Case Reports
Rescue implantation of expandable cages for severe osteolysis and cage dislocation in the lumbosacral junction.
Osteolysis and implant loosening are commonly encountered problems after spinal instrumentation. ⋯ We propose the use of cages with the ability of ventral distraction in similar rescue interventions with cage dislocation and bone resorption. This may prevent a second surgery via a ventral approach.

Resident education in the United States and elsewhere has undergone significant changes in recent years owing to work hour restrictions, requiring didactics to fit within a limited schedule, while being increasingly effective at accomplishing educational goals. ⋯ Residents can be exposed to both clinical material and specialty-specific mores using focused and intentional educational techniques.

The aim of this international survey was to investigate the current management of patients undergoing surgery for chronic subdural hematoma (cSDH) treated with low-dose acetylsalicylic acid (ASA). ⋯ Most neurosurgeons discontinue ASA treatment for at least 7 days in the perioperative period of surgical evacuation of cSDH, even though recent studies show that early ASA resumption might be safe. Thrombosis prophylaxis is administered by only 60%, even though patients with cSDH are at high risk of developing thromboembolic complications. Better evidence and guidelines are warranted because the incidence of patients with cSDH under the treatment of ASA is increasing.

The frontal aslant tract is a deep frontal pathway connecting the superior frontal gyrus (SFG) to Broca area. This fiber is assumed to be associated with language functions, especially speech initiation and spontaneity. The aim of this study was to electrophysiologically investigate this network using corticocortical evoked potentials (CCEPs). ⋯ The present study demonstrated a corticocortical network connecting Broca areas and SFG in a reciprocal manner. Our findings might provide new insight into language and motor integration.

Atypical meningioma has a higher recurrence rate than benign meningioma. The mainstay of treatment is surgery with or without radiation therapy (RT). The objective of this study was to investigate progression-free survival (PFS) and factors associated with postoperative recurrence in patients with atypical meningioma. ⋯ Tumor location and pial invasion were significantly correlated with increased incidence of tumor recurrence, and postoperative RT was found to be significantly associated with decreased tumor progression and recurrence.
