Dystonia in pantothenate kinase-associated neurodegeneration (PKAN) is progressive despite medication. Deep brain stimulation (DBS) was reported to effectively provide symptom relief. No consensus exists in candidate and target selection for DBS. We aimed to demonstrate effectiveness of subthalamic DBS (STN-DBS) placement in pediatric patients with PKAN. ⋯ This case series demonstrated that STN-DBS is an effective symptom-based treatment for pediatric patients with PKAN.

Neurosurgeons have a rich history of involvement in medical student education. We review the scope of related published works with the goal of highlighting recently increased efforts to innovate in neurosurgical education and discuss where future efforts must go. A scoping review was performed after comprehensive search of PubMed MEDLINE and Embase databases. ⋯ Despite increasing need for neurosurgical education in medical school, available experiences in formal curricula are diminishing. Longitudinal exposure to neurosurgery throughout medical school will help ensure a foundational understanding of neurosurgical disease management for all physicians and provide a pathway of exploration, education, and mentorship for the most suitable candidates. Neurosurgery faculty mentorship is particularly important to ensure that the next generation of neurologic surgeons is well equipped to treat patients, catalyze innovative research, and espouse both diverse perspectives and novel ideas.

Minimally invasive spinal surgery (MISS) techniques offer several beneficial prospects and are being increasingly requested by patients. However, these techniques have not been uniformly adopted by spinal surgeons, and they remain controversial among some. Several barriers have prevented widespread adoption of MISS. ⋯ This requires surgeons to not only acquire the new and specialized MISS skillset but also maintain their ability to perform open surgery. These factors present challenges common to developing and innovative surgical techniques. Here, we review the barriers preventing wider adoption of MISS and present a framework to promote the safe and effective growth of MISS.

Although cervical disc arthroplasty (CDA) has reportedly been associated with similarly low incidences of complications to anterior cervical discectomy and fusion, the phenomenon of anterior bone loss (ABL) is unique to CDA and has only recently gained notice. This study thus aimed to investigate the incidence of ABL and its correlation with cervical alignment post-operation. ⋯ During the mean follow-up of 2 years, ABL was a common radiologic finding. More than half of the patients (26 of 41, 63.4%) in the series gained cervical lordosis (ΔCobb >0) after CDA. These patients with increased cervical lordosis (ΔCobb >0) after CDA had higher grades of ABL.

C1/2 cervical pedicle screw fixation is a well-known procedure for treating severely damaged and unstable C1/2 fractures. On the other hand, C1/C2 screw fixation is not safe and can lead to potentially disastrous consequences. The importance of personalized 3-dimensional (3D) printed navigational guides in avoiding these consequences cannot be overstated. ⋯ In this preclinical study, we demonstrated that it is possible to create patient-specific pedicle drill guides using open-source editing software and a commercially available desktop polylactic acid printer, resulting in high accuracy rates in pedicle screw placement in C1/2 patient models.
