The increasing challenges facing the training of future neurosurgeons have led to continued development of simulation-based training, particularly for neurosurgical subspecialties. The simulators must be scientifically validated to fully assess their benefit and determine their educational effects. In this second part, we aim to identify the available simulators for spine, pediatric neurosurgery, interventional neuroradiology, and nontechnical skills, assess their validity, and determine their effectiveness. ⋯ With increasing simulators, there is a need for more validity studies and attempts to investigate translational outcomes to the operating theater when using these simulators. Nontechnical skills training is notably lacking, despite demand within the field.

Spinal epidural hematoma associated with epidural metastasis after minor trauma: a case report.
Spinal epidural hematoma associated with epidural metastasis is very rare. Epidural hematoma is unusual in itself, and metastatic epidural tumors do not commonly occur. ⋯ To our knowledge, spinal epidural hematoma accompanied by epidural metastasis has not previously been reported. We hypothesized that tissue invasion of malignant neoplasms may cause hemorrhagic conditions. The presence of a tumor should therefore be considered in the differential diagnosis of cases of epidural hematoma.

Adjacent segment disease (ASD) is a long-term complication of lumbar spinal fusion. This study aims to evaluate demographic and operative factors that influence development of ASD after fusion for lumbar degenerative pathologies. ⋯ Results of our study show that the most important surgical factor contributing to ASD is decompression beyond fused levels. Hence caution should be exercised when decompressing spinal segments outside the fusion construct. Conversely, spondylolisthesis patients had the lowest ASD rates in our cohort.

Interest in endoscopic transnasal access has increased with continued technological advances in endoscopic technology. The goals of this study were to review the normal anatomy in transnasal endoscopic neurosurgery and outline the anatomical basis for an expanded surgical approach. Defining anatomical aspects of surgical endoscopy helps guide the surgeon by defining normal anatomy of the access vector. ⋯ Thorough knowledge of topographic anatomy of the craniovertebral junction is required for performing minimal-risk surgical intervention in this region. It is important to know all anatomical aspects of the transnasal approach in order to reduce the risk of damage to vital structures. Transnasal endoscopic surgery of the craniovertebral junction is a relatively new direction in neurosurgery; therefore, anatomical studies such as the one described in this article are extremely important for the development of this access method.

To elucidate the correlation between changes in spinal/pelvic sagittal parameters and clinical treatment outcomes after oblique lumbar interbody fusion (OLIF). ⋯ OLIF for treatment of LDD had significant clinical outcomes, effectively restored the spinal/pelvic sagittal balance, and helped to improve the patients' clinical conditions.
