Paediatric spine injuries in the thoracic and lumbar spine-results of the German multicentre CHILDSPINE study.

BACKGROUND: Paediatric thoracolumbar spine injuries are rare, and meaningful epidemiological data are lacking. OBJECTIVES: The aim of this study was to provide epidemiological data for paediatric patients with thoracolumbar spinal trauma in Germany with a view to enhancing future decision-making in relation to the diagnostics and treatment of these patients. MATERIALS AND METHODS: A retrospective multicentre study includes patients up to 16 years of age who were suffering from thoracolumbar spine injuries who had been treated in six German spine centres between 01/2010 and 12/2016. The clinical database was analysed for patient-specific data, trauma mechanisms, level of injury, and any accompanying injuries. Diagnostic imaging and subsequent treatment were investigated. Patients were divided into three age groups for further evaluation: age group I (0-6 years), age group II (7-9 years) and age group III (10-16 years). RESULTS: A total of 153 children with 345 thoracolumbar spine injuries met the inclusion criteria. The mean age at the time of hospitalization due to the injury was 12.9 (± 3.1) years. Boys were likelier to be affected (1:1.3). In all age groups, falls and traffic accidents were the most common causes of thoracolumbar spine injuries. A total of 95 patients (62.1%) were treated conservatively, while 58 (37.9%) of the children underwent surgical treatment. Minimally invasive procedures were the most chosen procedures. Older children and adolescents were likelier to suffer from higher-grade injuries according to the AOSpine classification. The thoracolumbar junction (T11 to L2) was the most affected level along the thoracolumbar spine (n = 90). Neurological deficits were rarely seen in all age groups. Besides extremity injuries (n = 52, 30.2%), head injuries represented the most common accompanying injuries (n = 53, 30.8%). Regarding spinal injuries, most of the patients showed no evidence of complications during their hospital stay (96.7%). CONCLUSIONS: The thoracolumbar junction was more frequently affected in older children and adolescents. The majority of thoracolumbar spinal column injuries were treated conservatively. Nevertheless, 37.9% of hospitalized children had to be treated surgically, and there was an acceptable complication rate for the surgeries that were performed.

Pediatric cervical spine injuries-results of the German multicenter CHILDSPINE study.

OBJECTIVES: The aim of this study was to provide epidemiological data of pediatric patients suffering from cervical spinal trauma in Germany, in order to integrate these data in future decision-making processes concerning diagnosis and therapy. MATERIALS AND METHODS: Retrospective multicenter study includes all patients up to 16 years suffering from cervical spine injuries who were treated in six German spine centers between 01/2010 and 12/2016. The clinical databases were screened for specific trauma mechanism, level of injury as well as accompanying injuries. Diagnostic imaging and the chosen therapy were analyzed. Patients were divided into three age groups for further evaluation: age group I (0-6 years), age group II (7-9 years), age group III (10-16 years). RESULTS: A total of 214 children with 265 cervical spine injuries were included during the mentioned period. The mean age at the time of injury was 11.9 (± 3.9) years. In age group I, 24 (11.2%) patients were included, age group II consisted of 22 patients (10.3%), and 168 patients belonged to age group III (78.5%). Girls and boys were equally affected. In all age groups, falls and traffic accidents were the most common causes of cervical spine injuries. A total of 180 patients (84.1%) were treated conservatively, while 34 (15.9%) children underwent surgery. Distorsion/whiplash injury was the most common entity (n = 165; 68.2%). Children aged 0-9 years had significantly (p < 0.001) more frequent injuries of the upper cervical spine (C0-C2) compared to older age groups. Patients of age group III were more likely to suffer from injuries in subaxial localizations. Neurological deficits were rarely seen in all age groups. Head injuries did represent the most common accompanying injuries (39.8%, n = 92). CONCLUSIONS: The upper cervical spine was more frequently affected in young children. Older children more often suffered from subaxial pathologies. The majority of cervical spinal column injuries were treated conservatively. Nevertheless, 15% of the hospitalized children had to be treated surgically.

[Diagnostics and treatment of cervical spine trauma in pediatric patients : Recommendations from the Pediatric Spinal Trauma Group]. / Diagnostik und Therapie von Verletzungen der Halswirbelsäule im Kindesalter : Empfehlungen der AG Wirbelsäulentrauma im Kindesalter.

BACKGROUND: Severe cervical spine injuries in children under the age of 17 years are rare. Recommendations or even guidelines for the diagnostics and treatment of such injuries in children are currently not available. OBJECTIVE: The aim of the study was to formulate recommendations for diagnostics and treatment of injuries of the cervical spine in pediatric patients. MATERIAL AND METHODS: First, a search of primary and secondary literature on the topic complex of diagnostics and treatment of cervical spine injuries in children was carried out. An appropriate internal literature database was defined and maintained. Second, within the framework of 9 meetings from April 2017 to December 2019 the members of the Pediatric Spinal Trauma Group of the Spine Section of the German Society for Orthopaedics and Trauma (DGOU) systematically formulated recommendations for the diagnostics and treatment of injuries of the cervical spine in pediatric patients by a consensus process. RESULTS: Recommendation for the diagnostics and treatment for injuries of the cervical spine could be formulated for three age groups (age group I: 0-6 years; age group II: 7-9 years; age group III: 10-16 years). The diagnostic and therapeutic principles known from adult patients suffering from injuries to the cervical spine cannot be easily transferred to pediatric patients. CONCLUSION: Injuries to the pediatric spine are rare and should be treated in specialized spine centers. Pediatric patients with a stable cardiopulmonary status should undergo magnetic resonance imaging (MRI) if a spinal trauma is suspected. Classification systems and therapeutic recommendations for injuries to the cervical spine known from adult patients could also be used for adolescent patients. This is not possible for children under the age of 10 years. Only few classification systems exist for this age group. Basic principles of the treatment of spinal trauma in children is the restoration of spinal stability and correct anatomical relationships as well as the protection of all neural structures.

[Diagnostics and treatment of thoracic and lumbar spine trauma in pediatric patients : Recommendations from the Pediatric Spinal Trauma Group]. / Diagnostik und Therapie von Verletzungen der Brust- und Lendenwirbelsäule im Kindesalter : Empfehlungen der AG Wirbelsäulentrauma im Kindesalter.

BACKGROUND: Spinal injuries in pediatric patients are overall very rare. Current reference studies including large patient numbers that enable the formulation of evidence-based recommendations on diagnostics and treatment of these injuries do not exist. OBJECTIVE: The aim of the current study was to formulate recommendations on the diagnostics and treatment for injuries of the thoracic and lumbar spine in pediatric patients. MATERIAL AND METHODS: Firstly, a search for primary and secondary literature on the topic of diagnostics and treatment of spinal injuries in children was carried out. From this, a literature database was established and maintained. Secondly, within the framework of 9 meetings in the time period from April 2017 to December 2019 the members of the Pediatric Spinal Trauma Group of the Spine Section of the German Society for Orthopaedics and Trauma (DGOU) documented recommendations on diagnostics and treatment of injuries of the thoracic and lumbar spine in pediatric patients by a consensus process. RESULTS: Recommendations on the diagnostics and treatment of injuries of the thoracic and lumbar spine could be given for 3 age groups (age group I: 0-6 years; age group II: 7-9 years; age group III: 10-16 years). Diagnostic and therapeutic principles known from adult patients suffering from injuries to the thoracic or lumbar spine cannot easily be transferred to pediatric patients. CONCLUSION: Spinal injuries in childhood are rare and should be treated in specialized spine centers. Pediatric patients with a stable cardiopulmonary status should undergo magnetic resonance imaging (MRI) if a spinal trauma is suspected. The basic principles of the treatment of spinal trauma in children is the restoration of spinal stability and correct anatomical parameters as well as the protection of all neural structures. The potential for correction and regeneration of the individual spinal sections depending on the age of the patient must be considered for deciding between operative vs. conservative treatment. Whenever operative treatment is needed, it should be performed by minimally invasive techniques as a sole instrumentation without spondylodesis. An early removal of the screw-rod-system should be performed.

[Pediatric spine trauma-Results of a German national multicenter study including 367 patients]. / Wirbelsäulenverletzungen im Kindesalter ­ Ergebnisse einer nationalen Multizenterstudie mit 367 Patienten.

BACKGROUND: In general, pediatric spinal injuries are rare. No reliable data on the epidemiology of spinal injuries in pediatric patients in Germany are available. Especially in pediatric patients, for whom the medical history, clinical examination and the performance of imaging diagnostics are difficult to obtain, all available information on a spinal injury must be taken into account. OBJECTIVE: The aim of this study was to provide epidemiological data for pediatric patients with spinal trauma in Germany in order to enhance future decision-making for the diagnostics and treatment of these patients. MATERIAL AND METHODS: Within the framework of a national multicenter study, data were retrospectively obtained from 6 German spine centers for 7 years between January 2010 and December 2016. In addition to the demographic data, the clinical databases were screened for specific trauma mechanisms, level of injury as well as accompanying injuries. Furthermore, diagnostic imaging and the treatment selected were also analyzed. RESULTS: A total of 367 children (female: male = 1:1.2) with a total of 610 spinal injuries were included in this study. The mean age was 12 years (±3.5 years). The most frequent trauma mechanisms were falls from <3 m and traffic accidents. The imaging diagnostics were only rarely carried out with the child under anesthesia. Younger children (0-9 years old) suffered more injuries to the cervical spine, whereas injuries to the thoracic and lumbar spine were more frequently found in older children (>10 years old). The children frequently showed accompanying injuries to the head and the extremities. Accompanying spinal injuries mostly occurred in adjacent regions and only rarely in other regions. Around 75% of the children were treated conservatively. CONCLUSION: The results were different from the knowledge obtained from adult patients with spinal trauma and describe the special circumstances for pediatric patients with spinal trauma. Despite certain limitations these facts may help to enhance future decision-making for the diagnostics and treatment of these patients.

[Osteochondral fractures in childhood and adolescence]. / Osteochondrale Frakturen im Kindes- und Jugendalter.

BACKGROUND: Osteochondral fractures (OCF) are traumatic shearing injuries to portions of cartilage and bone. The most common cause is patellar dislocation, with the main localisation being the medial patellar facet and the lateral femoral condyle. They can occur in all age groups. DIAGNOSIS: Clinically, there is a painful knee joint effusion (haemarthrosis) with a "dancing patella". This is usually accompanied by restricted movement and/or a locking phenomenon. In addition to the standard X­ray of the knee in three planes (lateral, anterior-posterior and tangential patella), an MRI should be performed promptly in the case of haemarthrosis and suspicious symptoms, as concomitant injuries are present in up to 70% of cases. TREATMENT: The aim of treatment is to restore joint congruence in order to prevent the risk of secondary osteoarthritis. Small chondral and stable osteochondral fractures can be treated conservatively. Surgery is indicated for all other OCFs. In addition to refixation with various materials (bioresorbable screws, bone plugs, suture material and Kirschner wires), cartilage regeneration procedures (AMIC, MACI, OAT, etc.) are available for late diagnosed or non-refixable fragments. However, the number of cases is small. CONCLUSION: Osteochondral fractures are rare injuries in children and adolescents. Prompt MRI is recommended for diagnosis in cases of suspected OCF. Refixation is the preferred treatment method, with bioresorbable implants showing promising results in reducing the need for additional surgery. The risk of secondary osteoarthritis can be reduced with regular treatment.

[Treatment of proximal humeral fractures in childhood and adolescence : Consensus report of the pediatric traumatology section of the German Society for Trauma Surgery]. / Die Behandlung der proximalen Humerusfraktur im Kindes- und im Jugendalter : Konsensusbericht der Sektion Kindertraumatologie der DGU.

BACKGROUND: Proximal humeral fractures are a relatively common injury in childhood and adolescence, accounting for 0.45-2% of all fractures [2, 18]. Treatment is usually conservative but is still the subject of a scientific debate [9, 12]. In addition to the S1-LL, there are different recommendations for the diagnostics and treatment of these fractures in the literature. METHODOLOGY: As part of the 10th scientific meeting of the SKT of the DGU, the existing recommendations and the relevant or current literature were critically discussed by a panel of experts and a consensus was formulated. An algorithm for the diagnostics, therapy and treatment was integrated into this. RESULTS: The measurement of axial deviation and tilt is not interobserver and intraobserver reliable [3]. The age limit for when complete correction is possible was set at an age of 10 years, as the correction potential changes around this age. For diagnostic purposes, well-centered X­ray images in 2 planes (true AP and Y­images without thoracic parts) is defined as the standard. At the age of less than 10 years, any malposition can be treated conservatively with Gilchrist bandaging for 2-3 weeks. Surgery can only be indicated in individual cases, e.g., in the event of severe pain or the need for rapid weight bearing. An ad latus displacement of more than half the shaft width should not be tolerated over the age of 10 years. Due to the variance in the measurement results, it is not possible to recommend surgical treatment depending on the extent of the ad axim dislocation. As a guideline, the greater the dislocation and the closer the child is to growth joint closure, the more likely surgical treatment is indicated. The development should be taken into account. The gold standard is retrograde, radial and unilateral ESIN osteosynthesis using two intramedullary nails. Osteosynthesis does not require immobilization. A follow-up X­ray is planned for unstable fractures without osteosynthesis after 1 week, otherwise optional for documentation of consolidation after 4-6 weeks, e.g., if sports clearance is to be granted and before metal removal (12 weeks). CONCLUSION: Recommendations for surgical indications based on the extent of tilt are not reproducible and seem difficult in view of the current literature [3, 9, 12]. A pragmatic approach is recommended. The prognosis of the fracture appears to be so good, taking the algorithm into account, that restitutio ad integrum can be expected in most cases.

Incidence, treatment techniques, and results of distal humeral coronal shear fractures in children and adolescents-a multicenter study of the German Section of Pediatric Traumatology (SKT).

PURPOSE: Distal humeral coronal shear fractures (CSF) are uncommon and may be challenging to treat due to their size, location, and intraarticular nature. The purpose of this study was to analyze treatment concepts of this rare entity in the growing age. METHODS: Based on a multi-center data analysis we retrospectively reviewed patients below 16 years of age with CSF treated at 13 high-volume pediatric trauma centers. RESULTS: Data from 51 patients with a CSF treated between 01/2012 and 12/2021 were analyzed. The mean age was 12.9 years (10-15), and there was a trend towards male patients (30: 21). The initial diagnostic approach was conventional X-ray in all cases. In addition, a CT scan (n = 33), MRI scan (n = 9), or both (n = 3) were performed. All fractures except two showed relevant displacement. Consequently, only two cases received conservative treatment consisting of plaster immobilization. Surgical treatment was performed in 49 cases consisting of open or mini-open reduction and metal/resorbable screw osteosynthesis (n = 39), plates (n = 4), K-wire pinning (n = 6), and others (n = 6), as well as combinations. In 1 case open reduction without osteosynthesis was performed. Postoperative additional plaster immobilization was performed in 40 cases (for a mean of 19 days (2-42)), physiotherapy was initiated in 29 cases, and metal removal was performed in 28 cases (after a mean of 18.1 weeks (4-44)). After a mean follow-up of 9.9 months (2-25), elbow axial deviation (5° valgus) was observed in one case and mild loss of elbow ROM in six cases (11.7%). Complications included revision of the osteosynthesis because of insufficient articular reconstruction (n = 4), removal of a free joint body (n = 1), an osteonecrosis (n = 1), and a cartilage defect (n = 1). CONCLUSION: In pediatric patients CSFs start to occur at the age of 10, but are typically observed at the age of 13 and older. Because of their intraarticular nature and predilection toward displacement, these fractures are frequently treated operatively. The surgical strategy requires open reduction and anatomic reconstruction of the articular surface. Stable internal fixation, most often achieved by screws, permits early mobilization and leads to good outcomes in most cases. This is presumably due to the fact that mostly simple fractures occur in children and mostly complex injuries in older adults. LEVEL OF EVIDENCE: III, retrospective analysis.

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.

Prevention of severe injuries of child passengers in motor vehicle accidents: is re-boarding sufficient?

PURPOSE: The purpose of this study was to evaluate whether prolonged re-boarding of restraint children in motor vehicle accidents is sufficient to prevent severe injury. METHODS: Data acquisition was performed using the Trauma Register DGU® (TR-DGU) in the time period from 2010 to 2019 of seriously injured children (AIS 2 +) aged 0-5 years as motor vehicle passengers (MVP). Primarily treated and transferred patients where included. RESULTS: The study group included 727 of 2030 (35.8%) children, who were severely injured (AIS 2 +) in road traffic accidents, among them 268 (13.2%) as MVPs in the age groups: 0-1 years (42.5%), 2-3 years (26.1%) and 4-5 years (31.3%). The pattern of severe injury was head/brain (56.0%), thoracic (42.2%), abdominal (13.1%), fractures (extremities and pelvis, 52.6%) and spine/severe whiplash (19.8%). The 0-1-year-old MVPs showed the significantly highest proportion of brain injuries with Glasgow Coma Score (GCS) < 8 and severe injury to the spine. The 2-3-year-olds showed the significantly highest proportion of fractures especially the lower extremity and highest proportion of cervical spine injuries of all spine injuries, while the 4-5-year-olds, the significantly highest proportion of abdominal injury and second highest proportion of cervical spine injury of all spine injuries. MVPs of the 0-1-year-old and 2-3-year-old groups showed a higher median Injury Severity Score (ISS) of 21.5 and 22.1 points than the older children (17.0 points). They also suffered an AIS-6-injury significantly more often (9 of 21) of spine (p = 0.001). Especially the cervical spine was significantly more often involved. Passengers at the age of 0-1 years were treated with cardiopulmonary resuscitation (CPR) three times as often as older children in the prehospital setting and twice as often at admission in the Trauma Resuscitation Unit (TRU). Their survival rate was 7 out of 8 (0-1 years), 1 out of 6 (2-3 years) and 1 out of 4 (4-5 years). CONCLUSION: Although the younger MVPs are restraint in a re-boarding position, severe injury to the spine and head occurred more often, while older children as front-faced positioned MVPs suffered from significantly higher rates of abdominal and more often severe facial injury. Our data show, that it is more important to properly restrain children in their adequate car seats (i-size-Norm) and additionally consider the age-related physiological and anatomical specific risks of injury as well as co-factors in road traffic accidents, than only prolonging the re-boarding position over the age of 15 months as a single method.
