Current literature lacks objective criteria to determine surgical management in patients with ankylosing spondylitis who sustain cervical fractures. The purpose of our study was to analyze the determinants for stratifying surgical approach, evaluate the outcome in patients, and postulate a management strategy. ⋯ Our study provides insights into management of cervical spine fractures in ankylosing spondylitis patients. A fracture displacement ≤2 mm may be successfully managed by an anterior approach, while the posterior approach may be beneficial in similar fractures warranting instrumentation extending to the thoracic spine. All other fractures warrant a combined surgical approach.

Case Reports
Radial Forearm Free Flap with Parapharyngeal Pedicle Corridor for Reconstruction of Anterior Skull Base Defects.
The radial forearm free flap (RFFF) is an indispensable tool for the reconstruction of a range of defects, including those of the skull base. Several options for routing of the RFFF pedicle have been described, and the parapharyngeal corridor (PC) has been proposed as an option and employed for a nasopharyngeal defect. However, there are no reports of its use for the reconstruction of anterior skull base defects. The objective of this study is to describe the technique for free tissue reconstruction of anterior skull base defects using the RFFF and routing of the pedicle via the PC. ⋯ The PC is an option for routing the pedicle during the reconstruction of anterior skull base defects. When the corridor is prepared as described in this case, a direct route exists from the anterior skull base to cervical vessels, simultaneously maximizing the reach of the pedicle and minimizing the risk of kinking.

High-grade migrated lumbar disc herniation (LDH) such as up-migrated and down-migrated discs are challenging pathologies to treat. High-grade migrated discs are usually sequestered and situated adjacent to the medial pedicle wall. This can be easily addressed if the pedicle is used as an access route. The authors present a retrospective case series of high-grade migrated LDH treated using a full endoscopic transforaminal approach. ⋯ The full endoscopic transpedicular approach is a good option for treating highly migrated LDH. Surgical planning, including pedicle morphometry and the angle of the approach, should be undertaken preoperatively for the best results.

Widespread use of carmustine wafers (CWs) to treat high-grade gliomas (HGG) has been limited by uncertainties about their efficacy. We sought to assess the outcome of patients after newly diagnosed HGG surgery with CW implantation and search for associated factors. ⋯ OS of patients with newly diagnosed HGG who underwent surgery with CW implantation is better in young patients, those of the female sex, and for those who complete concomitant chemoradiotherapy. Redo surgery for HGG recurrence also was associated with prolonged survival.

Observational Study
The effect of COVID-19 in a university hospital neurosurgery clinic comparison to pre-pandemic period: a retrospective study with 6 months of data.
The coronavirus disease 2019 (COVID-19) pandemic affected all countries' health systems and people's lifestyles. In this study, we aimed to investigate its effects in a university hospital neurosurgery clinic. ⋯ The pandemic and restrictions affected negatively the health system and people's access to healthcare. Our retrospective observational study aimed to evaluate these effects and take lessons for the next similar situations. People's access to health care should be considered when lockdown restrictions.
