Pediatric falls from heights

Falls from height in children: epidemiology and outcome

INTRODUCTION

Childhood injury is one of the leading causes of death globally, with falls being the sixth leading cause. This study aimed to examine the demographics, patterns of injury and temporal risk factors for falls from height above 3 m in Singapore.

METHODS

This is a retrospective study conducted on patients who presented after a fall to a paediatric emergency department at a tertiary hospital between January 2011 and July 2017. Electronic medical records were reviewed to extract demographics and data on the patterns of injuries. Criteria for inclusion were patients under 18 years of age and the occurrence of fall from a height of 3 m or above.

RESULTS

A total of 149 children met the inclusion criteria. The median age was 10 years and 69.1% were boys. Death occurred in two (1.3%) cases; 84 (56.4%) were admitted and survived. Of those admitted, five (3.4%) required care in the intensive care unit and 11 (7.4%) required surgery. Falls occurred mostly at homes or residential buildings (n = 59, 39.6%). The two cases of mortality were due to falls from windows at homes. Twenty (33.9%) children fell from windows at homes, with two requiring admission to the intensive care unit.

CONCLUSION

Our study shows that falls from windows of homes are an important cause of mortality. Height of fall was also an important predictor of morbidity that led to a higher level of hospitalisation care. Preventive measures should be implemented to ensure safety in high-rise residential buildings to prevent paediatric falls from heights.

Epidemiology and injury morphology of traumatic hip dislocations in children and adolescents in Germany: a multi-centre study

OBJECTIVE

Traumatic hip dislocations are very rare in childhood and adolescence. The aim of this multi-centre study is to analyse the current epidemiology and injury morphology of a large number of traumatic hip dislocations in children. This can provide a better understanding of childhood hip dislocations and contribute to the development of a therapeutic approach in order to prevent long-term impacts.

METHODOLOGY

This retrospective, anonymised multi-centre study included patients, aged up to 17 years, with acute traumatic hip dislocations and open growth plates. The patients came from 16 German hospitals. Exclusion criteria included insufficient data, a positive history of hip dysplasia, or an association with syndromal, neurological or connective tissue diseases predisposing to hip dislocation. An analysis was carried out on the patients' anthropometric data and scans (X-ray, MRI, CT), which were collected between 1979 and 2021. Gender, age at the time of dislocation, associated fractures, mechanism of injury, initial treatment including time between dislocation and reduction, method of reduction, treatment algorithm following reduction and all documented complications and concomitant injuries were evaluated.

RESULTS

Seventy-six patients met the inclusion criteria. There were two age peaks at 4-8 years and 11-15 years. There was an increased incidence of girls in the under-eight age group, who had mild trauma, and in the group of over-eights there were more boys, who had moderate and severe trauma. Dorsal dislocation occurred in 89.9% of cases. Mono-injuries dominated across all age groups. Concomitant injuries rarely occurred before the age of eight; however, they increased with increasing ossification of the acetabulum and appeared as avulsion injuries in 32% of 11-15-year-olds. Of the 76 patients, 4 underwent a spontaneous, 67 a closed and 5 a primary open reduction. A reduction was performed within 6 h on 84% of the children; however, in around 10% of cases a reduction was not performed until after 24 h. Concomitant injuries needing intervention were identified in 34 children following reduction. Complications included nerve irritation in the form of sensitivity disorders (n = 6) as well as avascular necrosis (AVN) of the femoral head in 15.8% of the patients (n = 12).

CONCLUSIONS

Traumatic hip dislocations are rare in childhood and adolescence and have high complication rates. The most severe complication, femoral head necrosis, occurred in 16% of cases. Minor injuries, especially in younger children, are enough to cause a dislocation. Posterior dislocation was more frequent and primarily occurred as a mono-injury; however, concomitant injuries must be considered with increasing age. Children continue to experience delayed reductions. The length of time until reduction, age and the severity of the concomitant injury play a role in the development of femoral head necrosis; however, this topic requires additional investigation.

Traumatic Hip Dislocation in Pediatric Patients: Clinical Case Series and a Narrative Review of the Literature with an Emphasis on Primary and Long-Term Complications

Traumatic hip dislocation is a rare injury in pediatric populations. Dislocation may be associated with low-energy trauma, such as a minor fall. Traumatic hip dislocation is associated with severe complications, such as avascular necrosis of the femoral head. Timely diagnosis and reposition decrease the rate of complications. In this study we retrospectively assessed traumatic hip dislocations in pediatric patients during a 10-year timespan in a university hospital. There were eight cases of traumatic hip dislocations. All patients had a minimum follow-up of two years and were followed with MRI scans. One patient developed avascular necrosis during the follow-up which resolved conservatively. There were no other significant complications. In conclusion, traumatic hip dislocation is a rare injury which is associated with severe complications. Patients in our case series underwent a timely reposition. The complication rate was similar to previous reports.

Evaluation of forensic fall from height cases aged two years and younger

Purpose: Childhood trauma is often caused by accidental or neglected falls. In this study, we aimed to evaluate demographic and clinical factors to determine the incidence of falls from height in children under two years old. Materials and Methods: The study included 106 forensic cases who presented to the emergency department after falling from a height of one meter or more as a result of an accident or negligence between January 1, 2016 and December 31, 2021. According to the level of fall height, the cases were divided into two groups as below 3 meters and above. Clinical findings, hospitalization, and mortality status were used to group patients. Results:Of the 106 cases included in the study, 59(55.7%) were male.The mean age of the patients was 12.89±6.80 months (p=0.002) and the mean height level was 3.67±2.85 m (p=0.001).The mean height of the Low and High groups was 1.78±0.71, 6.92±2.09 meters, respectively.Crainal fracture was present in 21(19.8%) patients in the high group and all traumatic parenchymal brain lesions except contusion were seen in the high group (p=0.001). Four (3.8 %) of the 9(8.5%) dead cases died in emergency department. The average height of emergency department fall victims was 9.75±2.63 meters (p=0.001). Conclusion: Especially cases of falling from height under the age of two are common and are an important cause of morbidity and mortality. Fall height level is an important marker in terms of clinical and prognosis. Informing and educating caregivers and parents can prevent accidents and neglect in advance.

Accuracy of Height Estimation Among Bystanders

INTRODUCTION

High-risk mechanisms in trauma usually dictate certain treatment and evaluation in protocolized care. A 10-15 feet (ft) fall is traditionally cited as an example of a high-risk mechanism, triggering trauma team activations and costly work-ups. The height and other details of mechanism are usually reported by lay bystanders or prehospital personnel. This small observational study was designed to evaluate how accurate or inaccurate height estimation may be among typical bystanders.

METHODS

This was a blinded, prospective study conducted on the grounds of a community hospital. Four panels with lines corresponding to varying heights from 1-25 ft were hung within a building structure that did not have stories or other possibly confounding factors by which to judge height. The participants were asked to estimate the height of each line using a multiple-choice survey-style ballot. Participants were adult volunteers composed of various hospital and non-hospital affiliated persons, of varying ages and genders. In total, there were 96 respondents.

RESULTS

For heights equal to or greater than 15 ft, less than 50% of participants of each job description were able to correctly identify the height. When arranged into a scatter plot, as height increased, the likelihood to underestimate the correct height was evident, having a strong correlation coefficient (R=+0.926) with a statistically significant p value = <0.001.

CONCLUSION

The use of vertical height as a predictor of injury severity is part of current practice in trauma triage. This data is often an estimation provided by prehospital personnel or bystanders. Our small study showed bystanders may not estimate heights accurately in the field. The greater the reported height, the less likely it is to be accurate. Additionally, there is a higher likelihood that falls from greater than 15 ft may be underestimated.

Traumatic fractures as a result of falls in children and adolescents: A retrospective observational study

The aim of this study is to investigate the incidence and pattern of traumatic fractures (TFs) as a result of falls in a population of children and adolescents (≤18 years old) in China.This was a cross-sectional study. We retrospectively reviewed 1412 patients who were children and adolescents with TFs as a result of falls admitted to our university-affiliated hospitals in China from 2001 to 2010. Etiologies included high fall (height ≥2) and low fall (height <2 m). The incidence and pattern were summarized with respect to different age groups, year of admission, etiologies, genders, and the neurological function.This study enrolled 1054 males (74.6%) and 358 females (25.4%) aged 10.8 ± 4.7 years. The etiologies were low fall (1059, 75.0%) and high fall (353, 25.0%). There were 2073 fractures in total and 92 patients (6.5%) presented with multiple fractures. The most common fracture sites were upper extremity fractures in 814 patients (57.6%) and lower extremity fractures in 383 patients (27.1%), followed by craniofacial fractures in 233 patients (16.5%). A total of 231 (16.4%) patients suffered a nerve injury. The frequencies of early and late complications/associated injuries were 19.5% (n = 275) and 9.2% (n = 130). The frequencies of emergency admission, nerve injury, spinal fracture, lower extremity fractures, craniofacial fracture, sternum and rib fracture, and early complications/ASOIs were significantly larger in high fall than low fall (all P <.001, respectively). The frequencies of medical insurance rate (P = .042) and upper extremity fractures (P <.001) were significantly larger in low fall than high fall. The frequencies of spinal fracture (P = .039), lower extremity fractures (P = .048), and craniofacial fracture (P = .041) were significantly larger in female than the male patients. The frequency of upper extremity fractures (P <.001) and the mean age (P <.001) was significantly larger in male than female patients. The frequencies of emergency admission, high fall, spinal fracture, and craniofacial fracture were significantly larger in patients with nerve injury than other patients without nerve injury (all P <.001, respectively).Low falls and upper extremity fractures were the most common etiologies and sites, respectively. High fall, spinal fracture and craniofacial fracture were risk factors for nerve injury. Therefore, we should focus on patients who were caused by high fall and presented with spinal and craniofacial fracture to determine the presence of a nerve injury so that we can provide early, timely diagnosis and targeted treatment to children.

Severe cranial neuropathies caused by falls from heights in children

PURPOSE

Falls from heights are the most common traumatic event associated with emergency department visits in children. This study investigated the incidence and clinical course of cranial neuropathies caused by falls from heights in children.

METHODS

The computerized records of a tertiary pediatric medical center were searched for all patients admitted to the emergency department in 2004-2014 with a head injury caused by falling from a height. Those with cranial neuropathies involving optic and eye-motility disturbances were identified, and their clinical, imaging, and outcome data were evaluated.

RESULTS

Of the estimated 61,968 patients who presented to the emergency department during the study period because of a fall, 18,758 (30.3 %) had head trauma. Only 12 (seven boys, five girls, average age 6.7 years) had a visual disturbance. Eight were diagnosed with traumatic optic neuropathy, one after a 6-month delay, including two with accompanying cranial nerve (CN) III injuries. Five patients had anisocoria or an abnormal pupillary response to light at presentation, one patient had CN VI paralysis and temporary vision loss, and one patient had an isolated CN III injury diagnosed on follow-up. Visual improvement varied among the patients.

CONCLUSION

Cranial neuropathies due to falls from heights are rare in children and are associated with high visual morbidity. Vision or ocular motility impairment, especially monocular vision loss, may be missed during acute intake to the emergency department, and a high index of suspicion is needed. Assessment of the pupillary response to light is essential.

Outcome of traumatic hip dislocation in children

We reviewed 13 patients without an underlying syndrome with traumatic hip dislocation between 3 and 10 years of age (mean 4.8 years) at the time of injury. The final reviews were between 1 and 11 years (mean 6 years). All children had posterior dislocation, except one, who had an anterior dislocation. Time taken from trauma to reduction was less than 6 h in three patients, 6 h to 1 day in two patients, 1 day to 3 weeks in seven patients, and 4 weeks in one. All of them underwent closed reduction, except two, who required open reduction through a posterior approach. All patients had excellent hip function and radiographic result on the basis of Garret classification, except for one with limping at 4 years after trauma. The patients treated with hip spica after reduction (10 patients) did not have recurrent dislocation whereas two out of three patients who were treated without postreduction hip spica developed recurrent dislocation. One out of 13 patients without an underlying syndrome and a 6-year-old patient with Down syndrome with neglected hip dislocation and radiological avascular necrosis at presentation recovered with congruent hip following a complete and maintained reduction. This case series suggested that closed reduction was possible for cases of neglected hip dislocation for up to 3 weeks. Open reduction through the posterior approach was safe in neglected irreducible posterior hip dislocation. Those hips that underwent complete reduction and were maintained reduced with hip spica had an excellent functional outcome even in the presence of avascular necrosis. This is a level IV study.

Finite element model predictions of intracranial hemorrhage from non-impact, rapid head rotations in the piglet

Clinicians are charged with the significant task of distinguishing between accidental and inflicted head trauma. Oftentimes this distinction is straightforward, but many times probabilities of injuries from accidental scenarios are unknown making the differential diagnosis difficult. For example, it is unknown whether intracranial hemorrhage (IH) can occur at a location other than a focal contact site following a low height fall. To create a foundation for predicting regional IH in infants, we sought to identify the biomechanical response and injury threshold best able to predict IH in 3-5 day old piglets. First, finite element (FE) model simulations of in situ animal studies were performed to ascertain the optimal representation of the pia-arachnoid complex, cerebrospinal fluid and cortical vasculature (PCC) for predicting brain strain and brain/skull displacement. Second, rapid head rotations resulting in various degrees of IH were simulated (n=24) to determine the biomechanical predictor and injury threshold most closely correlated with IH. FE models representing the PCC with either spring connectors or solid elements between the brain and skull resulted in peak brain strain and brain/skull displacement similar to measured values in situ. However, when predicting IH, the spring connector representation of the PCC had the best predictive capability for IH with a sensitivity of 80% and a specificity of 85% when ≥ 1% of all spring connectors had at least a peak strain of 0.31 mm/mm. These findings and reported methodology will be used in the development of a human infant FE model to simulate real-world falls and identify injury thresholds for predicting IH in infants.

Pediatric injuries attributable to falls from windows in the United States in 1990-2008

OBJECTIVE

To examine the epidemiological features of pediatric injuries related to falls from windows.

METHODS

By using the National Electronic Injury Surveillance System, emergency department (ED) data for pediatric injury cases associated with window falls in 1990-2008 were reviewed.

RESULTS

An estimated 98 415 children (95% confidence interval [CI]: 82 416-114 419) were treated in US hospital EDs for window fall-related injuries during the 19-year study period (average: 5180 patients per year [95% CI: 4828-5531]). The mean age of children was 5.1 years, and boys accounted for 58.1% of cases. One-fourth (25.4%) of the patients required admission to the hospital. The annual injury rate decreased significantly during the study period because of a decrease in the annual injury rate among 0- to 4-year-old children. Children 0 to 4 years of age were more likely to sustain head injuries (injury proportion ratio [IPR]: 3.22 [95% CI: 2.65-3.91]) and to be hospitalized or to die (IPR: 1.65 [95% CI: 1.38-1.97]) compared with children 5 to 17 years of age. Children who landed on hard surfaces were more likely to sustain head injuries (IPR: 2.05 [95% CI: 1.53-2.74]) and to be hospitalized or to die (IPR: 2.23 [95% CI: 1.57-3.17]) compared with children who landed on cushioning surfaces.

CONCLUSIONS

To our knowledge, this is the first study to investigate window fall-related injuries treated in US hospital EDs by using a nationally representative sample. These injuries are an important pediatric public health problem, and increased prevention efforts are needed, including development and evaluation of innovative prevention programs.

Epidemiology of balcony fall-related injuries, United States, 1990-2006

BACKGROUND

Falls from heights are common in urban areas in the United States. This study describes the epidemiology of balcony fall-related injuries requiring emergency department (ED) treatment among children and adults in the United States from 1990 through 2006.

METHODS

In 2009, a retrospective analysis of data from the National Electronic Injury Surveillance System of the US Consumer Product Safety Commission was conducted to describe the epidemiology of balcony fall-related injuries.

RESULTS

An estimated 86,500 (95% confidence interval [CI], 68,400-104,600) balcony fall-related injuries were treated in US hospital EDs from 1990 through 2006; 70% of cases were male; 63% were adults (≥18 years old); 94% of injury events occurred at home; 24% of patients were hospitalized; and 8 patients died. The rate of balcony fall-related injuries among children decreased significantly during 1990 to 2006 and was similar to that of adults by the end of the study period. Fall heights ranged from 5 to 87.5 ft. Structural failure of the balcony was involved in an estimated 5600 cases. Patients younger than 18 years were more likely to sustain a concussion/closed head injury (relative risk, 2.42; 95% CI, 1.84-3.18) or skull fracture (relative risk, 5.86; 95% CI, 2.58-13.30) than adults.

CONCLUSIONS

This is the first study of balcony fall-related injuries requiring emergency treatment using a nationally representative sample. Balcony falls are an important cause of injury in the United States. Age, male sex, and warm months of the year were associated with balcony fall-related injuries in our study population.

Pediatric tree house-related injuries treated in emergency departments in the United States: 1990-2006

OBJECTIVES

The objective was to describe the epidemiology of tree house-related injuries in the United States among children and adolescents.

METHODS

The authors conducted a retrospective analysis using data from the National Electronic Injury Surveillance System for patients < or =19 years who were treated in an emergency department (ED) for a tree house-related injury from 1990 through 2006.

RESULTS

An estimated 47,351 patients < or =19 years of age were treated in EDs for tree house-related injuries over the 17-year study period. Fractures were the most common diagnosis (36.6%), and the upper extremities were the most commonly injured body part (38.8%). The odds of sustaining a head injury were increased for children aged <5 years. Falls were the most common injury mechanism (78.6%) and increased the odds of sustaining a fracture. Falls or jumps from a height > or =10 feet occurred in 29.3% of cases for which height of the fall/jump was recorded. Boys had significantly higher odds of falling or jumping from a height of > or =10 ft than girls, and children 10 to 19 years old also had significantly higher odds of falling or jumping from a height of > or =10 feet, compared to those 9 years old and younger. The odds of hospitalization were tripled if the patient fell or jumped from > or =10 feet and nearly tripled if the patient sustained a fracture.

CONCLUSIONS

This study examined tree house-related injuries on a national level. Tree house safety deserves special attention because of the potential for serious injury or death due to falls from great heights, as well as the absence of national or regional safety standards. The authors provide safety and prevention recommendations based on the successful standards developed for playground equipment.

Accidental traumatic head injury in infants and young children

This article will discuss accidental head injuries in infants and young children. The first category of injury is the crushing head injury. Static forces applied slowly to the head result in multiple fractures of the skull and contusions and lacerations of the brain resulting from the bone fragments striking the brain. This article will discuss the subject of short falls in young children and the resulting head injuries. Because falls are frequent events in early life, many cases have been collected and many papers written on the subject. Study of these cases is informative about the injuries likely to occur in these falls. Most often, only a minor contact injury such as scalp bruise or laceration results. In a 2 to 3% of falls, a simple linear skull fracture occurs and the majority of these are uneventful in terms of neurological deficit or intracranial bleeding. In about 1% of the fractures, an epidural or subdural hemorrhage occurs. Each of these forms of contact hemorrhages will be discussed and illustrated. While these are relatively rare injuries, it is essential that they can be identified as consistent with an accidental mechanism so that an erroneous diagnosis of inflicted injury is not made.

Annual risk of death resulting from short falls among young children: less than 1 in 1 million

OBJECTIVE

The objective of the work was to develop an estimate of the risk of death resulting from short falls of <1.5 m in vertical height, affecting infants and young children between birth and the fifth birthday.

METHODS

A review of published materials, including 5 book chapters, 2 medical society statements, 7 major literature reviews, 3 public injury databases, and 177 peer-reviewed, published articles indexed in the National Library of Medicine, was performed.

RESULTS

The California Epidemiology and Prevention for Injury Control Branch injury database yielded 6 possible fall-related fatalities of young children in a population of 2.5 million young children over a 5-year period. The other databases and the literature review produced no data that would indicate a higher short-fall mortality rate. Most publications that discuss the risk of death resulting from short falls say that such deaths are rare. No deaths resulting from falls have been reliably reported from day care centers.

CONCLUSIONS

The best current estimate of the mortality rate for short falls affecting infants and young children is <0.48 deaths per 1 million young children per year. Additional research is suggested.

Childhood falls: characteristics, outcome, and comparison of the Injury Severity Score and New Injury Severity Score

OBJECTIVES

The aim of this study was to determine the general characteristics of childhood falls, factors affecting on mortality, and to compare the Injury Severity Score (ISS) and the New Injury Severity Score (NISS) as predictors of mortality and length of hospital stay in childhood falls.

METHODS

We retrospectively analysed over a period of 8 years children aged younger than14 years who had sustained falls and who were admitted to our emergency department. Data on the patients' age, sex, type of fall, height fallen, arrival type, type of injuries, scoring systems, and outcome were investigated retrospectively. The ISS and NISS were calculated for each patient. Comparisons between ISS and NISS for prediction of mortality were made by receiver operating characteristic (ROC) curve and Hosmer-Lemeshow (HL) goodness of fit statistics.

RESULTS

In total, there were 2061 paediatric trauma patients. Falls comprised 36 (n = 749) of these admissions. There were 479 male and 270 female patients. The mean (SD) age was 5.01 (3.48) years, and height fallen was 3.8 (3) metres. Over half (56.6%) of patients were referred by other centres. The most common type of fall was from balconies (38.5%), and head trauma was the most common injury (50%). The overall mortality rate was 3.6%. The cut off value for both the ISS and NISS in predicting mortality was 22 (sensitivity 90.5%, specificity 95.4% for ISS; sensitivity 100%, specificity 88.7% for NISS) (p>0.05). Significant factors affecting mortality in logistic regression analysis were Glasgow Coma Scale (GCS) <9, ISS >22, and NISS >22. There were no significant differences in ROC between three scoring systems. The HL statistic showed poorer calibration (p = 0.02 v p = 0.37, respectively) of the NISS compared with the ISS.

CONCLUSIONS

In our series, the head was the most frequent site of injury, and the most common type of fall was from balconies. Scores on the GCS, NISS, and ISS are significantly associated with mortality. The performance of the NISS and ISS in predicting mortality in childhood falls was similar.

Pediatric window falls: not just a problem for children in high rises

BACKGROUND

Window falls are a frequent cause of injury (15/100,000) among Chicago preschool children. In Boston and New York, public health efforts have successfully decreased window fall injuries. Local data are needed to develop appropriate interventions for Chicago.

OBJECTIVE

To describe the housing characteristics and types of injuries among children who fell from windows treated in a Chicago pediatric trauma center.

METHODS

Children treated in a pediatric trauma center for injuries related to window falls between 1995 and 2002 were identified retrospectively. We reviewed family demographics, the circumstances of the fall, and types of injuries. Site visits were performed to determine the height and type of building and type of window where the fall took place.

RESULTS

The authors reviewed 90 cases; 55 were male. The median age was 2 years. Ninety eight percent of falls were reported to be from the third floor or lower. Site visits (n=77) showed that 96% of the buildings were four storeys or lower. The median length of hospital stay was two days (range 0--24 days). The most common injuries were head trauma and extremity fractures. Three patients died, and an additional three patients were discharged to rehabilitation centers.

CONCLUSIONS

Some window falls result in serious injury. In Chicago, most falls were from modest heights (2nd/3rd floor windows) in buildings of four or fewer storeys, rather than from "high rises". Strategies to prevent window falls should be directed to the owners and occupants of this type of housing.

Child and adolescent injury as a result of falls from buildings and structures

OBJECTIVE

To examine incidence, demographic risk factors, and patterns of injury resulting from falls from buildings and structures in areas with and without a legislation based prevention programme.

DESIGN AND SETTING

The Health Care Cost and Utilization Project (KID-HCUP) was used to produce national estimates of hospital admissions due to falls from buildings in the US. Areas of New York with and without window guard legislation were identified through the New York Statewide Planning and Research Cooperative System (SPARCS).

SUBJECTS

Children and adolescents aged 0-18 years.

INTERVENTIONS

Legislation based window fall prevention programme with enforcement.

MAIN OUTCOME MEASURES

Hospitalization for injury as a result of falls from buildings and structures in areas with and without enforced mandatory window guard legislation.

RESULTS

New York City has a higher proportion of the population residing in multi-family dwellings with 10 or more units compared with the nation (53.8% v 12.6%, p<0.0001), but the incidence of injury resulting from falls from buildings is nearly half that observed in the US. For young children, warm weather risks begin earlier and extend later than previously reported. Incidence in very young minority children is nearly twice that of whites. Nearly 90% of children aged 0--4 years fall at home, but the proportion decreases linearly with age.

CONCLUSIONS

Window guards are associated with reduced injury resulting from falls from buildings and should be mandated in multi-family dwellings where small children reside. Prevention programmes for young children should be initiated in early spring and continued through fall.

Childhood injuries due to falls from apartment balconies and windows

BACKGROUND

Falls from balconies and windows are an important cause of childhood injury. This study investigated the circumstances around such falls and attempted to identify possible measures for their prevention.

POPULATION

Children <15 years living in Dallas County, Texas.

METHODS

Each child treated because of a fall from a building in 1997-99 had information about the injury collected, and a parent was contacted to obtain further information. For apartment related falls, an attempt was made to visit the apartment to measure windows and balcony rails.

RESULTS

Ninety eight children were injured in falls from buildings during the three year period; 39 (40%) were admitted to hospital. Seventy five of the falls (77%) involved apartments, and most occurred around noon or evening meal times. Among apartment falls, 39 (52%) fell from windows, 34 (45%) from balconies, and two (3%) from unknown sites. For more than two thirds of balcony related falls, the child fell from between the balcony rails, all of which were spaced more than 4 inches (10 cm) apart. On-site measurement showed the rails were an average of 7.5 inches (19 cm) apart; all of these apartments were built before 1984. For more than two thirds of window related falls, the window was situated within 2 feet (61 cm) of the floor.

CONCLUSIONS

Two factors are important in falls from apartment windows and balconies: balcony rails more than 4 inches (10 cm) apart, and windows positioned low to the floor. Current building codes do not apply to older apartments, where most of these falls occurred. Nevertheless, these factors may be amenable to environmental modifications that may prevent most of these falls.

Anthropomorphic simulations of falls, shakes, and inflicted impacts in infants

OBJECT

Rotational loading conditions have been shown to produce subdural hemorrhage and diffuse axonal injury. No experimental data are available with which to compare the rotational response of the head of an infant during accidental and inflicted head injuries. The authors sought to compare rotational deceleration sustained by the head among free falls, from different heights onto different surfaces, with those sustained during shaking and inflicted impact.

METHODS

An anthropomorphic surrogate of a 1.5-month-old human infant was constructed and used to simulate falls from 0.3 m (1 ft), 0.9 m (3 ft), and 1.5 m (5 ft), as well as vigorous shaking and inflicted head impact. During falls, the surrogate experienced occipital contact against a concrete surface, carpet pad, or foam mattress. For shakes, investigators repeatedly shook the surrogate in an anteroposterior plane; inflicted impact was defined as the terminal portion of a vigorous shake, in which the surrogate's occiput made contact with a rigid or padded surface. Rotational velocity was recorded directly and the maximum (peak-peak) change in angular velocity (delta theta(max)) and the peak angular acceleration (theta(max)) were calculated. Analysis of variance revealed significant increases in the delta theta(max) and theta(max) associated with falls onto harder surfaces and from higher heights. During inflicted impacts against rigid surfaces, the delta theta(max) and theta(max) were significantly greater than those measured under all other conditions.

CONCLUSIONS

Vigorous shakes of this infant model produced rotational responses similar to those resulting from minor falls, but inflicted impacts produced responses that were significantly higher than even a 1.5-m fall onto concrete. Because larger accelerations are associated with an increasing likelihood of injury, the findings indicate that inflicted impacts against hard surfaces are more likely to be associated with inertial brain injuries than falls from a height less than 1.5 m or from shaking.

Jumpers and fallers: a comparison of the distribution of skeletal injury

AIM

The aim of this study was to compare the distribution of injuries between patients who have fallen and those who have jumped from a height, and to relate the mechanism of injury to the fractures sustained.

MATERIALS AND METHODS

Three hundred and ninety-nine patients, admitted via Helicopter Emergency Medical Service (HEMS), classified as either having fallen or jumped from a height were included in the study. The radiographs from the primary survey, together with radiographs of specific injury sites were analysed. The distribution of injury was compared in the two groups.

RESULTS

Of the 399 patients, 342 were fallers and 57 were jumpers. Jumpers had a higher Injury Severity Score (ISS), death rate and number of fractures per person. Jumpers sustained more rib fractures (particularly on the right), pelvic and lower limb fractures but fewer skull fractures.

CONCLUSION

Jumpers tend to sustain different injuries to fallers. It is proposed that jumpers have a tendency to land feet-first and then try to break their falls on their dominant side, sustaining more right-sided rib fractures in the process. The patterns of injury that have emerged from this study have important implications for evaluating skeletal injuries in those who jump or fall from a height.

Pelvic fractures in infants as a sign of physical abuse

OBJECTIVE

The purpose of this article is to describe pelvic fractures in two abused male infants, and to determine if the literature describes pelvic fractures in infants as suspicious for child physical abuse.

RESULTS

Two infants are described with unexplained pelvic fractures. While in one case child abuse was obvious, careful attention to the radiological evaluation and case history led to the correct diagnosis of child abuse in the second case. A search for information regarding pelvic fractures in children resulted in information limited to the radiological and surgical literature.

CONCLUSIONS

Medical providers frequently encounter children with fractures suspicious for child abuse. The most common fractures seen in abused children are metaphyseal, rib, skull, and long bone fractures. This report illustrates that pelvic fractures occurring in the absence of serious, well documented accidents should be considered highly suspicious for child physical abuse.

The cause of infant and toddler subdural hemorrhage: a prospective study

OBJECTIVE

To determine the frequency of child abuse and unintentional injury as a cause of infant and toddler subdural hemorrhage (SDH).

METHODS

A prospective case series of a level I regional trauma center, regional children's hospital, and county medical examiner's office assessed consecutive children who were </=36 months old and had SDH. Children who had previously known hemorrhagic disease, previous neurosurgical procedure, previously recognized perinatal brain injury, meningitis, renal dialysis, and severe dehydration were excluded. Concurrent medical, retinal, skeletal, and social work abuse evaluation were measured. Etiologic assessment using predetermined criteria was conducted.

RESULTS

From March 1995 through December 1998, 66 children were admitted with SDH. Abuse was confirmed in 39 (59%), unintentional injury in 15 (23%), and indeterminate cause in 12 (18%). The mean age of abused children was 8.7 +/- 8.1 months and of children with unintentional injuries was 19.1 +/- 10.0 months. The predominant presenting histories for abusive injury were a minor fall or no mechanism for 33 (84%) of 39 patients. All unintentional injuries resulted from a motor vehicle accident or other documented major trauma. Chronic or mixed acute and chronic SDH were found only in abused children (17 [44%] of 39) and in children whose injuries were indeterminate (8 [67%] of 12), not in children who were unintentionally injured (0 [0%] of 15). Long bone and/or rib fractures were found in 20 (51%) of 39 abused children but in only 1 unintentionally injured child. Retinal bleeding was present in 28 (72%) of 39 of the abused children. Only 1 of the 3 unintentionally injured children who had a retinal examination had bleeding, which was of the type associated with acute increased intracranial pressure.

CONCLUSIONS

Nearly one fifth of infant and toddler SDH resulted from unintentional trauma. Of those without obvious unintentional trauma, 76% were corroborated to have been abused. Abused children were younger, more likely to have chronic SDH, and more likely to have multiple associated injuries. Their injury history usually was minor or absent.

American Academy of Pediatrics: Falls from heights: windows, roofs, and balconies

Falls of all kinds represent an important cause of child injury and death. In the United States, approximately 140 deaths from falls occur annually in children younger than 15 years. Three million children require emergency department care for fall-related injuries. This policy statement examines the epidemiology of falls from heights and recommends preventive strategies for pediatricians and other child health care professionals. Such strategies involve parent counseling, community programs, building code changes, legislation, and environmental modification, such as the installation of window guards and balcony railings.

Pediatric Falls: Is Height a Predictor of Injury and Outcome?

Falls account for a significant proportion of pediatric injuries and deaths. A retrospective review of pediatric patients (age 0–14 years) was performed to determine whether patterns of injuries and outcomes could be predicted on the basis of the height of the fall. In addition we evaluated the triage criterion “fall greater than 15 feet” for transport of patients to a trauma center. Patients were stratified by the height of the fall: greater than or less than 15 feet. The end points for analysis were the associated injuries and survival. Patients who fell less than 15 feet had a higher incidence of intracranial injuries (and fewer extremity fractures than patients who fell more than 15 feet). Skull fractures were the most frequent injury and were associated with an increase in intracranial injuries in both subgroups. In conclusion low-level falls are associated with significant intracranial injuries. The evaluation of patients sustaining low-level falls should not be limited on the basis of the height of the fall. Using falls of greater than 15 feet as a triage criterion for transport to a trauma center needs to be prospectively evaluated to ensure that critically injured patients are triaged appropriately.

Windows 99: a source of suburban pediatric trauma

BACKGROUND

Falls from windows in urban areas cause a significant number of pediatric injuries. Window falls have not been well described in the nonurban setting. We describe the epidemiology of window falls from residential homes among pediatric patients at a suburban Level I trauma center.

METHODS

A review of patients admitted from January 1991 through November 1999 to a center serving a rapidly growing suburban area was performed.

RESULTS

A total of 2,322 children, ages 0-14 years, were admitted during the study period. Falls comprised 41% of these admissions, and 11% of falls were from windows, greater than twice the national average. More than 39% of children who fell from windows were admitted directly to the intensive care unit. Overall mortality rate was 4%. Ages 0 to 4 years comprised the largest percentage (83%), and all children who died were in this age group. Children < or = 4 years were more likely to have an Abbreviated Injury Score > or = 2 (head injury) than those ages 10 to 14 years (p = 0.032). More than 31% of all children injured in window falls seen at the study institution between 1991 and 1999 were admitted in the last 2 years.

CONCLUSION

Pediatric falls from windows in this suburban area appear to be increasing, with an incidence greater than the national average. Children at greatest risk are less than 4 years old. Further research in injury prevention at the national level aimed at suburban areas may be warranted.

Can falls on stairs result in small intestine perforations?

OBJECTIVE

Abusive parents often report that a fall on stairs resulted in their children's injuries. This review explores whether there is any evidence in the medical literature that a fall on stairs could be a plausible explanation for a small intestine perforation.

METHODOLOGY

The English-language medical literature was searched by Medline, for a 29-year period (1970-1998), for reports of the types of injuries sustained in falls on stairs and for reports of the types of blunt abdominal trauma that result in small intestine perforations. Articles that exclusively focused on infant walker injuries or the elderly were excluded. Duodenal, jejunal, and ileal perforations were included, whereas intestinal hematomas and undescribed intestinal injuries were excluded. All types of injuries to the stomach, colon, and rectum were excluded.

RESULTS

Falls on stairs were not reported to be a cause for any of the 312 cases of small intestine perforations reviewed. There were no reports of any intraabdominal injuries, including small intestine perforations, in any of the 677 cases of falls on stairs reviewed. Falls on stairs rarely resulted in any type of truncal injury.

CONCLUSIONS

Although falls on stairs have been reported to be the most common cause of injury in childhood, no evidence was found to support the contention that an unobstructed fall on stairs could be consistent with perforation of the small intestine.

Childhood injuries and deaths due to falls from windows

BACKGROUND

Unintentional injuries are the leading cause of death in children, and falls are the most common type of unintentional injury in the US. The incidence of falls from windows, a common cause of death in urban areas, has not been described outside major cities such as New York and Chicago, and rates in urban and suburban areas have not been compared.

OBJECTIVE

To estimate the incidence and identify the population at risk for falls from windows among children in Hamilton County, Ohio.

DESIGN

Retrospective case series identified using Cincinnati Children's Hospital Medical Center (CHMC) Trauma Registry.

SETTING

Hamilton County, Ohio, which has urban and nonurban areas.

PARTICIPANTS

Children less than 15 years old residing in Hamilton County, Ohio, presenting to CHMC in Cincinnati, Ohio, after a fall from a window between January 1, 1991, and December 31, 1997.

OUTCOME MEASURE

Annual incidence by age, race, gender, and residence of those who fell from windows.

RESULTS

Over the 7-year study period, 86 (6.3%) of 1,363 falls were from windows. The mortality rate for falls from windows was 4.7%, compared to 0.07% for all other falls presenting to CHMC (P<.0001). Children 0-4 years old had a higher rate of falls than children aged 5-14 (14.6/100,000 vs. 2.0/100,000) (P<.0001). Males were twice as likely to fall as females (P<.016), and black children were three times more likely to fall than non-black children (P<.002). The incidence of falls in the city of Cincinnati was four times that of the non-urban area (P<.0002).

CONCLUSIONS

Injuries from falls from windows are a public health problem in Hamilton County, Ohio, especially for young, urban children.

Early prediction of neurological outcome after falls in children: metabolic and clinical markers

Falls are the foremost reason for non-fatal injuries and are second only to motor vehicle accidents in causing accidental death. The purpose of this study was to identify the clinical and metabolic predictors of the outcome of head injury caused by falls from a height. Medical records of 61 children who had been admitted to the paediatric intensive care unit from 1990 to 1993 after falling from a height were reviewed retrospectively. Outcomes were categorised as good, moderate, severe, and poor. Glasgow coma scores, pupillary responses, brain oedema, and midline shift are significantly associated with poor outcome (p < 0.05). Metabolic markers associated with poor outcome included hyperglycaemia and hypokalaemia. Children with a poor outcome had, at admission, significantly higher glucose concentrations compared with children with good outcomes (mean SD): 20.0 (7.1) v 9.31 (4.0) mmol/l, p < 0.01), and lower potassium concentrations compared with children with good, moderate, and severe outcomes (mean (SD): 2.8 (0.4) v 3.7 (0.4) mmol/l, p < 0.001, 3.5 (0.3) mmol/l, p < 0.01, and 3.41 (0.3) mmol/l, p < 0.05, respectively). These findings allow for an early allocation of effort and resources to children injured from such falls.

Low falls: an underappreciated mechanism of injury

OBJECTIVE

This is a retrospective study designed to evaluate the pattern and severity of injuries that result from low falls, defined as falls from less than 20 ft, subsequent mortality, and requirements of hospital resources. Our hypothesis is that many of these injuries, even without cardiopulmonary instability, are worthy of trauma center care.

METHODS

The records of all patients entered into the hospital trauma registry at an urban Level I trauma center during the years 1991 through 1997 who suffered low falls and who either died after admission or were hospitalized for at least 3 days were reviewed. Patients suffering isolated hip fractures were excluded. One hundred seventy-six patients constituted the study population. This group accounts for about 2% of all admissions for falls at our institution. Patterns of injury were examined. Age, mechanism of injury, Injury Severity Score (ISS), and cardiopulmonary or neurologic instability on admission were documented. Mortality, length of intensive care unit and hospital stays, as well as billed hospital charges, were reviewed.

RESULTS

The majority of patients (62%) were younger than 50 years. Sixty patients had ISS >15 and 116 patients had ISS >9. Sixty patients had multisystem injuries requiring specialty care. Head injuries were found in 81 patients (35%), and vertebral fractures or spinal cord injuries were found in 49 patients (22%), including 9 quadriplegics and 5 paraplegics. There were seven patients with intra-abdominal injuries (five spleen and two bowel injuries). There was one patient with a rupture of the thoracic aorta. Seventeen patients had deteriorating neurologic or pulmonary function on arrival, but the majority (90%) were stable. Of the 159 "stable" patients, 48 suffered head injuries, 7 were quadriplegic, and 3 were paraplegic. All intra-abdominal injuries were in this group. Overall, 14 of 176 patients (8%) died. Seven deaths were in patients older than 60 years, and seven deaths were in younger patients (p = 0.04). The majority of deaths (9 of 14) were from head trauma. Care in the intensive care unit was required in 92 of 176 patients. Nine patients had billed charges exceeding $100,000.

CONCLUSION

Low falls can cause significant injuries, most commonly to the head and spine. Based on mechanism of injury alone, patients injured in low falls might not be taken to trauma centers. We have found, however, that many of these patients sustain serious multisystem injuries, even though they are stable initially. Although these patients represent only a fraction of those who fall, our study would support adjustment of triage guidelines to recommend transport of such patients, particularly elderly patients, to trauma centers.

Neuroimaging, physical, and developmental findings after inflicted and noninflicted traumatic brain injury in young children

OBJECTIVE

To characterize neuroimaging, physical, neurobehavioral, and developmental findings in children with inflicted and noninflicted traumatic brain injury (TBI) and to identify characteristic features of inflicted TBI.

METHODS AND PATIENTS

Forty children, 0 to 6 years of age, hospitalized for TBI who had no documented history of previous brain injury were enrolled in a prospective longitudinal study. TBI was categorized as either inflicted (n = 20) or noninflicted (n = 20) based on the assessment of hospital and county protective services. Glasgow Coma Scale scores and neonatal history were comparable in both groups.

OUTCOME MEASURES

Acute computed tomography/magnetic resonance imaging studies and physical findings were evaluated. Glasgow Outcome Scale scores, cognitive development, and motor functioning were assessed an average of 1.3 months after TBI. chi2 analyses assessed differences in the distribution of findings in the inflicted and noninflicted TBI groups.

RESULTS

Signs of preexisting brain injury, including cerebral atrophy, subdural hygroma, and ex vacuo ventriculomegaly, were present in 45% of children with inflicted TBI and in none of the children with noninflicted TBI. Subdural hematomas and seizures occurred significantly more often in children with inflicted TBI. Intraparenchymal hemorrhage, edema, skull fractures, and cephalohematomas were similar in both groups. Retinal hemorrhage was only identified in the inflicted TBI group. Glasgow Outcome Scale scores indicated a significantly less favorable outcome after inflicted than noninflicted TBI. Mental deficiency was present in 45% of the inflicted and 5% of the noninflicted TBI groups.

CONCLUSIONS

Characteristic features of inflicted TBI included acute computed tomography/magnetic resonance imaging findings of preexisting brain injury, extraaxial hemorrhages, seizures, retinal hemorrhages, and significantly impaired cognitive function without prolonged impairment of consciousness.

Children falling from a height in London

OBJECTIVES

To determine the frequency and geographical distribution of children falling from a height in London and to suggest possible causes and preventative measures.

METHODS

All relevant cases attended by the Helicopter Emergency Medical Service (HEMS) in a three and a half year period were reviewed and the locations related to the boroughs. The rates, per 1,000 resident children, were compared with socioeconomic indices for the boroughs concerned. In addition, a survey was undertaken of window fittings and maintenance in high rise flats close to one particular incident.

RESULTS

A total of 90 incidents were attended involving 91 patients (64 male, 27 female) of whom five died. HEMS attends approximately one third of incidents involving serious trauma. In the study period the maximum frequency was 0.2 fallers per 1,000 resident children, occurring in three boroughs. In three boroughs there were no fallers. There was no overlap in socioeconomic indices between the five boroughs with the highest fall rates and the five with the lowest. The building survey found a high incidence of faulty window catches, a slow response rate for repair, and a lack of safety advice for residents.

CONCLUSIONS

The frequency of falling is related to urban deprivation, poor maintenance, and lack of safety information. A combination of regulation and targeted education could substantially decrease deaths and injuries in children from this cause.

Falls: epidemiology and strategies for prevention

Injury secondary to falls is a largely preventable public health problem. The records of 356 patients admitted following a fall to a level I trauma center over a 32-month period were reviewed to determine the epidemiology and to define possible prevention strategies. Falls constituted 9% of total trauma admissions during this time period and had a mortality of 11% (38 of 356). Two hundred ninety-seven falls were accidental, 36 were due to violent criminal behavior, 16 were from suicide attempts, and 7 were from house fires. Sixty-one children under the age of 13 fell; only one died. Falls out of windows accounted for 36% of these falls with over three-quarters of children falling from three stories or less. Elderly patients (age more than 64 years) accounted for only 44 (14%) of falls but over 50% of the deaths. This mortality rate occurred despite the fact that the majority of these falls were from relatively low heights. There were 224 adult falls (ages 18 to 64 years); 36% were occupation-related, and most were by construction workers, roofers, or painters. The remaining adult fall victims had a high rate of unemployment and alcohol and drug use. This study identified several groups where risk factors for falling permit targeted prevention strategies. A large percentage of children who fell were preschool males who fell from windows and this may be related to the lack of window guard legislation in our area.(ABSTRACT TRUNCATED AT 250 WORDS)

Mandibular fractures in infants: review of the literature and report of seven cases

Mandibular fractures in infants are rare. During the last 50 years, only 13 cases have been recorded in the literature. In this study seven cases of mandibular fractures in infants treated within a period of 3 years are reported. The male-to-female ratio was 6:1. All fractures were caused by short falls, and in all cases the symphysis region was the injured site. The treatment approach was conservative, without any active intervention. The results were satisfactory; perfect alignment of the fractured bone segments was achieved in all cases.

Transport and stabilization of the pediatric trauma patient

The incidence of pediatric trauma continues to increase, presenting at almost every emergency department. Life-threatening injuries need to be cared for immediately, in whatever institution the patient presents. For severely injured children, optimal care is ultimately provided at specialized trauma centers. Physicians caring for trauma patients in less specialized institutions must be aware of who to transfer to a trauma center. Effective stabilization and timely, safe transport are vital to reduce further injury.
