Background: Elbow fractures are the most common pediatric fractures requiring operative treatment. Although recent reports have suggested that the COVID-19 pandemic has markedly reduced the incidence of pediatric fractures, no study has specifically evaluated the impact on pediatric elbow fractures. This study aimed to evaluate changes in the incidence, severity, and resource utilization for managing pediatric elbow fractures during the COVID-19 pandemic, compared with prepandemic years. Methods: A prepandemic (2007 to 2017) cohort and a COVID-19 pandemic period (March 2020 to March 2021) cohort of pediatric elbow injuries from a single tertiary hospital were retrospectively examined and compared. Exclusion criteria included outside treatment or lack of diagnosis by an orthopedist. Presentation information, injury patterns, transport, and treatment requirements were collected. Results: Although the incidence of pediatric elbow fractures and rate of neurovascular injury were comparable, seasonal patterns were not sustained and the rate of fracture displacement was found to be significantly elevated in the COVID-19 period compared with nonpandemic years. Likewise, marked changes to where patients first presented (emergency department vs. Clinic), how the patients were transported, and the distance traveled for care were observed. Specifically, patients were more likely to present to the clinic, were more likely to self-transport instead of using emergency medical service transportation, and traveled a greater distance for care, on average. Aligning with these changes, the resources utilized for the treatment of pediatric elbow fracture markedly changed during the COVID-19 period. This study found that there was an increase in the overall number of surgeries performed, the total operative time required to treat elbow fractures, and the number of patients requiring admission during the COVID-19 period. Conclusions: These data provide a contrasting viewpoint to prior reports, illustrating that the incidence of elbow fractures remained consistent during the COVID-19 period, whereas the operative volume and need for hospital admission increased compared with years prior. Furthermore, this study demonstrated how the COVID-19 pandemic altered the interface between pediatric patients with elbow fractures and our institution regarding the location of presentation and transportation. Level of Evidence: Level III—retrospective cohort study.

Purpose: The presence of soft tissue injury in pediatric supracondylar humerus fractures (SCHFs) has been shown to be an independent predictor of any neurovascular injury. Potentially expanding this concept, the specific neurovascular structure injured around the elbow is thought to be dependent upon the direction and magnitude of fracture displacement and subsequent soft tissue injury. Therefore, it was hypothesized that the bruise location following SCHF is indicative of the anatomic location of maximal soft tissue injury and therefore is a specific prognosticator of which neurovascular structure may be injured. Methods: Retrospective chart review of all SCHFs treated at a tertiary pediatric hospital from 2007 to 2017 collected information on bruise location, neurovascular injury patterns, and outcomes. Bruise location was classified as anterior, anterolateral, anteromedial, or posterior. Injury radiographs were reviewed by a blinded pediatric orthopaedic surgeon to neurovascular structure injured. Results: Of 2845 SCHFs identified, 267 (9.4%) had concomitant neurovascular injury—of which 128 (47.9%) met inclusion criteria. Among the vascular injuries, all bruising was anteromedial (28/45, 62.2%, P <0.05) or anterior (17/45, 37.8%, P >0.05). Fractures with anteromedial bruising correlated with median nerve injury (24/27, 88.9%, P <0.05), whereas fractures with anterolateral bruising correlated with radial nerve injuries (24/25, 96.0%, P <0.05). Bruising or radiographic evaluation correctly identified 60.2% and 64.1% of neurovascular injuries, respectively, whereas the combination identified 82.0% of neurovascular injuries correctly. Bruise location identified 23 neurovascular injuries not predicted by radiographic evaluation alone. Conclusion: Bruise location is an important physical examination finding that can be used as an adjunct to improve the diagnostic accuracy of neurovascular injury in SCHFs in conjunction with neurovascular physical examination and radiographic evaluation. SCHFs with anterior or anteromedial bruising should raise concern for vascular injury. In addition, anteromedial bruising is predictive of a median nerve injury and anterolateral bruising is predictive of radial nerve injury. This adjunct diagnostic is particularly helpful in a noncooperative child or if performed by a clinician with limited experience in diagnosing neurovascular injuries or interpreting pediatric elbow radiographs. Level of Evidence: Level IV, case series.

The childhood obesity epidemic involves unusual and underrecognized complications associated with this clinical and public health problem. Obesity hypoventilation syndrome (OHS) is defined as the triad of obesity, daytime hypoventilation, and sleep-disordered breathing in the absence of an alternative neuromuscular, mechanical or metabolic explanation for hypoventilation. We herewith report a 12-year-old boy who was diagnosed with OHS. The patient improved with phlebotomy and bi-level positive airway pressure. To the best of our knowledge, this is the first reported case of secondary polycythemia due to OHS requiring therapeutic phlebotomy.

Background: Nonaccidental trauma (NAT) is a rising source of morbidity and mortality in the pediatric population. Fractures are often the first cause for presentation to health care providers in the case of NAT but can be misidentified as accidental. Given that elbow fractures are the most common accidental injuries among pediatric patients, they are not traditionally associated with NAT. This study aims to determine the prevalence of NAT among elbow fractures and identify common features in nonaccidental elbow fractures. Methods: Current Procedural Terminology (CPT) codes were used to retrospectively identify all pediatric (0 to 17) elbow fractures at a single, tertiary children’s hospital between 2007 and 2017. Among these, all fractures for which an institutional child abuse evaluation team was consulted were identified. The medical record was then used to determine which of these fractures were due to NAT. Standard injury radiographs of all victims of NAT as well as all patients under 1 year of age were blinded and radiographically evaluated for fracture type by a pediatric orthopaedic surgeon. Results: The prevalence of nonaccidental elbow fractures across the 10-year study period was 0.4% (N=18). However, the prevalence of nonaccidental elbow fractures in those patients below 1 year of age was markedly higher at 30.3% (10/33). Among all elbow fractures in patients below 1 year of age, supracondylar humerus fractures were the most common fracture type (19/33, 57.6%), yet transphyseal fractures (6/33, 18.1%) were most commonly the result of NAT (5/6, 83.3%). In children over 1 year of age, fracture type was not an indicator of NAT. Conclusions: The vast majority of pediatric elbow fractures (99.6%) are accidental. However, certain factors, namely age below 1 year and transphyseal fractures increase the likelihood that these fractures may be a result of NAT. Level of Evidence: Level IV: retrospective case series.
