Realistic, safe, and efficient modalities for simulation-based training are highly warranted to enhance the quality of surgical education, and they should be incorporated in resident training. The aim of this study was to develop a patient-specific virtual cerebral aneurysm-clipping simulator with haptic force feedback and real-time deformation of the aneurysm and vessels. ⋯ We have successfully developed a virtual aneurysm-clipping simulator. Next, we will prospectively evaluate this device for surgical procedure planning and education.

Spine surgeons are exposed to high amounts of radiation from fluoroscopic procedures during their lifetime. In this study, we evaluated spine surgeons' knowledge of and attitude regarding radiation exposure during spine surgery. ⋯ Future efforts toward implementing educational programs in Latin America focused on safety strategies are needed to minimize intraoperative radiation exposure.

Cortical ependymomas (CEs), supratentorial ependymomas that selectively involve the cerebral cortex, are relatively rare neoplasms that have not been extensively described. The purpose of our study was to identify the clinical features, radiologic characteristics, and treatment of a series of such tumors. ⋯ CEs are a rare subset of supratentorial ependymomas that selectively involve the cerebral cortex. Most CEs are low grade and present with seizures. Anaplastic CEs show a greater recurrence rate and a relatively poor prognosis. Gross total resection with or without adjuvant radiotherapy is currently the optimal treatment for CEs. CEs seem to have a more favorable prognosis than other supratentorial ependymomas.

To evaluate short-term efficacy and safety of percutaneous transforaminal endoscopic discectomy (PTED) in treatment of symptomatic adjacent segment disease (ASD) after lumbar fusion in elderly patients >65 years old. ⋯ PTED demonstrated satisfactory short-term efficacy and safety in management of ASD after lumbar fusion in patients >65 years old. PTED may be an alternative choice for elderly patients with ASD after lumbar fusion.

In the treatment of acute ischemic stroke (AIS), patients need to be selected for mechanical thrombectomy (MT) in the acute phase. Selection criteria vary, however, depending on the patient's situation. This study investigated the effectiveness of a noncontrast computed tomography and symptom-based protocol for selecting patients for MT. ⋯ Noncontrast computed tomography and symptom-based selection of MT to treat AIS can be useful for achieving better neurologic recovery in a subgroup of patients. This approach could broaden the use of MT.
