Background: Despite guideline support for plain radiography (XR) in low-risk pediatric blunt trauma, CT remains the predominant imaging modality for cervical spine evaluation, increasing radiation exposure. We evaluated contemporary XR utilization and its diagnostic performance in children meeting consensus criteria for XR-first imaging. Study Design: We performed a prospective, multicenter observational study of 19,995 children enrolled in the Western Pediatric Cervical Spine Study across 72 U.S. trauma centers (2022–2025). Children appropriate for XR screening (Glasgow Coma Scale score >13, asymptomatic, non-obtunded) were identified using consensus criteria. XR utilization, sensitivity, and negative predictive value (NPV) were assessed, and multivariable logistic regression identified predictors of XR use. Results: XR was performed in 39% of patients overall and varied significantly by trauma center type (pediatric 48% vs adult 14% vs mixed 15%; p<0.001), whereas CT was used in 60%. Among XR-appropriate children (n=12,650), an estimated 7,705 CT examinations could potentially have been replaced with XR. In the overall cohort, XR sensitivity for any cervical spine injury was 30.3% (95% CI 26.2–34.6%) with an NPV of 95.2% (95% CI 94.7–95.7%). In XR-appropriate children, only two clinically significant cervical spine injuries were missed, yielding a sensitivity of 75.0% (95% CI 34.9–96.8%) and an NPV of 99.9% (95% CI 99.9%–100.0%). Conclusions: Plain radiography is substantially underutilized in children meeting consensus criteria for XR-first imaging. In appropriately selected patients, XR demonstrated an NPV of 99.9% for clinically significant cervical spine injury, supporting broader implementation of XR-first imaging strategies to reduce CT utilization and pediatric radiation exposure.

Study Design. Subanalysis of a prospective, multicenter, observational study at 72 US adult, pediatric, and mixed trauma centers. Objective. We investigated trauma-related risk factors and patient-level factors associated with multiregional spinal column injury, defined as cervical spine injury (CSI) requiring treatment and thoracolumbar injury (TLI). Summary of Background Data. Traumatic spinal injury causes morbidity and mortality in pediatric patients. Injuries to multiple spinal column regions require early identification and thoughtful management. Methods. All children <18 years undergoing cervical spine evaluation after blunt multisystem trauma were prospectively identified and enrolled. Clinically significant CSI was defined by cervical spine surgery or halo placement. TLI incidence and management was recorded. The primary outcome was multiregional spinal column injury (CSI+TLI). Results. Of 19,651 enrolled patients, 1484 children (7.5%) experienced a TLI, 159 (0.81%) had CSI requiring treatment, and 30 (0.15%) had CSI+TLI. Multivariate analysis revealed that the trauma-related factors mechanism of injury ( P <0.001), rib fractures (odds ratio (OR) 2.8 [2.3-3.4]), hemothorax/pneumothorax (OR 2.0 [1.7-2.4]), bowel injury (OR 4.0 [2.9-5.4]), pelvic fracture (OR 1.5 [1.2-1.9]), and clinically significant CSI (OR 1.9 [1.2-2.9]) were independently associated with TLI. Of the 159 children with clinically significant CSI, 30 also experienced TLI (19%). Multivariate analysis identified prehospitalization intubation (OR 3.1 [1.1-8.4]) and rib fractures (OR 3.9 [1.2-12.8]) as independent associations with CSI+TLI. Conclusions. Of children with CSI requiring treatment, 19% experienced TLI. MOI and various trauma-related injuries were independently associated with TLI, whereas prehospitalization intubation and rib fractures were independent risk factors for CSI+TLI. These factors should trigger screening for multiregional spinal column injury in pediatric trauma patients. Furthermore, if there is known TLI, the cervical spine should be evaluated, and if there is significant CSI, then dedicated imaging of the thoracic and lumbar spine is indicated. Level of Evidence.

Background In pediatric patients presenting after blunt trauma, the incidence of clinically significant cervical spine injury (CSI) is approximately 1%. Although multidetector CT (MDCT) is widely accepted for cervical spine clearance in adults, its utility in children remains uncertain. The purpose of this study is to evaluate the sensitivity of MDCT in identifying clinically significant CSI in pediatric patients, stratified by age groups: adolescents (12 years to 17 years) and children (0 years to 11 years). Methods We designed a national, multicenter, prospective observational study to assess the diagnostic performance of MDCT in detecting clinically significant CSI in pediatric trauma patients. Data are being collected from participating centers on imaging findings, clinical outcomes, and the presence of confirmed CSIs after blunt trauma. The analysis plan includes stratification by age group and calculation of sensitivity, specificity, and predictive values of MDCT for CSI. Results This abstract outlines the background, methodology, and analytical framework of the study. Data collection and analysis are ongoing. This study represents the largest known cohort of pediatric patients undergoing cervical spine imaging after blunt trauma and is the first prospective study of its kind focused exclusively on this population. Conclusions This study will provide critical data to inform guidelines for pediatric cervical spine clearance after blunt trauma. By evaluating the sensitivity of MDCT in detecting clinically significant CSI, the findings aim to support evidence-based imaging strategies and improve the safety and efficiency of pediatric trauma care.

Objectives Cervical spine (c-spine) X-ray (XR) remains an important tool for pediatric trauma patients. XR is a low radiation alternative to multidetector CT (MDCT). Our primary aims were to analyze the sensitivity of a negative c-spine XR and to analyze what factors lead to additional imaging after a negative c-spine XR. Methods A retrospective cohort study was conducted at a level 1 pediatric trauma center from 2012 to 2021. We compared the group with negative c-spine XR and no additional imaging to the group with negative c-spine XR followed by additional c-spine MDCT and/or MRI. Results There were 2,081 negative XRs and 1,974 (95%) had their c-spines cleared without additional imaging. No patient required an operation for a clinically significant c-spine injury in this group, and we consider this no missed injuries. The remaining 108 patients had additional c-spine imaging after negative c-spine XR for c-spine clearance (24 MDCT, 76 MRI, 8 MDCT and MRI). Indications for additional c-spine imaging were pain (48.1%), Glasgow Coma Scale (GCS) score ≤14 (43.5%), and paresthesia (8.3%). Patients who received additional imaging were more likely to have a GCS score ≤12 (25.4% vs 4.1%), Injury Severity Score >15 (21.9% vs 8.1%), Level 1 Trauma activation (21% vs 5%), Abbreviated Injury Scale head score of 4 or 5 (29% vs 5%), be intubated (30% vs 2%), and have non-accidental trauma as their mechanism of injury (20% vs 1%) (p value<0.0001, for all). Five patients who received additional imaging were treated with a cervical collar, but no operative intervention. Conclusions In this cohort, screening XR had a sensitivity of 100% for clinically significant c-spine injuries. GCS was the most significant predictor of obtaining additional imaging. A negative XR combined with a normal physical examination in an evaluable pediatric patient is a safe way of clearing the c-spine. Level of evidence Study contains level III evidence.

Abstract BACKGROUND Our institution recently transitioned from paravertebral nerve blocks (PVB) to intercostal nerve cryoablation (INC) for pain control following minimally invasive repair of pectus excavatum (MIRPE). This study aimed to determine how INC affected the operative time, length of stay, complication rates, inpatient opioid use, and outpatient prescription of opioids at a single center. METHODS A retrospective review was performed at a single pediatric referral center of all patients who underwent MIRPE between 2018–2023. Patient demographics, operative details, and perioperative course were collected. The use of INC versus PVB was recorded. Univariate analyses were performed using Wilcoxon rank sum tests for continuous variables and chi-squared tests for categorical variables. RESULTS 255 patients were included with a median age of 15 years, median BMI of 18.50 kg/m2, and median Haller index of 4.40. INC was utilized in 41% (105/255), and 59% (150/255) received PVB. The two groups did not differ significantly in BMI, Haller index, or complications, though the INC patients were older by 1 year (15.0 vs 16.0, p = 0.034). INC was associated with an increased operative time (INC: 92 min vs. PVB: 67 min, p < 0.001), decreased length of stay (3 vs. 4 days, p = < 0.001), more than 2-fold decrease in inpatient opioids per day (INC: 16 (MME) vs PVB 41 (MME), p < 0.001), and a four-fold decrease in the amount of opioids prescribed at discharge (INC: 90 MME) vs PVB 390 MME, p < 0.001). CONCLUSION INC after MIRPE significantly decreased both the inpatient opioid utilization and our outpatient prescribing practices while also decreasing our overall length of stay without increasing complications. Level of Evidence: Level III

Superior mesenteric artery syndrome (SMAS) is a rare and potentially life-threatening cause of small bowel obstruction in which the superior mesenteric artery impinges on the third portion of the duodenum. SMAS is typically encountered in patients with low body fat and a history of rapid weight loss and is often diagnosed as a chronic or subacute condition. Here, we describe a case of a healthy adolescent boy without typical SMAS prodromal symptoms presenting with a severe, hyperacute proximal small bowel obstruction due to SMAS. Complications arising from massive gastric and duodenal distension, including gastric, pancreatic and renal ischaemia, necessitated emergent surgical intervention consisting of the duodenojejunostomy bypass with partial gastric resection. The patient recovered without significant lasting consequences.

Objective: This study aims to determine if outpatient opioid prescriptions are associated with future SUD diagnoses and overdose in injured adolescents 5 years following hospital discharge. Summary of Background Data: Approximately, 1 in 8 adolescents are diagnosed with an SUD and 1 in 10 experience an overdose in the 5 years following injury. State laws have become more restrictive on opioid prescribing by acute care providers for treating pain, however, prescriptions from other outpatient providers are still often obtained. Methods: This was a retrospective cohort study of patients ages 12–18 admitted to 2 level I trauma centers. Demographic and clinical data contained in trauma registries were linked to a regional database containing 5 years of electronic health records and prescription data. Regression models assessed whether number of outpatient opioid prescription fills after discharge at different time points in recovery were associated with a new SUD diagnosis or overdose, while controlling for demographic and injury characteristics, and depression and posttraumatic stress disorder diagnoses. Results: We linked 669 patients (90.9%) from trauma registries to a regional health information exchange database. Each prescription opioid refill in the first 3 months after discharge increased the likelihood of new SUD diagnoses by 55% (odds ratio: 1.55, confidence interval: 1.04–2.32). Odds of overdose increased with ongoing opioid use over 2–4 years post-discharge (P = 0.016–0.025). Conclusions: Short-term outpatient opioid prescribing over the first few months of recovery had the largest effect on developing an SUD, while long-term prescription use over multiple years was associated with a future overdose.
