A systematic review of the power of standardization in pediatric neurosurgery.

In the current neurosurgical field, there is a constant emphasis on providing the best care with the most value. Such work requires the constant optimization of not only surgical but also perioperative services. Recent work has demonstrated the power of standardized techniques in limiting complication while promoting optimal outcomes. In this review article, protocols addressing operative and perioperative care for common pediatric neurosurgical procedures are discussed. These articles address how various institutions have optimized procedures through standardization. Our objective is to improve patient outcomes through the optimization of protocols.

Multidisciplinary neurocutaneous syndrome clinics: a systematic review and institutional experience.

OBJECTIVE: Neurocutaneous syndromes have variable multisystem involvement. The multiorgan involvement, potential pathologies, and various treatment options necessitate collaboration and open discussion to ensure optimal treatment in any given patient. These disorders provide quintessential examples of chronic medical conditions that require a lifelong, multidisciplinary approach. The objectives of this study were to 1) perform a systematic review, thoroughly assessing different multidisciplinary clinic layouts utilized in centers worldwide; and 2) characterize an institutional experience with the management of these conditions, focusing on the patient demographics, clinical presentation, complications, and therapeutic strategies seen in a patient population. METHODS: A systematic review of studies involving multidisciplinary clinics and their reported structure was performed according to PRISMA guidelines using the PubMed database. Then a retrospective chart review of patients enrolled in the Oklahoma Children's Hospital Neurocutaneous Syndromes Clinic was conducted. RESULTS: A search of the PubMed database yielded 251 unique results. Of these, 15 papers were included in the analysis, which identified 16 clinics that treated more than 2000 patients worldwide. The majority of these clinics treated patients with neurofibromatosis (13/16). The remaining clinics treated patients with von Hippel-Lindau syndrome (n = 1), tuberous sclerosis complex (n = 1), and multiple neurocutaneous syndromes (n = 1). The most commonly represented subspecialties in these clinics were genetics (15/16) and neurology (13/16). Five clinics (31%) solely saw pediatric patients, 10 clinics saw a combination of children and adults, and the final clinic had separate pediatric and adult clinics. The retrospective chart review of the Neurocutaneous Syndromes Clinic demonstrated that 164 patients were enrolled and seen in the clinic from April 2013 to December 2021. Diagnoses were made based on clinical findings or results of genetic testing; 115 (70%) had neurofibromatosis type 1, 9 (5.5%) had neurofibromatosis type 2, 35 (21%) had tuberous sclerosis complex, 2 (1%) had von Hippel-Lindau syndrome, 2 (1%) had Gorlin syndrome, and the remaining patient (0.6%) had Aarskog-Scott syndrome. Patient demographics, clinical presentation, complications, and therapeutic strategies are also discussed. CONCLUSIONS: To the best of the authors' knowledge, this is the first detailed description of a comprehensive pediatric neurocutaneous clinic in the US that serves patients with multiple syndromes. There is currently heterogeneity between described multidisciplinary clinic structures and practices. More detailed accounts of clinic compositions and practices along with patient data and outcomes are needed in order to establish the most comprehensive and efficient multidisciplinary approach for neurocutaneous syndromes.

Comparison of anticoagulation and antiplatelet therapy for treatment of blunt cerebrovascular injury in children <10 years of age: a multicenter retrospective cohort study.

PURPOSE: Blunt cerebrovascular injury (BCVI) is uncommon in the pediatric population. Among the management options is medical management consisting of antithrombotic therapy with either antiplatelets or anticoagulation. There is no consensus on whether administration of antiplatelets or anticoagulation is more appropriate for BCVI in children < 10 years of age. Our goal was to compare radiographic and clinical outcomes based on medical treatment modality for BCVI in children < 10 years. METHODS: Clinical and radiographic data were collected retrospectively for children screened for BCVI with computed tomography angiography at 5 academic pediatric trauma centers. RESULTS: Among 651 patients evaluated with computed tomography angiography to screen for BCVI, 17 patients aged less than 10 years were diagnosed with BCVI (7 grade I, 5 grade II, 1 grade III, 4 grade IV) and received anticoagulation or antiplatelet therapy for 18 total injuries: 11 intracranial carotid artery, 4 extracranial carotid artery, and 3 extracranial vertebral artery injuries. Eleven patients were treated with antiplatelets (10 aspirin, 1 clopidogrel) and 6 with anticoagulation (4 unfractionated heparin, 2 low-molecular-weight heparin, 1 transitioned from the former to the latter). There were no complications secondary to treatment. One patient who received anticoagulation died as a result of the traumatic injuries. In aggregate, children treated with antiplatelet therapy demonstrated healing on 52% of follow-up imaging studies versus 25% in the anticoagulation cohort. CONCLUSION: There were no observed differences in the rate of hemorrhagic complications between anticoagulation and antiplatelet therapy for BCVI in children < 10 years, with a nonsignificantly better rate of healing on follow-up imaging in children who underwent antiplatelet therapy; however, the study cohort was small despite including patients from 5 hospitals.

An incidental pure arterial malformation in a child: case report and review of the literature.

PURPOSE: Pure arterial malformations of the brain are rare vascular lesions. METHODS: We present a 10-year-old healthy boy who presented with an incidental finding of pure arterial malformation. RESULTS: Our case seems to represent the second description of pure arterial malformation discovered incidentally in a child. CONCLUSION: We review the clinical presentation, angiographic findings, and management of our case in the context of other reported pediatric cases.

Frontal Occipital and Frontal Temporal Horn Ratios: Comparison and Validation of Head Ultrasound-Derived Indexes With MRI and Ventricular Volumes in Infantile Ventriculomegaly.

OBJECTIVE. The purpose of our study was to assess whether linear ventricular dimensions-specifically, the frontal occipital horn ratio (FOHR) and frontal temporal horn ratio (FTHR) obtained from ultrasound (US)-are reliable measures of ventriculomegaly in infants. Our hypothesis was that these US measures would show good correlation with linear ventricular indexes and ventricular volumes obtained from MRI. MATERIALS AND METHODS. We retrospectively identified 90 infants (age ≤ 6 months corrected gestational age) with ventriculomegaly from 2014 to 2017 who had a total of 100 sets of US and MRI studies performed in a 3-day period. FOHR and FTHR were independently measured on US and MRI by two pediatric radiologists and two pediatric neuroradiologists, respectively. Ventricular and brain volumes were segmented from the MR images, and the ventricle-to-intracranial volume ratio was calculated. MRI served as the reference standard. Intraclass correlation coefficients and Bland-Altman analyses were generated to evaluate interobserver and US-MRI concordance. We assessed correlation of the FOHR and FTHR with the ventricle-to-intracranial volume ratio. RESULTS. Bland-Altman plots of the FOHR and FTHR between US and MRI showed excellent concordance with a bias of 0.05 (95% CI, -0.04 to 0.14) and 0.03 (95% CI, -0.06 to 0.13), respectively. There was good-to-excellent interobserver concordance for FOHR and FTHR on head US or MRI (r = 0.86-0.96). There was good correlation between ventricle-to-intracranial volume ratios and US- and MRI-derived FOHRs and FTHRs (r = 0.79-0.87). CONCLUSION. FOHR and FTHR obtained from US in infants with ventriculomegaly have excellent interobserver concordance, are concordant with MRI-derived linear ratios, and correlate with MRI-derived ventricular volumes. Therefore, US-derived FOHR and FTHR are reliable indexes for clinical follow-up of infantile ventriculomegaly.

Increased complications without neurological benefit are associated with prophylactic spinal cord untethering prior to scoliosis surgery in children with myelomeningocele.

PURPOSE: Children with myelomeningocele (MMC) are at increased risk of developing neuromuscular scoliosis and spinal cord re-tethering (Childs Nerv Syst 12:748-754, 1996; Neurosurg Focus 16:2, 2004; Neurosurg Focus 29:1, 2010). Some centers perform prophylactic untethering on asymptomatic MMC patients prior to scoliosis surgery because of concern that additional traction on the cord may place the patient at greater risk of neurologic deterioration peri-operatively. However, prophylactic untethering may not be justified if it carries increased surgical risks. The purpose of this study was to determine if prophylactic untethering is necessary in asymptomatic children with MMC undergoing scoliosis surgery. METHODS: A multidisciplinary, retrospective cohort study from seven children's hospitals was performed including asymptomatic children with MMC < 21 years old, managed with or without prophylactic untethering prior to scoliosis surgery. Patients were divided into three groups for analysis: (1) untethering at the time of scoliosis surgery (concomitant untethering), (2) untethering within 3 months of scoliosis surgery (prior untethering), and (3) no prophylactic untethering. Baseline data, intra-operative reports, and 90-day post-operative outcomes were analyzed to assess for differences in neurologic outcomes, surgical complications, and overall length of stay. RESULTS: A total of 208 patients were included for analysis (mean age 9.4 years, 52% girls). No patient in any of the groups exhibited worsened motor or sensory function at 90 days post-operatively. However, comparing the prophylactic untethering groups with the group that was not untethered, there was an increased risk of surgical site infection (SSI) (31.3% concomitant, 28.6% prior untethering vs. 12.3% no untethering; p = 0.0104), return to the OR (43.8% concomitant, 23.8% prior untethering vs. 17.4% no untethering; p = 0.0047), need for blood transfusion (51.6% concomitant, 57.1% prior untethering vs. 33.8% no untethering; p = 0.04), and increased mean length of stay (LOS) (13.4 days concomitant, 10.6 days prior untethering vs. 6.8 days no untethering; p < 0.0001). In multivariable logistic regression analysis, prophylactic untethering was independently associated with increased adjusted relative risks of surgical site infection (aRR = 2.65, 95% CI 1.17-5.02), unplanned re-operation (aRR = 2.17, 95% CI 1.02-4.65), and any complication (aRR = 2.25, 95% CI 1.07-4.74). CONCLUSION: In this study, asymptomatic children with myelomeningocele who underwent scoliosis surgery developed no neurologic injuries regardless of prophylactic untethering. However, those who underwent prophylactic untethering were more likely to experience SSIs, return to the OR, need a blood transfusion, and have increased LOS than children not undergoing untethering. Based on these data, prophylactic untethering in asymptomatic MMC patients prior to scoliosis surgery does not provide any neurological benefit and is associated with increased surgical risks.

Children presenting in delayed fashion after minor head trauma with scalp swelling: do they require further workup?

PURPOSE: It is common to evaluate children who have sustained minor head trauma with computed tomography (CT) of the head. Scalp swelling, in particular, has been associated with intracranial injury. A subset of patients, however, present in delayed fashion, often days after the head trauma, as soft tissue edema progresses and their caregiver notices scalp swelling. We explore the value of further workup in this setting. METHODS: We conducted a retrospective review of a prospectively collected cohort of children ≤24 months of age presenting to the Texas Children's Hospital with scalp swelling more than 24 h following a head trauma. Cases were collected over a 2-year study period from June 1, 2014 to May 31, 2016. RESULTS: Seventy-six patients comprising 78 patient encounters were included in our study. The mean age at presentation was 8.8 months (range 3 days-24 months). All patients had noncontrast CT of the head as part of their evaluation by emergency medicine, as well as screening for nonaccidental trauma (NAT) by the Child Protection Team. The most common finding on CT head was a linear/nondisplaced skull fracture (SF) with associated extra-axial hemorrhage (epidural or subdural hematoma), which was found in 31/78 patient encounters (40%). Of all 78 patient encounters, 43 patients (55%) were discharged from the emergency room (ER), 17 patients (22%) were admitted for neurologic monitoring, and 18 patients (23%) were admitted solely to allow further NAT evaluation. Of those patients admitted, none experienced a neurologic decline and all had nonfocal neurologic exams on discharge. No patient returned to the ER in delayed fashion for a neurologic decline. Of all the patient encounters, no patient required surgery. CONCLUSIONS: Pediatric patients ≤24 months of age presenting to the ER in delayed fashion with scalp swelling after minor head trauma-who were otherwise nonfocal on examination-did not require surgical intervention and did not experience any neurologic decline. Further radiographic investigation did not alter neurosurgical management in these patients; however, it should be noted that workup for child abuse and social care may have been influenced by CT findings, suggesting the need for the future development of a clinical decision-making tool to help safely avoid CT imaging in this setting.

Long-term follow-up and pregnancy after complete sacrectomy with lumbopelvic reconstruction: case report and literature review.

BACKGROUND: Sacrectomy remains a technically complex procedure for resection of malignant pelvic neoplasia. Commonly, postoperative complications include permanent neurological deficits. Only a few studies have reported the long-term functional outcomes of patients who had undergone sacrectomy. CASE PRESENTATION: We previously reported on the utilization of complete sacrectomy and lumbopelvic reconstruction for the management of primary myofibroblastic sarcoma of the sacrum and ilium in a 15-year-old female patient. In this report, we update her postoperative course with an additional 5 years of follow-up and Health-Related Quality of Life (HRQoL) outcomes. During this time period, she gave birth to two healthy full-term babies. CONCLUSION: To the best of our knowledge, this is the first report of pregnancy after total sacrectomy and lumbopelvic reconstruction. We outline some of the challenges in the obstetrical management of this patient.

Trends in epidemiology and hospitalization utilization for myelomeningocele repair from 2000 to 2009.

PURPOSE: Although the incidence of myelomeningocele (MMC) has declined over the past decades with folic acid supplementation and prenatal screening, neural tube defects remain the most common birth defect in the USA. A majority of affected neonates require surgical repair. To characterize US trends in the epidemiology and hospital utilization of MMC repair over the past decade, we analyzed a nationally representative database. METHODS: We queried the Healthcare Cost and Utilization Project (HCUP) Kid's Inpatient Database (KID) for all discharges with procedure code for MMC repair for the years 2000, 2003, 2006, and 2009. The cohorts from these time points were compared for their demographic and in-hospital variables. Results are reported as estimated frequencies and means with 95 % confidence intervals (CI). RESULTS: Sex, race, insurance status, family income level, and mortality of affected infants have not changed significantly over the decade. A majority of neonatal MMC repairs occur in larger hospital bed size and more specialized children's hospital centers. Of patients, 52.3 to 60 % receive VPS placement during the same admission as the primary MMC repair. Total hospital costs for the MMC hospitalizations have remained relatively stable from 42,843 dollars in 2003 to 46,749 dollars in 2009 (adjusted to 2009 dollars). CONCLUSION: Demographics of children having MMC repair have not changed significantly over the past decade, while these surgeries have become more concentrated in pediatric-specialized centers. There appears to be a plateau in public health and access advances with relatively stable cost of MMC hospital care.

Pediatric National Surgical Quality Improvement Program: Useful for Quality Improvement in Craniosynostosis Surgery?

The American College of Surgeons and the American Pediatric Surgical Association collaborate to provide pediatric hospitals with multispeciality surgical outcomes data through the Pediatric National Surgical Quality Improvement Program (NSQIP Peds). The authors used this national multicenter database to describe 30-day outcomes from craniosynostosis surgery and identify associations with perioperative events and blood transfusion.Data from NSQIP Peds were used to describe children undergoing craniosynostosis surgery. The authors examined statistical association of clinical risk factors with the defined end point outcomes of perioperative complications and blood transfusion.Five hundred seventy-two surgeries were included. By Common Procedural Terminology codes, 93 identified as single suture synostosis, the remainder as multiple or unknown suture involvement. Location of the affected suture is not captured. Mean surgical time was 196.84 minutes (SD 113.46). Mean length of stay was 4.22 days (SD 5.04). Sixty-seven percent of patients received blood transfusions. 3.15% were other perioperative occurrences, including infection, wound disruption, unplanned reintubation, stroke/hemorrhage, cardiac arrest, seizures, thromboembolism. 2.8% were readmitted; 2.45% underwent reoperation within 30 days. Duration of surgery and length of hospital stay significantly differed in the presence of blood transfusion versus none. On multivariate analysis, duration from anesthesia start to surgery start, duration from surgery end to anesthesia end, and duration of operation were risk factors for blood transfusion.Pediatric NSQIP gives a national overview of 30-day outcome metrics in craniosynostosis surgery. Perioperative adverse event rate was 3.15%. Duration of surgery and duration of anesthesia were significantly associated with blood transfusion. The authors identified opportunities for pediatric NSQIP database improvement.

Dyspnea and dysphagia from upper airway obstruction after occipitocervical fusion in the pediatric age group.

Upper airway obstruction resulting from overflexion of the craniocervical junction after occipitocervical fusion is a rare but potentially life-threatening complication and is associated with morbidity. The authors retrospectively reviewed the medical records and diagnostic images of 2 pediatric patients who underwent occipitocervical fusion by the Neuro-Spine Program at Texas Children's Hospital and experienced dyspnea and/or dysphagia from new upper airway obstruction in the postoperative period. Patient demographics, operative data, and preoperative and postoperative occiput-C2 angles were recorded. A review of the literature for similar complications after occipitocervical fusion was performed. A total of 13 cases of prolonged upper airway obstruction after occipitocervical fusion were analyzed. Most of these cases involved adults with rheumatoid arthritis. To the best of the authors' knowledge, there have been no previous reports of prolonged upper airway obstruction in children after an occipitocervical fusion. Fixation of the neck in increased flexion (-18° to -5°) was a common finding among these adult and pediatric cases. The authors' cases involved children with micrognathia and comparatively large tongues, which may predispose the oropharynx to obstruction with even the slightest amount of increased flexion. Close attention to a satisfactory fixation angle (occiput-C2 angle) is necessary to avoid airway obstruction after an occipitocervical fusion. Children with micrognathia are particularly sensitive to changes in flexion at the craniocervical junction after occipitocervical fixation.

Morphometric analysis of lumbar pedicles in patients with spinal dysraphism.

BACKGROUND: In patients with open neural tube defects, the incidence of scoliosis and requirement for spinal fusions are increased. Historically, there has been no standardized measurement of vertebral morphometry in these patients. However, anecdotally, patients with open neural tube defects have a more medially oriented lumbar pedicle trajectory than the average population. METHODS: A single-institution retrospective review of patients with open neural tube defects was conducted. The demographic parameters and functional and anatomical levels of the defects were noted. CT and MRI scans of the lumbar spine were analyzed; the pedicles from L 1 to S 1 were measured for width (W), length (L) and midline angle (α). The measurements were compared bilaterally, at each level, and with data from previously published reports. RESULTS: 16 scans of pediatric patients (mean = 3.0 ・} 4.3; age range = 7 days to 14.4 years; 7 males, 9 females) with a diagnosis of either myelomeningocele or lipomyelomeningocele were assessed. Most defects occurred in the lumbar region, with L 2 and L 5 accounting for 37.5% each. All angles demonstrated a quadratic increase from L 1 to S 1 (means: L 1 = 28.3 ・} 5.24° ; L 2 = 29.1 ・} 6.2°; L 3 = 33.2 ・} 6.0°; L 4 = 36.8 ・} 5.6°; L 5 = 43.8 ・} 5.9°; S 1 = 52.0 ・} 3.6°) and were more medially angulated than those reported previously; no significant difference existed between right and left measurements (W = 0.65 ≤ p ≤ 0.94; L = 0.91 ≤ p ≤ 1; α = 0.24 ≤p ≤0.86). CONCLUSIONS: Patients with open neural tube defects had more medially angled pedicle trajectories in the lumbar spine when compared to previously reported values.

Clinical outcomes of the surgical treatment of isolated unilateral facet fractures, subluxations, and dislocations in the pediatric cervical spine: report of eight cases and review of the literature.

PURPOSE: We present a small series consisting of eight children with unilateral facet injury of the cervical spine treated surgically. METHODS: A retrospective review was performed. Injury data, radiographs, surgical data, and outcomes (Neck Disability Index (NDI), Short Form 36 (SF-36), and Visual Analog Scale for Neck Pain (VAS-NP)) were collected from seven patients. A literature review was performed for one additional case. RESULTS: Motor vehicle accidents (62 %, n = 5) and falls (38 %, n = 3) accounted for all injuries. The C6-7 level accounted for most of the injuries (37.5 %, n = 3). The mean NDI score with at least 3 months follow-up was 5.3 (n = 6, range, 1-12; standard deviation, 4.5), corresponding to mild disability. Of the norm-based SF-36 scale scores available (n = 6), the mean physical functioning (PF), role-physical (RP), and role-emotional (RE) scores were significantly less than the adult, age 18-24, norm-based means, with a mean difference of -6.4, -9.13, and -11.3, respectively (p value = 0.03, 0.001, and 0.01, respectively). The mean general health (GH) and vitality (VT) scores, however, were significantly greater than the adult, age 18-24, norm-based mean, with a mean difference of 7.82 and 10.3 (p = 0.04 and 0.02, respectively). VAS-NP showed a return to the "no pain" level at 3 months or more follow-up in all patients. CONCLUSIONS: We suggest that surgical treatment of these injuries in the pediatric age group may lead to satisfactory clinical and radiographic outcomes, but HRQoL analysis suggests that patients remain physically and emotionally disabled to some degree after surgery.

Rh-BMP-2 for L5-S1 arthrodesis in long fusions to the pelvis for neuromuscular spinal deformity in the pediatric age group: analysis of 11 patients.

PURPOSE: Neuromuscular scoliosis is a challenging pathology to treat with high incidence of complications and failure of surgical fusion. Surgical correction can entail long fusion constructs extending to the pelvis. We report our experience in the use of bone morphogenetic protein (BMP) to augment L5-S1 arthrodesis in long segment fusions in pediatric patients with neuromuscular scoliosis. METHODS: Retrospective review of 11 pediatric patients with neuromuscular spinal deformity (mean, age 13.7 years; range, 10-20 years) who underwent long (mean, 15 levels; range, 10-18 levels) spinal instrumentation and fusion to the pelvis at a single institution from 2007 to 2012 with an average follow-up of 34 months (range, 11-62 months). RESULTS: Of the 11 patients, one had pseudoarthrosis at L5-S1. The average coronal Cobb angle measured 59° before surgery and 42° immediately after surgery. The average preoperative thoracic kyphosis and lumbar sagittal lordosis measured 34 and 59°, respectively. Immediately after surgery, the thoracic and lumbar angles measured 28 and 39°, respectively. At last follow-up, the average coronal Cobb angle was maintained at 43° and the thoracic and lumbar sagittal angles were 28 and 44°, respectively. An average of 14.2 mg of recombinant human bone morphogenetic protein-2 (rh-BMP-2) was used for each case. CONCLUSIONS: L5-S1 arthrodesis may be effectively achieved in long fusions for pediatric neuromuscular spinal deformity with posterolateral fusion supplemented with rh-BMP-2. This surgical strategy may be associated with lower complication rates, decreased blood loss, and shorter operative times than circumferential fusion, which is particularly important in this complex fragile patient population.

Multilevel thoracic hemangioma with spinal cord compression in a pediatric patient: case report and review of the literature.

PURPOSE: Vertebral hemangiomas are common benign vascular tumors of the spine. It is very rare for these lesions to symptomatically compress neural elements. If spinal cord compression does occur, it usually involves only a single level. Multilevel vertebral hemangiomas causing symptomatic spinal cord compression have never been reported in the pediatric population to the best of our knowledge. METHODS: We report the case of a 15-year-old boy presenting with progressive paraparesis due to thoracic spinal cord compression from a multilevel thoracic hemangioma (T5-T10) with epidural extension. RESULTS: Because of his progressive neurological deficit, he was initially treated with urgent multilevel decompressive laminectomies from T4 to T11. This was to be followed by radiotherapy for residual tumor, but the patient was unfortunately lost to follow-up. He re-presented 3 years later with recurrent paraparesis and progressive disease. This was treated with urgent radiotherapy with good response. As of 6 months follow-up, he has made an excellent neurological recovery. CONCLUSIONS: In this report, we present the first case of a child with multilevel vertebral hemangiomas causing symptomatic spinal cord compression and review the literature to detail the pathophysiology, management, and treatment of other cases of spinal cord compression by vertebral hemangiomas.

Pediatric iatrogenic thoracic kyphosis and tension myelopathy treated with a thoracic pedicle subtraction osteotomy: a case report and review of the literature.

PURPOSE: Pediatric kyphotic deformity is an uncommon clinical entity that can occur following posterior spinal operations and has significant complexity in its treatment. Tension myelopathy in a pediatric patient with a thoracic kyphotic deformity has not been reported in the literature. CASE REPORT: We present a 17-year-old boy with a progressive thoracic kyphosis and tension myelopathy 4 years after he underwent a thoracic laminoplasty at an outside institution for the treatment of a dorsal spinal arachnoid cyst. At our institution, he was treated with a pedicle subtraction osteotomy as well as thoracic Ponte osteotomies for sagittal plane correction to relieve the tension myelopathy. CONCLUSIONS: Both clinical and radiographic improvements were observed after surgery. We review the literature on pediatric thoracic kyphosis and tension myelopathy and the treatment of these pathologies.

A review of pediatric lumbar spine trauma.

Pediatric spine fractures constitute 1%-3% of all pediatric fractures. Anywhere from 20% to 60% of these fractures occur in the thoracic or lumbar spine, with the lumbar region being more affected in older children. Younger children tend to have a higher proportion of cervical injuries. The pediatric spine differs in many ways from the adult spine, which can lead to increased ligamentous injuries without bone fractures. The authors discuss and review pediatric lumbar trauma, specifically focusing on epidemiology, radiographic findings, types and mechanisms of lumbar spine injury, treatment, and outcomes.

Craniosynostosis surgery: the legacy of Paul Tessier.

Paul Louis Tessier is recognized as the father of craniofacial surgery. While his story and pivotal contributions to the development of the multidisciplinary practice of craniofacial surgery are much highlighted in plastic surgery literature, they are seldom directly discussed in the context of neurosurgeons. His life and legacy to craniosynostosis and neurosurgery are explored in the present paper.

The impact of social determinants of health on early outcomes after adult Chiari surgery.

We sought to identify social determinants of health (SDoH) for adult patients undergoing Chiari decompression surgery and to analyze their association with postoperative outcomes, including length of stay (LOS), return to the system within 30 days, and the Chicago Chiari Outcomes Score (CCOS). This is a retrospective study of adult patients who underwent Chiari decompression surgery between June 2021 and January 2023. Data was gathered through electronic medical record review and telephone surveys. Descriptive statistics were used to evaluate demographics of all patients meeting inclusion criteria. Fisher's exact tests and logistic regression were used for data analysis. A total of 37 patients underwent Chiari decompression (23 CCOS/SDoH survey respondents): 48% bony decompression only, 30% bony decompression plus intradural exploration, and 22% occipitocervical fusion. Seven patients (30%) had a LOS > 2 days, 1 patient (4%) required inpatient rehabilitation postoperatively, 4 patients (17%) returned to the system within 30 days, 10 patients (43%) had an extremely favorable CCOS (15-16), and 11 patients (48%) reported interaction with a Chiari support group. Mean follow-up was 9.5 months. Patients with occipitocervical fusion were more likely to have a LOS > 2 days (p = 0.03), patients who exercised ≥ 3 days per week were more likely to have a favorable CCOS (p = 0.04), and patients who participated in a Chiari support group were less likely to have a favorable CCOS (p = 0.03). Chiari decompression plus occipitocervical fusion may be associated with increased LOS. While more frequent exercise may be associated with better post-surgical outcomes, participation in a Chiari support group may be correlated with worse outcomes.

Clinical Research Primer for Medical Students: Overview and Illustrative Experiences.

Background The ability to participate in clinical scholarship is a foundational component of modern evidence-based medical practice, empowering improvement across essentially every aspect of clinical care. In tandem, the need for comprehensive exposure to clinical research has been identified as a critical component of medical student training and preparation for residency that is underserved by traditional undergraduate medical education models. The goal of the current work was to provide guidelines and recommendations to assist novice medical students in taking ownership of their research education. Methods The Clinical Research Primer was composed from pooled research documents compiled by the study authors and our institutional neurosurgery student research group. The Primer was then structured as the natural evolution of a research project from its inception through the submission process. Results We divided the foundational components of the Clinical Research Primer into seven domains, each representing a landmark in the development of a peer-reviewed study, and a set of skills critical for junior scholars to develop. These vital components included the following: pitching and designing clinical studies, developing a research workflow, navigating the Institutional Review Board, data collection and analysis, manuscript writing and editing, submission mechanics, and tracking research projects for career development. Conclusion We anticipate that the tools included in the Clinical Research Primer will increase student research productivity and preparedness for residency. Although our recommendations are informed by our experiences within neurosurgery, they have been written in a manner that should generalize to almost any field of clinical study.
