Middle meningeal artery (MMA) embolization has recently emerged as a treatment option for chronic subdural hematoma (cSDH). It is considered a simple and potentially safe endovascular procedure. ⋯ Both onyx and PVA as embolic agents for cSDH can be used safely and have comparable clinical and surgical outcomes.

Recent studies suggest that socioeconomic status (SES) influences outcomes after spinal fusion. The influence of SES on postoperative outcomes is increasingly relevant as rates of lumbar fusion rise. ⋯ Black race, less than 12th grade education, <$25K net worth, and lack of homeownership were associated with poorer postoperative outcomes and increased costs. Increasing perioperative support for patients with these sociodemographic risk factors may improve postoperative outcomes.

As the clinical applications of neurologically implanted devices increase, so do opportunities for intracranial investigations in human patients. In some of these studies, patients participate in research during their awake brain surgery, performing additional tasks without the prospect of personal therapeutic benefit. These intraoperative studies raise persistent ethical challenges because they are conducted during a clinical intervention, in a clinical space, and often by the treating clinician. ⋯ The second is relational: Many practices do not fully consider the effects of trust between patient-participants and surgeon-researchers. In exploring these concerns, we also raise questions about whether additional steps beyond preoperative consent may improve the process because decisions at this time are decoupled from both the experiences and vulnerability of awake brain surgery. Motivated by these considerations, we propose 2 practices: first, requiring a third-party patient advocate in initial consent and second, requiring verbal intraoperative reconsent before initiating research.

Bilateral pallidal deep brain stimulation (DBS) has been broadly accepted as a feasible surgical procedure for treating various forms of dystonia, but its effects on motor function, neuropsychological status, and mood in patients with Meige syndrome have rarely been examined. ⋯ Bilateral GPi-DBS is a safe and effective approach for medically refractory Meige syndrome that can improve motor function and quality of life without cognitive and mood side effects.

Proximal junctional kyphosis (PJK) and proximal junctional failure (PJF) can be catastrophic complications associated with adult spinal deformity (ASD) surgery. These complications are markedly influenced by osteoporosis, leading to additional vertebral fracture and pedicle screw loosening. The MRI-based vertebral bone quality score (VBQ) is a newly developed tool that can be used to assess bone quality. ⋯ In patients undergoing ASD correction, higher VBQ was independently associated with PJK/PJF occurrence. Measurement of VBQ score on preoperative MRI may be a useful adjunct to ASD surgery planning.
