Review Case Reports
Long-Term Outcome of Spinal Extranodal Rosai Dorfman Disease: a Report of Two Cases and Systematic Review.
Rosai-Dorfman disease (RDD) is a rare pathologic entity caused by sinus histiocytosis with massive cervical lymphadenopathy. Isolated spinal involvement is an infrequent presentation of extranodal RDD. The clinical and radiologic appearance of RDD represents a diagnostic challenge. We report 2 patients with paraparesis caused by RDD of the thoracic spine and a PRISMA-style systematic review. ⋯ RDD is a rare occurrence and should be considered in the differential diagnosis of extradural or intradural spinal lesions. Gross total resection is recommended, and long-term clinical follow-up with MRI is advised. Residual or recurrent RDD requires steroids or radiation therapy.

Although O-arm-based navigation (ON) has been considered a better choice than the conventional freehand (FH) technique for spine surgery, clinical evidence showing the accuracy of ON compared with the FH technique is limited. The purpose of this study was to evaluate the accuracy of pedicle screw insertion under ON compared with the FH technique. ⋯ Compared with conventional methods, navigation provides greater accuracy in the placement of pedicle screws, accelerates the insertion, and reduces the complications associated with screw insertion. However, it may increase exposure time to radiation, which may harm the patient's or surgeon's health.

Review Biography Historical Article
Staged Cranial Surgery for Intracranial Lesions: A Historical Perspective.
We follow the development of staged resection from its first description by Walter E. Dandy, one of the founding fathers of neurosurgery, in 1925 in which he removed a large vestibular schwannoma. This historical vignette cites neurosurgical case reports and literature to demonstrate the evolution of staged resection of intracranial lesions, from Dandy's initial use to its becoming a more viable and safe option for the treatment of meningiomas, vestibular schwannomas, and skull base lesions (among numerous other intracranial pathologies). We also discuss the current advancements and future perspectives of staged resection that may show promise in effectively treating a wide range of pathologies while simultaneously reducing morbidity rates-a warrant for further exploration of staged cranial surgery as an important tool in neurosurgery.

Randomized Controlled Trial Comparative Study
Comparison of Clinical and Radiologic Outcome Between Mini-Open Wiltse Approach and Fluoroscopic-Guided Percutaneous Pedicle Screw Placement: A Randomized Controlled Trial.
To compare clinical efficacy, radiographic outcome, and radiation exposure between mini-open pedicle screw (MPS) fixation with the Wiltse approach and percutaneous pedicle screw (PPS) fixation in treatment of young and middle-aged patients with thoracolumbar burst fractures. ⋯ Both MPS fixation with the Wiltse approach and PPS fixation are safe and effective in the treatment of single-segment thoracolumbar vertebral fractures. Nevertheless, considering the surgical duration, radiation exposure, facet joint violation, vertebral body height, and vertebral body angle at the last follow-up, MPS fixation with the Wiltse approach is a better choice than PPS.
