Pars Interarticularis Fractures Treated with Minimally Invasive Surgery: A Literature Review.

Recurrent stress on the isthmic pars interarticularis often leads to profound injury and symptom burden. When conservative and medical management fail, there are various operative interventions that can be used. The current review details the common clinical presentation and treatment of pars injury, with a special focus on the emerging minimally invasive procedures used in isthmic pars interarticularis repair. PubMed and Google Scholar database literature reviews were conducted. The keywords and phrases that were searched include but were not limited to; "history of spondylolysis", "pars interarticularis", "pars defect", "conventional surgical repair of pars", and "minimally invasive repair of pars". The natural history, conventional presentation, etiology, risk factors, and management of pars interarticularis injury are discussed by the authors. The surgical interventions described include the Buck's repair, Morscher Screw-Hook repair, Scott's Wiring technique, and additional pedicle screw-based repairs. Minimally invasive techniques are also reviewed, including the Levi technique. Surgical intervention has been proven to be safe and effective in managing pars interarticularis fractures. However, minimally invasive techniques often provide additional benefit to patients such as reducing damage of surrounding structures, decreasing postoperative pain, and limiting the time away from sports and other activities.

Neurosurgery Influences and X: A Social Media Analysis.

BACKGROUND: There exists a complex and ever-evolving relationship between social media and medicine. This study investigates the usage of X (formerly Twitter) among neurosurgeons and explores how virtual engagement potentially impacts this specialty. METHODS: The researchers examined X posts from the top fifty influential neurosurgeons over 6 months. Demographics and practice information were collected. Posts were categorized into 9 predetermined coding definitions. Descriptive statistics were used to summarize user characteristics. χ2 tests and two-tailed T-tests were employed to examine patterns of posting behavior. RESULTS: Most influencers practiced in an academic setting (89%) and 43% of them were age fifty or older. Only 15% identified as female. Cerebrovascular subspecialists accounted for 39% of the cohort. Reposting was the most popular type of posting, constituting 61% of all posts. The most common postcategory observed was "Professional Events" (31%), while "Patient Education" was the least common (0.8%). Private practice and general neurosurgeons infrequently posted about "Professional Events" (5.1%, P < 0.01 and 3.2%, P < 0.01, respectively). "Personal Thoughts" constituted the second most common category, with a notable increase among users younger than 50 (25%, P < 0.01), individuals who identified as female (62%, P < 0.01), those in private practice (69%, P < 0.01), and general neurosurgeons (86%, P < 0.01). CONCLUSIONS: Neurosurgeons of all ages use X to advance their careers and stay updated. However, the utilization of this influential platform likely varies depending on the current practice setting and individual career goals. Neurosurgeons on X appear to have the greatest influence within an academic context, particularly when promoting professional events.

The role of limited access to students from more diverse nonfeeder medical schools in creating diversity inequities in neurosurgical residency.

OBJECTIVE: Improving racial/ethnic diversity in neurosurgery is a long-standing issue that needs to be addressed. The positive correlation between medical students with home neurosurgery programs and successful matriculation into neurosurgical residency is well documented. In this article, the authors explored the relationship between decreased racial/ethnic diversity in neurosurgery residency programs and racial/ethnic diversity in feeder medical schools. METHODS: The authors conducted a standardized review of the literature to evaluate potential causes for decreased racial/ethnic diversity within neurosurgery. Additionally, they calculated the average enrollment of Black/African American medical students at the top 5 neurosurgery feeder medical schools (determined by Antar et al. following the 2014-2020 match cycles) during the 2021-2022 school year and compared that with the enrollment at US allopathic medical schools with the highest enrollment of Black/African American students. They also compared these two groups in terms of how many students they sent into neurosurgery residency programs from 2014 to 2020. For each of these comparisons, the authors conducted a two-sample t-test to evaluate correlation between these two variables. RESULTS: There was significantly lower average enrollment of Black/African American students at the top 5 feeder medical programs into neurosurgery residency (80.6 ± 8.32) compared with the top 5 medical schools with Black/African American enrollment in the 2021-2022 school year (279 ± 122.00, p < 0.05). The authors also found a significant increase in the number of students entering neurosurgery residency programs between the top 5 feeder medical programs into neurosurgery residency (30.8 ± 6.06) and the top 5 medical programs for Black/African American enrollment (6 ± 6.16, p < 0.0001). CONCLUSIONS: In this paper, the authors examined, through a Black/African American lens, the role of racial/ethnic diversity in medical schools that historically send many students to neurosurgery residency. This study sought to provide insight into this problem and examine how Black/African American students from nonfeeder medical schools are disproportionately affected. The authors' findings suggest that the lack of Black/African American representation in neurosurgery is strongly correlated with the diversity efforts of medical schools. Lastly, the authors highlight the University of Miami's Summer Research Scholarship in Neurosurgery for Medical Students and other programs as potential solutions to combat the lack of racial/ethnic diversity in neurosurgery.

Analysis of severity in ischemic stroke patients with coronary artery disease in the telestroke network.

Aim: This study investigated demographic and clinical risk factors associated with severity in acute ischemic stroke (AIS) patients with a history of coronary artery disease (CAD). Materials & methods: Multivariate logistic regression models were used to determine specific factors associated with worsening or improving neurologic functions among AIS patients with CAD treated in the telestroke. Results: AIS patients with CAD, peripheral vascular disease (OR: 3.995; 95% CI: 1.035-15.413; p = 0.044) and hypertension (OR: 6.056; 95% CI: 1.207-30.374; p = 0.029) were associated with worsening neurologic functions. Conclusion: Our findings suggest the need to develop strategic management to improve the care of AIS patients with a history of CAD that present with hypertension and peripheral vascular disease in the telestroke network.

This study investigated risk factors that contribute to poor outcomes in stroke patients with a history of coronary artery disease. We used advanced statistical approach to identify risk that contribute to poor neurologic functions. We observed that peripheral vascular disease and hypertension were associated with worsening neurologic functions. Our findings suggest the need to develop management plans to improve the care of acute ischemic stroke patients with a history of coronary artery disease that present with hypertension and peripheral vascular disease in the telestroke network.

Stroke Severity among Men and Women Acute Ischemic Stroke Patients in the Telestroke Network.

INTRODUCTION: This study investigates gender differences among stroke patients treated in the telestroke network using specific risk factors that contribute to stroke severity. METHODS: We examined gender differences in stroke severity among 454 patients hospitalized with acute ischemic stroke (AIS). The logistic regression model was used to predict clinical risk factors associated with stroke severity in men and women AIS patients. RESULTS: In the adjusted analysis among women patients, increasing age (odds ratio [OR] = 1.05, 95% CI: 1.017-1.085, p = 0.003) and higher heart rate (OR = 1.031, 95% CI: 1.005-1.058, p = 0.021) were associated with worsening neurological functions, while direct admission (OR = 0.191, 95% CI: 0.079-0.465, p < 0.001) was associated with improving neurologic functions. Among men, hypertension (OR = 3.077, 95% CI: 1.060-8.931, p = 0.039) and higher international normalized ratio (INR) (OR = 21.959, 95% CI: 1.489-323.912, p = 0.024) were associated with worsening neurologic functions, while Caucasian (OR = 0.181, 95% CI: 0.062-0.526, p = 0.002) and obesity (OR = 0.449, 95% CI: 0.203-0.99, p = 0.047) were associated with neurologic improvement. CONCLUSION: Increasing age and heart rate in women, hypertension and greater INR in men contribute to worsening neurologic functions. There is a need to develop strategies to improve the care of both men and women in the telestroke network.
