Posterior fixation without fusion can treat thoracolumbar and lumbar traumatic fractures effectively in certain cases. However, whether patients benefit from implant removal and the correlation between the range of motion (ROM) of the involved segments and the removal time have not been determined. ⋯ Immobilization of the involved segments over 24 months may lead to loss of ROM. Regained segmental ROM is correlated negatively with implant removal time, and removal within 12 months promises a better ROM and quality of life.

The authors present the case of a 52-year-old male with a history of new-onset seizures who presented in status epilepticus. Computed tomography and magnetic resonance imaging demonstrated an olfactory groove mass. ⋯ Postoperative and follow-up course has been unremarkable, with early postoperative imaging demonstrating no residual tumoral mass. The operative video highlights the advantages of using the microinspection tool for the visualization of deep lesions.

To investigate influences of spinopelvic parameters, such as lumbar lordosis (LL) angles, pelvic incidence, sacral slope, pelvic tilt, and sagittal vertical axis, on development of the proximal junctional failure fracture type after posterior instrumentation. ⋯ In our experience, appropriate LL and lower PLK should be obtained at surgery to prevent development of instrumented fracture.

Many training institutions in low-income countries do not have the resources to purchase and maintain a clinical-grade endoscopy tower dedicated to the laboratory. This project aimed to create a low-cost endoscope camera system using online-sourced materials to allow the operators to practice endoscopic surgical techniques in a cadaver laboratory setting. ⋯ This article demonstrated how to produce a low-cost endoscope camera system for laboratory training in neuroendoscopy.

Vestibular schwannomas are a multifaceted group of tumors that can present with different sizes and involvement of critical neurovascular structures.1-6 While operating on these tumors, a critical goal is postoperative preservation of facial nerve function and hearing. We present the case of a 66-year-old male with a history of severe left-sided tinnitus and progressive hearing loss (Video 1). Preoperative imaging depicted a lesion highly suggestive of an intracanalicular vestibular schwannoma. ⋯ Postoperative imaging demonstrated complete tumor resection. The patient's symptoms improve, and there were no new neurologic deficits on follow-up.
