Unilateral biportal endoscopic (UBE) spine surgery for spinal diseases has been increasing in popularity because of its favorable outcomes. The goal of this systemic review is to analyze the status of outcomes and complications in lumbar disc herniation during UBE discectomy. ⋯ Even with the small number of studies and reports analyzed, biases were the main limitation of this analysis; overall, the clinical outcomes and complication rates associated with UBE discectomy were relatively good. It is clear that UBE discectomy is a good treatment choice for lumbar disc herniation, but to prevent unique UBE surgery complications, a clear understanding of the surgical procedures and careful efforts to overcome the learning curve are necessary.

Cerebral infarction is a major contributor to poor outcome in patients with aneurysmal subarachnoid hemorrhage (aSAH). Timing of treatment has been discussed as a possible contributor. We aimed to analyze the impact of treatment timing on the risk of cerebral infarction and poor outcome after aSAH. ⋯ Our data confirm a considerable risk of cerebral infarction and poor outcome in cases of aneurysm treatment between day 4 and 14 after aSAH. A more intense surveillance and prophylactic treatment of cerebral vasospasm might be necessary in cases of aneurysm treatment in the vasospasm phase.

Despite lack of nationwide Medicare coverage by the Centers for Medicare and Medicaid Services, the utilization of cervical disc arthroplasty (CDA) has risen in popularity. The purpose was to compare primary and revision CDA from 2010 to 2020 with respect to: (1) utilization trends, (2) patient demographics, and (3) health care reimbursements. ⋯ There is a high rate of annual growth in CDA utilization and revision CDA in the United States. Reimbursements for revision CDA were more than double primary cases.

Biportal endoscopic spine surgery is gaining popularity in managing degenerative lumbar diseases and has optimal indications and contraindications. The perioperative complications related to the biportal endoscopic approach affect the postoperative outcomes. Therefore, this study aimed to review the indications, contraindications, and complications of biportal endoscopic decompression for lumbar stenosis. ⋯ Favorable indications for a biportal endoscopic approach are central lumbar, lateral recess, foraminal, extraforaminal stenoses, and the Bertolotti syndrome. Incidental durotomy and postoperative epidural hematomas are common complications of biportal endoscopic decompression.

Klinger's fiber dissection technique is widely used for studying the anatomy of white matter. Herein, we present a technical description of Klinger's proposed fiber dissection algorithm with neuronavigation assistance which allows for a more accurate determination of the projection of association fibers. ⋯ Electromagnetic navigation is an accurate and useful technique. It allows the researcher the ability to virtually project the association fibers and their cortico-cortical terminations to the surface of the brain, even at the final stages of dissection when the superficial structures are removed. To obtain accurate targeting, it is important to use the appropriate neuronavigation protocol.
