The performance of transforaminal endoscopic lumbar interbody fusion through a Kambin's triangle approach requires significant modifications when compared to a traditional transforaminal discectomy. Indeed, due to the inherently limited field of view, small working corridor, and need to deploy an adequately sized interbody graft, there are several important technical adaptations which can help improve the efficacy of this approach. In this manuscript, the technical aspects of a percutaneous, endoscopic interbody fusion are discussed in detail.

Review Case Reports
Unstable Hangman Fracture Complicated by Vertebral-Venous Fistula: Surgical Considerations and Review of Literature.
Hangman fracture or traumatic spondylolisthesis of the axis associated with a traumatic vertebral venous fistula (VVF) is a rare entity and sparsely reported in literature. Standard recommendations for management of such rare and complex scenarios are not available and hence the strategy has to be individualized on a case-by-case basis. ⋯ This case report emphasizes the need for timely recognition and management of a VVF, which can rarely coexist with hangman fracture, and discusses the interesting surgical paradigms in the management. We also present a review of literature.

The rare clinical entity of primary posterior pituitary tumors (PPTs) includes pituicytomas, granular cell tumors, spine cell oncocytomas, and sellar ependymomas. The recent World Health Organization classification of PPTs based on thyroid transcription factor 1 positivity has led to more investigations into the epidemiology, clinical presentation, nature history, histologic features, and operative characteristics of these tumors. The aim of this review is to summarize the characteristics of primary PPTs. ⋯ Primary PPTs are a rare group of pituicyte-derived low-grade nonneuroendocrine neoplasms that arise from the sellar region. The nondescript radiographic findings and subtle endocrine abnormalities also veil their accurate diagnostic prediction. As shown through the narrative as well as the literature review, there is still a lot to be understood about PPTs. A prospective multicenter registry of these rare tumors would benefit both the neurosurgical as well as the endocrinologic knowledge base.

Review Historical Article
Trepanation of the Outer Table as a Treatment for Scalping Injuries: Historical Perspective and Modern Applications.
Complex cranial wounds represent complex surgical problems. In modern times, these are mostly due to accidental trauma. During the period of the American Frontier, violent scalping was a common practice. ⋯ This was accomplished as a byproduct of the violence of the scalping or as an application of the technique first described by Augustin Belloste in 1696. Application of this technique in a modern setting may allow for improved wound healing. Trepanation of the outer table to aid in healing and closure of complex cranial wounds has a long history of successful practice and can be successfully applied to modern practice.

Multicenter Study Comparative Study
Comparative analysis of the Pipeline and the Derivo flowdiverters for the treatment of unruptured intracranial aneurysms - a multicentric study.
Flow diversion represents a safe and efficient technique for the endovascular treatment of complex intracranial aneurysms. This study compares 2 competing flow diverters, the Pipeline embolization device (PED) and the Derivo Embolization Device (DED) regarding technical aspects, clinical outcome, and angiographic results. ⋯ In regard to complication rates, functional outcome, and aneurysm occlusion, no significant differences were found between the PED and DED collective.
