Acute complex C2 vertebral body fracture specifically does not involve the odontoid process or C2 pars interarticularis. External stabilization can be effective but may prolong healing and increase morbidity. Many traditional surgical techniques can achieve internal stabilization at the expense of normal cervical motion. We describe direct surgical C2 pedicle screw fixation as an option for managing acute complex C2 vertebral body fracture. ⋯ Direct pedicle screw fixation of acute complex C2 vertebral body fracture appeared to be safe and effective in our 3 patients. It may provide a more-efficient and less-morbid treatment than halo brace or cervical collar immobilization in some patients.

Although age already is known as a crucial factor affecting the functional outcome after a hemicraniectomy for malignant hemispheric infarction, previous studies have used arbitrary age cut-offs of 50, 60, or 70 years. Therefore, this study investigated predictors of the functional outcome after a hemicraniectomy and attempted to determine the critical age for an unfavorable functional outcome. ⋯ Advanced age was identified as a significant predictor of an unfavorable outcome and functional dependency. The PPV of a patient age >58 years and >67 years for predicting an unfavorable outcome with functional dependency was 82% and 100%, respectively.

In meningioma, correlation of brain invasion with prognosis and clinical variables remains controversial. ⋯ Brain invasion and its patterns are correlated to gender. In contrast to the current WHO classification, invasion was associated with recurrence only after gross total resection and not independent of further histopathologic criteria of atypia.

To evaluate the long term C1-C2 fusion rates, fracture healing and functional outcomes in geriatric patients with type II odontoid fracture treated with posterior fixation with polyaxial C1 lateral mass screws and C2 pars screws. ⋯ This study adds to the evidence that posterior atlantoaxial fixation with polyaxial C1 lateral mass screws and C2 pars screws is a safe and effective surgical option in the treatment of odontoid fractures including long-term stability.

The nasoseptal flap (NSF) has been shown to be a mainstay in the reconstruction of skull base defects. We evaluated the efficacy and complications of NSF in patients with a history of septal surgery who had the potential risk of tearing and poor vascularity. ⋯ There was no difference in rate of CSF leakage or flap integrity between the 2 groups. Therefore, NSF for skull base reconstruction is feasible in patients with a history of septal surgery.
