Subtle fractures in children

PURPOSE: The skeletal survey X-ray series is the current 'gold standard' when investigating suspected physical abuse (SPA) of children, in addition to a non-contrast computed tomography (CT) brain scan. This systematic literature review synthesised findings of published research to determine if low dose computed tomography (LDCT) could detect subtle fractures and therefore replace the skeletal survey X-ray series in the investigation of SPA in children aged under 3 years. METHODS: Five electronic databases and grey literature were systematically searched from their inception to 28 April 2022...

BACKGROUND: Fractures are a common presentation of non-accidental trauma (NAT) in the pediatric population. However, the presentation could be subtle, and a high degree of suspicion is needed not to miss NAT. OBJECTIVE: To analyze a comprehensive database, providing insights into the epidemiology of fractures associated with NAT. PARTICIPANTS AND SETTING: The TriNetX Research Network was utilized for this study, containing medical records from 55 healthcare organizations...

Post-mortem computed tomography (PMCT) imaging is gaining popularity and acceptance for use alongside forensic autopsies of children, predominantly to aid in the detection of traumatic injuries. Recent research on this topic has provided a breadth of new information regarding the appropriate usage, imaging guidance, and diagnostic accuracy for the identification of different paediatric pathologies. Additionally, advanced CT imaging techniques, such as PMCT angiography or ventilated PMCT, have been trialled, and post-mortem micro-CT is now being used in specialist centres for the assessment of subtle fractures in extracted bone specimens...

BACKGROUND: Avoidant/restrictive food intake disorder (ARFID) is an eating/feeding disturbance characterized by severe food avoidance or restriction that results in faltering growth, nutritional deficiencies, dependence on formula supplementation, and/or significant psychosocial impairment. Compared to other eating disorders, ARFID is observed to have an earlier childhood onset and chronic course without intervention. Childhood represents a sensitive period for longitudinal growth and bone accrual, setting the stage for long-term health outcomes associated with longevity and quality of life, including risk for fracture and osteoporosis...

BACKGROUND: Missed fractures are the leading cause of diagnostic error in the emergency department, and fractures of pediatric bones, particularly subtle wrist fractures, can be misidentified because of their varying characteristics and responses to injury. OBJECTIVE: This study evaluated the utility of an object detection deep learning framework for classifying pediatric wrist fractures as positive or negative for fracture, including subtle buckle fractures of the distal radius, and evaluated the performance of this algorithm as augmentation to trainee radiograph interpretation...

UNLABELLED: Infants < 3 months with minor head trauma (MHT) are a particularly vulnerable group, though few studies have focused specifically on these patients. We aimed to evaluate the application of the PECARN prediction rule, designed for clinically important traumatic brain injury (ciTBI) in children < 2 years in infants < 3 months, and create a specific prediction rule for this population. We conducted a prospective multicenter observational study in 13 pediatric emergency departments (PEDs) in Spain...

Missed or delayed diagnosis of fractures in children is not uncommon owing to their immature skeletons, unique fracture patterns, and distinctive radiologic findings. The term occult is used to describe radiographically subtle fractures. Some of these fractures can be associated with excellent outcomes despite the pitfalls of delayed diagnosis. However, a subset of these injuries have more guarded prognoses when missed, despite their harmless radiographic appearance. A high index of suspicion should be maintained when treating pediatric extremity injuries with clinical findings disproportionate to a benign-appearing radiograph...

Introduction: Accurately distinguishing between stable and unstable isolated distal radius fractures (DRF) in children allows for appropriate fracture-specific treatment. Although fractures with cortical disruption, displacement, or angulation are unstable, distinguishing stable buckle fractures (BF) from more subtle potentially unstable DRF is challenging. Our quality improvement project aimed to improve radiology reporting accuracy for these subtle fractures from 23% to 90% in a large tertiary pediatric hospital...

A 7-year-old boy presented 6 weeks after open reduction and crossed Kirschner wire (K-wire) fixation of a supracondylar humerus fracture. Previous treatments had restored skeletal anatomy without documented complications. However, the patient would not move the entire arm, including his forearm and hand. Any passive movement led to anxious adverse reactions, and there was partial numbness of all fingers. After intensive physio- and occupational therapy supported by nerve stimulation and psychological counseling, anxiety-related functional deficits of the shoulder and elbow resolved to reveal the severe Volkmann contracture of the right hand developed fully...

INTRODUCTION: Rickets is typically characterized by bone deformities due to defective bone mineralization and chondrocyte maturation in growing bones. However, infantile rickets often goes unrecognized, because the skeletal abnormalities are more subtle and often can only be detected radiologically. Nutritional rickets is a major public health concern in several regions worldwide. It is most commonly caused by vitamin D and/or calcium deficiency. AREA COVERED: We provide an overview of historical perspective, epidemiology, and pathophysiology of nutritional rickets...

BACKGROUND: Supracondylar humerus fractures (SHF) are the second most common fracture in children and the most common fracture in children under seven years. Subtle neurovascular lesions in displaced SHF may be underdiagnosed clinically, but their sequelae can mean life-long symptoms. Here we show that color-coded duplex ultrasound (DUS) could help to identify these patients. METHODS: We reviewed records of 229 children who had recovered from SHF. Ninety patients were available for detailed questionnaires, in-depth neurovascular examinations, and DUS...

UNLABELLED: Specific knowledge of the features of minor head trauma in infants is necessary to develop appropriate preventive strategies and adjust clinical management in pediatric emergency departments (PEDs). The aim of this study is to describe the epidemiology of minor blunt head trauma in infants < 3 months who present to PEDs. We performed a prospective study of infants evaluated in any of 13 Spanish PEDs within 24 h of a minor head trauma (Glasgow Coma Scale scores of 14-15) between May 2017 and November 2020...

In this retrospective study , we present the findings in 250 homicides by asphyxia in Denmark in a 25-year period, with a particular focus on the autopsy findings in strangulation. Our intention is for the results to be used in future death investigations, where difficulties in interpretation of findings in potential asphyxial deaths arise. Asphyxia homicides showed a strong bias with respect to sex, age, and homicide type. The frequent female victim was typically an adult, whereas the rarer male victim was most often a child...

Avulsion injuries result from the application of a tensile force to a musculoskeletal unit or ligament. Although injuries tend to occur more commonly in skeletally immature populations due to the weakness of their apophysis, adults may also be subject to avulsion fractures, particularly those with osteoporotic bones. The most common sites of avulsion injuries in adolescents and children are apophyses of the pelvis and knee. In adults, avulsion injuries commonly occur within the tendon due to underlying degeneration or tendinosis...

Lateral condyle fracture of the humerus is the second most common paediatric elbow fracture and is often missed, which can result in severe consequences including malunion, growth arrest and tardy ulnar nerve palsy. The difficulty in managing this fracture stems from a lack of awareness and the often subtle findings on radiographs. Patients can also present with quite vague symptoms; clinicians who do not have a high index of suspicion may not investigate beyond the initial clinical assessment and could miss vital cues...

INTRODUCTION AND IMPORTANCE: Legg-Calvé-Perthes disease (LCPD) sometimes occur in children, however it is difficult to diagnose it at the early stage especially in the cases there are no complaints of symptoms. Femoral shaft fractures in children cause various complications such as leg-length discrepancy, nonunion and malunion, refracture, and osteonecrosis of the femoral head. We presented a rare case in which a pediatric patient developed LCPD after femoral shaft fracture. CASE PRESENTATION: A healthy 8-year-old boy sustained a left femoral diaphyseal fracture following a pedestrian car accident...

STUDY OBJECTIVE: Infants with head trauma often have subtle findings suggestive of traumatic brain injury. Prediction rules for traumatic brain injury among children with minor head trauma have not been specifically evaluated in infants younger than 3 months old. We aimed to determine the risk of clinically important traumatic brain injuries, traumatic brain injuries on computed tomography (CT) images, and skull fractures in infants younger than 3 months of age who did and did not meet the age-specific Pediatric Emergency Care Applied Research Network (PECARN) low-risk criteria for children with minor blunt head trauma...

Suboptimal vitamin D status is a global health issue that affects children and adults worldwide. The prevalence of vitamin D deficiency and insufficiency has been well documented in the pediatric population in the United States. Although vitamin D deficiency is common, radiographic findings are uncommon and can be subtle. Additionally, because of the high prevalence of pediatric vitamin D insufficiency, it is commonly identified in young children with fractures. However, the majority of pediatric fractures are caused by trauma to healthy bones...

Skull fractures are common in the pediatric population following head trauma and are estimated to occur post head trauma in 11% of children younger than 2 years. A skull fracture indicates potential underlying intracranial injury and might also help explain the mechanism of injury. Multiple primary and accessory sutures complicate the identification of non-depressed fractures in children younger than 2 years. Detection of linear skull fractures can be difficult on two-dimensional (2-D) CT and can be missed, particularly when the fracture is along the plane of image reconstruction...

Sternal fractures have often been associated with high-impact thoracic trauma. In children, this is not always the case. X-ray and even computed tomography can miss subtle sternal fractures. Point-of-care ultrasound has been shown to be more sensitive and specific for detecting subtle sternal fractures as compared with plain X-ray. The following 2 cases describe sternal fractures that were missed by traditional imaging modalities, including a fracture missed by chest computed tomography. They also highlight other potential causative mechanisms for sternal fractures in children, including hyperflexion injuries and low-mechanism motor vehicle accidents...
