Prehospital predictors of risk for pelvic fractures in pediatric trauma patients

Pelvic fractures are uncommon in children, but can occur as a result of high-energy impact injuries to the lower torso in association with blunt trauma. Pelvic fractures can be associated with significant morbidity while the work-up and treatment for these injuries is costly. The aim was to identify risk factors that help determine which pediatric trauma patients are at highest risk of sustaining a pelvic fracture to aid in the development of criteria for the targeted use of pelvic radiographic imaging. A retrospective analysis was conducted using the only pediatric trauma registry in the state of Maryland, located at The Johns Hopkins Children's Center. All blunt trauma patients who were younger than 15 years of age from 1990 to 2005 were included in the analysis (n = 13,360) with a final diagnosis of pelvic fracture as the primary outcome of interest. Comparisons were made using Pearson's chi-square for categorical and the Mann-Whitney rank sum test for non-normally distributed variables. Pelvic fractures following blunt trauma in children are associated with age, race, place and mechanism of injury. Compared to children 4 years and younger, pelvic fractures were more likely to occur in children aged 5-9 years (OR = 3; P = 0.000), as well as 10-14 years (OR = 5; P = 0.000). Compared to blunt trauma injuries from falls, children who were struck by vehicles or who were occupants in motor vehicle crashes (MVC) were six times (P = 0.000) and twice (P = 0.02) as likely to sustain a pelvic fracture, respectively. Four factors were demonstrated by this study to be significantly associated with pediatric pelvic fractures: being Caucasian, age between 5 and 14 years, being struck as a pedestrian or a motor vehicle crash occupant. Identification of these factors may aid clinicians in selecting patients who are at highest risk for pelvic fracture and may benefit most from pelvic radiography.

Pediatric peripheral vascular injuries and associated orthopedic considerations

Pediatric peripheral vascular trauma is a rare but highly morbid injury in children and is frequently associated with concomitant orthopedic injuries. These children require multidisciplinary care by pediatric, vascular, and orthopedic surgery. In this review, we describe elements of the complex care required for children with peripheral vascular trauma.     

Closed reduction with CT-guided screw fixation for unstable sacroiliac joint fracture-dislocation

Background Unstable posterior pelvic ring fractures and dislocations are uncommon but potentially life-threatening injuries in children. Early definitive management reduces risk of immediate complications as well as chronic pain and gait dysfunction. Conventional operative therapy carries substantial risk of extensive blood loss and iatrogenic neurological and vascular injury. Minimally invasive image-guided intervention may further reduce immediate risk and improve long-term outcome.Objective To describe CT-guided closed reduction and internal fixation (CRIF) and review outcomes of unstable fracture-dislocation of the sacroiliac (SI) joint in children.Materials and methods Between 2000 and 2003, three children (two girls, one boy) age 8–14 years were referred to interventional radiology for treatment of unstable SI joint fracture-dislocation not adequately treated with anterior external fixation alone.Results The three affected SI joints (two left, one right) were treated in a combined approach by pediatric interventional radiologists and orthopedic surgeons, using a percutaneous approach under CT guidance. Over a threaded guiding pin, 7.3 mm cannulated screws were used to achieve stable reduction of the affected SI joints. One screw was removed after slight (2 mm) migration. No neurovascular or other complications occurred. All patients had satisfactory healing with near-anatomic reduction, although recovery of the youngest was delayed by associated spinal injury.Conclusions Compared to open surgical alternatives, CRIF under CT guidance reduces operating time, decreases blood loss, and allows early definitive fixation and immediate non-weight-bearing mobilization with a low rate of complication for unstable posterior pelvic ring fractures. In addition, CT-guided placement of the guide pin may allow safer screw positioning and may minimize the total number of screws needed to achieve pelvic stability.     

Urethral trauma in children

We report our 12-year experience in the management of urethral injuries in nine children, six boys and three girls. The most common mechanisms of injury were motor vehicle accidents, followed by straddle injuries. All the injuries in boys involved the anterior urethra, and in girls the proximal or mid-urethra. There were associated injuries in five, including three pelvic fractures. All children were investigated with a retrograde urethrogram. Four were treated non-operatively with insertion of a urethral catheter. Of the remaining five, one had drainage of a penile haematoma, one cystourethroscopy, two insertion of urinary and suprapubic catheters, and one open cystotomy and passage of a guide wire with antegrade passage of a urethral catheter. Complications included one urinary tract infection, one urethral fistula, one urethrovaginal fistula, and two urethral strictures. Final outcome was satisfactory in all nine children.

The screening pelvic radiograph in pediatric trauma

Background. Pelvic radiographs are routinely obtained in adult trauma to optimise early management. In adults, pelvic fractures are associated with high early transfusion requirement, high injury severity scores and an increased incidence of other abdominal and thoracic injuries. It is unclear whether this holds true in children. Objective. To determine whether the screening pelvic radiograph is necessary in paediatric trauma. Materials and methods. The notes of all patients who presented after trauma to the Starship Children's Hospital and were triaged to the resuscitation room during 1997 were reviewed. Results of initial radiography were obtained and correlated with later imaging. Results. Our review of 444 injured children seen over a period of 1 year revealed that of 347 children who had screening pelvic radiographs, only 1 had a pelvic fracture. The fracture in this child was clinically apparent and required no specific treatment. Conclusions. The presence of a pelvic fracture is rare in injured children. By omitting screening pelvic radiographs there are potential benefits, including reduced radiation exposure to children and cost savings. Uninterpretable or abnormal clinical examination or haematuria requires further investigation, but routine screening for pelvic fracture is unnecessary.

Pediatric Craniomaxillofacial Trauma

The management of fractures in the pediatric patient requires an understanding of craniofacial growth, anatomical differences of the pediatric craniofacial skeleton, and the special needs of the child and family. When possible, specialists trained in pediatric craniomaxillofacial trauma management should be consulted to help manage these complex injuries. For the emergency department physician, a familiarity with these injuries will allow for rapid triage, timely treatment, and favorable results.     

Polytrauma in children

Polytrauma in children is rare, yet trauma is a leading cause of death in children. Clinicians with responsibility for the management of children suffering major trauma must recognise the conflict between these facts. Simulation and preparation can help to improve the quality of care at both individual and institutional levels. Children are not small adults, and their anatomic and physiological differences manifest themselves in different responses to major trauma than those seen in adults. This reality should be met with a tailored approach to assessment, investigation and management that accommodates the changes occurring from infancy, through childhood and adolescence to adulthood. This approach minimizes the risk of harm from inappropriate irradiation or intervention. Children have remarkable resilience and can make dramatic recoveries from seemingly irrecoverable situations. The appropriate treatment of musculoskeletal injuries should therefore not be compromised in the setting of polytrauma, and attention must be given to the optimal time for treatment. Damage control resuscitation and early appropriate care facilitate an individualised response. Outcomes for paediatric polytrauma are improved by management in a specialist centre, with early aggressive management of injuries that require surgical treatment by an experienced multidisciplinary team.     

Blunt Abdominal Trauma in the Pediatric Patient

Timely diagnosis and a rational approach to operative versus nonoperative management of intra-abdominal injuries in children are critical to providing optimal pediatric trauma care. Suspicion of IAI is based on the mechanism of injury and findings on examination. Subsequent evaluation and management of IAI is influenced by the patient's hemodynamic status and the presence of extra-abdominal injuries. The hemodynamically unstable patient with suspected IAI requires emergent laparotomy. The hemodynamically stable patient is evaluated using laboratory and imaging studies, most importantly, CT of the abdomen. Stable patients with hepatic or splenic injuries are almost always managed nonoperatively, whereas small bowel, colon, and pancreatic injuries with main duct disruption require laparotomy.     

Are routine pelvic radiographs in major pediatric blunt trauma necessary?

Background

Screening pelvic radiographs to rule out pelvic fractures are routinely used for the initial evaluation of pediatric blunt trauma. Recently, the utility of routine pelvic radiographs in certain subsets of patients with blunt trauma has been questioned. There is a growing amount of evidence that shows the clinical exam is reliable enough to obviate the need for routine screening pelvic radiographs in children.

Objective

To identify variables that help predict the presence or absence of pelvic fractures in pediatric blunt trauma.

Materials and methods

We conducted a retrospective study from January 2005 to January 2010 using the trauma registry at a level 1 pediatric trauma center. We analyzed all level 1 and level 2 trauma victims, evaluating history, exam and mechanism of injury for association with the presence or absence of a pelvic fracture.

Results

Of 553 level 1 and 2 trauma patients who presented during the study period, 504 were included in the study. Most of these children, 486/504 (96.4%), showed no evidence of a pelvic fracture while 18/504 (3.6%) had a pelvic fracture. No factors were found to be predictive of a pelvic fracture. However, we developed a pelvic fracture screening tool that accurately rules out the presence of a pelvic fracture P?=?0.008, NPV 99, sensitivity 96, 8.98 (1.52–52.8). This screening tool combines eight high-risk clinical findings (pelvic tenderness, laceration, ecchymosis, abrasion, GCS <14, positive urinalysis, abdominal pain/tenderness, femur fracture) and five high-risk mechanisms of injury (unrestrained motor vehicle collision [MVC], MVC with ejection, MVC rollover, auto vs. pedestrian, auto vs. bicycle).

Conclusion

Pelvic fractures in pediatric major blunt trauma can reliably be ruled out by using our pelvic trauma screening tool. Although no findings accurately identified the presence of a pelvic fracture, the screening tool accurately identified the absence of a fracture, suggesting that pelvic radiographs are not warranted in this subset of patients.

Pediatric Trauma Care: An Ongoing Evolution

Trauma remains the leading cause of death and disability in children despite considerable advances in the treatment of injury in the pediatric population. As we move forward into the 21st century, the challenge will be to develop and implement appropriate triage systems to ensure that severely injured children will be treated at centers with a commitment to their care. Issues of overtriage and undertriage need to be addressed, so that the limited resource of PTCs is not overwhelmed by less severely injured patients or conversely, that the definitive management of severe injuries is not delayed by lengthy periods of evaluation at centers ill equipped to care for injured children. PTCs need to take the lead in the development of such integrated pediatric trauma systems. Finally, the importance of injury prevention strategies needs to be emphasized. The vast majority of injuries in children are potentially preventable. Institutions and individuals with a commitment to the care of those injured must also work toward the prevention of the problem in the first place through a combination of research, education, and advocacy. As those who work in the trauma field know, injury is no accident.     

Pediatric thoracic trauma: Current trends

Pediatric thoracic trauma is relatively uncommon but results in disproportionately high levels of morbidity and mortality when compared with other traumatic injuries. These injuries are often more devastating due to differences in children׳s anatomy and physiology relative to adult patients. A high index of suspicion is of utmost importance at the time of presentation because many significant thoracic injuries will have no external signs of injury. With proper recognition and management of these injuries, there is an associated improved long-term outcome. This article reviews the current literature and discusses the initial evaluation, current management practices, and future directions in pediatric thoracic trauma.

Torso vascular trauma

Vascular injury within the chest or abdomen represents a unique challenge to the pediatric general surgeon, as these life- or limb-threatening injuries are rare and may require emergent treatment. Vascular injury may present as life-threatening hemorrhage, or with critical ischemia from intimal injury, dissection, or thrombosis. Maintaining the skillset and requisite knowledge to address these injuries is of utmost importance for pediatric surgeons that care for injured children, particularly for surgeons practicing in freestanding children's hospitals that frequently do not have adult vascular surgery coverage. The purpose of this review is to provide an overview of torso vascular trauma, with a specific emphasis in rapid recognition of torso vascular injury as well as both open and endovascular management options. Specific injuries addressed include blunt and penetrating mediastinal vascular injury, subclavian injury, abdominal aortic and visceral segment injury, inferior vena cava injury, and pelvic vascular injury. Operative exposure, vascular repair techniques, and damage control options including preperitoneal packing for pelvic hemorrhage are discussed. The role and limitations of endovascular treatment of each of these injuries is discussed, including endovascular stent graft placement, angioembolization for pelvic hemorrhage, and resuscitative endovascular balloon occlusion of the aorta (REBOA) in children.     

The clinical presentation of pediatric pelvic fractures

BACKGROUND: Few studies have addressed the presentation and clinical impact of pediatric pelvic fractures. We sought to describe pediatric blunt trauma patients with pelvic fracture (PF) and to evaluate the sensitivity and specificity of physical examination at presentation for diagnosis. METHODS: Retrospective analysis of all PF and control (NPF) patients from our pediatric institution over an 8-year period. RESULTS: A total of 174 patients (88 PF, 86 NPF) were included. Median patient age was 8 years (range, 3 months to 18 years), with 54% males. The most common mechanisms of injury for PF patients were automobile-related accidents (75%). There were 140 patients (87%) who were transported by air or ground medical services. At presentation, approximately 16% of PF patients had a Glasgow Coma score of <15, a mean Revised Trauma Score of 7.49, and a median Injury Severity Score (ISS) of 9. Thirty-one PF patients (35%) had an ISS of >15 indicating severe, multiple injuries. Sixty-eight PF patients (77%) had severe isolated injuries (Abbreviated Injury Scale 1990 value of >3); 11% of PF patients required transfusions, and 2% died. Fifteen PF patients (17% ) had no pelvic ring disruption; 39 (43%) had a single pelvic ring fracture, 22 (2%) had two pelvic ring fractures, 2 (2%) had acetabular fractures, and 10 (11%) had a combination of pelvic fractures. An abnormal physical examination of the pelvis was noted in 81 patients with PF (92% sensitivity, 95% confidence interval [CI] = 0.89-0.95), 15 NPF patients had an abnormal examination (79% specificity, 95% CI = 0.74-0.84). The positive predictive value of the pelvis examination was 0.84, and the negative predictive value was 0.89. The most common abnormal pelvis examination finding was pelvic tenderness in 65 PF patients (73%). A total of seven PF patients had a normal examination of the pelvis; four had a depressed level of consciousness (defined as GCS <15), and six patients had a distracting injury. CONCLUSIONS: Pediatric blunt trauma patients with pelvic fracture represent a severely injured population but generally have lower transfusion rates and mortality than noted in adult studies. The pelvis examination appears to be sensitive and specific in this retrospective study. However, an altered level of consciousness and/or distracting injuries may affect examination sensitivity and specificity. Based on this retrospective study, we cannot advocate eliminating pelvic radiographs in the severely injured, blunt trauma patient. Prospective studies are recommended.     

Multiple trauma in pediatric patients

We analyzed the causes and diagnoses, the treatment, short and long-term outcome of a consecutive series of 70 pediatric polytrauma patients. From 1989 to 1996, 70 children (aged 10 months to 16 years, mean 7.4 years) presented with multiple trauma. A follow-up investigation was performed 4.2 years (mean) after the accident. Traffic accidents (68%) were the leading cause of injuries. Among all injuries (mean ISS 24.6 range 17–57), injuries of the head/neck area were most frequent (87%) followed by extremity fractures (76%) and 135 operations were performed on 55 children, mostly for fracture stabilisation. All multiple injured children survived. At discharge 25 children were still impaired (36% of 70). At follow-up 58 patients were revisited, 11 (19% of 58) presented with impairments, 8 of those (73% of 11) following severe head trauma. This study showed a 10% rate of late impairment due to the severity of the primary head trauma.     

Pediatric orthopedic trauma: principles of management

Musculoskeletal injuries in the pediatric population are unique and require a thorough evaluation by a trained specialist. Unlike adults, many of the injuries may be treated closed due to the amazing growth and remodeling potential of children. Special consideration should be taken in treating certain fracture patterns to prevent the long-term consequences of growth deformities and protect children from child abuse. It is the goal of this article to outline common orthopedic injuries in the pediatric population to facilitate proper care in the multidisciplinary evaluation and treatment of children.     

Abdominal trauma in infants and children: prompt identification and early management of serious and life-threatening injuries. Part II: Specific injuries and ED management

Evaluation of children with suspected abdominal trauma could be a difficult task. Unique anatomic and physiologic features render vital sign assessment and the physical examination less useful than in the adult population. Awareness of injury patterns and associations will improve the early diagnosis of abdominal trauma. Clinicians must have a complete understanding of common and atypical presentations of children with significant abdominal injuries. Knowledge of the utility and limitations of available laboratory and radiologic adjuncts will assist in accurately identifying abdominal injury. While other obvious injuries (eg, facial, cranial, and extremity trauma) can distract physicians from less obvious abdominal trauma, an algorithmic approach to evaluating and managing children with multisystem trauma will improve overall care and help to identify and treat abdominal injuries in a timely fashion. Finally, physicians must be aware of the capabilities of their own facility to handle pediatric trauma. Protocols must be in place for expediting the transfer of children who require a higher level of care. Knowledge of each of these areas will help to improve the overall care and outcome of children with abdominal trauma.
