Limb fractures and nonaccidental injury in children less than 24 months of age:

The incidence of fractures in children under two years of age: a systematic review

BACKGROUND

Epidemiological research on fractures in children under the age of two is of great importance to help understand differences between accidental and abusive trauma.

OBJECTIVE

This systematic review aimed to evaluate studies reporting on the incidence of fractures in children under two years of age, excluding birth injuries. Secondary outcome measures included fracture location, mechanisms of injury and fracture characteristics.

METHODS

A systematic literature review (1946 to February 7th 2024), including prospective and retrospective cohort studies and cross-sectional cohort studies, was performed. Studies including children from other age groups were included if the actual measures for those aged 0-2 years could be extracted. We also included studies restricted to infants. Annual incidence rates of fractures were extracted and reported as the main result. Critical appraisal of was performed using the Appraisal tool for Cross-Sectional Studies.

RESULTS

Twelve moderate to good quality studies met eligibility criteria, of which seven were based on data from medical records and five were registry studies. Studies investigated different aspects of fractures, making comprehensive synthesis challenging. There was an overall annual fracture incidence rate of 5.3 to 9.5 per 1,000 children from 0-2 years of age; with commonest sites being the radius/ulna (25.2-40.0%), followed by tibia/fibula (17.3-27.6%) and the clavicle (14.6-14.8%) (location based on 3 studies with a total of 407 patients). In infants, the reported incidence ranged between 0.7 to 4.6 per 1,000 (based on 3 studies), with involvement of the clavicle in 22.2% and the distal humerus in 22.2% of cases (based on 1 study). Only a single metaphyseal lesion was reported (proximal humerus of an 11-month-old infant). Fracture mechanisms were detailed in four studies, with fall from chair, bed, table, own height or fall following indoor activities causing 50-60% of fractures.

CONCLUSIONS

There is a paucity of good quality data on fracture incidence in children under the age of two. Larger, prospective and unbiased studies would be helpful in determining normal pattern of injuries, so that differences from abusive trauma may be better understood.

Predictive value of indicators for identifying child maltreatment and intimate partner violence in coded electronic health records: a systematic review and meta-analysis

OBJECTIVE

Electronic health records (EHRs) are routinely used to identify family violence, yet reliable evidence of their validity remains limited. We conducted a systematic review and meta-analysis to evaluate the positive predictive values (PPVs) of coded indicators in EHRs for identifying intimate partner violence (IPV) and child maltreatment (CM), including prenatal neglect.

METHODS

We searched 18 electronic databases between January 1980 and May 2020 for studies comparing any coded indicator of IPV or CM including prenatal neglect defined as neonatal abstinence syndrome (NAS) or fetal alcohol syndrome (FAS), against an independent reference standard. We pooled PPVs for each indicator using random effects meta-analyses.

RESULTS

We included 88 studies (3 875 183 individuals) involving 15 indicators for identifying CM in the prenatal period and childhood (0-18 years) and five indicators for IPV among women of reproductive age (12-50 years). Based on the International Classification of Disease system, the pooled PPV was over 80% for NAS (16 studies) but lower for FAS (<40%; seven studies). For young children, primary diagnoses of CM, specific injury presentations (eg, rib fractures and retinal haemorrhages) and assaults showed a high PPV for CM (pooled PPVs: 55.9%-87.8%). Indicators of IPV in women had a high PPV, with primary diagnoses correctly identifying IPV in >85% of cases.

CONCLUSIONS

Coded indicators in EHRs have a high likelihood of correctly classifying types of CM and IPV across the life course, providing a useful tool for assessment, support and monitoring of high-risk groups in health services and research.

Recording Risk Factors of Physical Abuse in Children Younger Than 36 Months With Bone Fractures: A 12-Years Retrospective Study in an Italian General Hospital Emergency Room

Skeletal fractures (SFs) are very common in pediatrics. In some cases, they are secondary to child abuse. Differentiation of accidental from non-accidental fractures (NAFs) is essential as in abused children risk of further injuries leading to severe clinical problems and death is significant. Main objectives of this study were to evaluate the characteristics of SFs of children ≤3 years of age presenting to the Emergency Room (ER) of a Children's Teaching Hospital over a 12-year period and the attention paid by ER physicians to the identification of the indicators that increase suspicion of NAF and that suggest referring of the patient to the child protection agencies. This is a descriptive, retrospective study of the medical records of all the pediatric patients ≤ 36 months of age admitted to the ER of the Azienda Ospedaliera Santa Maria della Misericordia, University of Perugia, Perugia, Italy, for radiological documented SFs between January 1, 2004, and March 31, 2016. Available information was used to evaluate whether indicators of possible child abuse were documented by the ER staff and whether diagnosis of potential abuse was followed by further screening or referral to child protection agencies. During the study period, 11,136 accesses of the ER by children younger than 36 months were documented, among whom 417 presented long bone or skull fractures. Skull fractures were significantly more common among children <12 months of age (p = 0.001), whereas radius/ulna and humerus fractures were diagnosed significantly more frequently in children 12-36 months of age (p = 0.036 and p = 0.022, respectively). Recorded medical history was considered inadequate in 255 (61.2%) cases with no difference related to patient's age. Our study showed that the majority of charts in case of SFs were found to contain inadequate documentation to explain causes at the heart of the fractures and, therefore, to rule out any inflicted trauma. The development of specific referral guidelines, along with the continuous education and training of health professionals, as well as the preparation of structured medical forms, are essential measures to activate in order to improve the referral of children from the ER to child protection agencies.

Understanding forearm fractures in young children: Abuse or not abuse?

This retrospective study describes the characteristics and mechanisms of forearm fractures in children <18 months adding to the evidence-base about forearm fractures. It also examines which features of forearm fractures in young children may help discriminate between abusive and noninflicted injuries. Electronic medical records were reviewed for eligible patients evaluated between September 1, 2007 and January 1, 2012 at two children's hospitals in Chicago, IL. The main outcome measures were the type of fracture and the etiology of the fracture (abuse versus not abuse). The 135 included patients sustained 216 forearm fractures. Most were buckle (57%) or transverse (26%). Child protection teams evaluated 47 (35%) of the patients and diagnosed 11 (23%) as having fractures caused by abuse. Children with abusive versus non-inflicted injuries had significant differences in age (median age 7 versus 12 months), race, and presence of additional injuries. Children with abusive forearm fractures often presented without an explanation or a changing history for the injury. Children with non-inflicted forearm fractures often presented after a fall. No particular type of forearm fracture was specific for child abuse. Any forearm fracture in a young child should be evaluated with special attention to the details of the history and the presence of other injuries. Young age, additional injuries, and an absent or inconsistent explanation should increase concern that the fracture was caused by child abuse.

Child Abuse and Neglect

It is important for surgeons to be able to accurately assess and diagnose child abuse. While they are generally not the only medical professionals involved in the care of children with suspected abuse, they are highly regarded by hospital and social service staff, and their input regarding the cause of injury is unlikely to be ignored. Appropriate diagnosis of abusive injury can prevent future morbidity and mortality in these vulnerable patients, and can also reduce the trauma to families from false accusations of abuse. A sensitive and open-ended history, thorough physical examination, appropriate diagnostic workup with consideration of child abuse as an underlying cause, appropriate documentation of findings, and determination of safety for discharge can greatly improve an abused child's current and future health and safety.

ELECTRICA: ELEctronic knowledge base for Clinical care, Teaching and Research In Child Abuse

Child abuse is a highly significant public health issue with 4-16% of children being physically abused. The diagnosis is sensitive and challenging, with many radiologists dissatisfied with current levels of training and support. The literature shows a lack of prospective scientific research in this complex field. An ELEctronic knowledge base for Clinical care, Teaching and Research In Child Abuse (ELECTRICA) should solve many current problems. ELECTRICA will be populated with clinical information, radiographs and radiographic findings in children younger than 3 years of age presenting with injury (accidental or suspected abuse), to form a unique resource. This web-based tool will unify the investigative protocol in suspected abuse and support training and allow multicentre national and international collaborative research and provide robust evidence to support the legal process.

Outcome of distal tibial physeal injuries

In a retrospective review of 725 children's tibial fractures between 1990 and 2004, we found paediatric tibial fractures to have a bimodal distribution according to age, peaking at the age 14 years with incidence of 17.1 in 1000 in boys and 5.1 in 1000 in girls. Two hundred and twenty-five (31.0%) cases involved the distal tibial physis, associated with Salter-Harris (SH) I (0.4%), SH II (56.9%), SH III (21.7%) and SH IV (20%) injury patterns. Of these fractures, 77% had initial displacement of more than 2 mm and independent of treatment modality, 20% of cases still had residual displacement of more than 2 mm after reduction. There was significantly less residual displacement in patients who had a computed tomography scan before the intervention versus those who did not (0.3 vs. 1.4 mm, P=0.003). Twelve cases (11.2%) of premature physeal closure were identified after SH II (67%), SH III (17%) and SH IV (17%) fractures. No significant link was found between premature physeal closure and displacement (either initial or residual), mechanism of injury, or treatment modality. In those fractures with an intact fibula, we found significantly less initial displacement (4.7 vs. 7.4 mm, P<0.05) and significantly shorter time to union (6.27 vs. 7.55 weeks, P=0.001). Good anatomical reduction with or without open reduction and internal fixation is one of the important factors in reducing complication rates, and we suggest but cannot statistically prove that open reduction and internal fixation is indicated in fractures with a residual displacement of 2 mm or more. The presence of an intact fibula at the time of tibial fracture has a significant positive influence on fracture outcome. Level III: Retrospective Review.
