To compare outcomes of proton radiation therapy (PRT), stereotactic radiosurgery (SRS), and x-ray-based radiation with an SRS boost (XRT + SRS) for newly diagnosed clival chordoma. ⋯ Patients after subtotal resection or biopsy may benefit from the incorporation of SRS.

Percutaneous cement discoplasty (PCD) was introduced to treat symptomatic vertical instability of the lumbar spine in a minimally invasive way. The aim of the present study was to analyze the complication pattern after PCD and to identify factors that predict the chance of cement leakage, reoperation, and length of hospital stay (LOS). ⋯ PCD is a relatively safe and effective procedure for treating spinal instability caused by advanced-stage disc degeneration characterized by vacuum phenomenon. Cement leakage is not uncommon but is only a radiologic complication without clinical consequences in most cases. On the other hand, it can increase the LOS and is a significant risk factor for reoperation.

Cerebral arterial fenestrations are anatomic variants of undetermined significance where there is a division of a single vessel into at least 2 channels, each having endothelial and muscular layers, that coalesce to a single lumen in the distal course of the vessel. The basilar artery is the most common site, followed by the anterior communicating artery. ⋯ However, simultaneous existence of all 3 anomalies in a single individual has never been reported. Here we present a case of medial sphenoid wing meningioma with these incidental findings during workup and further delineation of anatomy following surgical resection of meningioma.

The role of self-citation has not been discussed in the neurosurgery literature, although citations, citation indices, and impact of research may enhance funding opportunities, academic positions, fellowship opportunities, employment, and professional identity development. We sought to assess the magnitude and role of self-citation in academic neurosurgery. ⋯ Academic neurosurgeons must understand the ecosystem around self-citation. In our study, we found overall low levels of self-citations in neurosurgery journals with a few outliers. We have, however, noticed an increasing trend in self-citation rates. Self-citation rates should be considered while evaluating the impact of an author and research productivity. Contrary to popular belief, self-citation is not always unethical and must be understood within its circumstances.

This study aimed to compare the postoperative alignment of static and expandable cages in lateral single-position (LSP) for indirect decompression in lateral lumbar interbody fusion (LLIF). ⋯ In LSP-LLIF without facet joint resection or other posterior techniques, static and expandable cages showed comparable effectiveness in achieving increased DH, SL, FA, and indirect decompression.
