Mechanical failure (MF) is a serious burden for patients with adult spinal deformity (ASD) who have undergone deformity correction surgery. Surgeons have sought to understand the mechanism and prevent this problematic complication, but this goal remains to be achieved. The gravity line (GL) of the whole body is a noteworthy parameter that represents global sagittal balance, for which normative values for the axial skeleton have been studied. ⋯ Postoperative GL-HA offset is a substantial risk factor for MF after ASD surgery. Surgical correction of ASD with a GL-HA offset greater than 5 cm is significantly related to MF. The GL should be located near the HA after ASD surgery.

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.

In the present article, the impact of the COVID-19 pandemic on geographical trends in the neurosurgery match in successfully matched applicants was analyzed. A cross-sectional analysis for the years from 2017 to 2021 was performed. Successful applicants' region, state, and medical school were compared with the location of their matched residency program. ⋯ The COVID-19 pandemic did not significantly affect geographic trends during the neurosurgery match in 2021. This is of note as the COVID-19 pandemic significantly affected the match in other competitive specialties, including plastic surgery, dermatology, and otolaryngology. Despite limited away rotations, it is possible that neurosurgery programs did not change their applicant selection criteria and implemented systems to virtually interact with applicants outside of their local region.

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.

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.
