Atlantoaxial subluxation in the pediatric patient: Case series and literature review

Objective: Atlantoaxial subluxation (AAS) occurs when there is misalignment of the atlantoaxial joint. Several etiologies confer increased risk of AAS in children, including neck trauma, inflammation, infection, or inherent ligamentous laxity of the cervical spine. Methods: A single-center, retrospective case review was performed. Thirty-four patients with an ICD-10 diagnosis of S13.1 were identified. Demographics and clinical data were reviewed for etiology, imaging techniques, treatment, and clinical outcome. Results: Out of thirty-four patients, twenty-two suffered cervical spine trauma, seven presented with Grisel’s Syndrome, four presented with ligamentous laxity, and one had an unrecognizable etiology. Most diagnoses of cervical spine subluxation and/or instability were detected on computerized tomography (CT), while radiography and magnetic resonance imaging (MRI) were largely performed for follow-up monitoring. Six patients underwent cervical spine fusion, five had halo traction, twelve wore a hard and/or soft collar without having surgery or halo traction, and eight were referred to physical therapy without other interventions. Conclusion: Pediatric patients with atlantoaxial subluxation may benefit from limited 3D CT scans of the upper cervical spine for accurate diagnosis. Conservative treatment with hard cervical collar and immobilization after reduction may be attempted, but halo traction and halo vest immobilization may be necessary. If non-operative treatment fails, cervical spine internal reduction and fixation may be necessary to maintain normal C1-C2 alignment

In reply: congress of neurological surgeons systematic review and evidence-based guidelines on the treatment of pediatric hydrocephalus: update of the 2014 guidelines

We appreciate the thoughtful critique1 of our recent publication “Congress of Neurological Surgeons Systematic Review and Evidence-Based Guidelines on the Treatment of Pediatric Hydrocephalus: Update of the 2014 Guidelines.”2 We must emphasize that our process used a rigorous methodology to update answers to questions asked in the original 2014 guidelines. 3 One question in our original publication regarded the use of antibiotic-impregnated shunts (AISs) in children with hydrocephalus. For this question, we evaluated whether AIS reduced the risk of infection compared to standard shunts. In our update, we found level I evidence that supported our finding, based on the British antibiotic and silver-impregnated catheters for ventriculoperitoneal shunts (BASICS) of AISs.4 In our posed PICO (population, intervention, control, and outcomes) question, we did not evaluate long-term function or mechanical failure related to AIS. The hypothesis that mechanical failure may be caused by masked AIS infections has yet to be proven with published medical evidence. In addition, while the Fragility Index (FI) of the BASICS study may be low, the study was still statistically significant and adequately powered to answer this question

Telehealth in Neurosurgery: 2021 Council of State Neurosurgical Societies National Survey Results

OBJECTIVE: Telehealth was rapidly adopted during the COVID-19 pandemic. A survey was distributed to neurosurgeons in the United States (US) to understand its use within neurosurgery, what barriers exist, unique issues related to neurosurgery, and opportunities for improvement. METHODS: A survey was distributed via email and used the SurveyMonkey platform. The survey was sent to 3,828 practicing neurosurgeons within the US 404 responses were collected between Oct. 30, 2021, through Dec. 4, 2021. RESULTS: During the pandemic, telehealth was used multiple times per week by 60.65% and used daily by an additional 12.78% of respondents. A supermajority (89.84%) of respondents felt that evaluating patients across state lines with telemedicine is beneficial. Most respondents (95.81%) believed that telehealth improves patient access to care. The major criticism of telehealth was the inability to perform a neurological exam. CONCLUSIONS: Telehealth has been widely implemented within the field of neurosurgery during the COVID-19 pandemic and has increased access to care. It has allowed patients to be evaluated remotely, including across state lines. While certain aspects of the neurological exam are suited for video evaluation, sensation and reflexes cannot be adequately assessed. Neurosurgeons believe that telehealth adds value to their ability to deliver care

ACR Appropriateness Criteria Head Trauma—Child

Head trauma is a frequent indication for cranial imaging in children. CT is considered the first line of study for suspected intracranial injury because of its wide availability and rapid detection of acute hemorrhage. However, the majority of childhood head injuries occur without neurologic complications, and particular consideration should be given to the greater risks of ionizing radiation in young patients in the decision to use CT for those with mild head trauma. MRI can detect traumatic complications without radiation, but often requires sedation in children, owing to the examination length and motion sensitivity, which limits rapid assessment and exposes the patient to potential anesthesia risks. MRI may be helpful in patients with suspected nonaccidental trauma, with which axonal shear injury and ischemia are more common and documentation is critical, as well as in those whose clinical status is discordant with CT findings. Advanced techniques, such as diffusion tensor imaging, may identify changes occult by standard imaging, but data are currently insufficient to support routine clinical use. The ACR Appropriateness Criteria are evidence-based guidelines for specific clinical conditions that are reviewed every 3 years by a multidisciplinary expert panel. The guideline development and review include an extensive analysis of current medical literature from peer-reviewed journals and the application of a well-established consensus methodology (modified Delphi) to rate the appropriateness of imaging and treatment procedures by the panel. In those instances in which evidence is lacking or not definitive, expert opinion may be used to recommend imaging or treatment
