To explore related factors that influence time to recurrence and prognosis of gliomas. ⋯ This comprehensive analysis revealed that initial World Health Organization grade and Ki-67 proliferative index were independent prognostic factors that predict the time to recurrence of glioma in patients after first surgery.

Case Reports
Melorheostosis causing compression of the common peroneal nerve at the fibular tunnel: a case report.
Melorheostosis is a bone hyperostosis disorder characterized by flowing bone thought to occur in a sclerodermal distribution. These bony lesions often arise in soft tissues adjacent to joints. Pain arises from joint limitations and impingements, but diffuse pain can also occur. ⋯ Melorheostosis is a rare bone overgrowth syndrome that can lead to joint mobility limitations and pain. In specific locations, it can also lead to tethering and symptomatic compression of the peripheral nerves.

In situations in which posterior atlanto-occipital fixation might not be possible or might require supplemental fixation, anterior fixation might add stability in obtaining arthrodesis. The present study aimed to provide a radiographic evaluation of the safety and feasibility in the anterior approach. ⋯ The ideal entry angle for anterior atlanto-occipital fixation ranges from 41.0° to 55.0°, with a safe screw length from 30.9 to 31.3 mm. The potential success rate could reach >90%.

Microsurgical management of blood blister aneurysms of the internal carotid artery is challenging because of the special characteristics of these aneurysms. We reviewed our diverse surgical methods with long-term clinical and radiologic follow-up. ⋯ Direct clipping is ideal if possible; however, direct clipping is challenging in most blood blister aneurysms. Assisted clipping with cotton is mainly used and could be an effective technique for reinforcement of the friable wall, with good clinical outcomes in our series. Moreover, suturing followed by wrapping-clipping is also useful for managing intraoperative rupture.

To establish microscope-based augmented reality (AR) support for degenerative spine surgery. ⋯ Reliable microscope-based AR support is possible because of automatic registration based on intraoperative imaging. Application of AR in degenerative spine surgery has a big potential; it might be especially helpful in complex anatomical situations and resident education.
