus helping the surgeon to integrate these 2 dimensions intuitively.

The outcome of flow diversion for middle cerebral artery (MCA) aneurysms, one of the most common sites for intracranial aneurysms, has not been defined thoroughly. We assessed our outcomes in MCA aneurysms (MCAAs) treated by flow diversion, i.e., with either dedicated flow diverters or telescopic stents. ⋯ In this series, flow diversion for the treatment of MCAAs was safe, was effective in the treatment of fusiform MCAAs, and was not as effective at mid-term for MCA bifurcation aneurysms. Unsatisfactory occlusion rate in bifurcation aneurysms likely results from residual filling of the aneurysms in cases in which the jailed side branch remains patent.

To evaluate in a comprehensive biomechanical study the influences of fixed C1-C2 and different C1-C2 angles on the range of motion (ROM) and the intradiscal pressure (IDP) of subaxial cervical spine. ⋯ To maintain a physiologic sagittal alignment of subaxial cervical spine, C1-C2 should be fixed in the neutral position or a relatively smaller angle instead of a more lordotic position.

This prospective cohort-designed study was performed to verify whether higher levels of serum lipoprotein(a) (Lp(a)) could be a risk factor for deep vein thrombosis (DVT) in Chinese patients with spinal cord injuries (SCI). ⋯ Increased serum Lp(a) levels were independent predictors of DVT in patients with SCI in China, suggesting a possible role of Lp(a) in the pathogenesis of DVT.
