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.

Posttraumatic cerebral venous sinus thrombosis (CVST) is a major complication after head injury. Impaired venous outflow caused by CVST leads to increased intracranial pressure (IICP) refractory to medications and surgical decompression and often results in devastating consequences. Currently, there is no consensus on the treatment strategy. ⋯ Acute cerebral sinus thrombosis caused by trauma may result in malignant IICP refractory to medications and surgical decompression. We have demonstrated that endovascular angioplasty and sinus stenting are effective in restoring venous outflow and reducing intracranial pressure. We have also demonstrated that appropriate and timely interventions are important to ensure quick and good recovery in patients with CVST.

Cranioplasty is a technically simple procedure intended to repair defects of the skull to provide protection after craniectomy, improve functional outcomes, and restore cosmesis. Several materials have been used for the restoration of skull defects, including autologous bone grafts (AGs), polymethyl methacrylate (PMMA) flaps, and titanium mesh (T-mesh). However, the long-term results of cranioplasty after use of these materials are controversial. ⋯ Complications after cranioplasty are high, and the various types of cranioplasty materials used are associated with different complications. Surgeons need to be aware of these potential complications and should choose the appropriate material for each individual patient.

Novel Nerve Transfers for Motor and Sensory Restoration in High Cervical Spinal Cord Injury: Report of 2 Cases.
Tetraplegia caused by cervical spinal cord injury is devastating for patients and represents a significant public health problem in both developed and developing countries. Improved functional outcomes after nerve transfers are increasingly reported in the literature, but thus far, no options exist for injuries above the C5 level. ⋯ We describe 2 successful cases of the first and to date only option for motor and sensory reinnervation in high cervical spinal cord injuries. These procedures provide a robust nerve transfer option capable of improving quality of life in tetraplegic patients. There may be a significant undertreated population of patients with cervical spinal cord injury patients in the United States who were previously considered outside the window for benefiting from nerve transfers but who would benefit from these techniques.

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.
