Stereotactic radiosurgery (SRS) is effective for patients with medically refractory trigeminal neuralgia with a 75%-90% response rate. Consideration of the integral dose (ID) to the target nerve within the 50% isodose line was reported to help select prescription doses to maximize effectiveness and minimize bothersome numbness. The objective of this study was to externally validate the ID as a predictor of outcomes after SRS. ⋯ The ID did not predict recurrence-free survival or sensory dysfunction. Our observations suggest improved nerve coverage by the most powerful area of the isocenter, for instance, by targeting a narrower segment if feasible, could result in more durable pain relief. Further studies to validate these findings are needed.

Retrospective Review. ⋯ Patients undergoing lumbar fusion with greater than 2 years of symptoms prior to surgery have a smaller increase in PROMIS-PF and are less likely to achieve MCID on PROMIS-PF. Further study is needed in order to determine the optimal timing for lumbar fusion surgery following symptom onset.

United States neurological surgery residency education has undergone substantive changes over the past 2 decades. Neurosurgical professional bodies have developed numerous initiatives providing standardized assessments and training opportunities for residency programs. However, there have been few studies using standardized measures to assess core components of educational programming in individual programs. ⋯ Accounting for the practice effect revealed a significant interaction effect between the number of attempts taking the ABNS examination and whether formal didactics were taught, accounting for 46.2 points on the examination (t = 2.309, P = .023); however, REH alone did not have a significant effect on the scaled scores (t = -1.649, P = .102). ABNS written board scores represent a standardized metric by which educational initiatives within training programs may be assessed for efficacy. Further research is needed to identify educational approaches that are effective to meet the goal of demonstrated mastery of fundamental knowledge in neurosurgery across a diversity of neurological surgery residency programs.

Retrospective cohort study. ⋯ Relative to two-level ACDF patients, two-level CDA patients were found to have significantly lower odds of 90-day readmissions and minor adverse events (dysphagia), while rates of major adverse events (pulmonary embolism, deep vein thrombosis, sepsis, etc.) were comparable between the groups. Further CDA patients had lower cost of overall care, but no difference in five-year survival to cervical spine reoperation. Thus, it may be appropriate to further consider CDA when two-level surgery is pursued.
