Gamma Knife Radiosurgery for Hypothalamic Hamartoma: A Multi-Institutional Retrospective Study on Safety, Efficacy, and Complication Profile.
Gamma knife radiosurgery (GKRS) is a safe and effective treatment option for hypothalamic hamartomas (HH), but there is no consensus opinion on its timing, dosage, and follow-up. The aim of this study was to define the safety, efficacy, outcome, and complication profile of GKRS in this patient population. ⋯ GKRS is a safe and effective modality for treatment of HH with significant improvement in seizure control with minimal disruption of endocrine profile. It provides an excellent safety, efficacy, and complication profile, especially for small HH. Latency of results and its adjuvant nature remain the areas of research and breakthroughs among contemporary treatment options.

Consensus guidelines do not exist to guide the role of stereotactic radiosurgery (SRS) in the management of patients with Spetzler-Martin Grade III-V arteriovenous malformations (AVMs). We sought to establish SRS practice guidelines for Grade III-V AVMs based on a critical systematic review of the published literature. ⋯ Most patients with Spetzler-Martin Grade III AVMs have favorable SRS treatment outcomes; however, the obliteration rate for Grade IV-V AVMs is less than 50%. The available studies are heterogenous and lack nuanced, long-term, grade-specific outcomes.

Despite the high morbidity associated with glenohumeral dysplasia (GHD) in children with brachial plexus birth injuries, the progression of this condition often remains unnoticed, even after correcting for the underlying brachial plexus birth injuries. GHD, driven by a multifactorial process involving disruptions in both direct and indirect neural regulation of bony and muscular structures, can lead to intermittent or permanent shoulder mobility imbalances, significantly impacting the quality of life of those affected. Recent research efforts are increasingly directed toward identifying the root causes, managing the deformity, and determining effective treatment options for correcting GHD. ⋯ As research continues to focus on understanding the complexities of this condition, the aim of this review article is to summarize the current literature on the course of brachial plexus birth injury and the development of GHD. By doing so, we hope to provide neurosurgeons with the necessary knowledge and essential tools needed to identify and effectively treat GHD during management of brachial plexus birth injuries.

Significant evidence has indicated that the reporting quality of novel predictive models is poor because of confounding by small data sets, inappropriate statistical analyses, and a lack of validation and reproducibility. The Transparent Reporting of a multivariable prediction model for Individual Prognosis or Diagnosis (TRIPOD) statement was developed to increase the generalizability of predictive models. This study evaluated the quality of predictive models reported in neurosurgical literature through their compliance with the TRIPOD guidelines. ⋯ Published predictive models in neurosurgery commonly fall short of meeting the established guidelines laid out by TRIPOD for optimal development, validation, and reporting. This lack of compliance may represent the minor extent to which these models have been subjected to external validation or adopted into routine clinical practice in neurosurgery.

In recent years, there has been an outpouring of scoring systems that were built to predict outcomes after various surgical procedures; however, research validating these studies in spinal surgery is quite limited. In this study, we evaluated the predictability of the American College of Surgeons National Surgical Quality Improvement Program Surgical Risk Calculator (ACS NSQIP SRC) for various postoperative outcomes after spinal deformity surgery. ⋯ The ACS NSQIP SRC is a poor predictor of outcomes after spinal deformity surgery.
