Atlas assimilation (AA) may be associated with atlantoaxial dislocation, Chiari malformation (CM), and basilar invagination. The importance of AA in the context of craniocervical junction (CVJ) anomalies is unclear. Considering this context, this study's objective is to discuss the role of AA in the management of CVJ anomalies, especially in CM. ⋯ Dynamic examinations may provide additional evidence of atlantoaxial instability. Although AA per se is not considered an unstable configuration, further and detailed evaluations of patients with CM associated with AA are necessary. Some associated unstable configurations required concomitant CVJ fixation.

Comparative Study
Comparison of hybrid constructs pedicle screws with sublaminar polyester bands versus pedicle screws only treatment of neuromuscular scoliosis.
The choice of implants in neuromuscular scoliosis (NMS) surgery remains controversial. Sublaminar polyester bands (SPBs) seem to be a promising alternative implant. The purpose of current study was to compare clinical and radiologic results of posterior instrumentation and fusion using hybrid constructs versus only pedicle screws for NMS treatment. ⋯ SPBs might be a better fixation alternative at the apex of rigid spinal deformity in NMS. The deformity can be corrected with less blood loss and at a similar rate of correction, with similar rate complications compared with pedicle screws.

Participation in the health care and government advocacy arena may represent new and challenging perspectives for the traditional neurosurgeon. However, those with a strong understanding of the laws, rules, regulations, and fiscal allocation process can directly influence the practice of neurosurgery in the United States. We seek to shine light on the black box of how health care laws are passed, the influence and techniques of lobbying, and the role and rules surrounding political action committees. This practical review of health care advocacy is supplemented by a blueprint for engagement in the political arena for the practicing neurosurgeon.

The Mayfield skull clamp is the most commonly used 3-pin head immobilization device. It is routinely used in cranial neurosurgical procedures and selected cervical procedures. Despite its role in some serious complications, guidelines and nuances on the correct application of the Mayfield clamp are lacking. The goal of this article was to present an overview of the complications associated with the Mayfield skull clamp. We also present a conceptual framework of the correct use-in our opinion-of the Mayfield clamp in several standard approaches to avoid the most common complications. ⋯ Attention to detail, anatomy, and the primum non nocere principle are imperative in every step of the neurosurgical pathway, including placement of the Mayfield skull clamp. Thoughtful application, taking into consideration several nuances, is recommended to avoid inadvertent patient harm.

The impact of the coronavirus disease 2019 (COVID-19) pandemic has led to a significant transformation in medical practice and training. This nationwide survey study aims to evaluate the 1-year impact of the pandemic on training of neurosurgical residents. ⋯ COVID-19 has had a significant impact on neurosurgical practice and training. Effective measures should be used to mitigate these effects and better prepare for the future challenges.
