ABSTRACT
BACKGROUND: Deficits in cognition like working memory (WM) are highly prevalent symptoms related to major depressive disorder (MDD). Neuroimaging studies have described frontoparietal abnormalities in patients with MDD as a basis for these deficits. Based on research in healthy adults, it is hypothesized that increased physical fitness might be a protective factor for these deficits in MDD. However, the relationship between physical fitness and WM-related neural activity and performance has not been tested in MDD, to date. Understanding these associations could inform the development of physical exercise interventions in MDD. METHODS: Within a larger project, 111 (53female) MDD outpatients and 56 (34female) healthy controls performed an n-back task (0-, 1-, 2-, 3-back) during functional Magnetic Resonance Imaging. Physical fitness from a graded exercise test on a cycle ergometer was performed by 106 MDD patients. RESULTS: Patients showed reduced performance particularly at high loads of the n-back WM task and prolonged reaction times at all n-back loads. A whole-brain interaction analysis of group by WM load revealed reduced neural activity in six frontoparietal clusters at medium and high WM loads in MDD patients compared to healthy controls. Analysis of covariance within the MDD sample showed that physical fitness was associated with neural activity in right and left superior parietal lobules. Externally defined Regions of Interest confirmed this analysis. CONCLUSIONS: Results indicate frontoparietal hypoactivity in MDD at high demands, arguing for decreased WM capacity. We demonstrate a parietal fitness correlate which could be used to guide future research on effects of exercise on cognitive functioning in MDD.

BACKGROUND: Cerebrospinal fluid (CSF) leakage is a frequent and challenging complication in neurosurgery, especially in the posterior fossa, with a prevalence of 8%. It is associated with substantial morbidity and increased healthcare costs. A novel dural sealant patch (LIQOSEAL) was developed for watertight dural closure. The objective of this study is to clinically assess the safety and effectiveness of LIQOSEAL as a means of reducing intra- as well as postoperative CSF leakage in patients undergoing elective posterior fossa intradural surgery with a dural closure procedure compared to the best currently available dural sealants. METHODS: We will conduct a two-arm, randomized controlled, multicenter study with a 90-day follow-up. A total of 228 patients will be enrolled in 19 sites, of which 114 will receive LIQOSEAL and 114 an FDA-approved PEG sealant. The composite primary endpoint is defined as intraoperative CSF leakage at PEEP 20 cm H2O, percutaneous CSF leakage within 90 days of, wound infection within 90 days of or pseudomeningocele of more than 20cc on MRI or requiring intervention. We hypothesize that the primary endpoint will not be reached by more than 10 patients (9%) in the investigational arm, which will demonstrate non-inferiority of LIQOSEAL compared to control. DISCUSSION: This trial will evaluate whether LIQOSEAL is non-inferior to control as a means of reducing CSF leakage and safety TRIAL REGISTRATION: ClinicalTrials.gov NCT04086550 .

BACKGROUND: Depression is one of the key factors contributing to difficulties in one's ability to work, and serves as one of the major reasons why employees apply for psychotherapy and receive insurance subsidization of treatments. Hence, an increasing and growing number of studies rely on workability assessment scales as their primary outcome measure. The Work and Social Assessment Scale (WSAS) has been documented as one of the most psychometrically reliable and valid tools especially developed to assess workability and social functioning in patients with mental health problems. Yet, the application of the WSAS in Germany has been limited due to the paucity of a valid questionnaire in the German language. The objective of the present study was to translate the WSAS, as a brief and easy administrable tool into German and test its psychometric properties in a sample of adults with depression. METHODS: Two hundred seventy-seven patients (M = 48.3 years, SD = 11.1) with mild to moderately severe depression were recruited. A multistep translation from English into the German language was performed and the factorial validity, criterion validity, convergent validity, discriminant validity, internal consistency, and floor and ceiling effects were examined. RESULTS: The confirmatory factor analysis results confirmed the one-factor structure of the WSAS. Significant correlations with the WHODAS 2-0 questionnaire, a measure of functionality, demonstrated good convergent validity. Significant correlations with depression and quality of life demonstrated good criterion validity. The WSAS also demonstrated strong internal consistency (α = .89), and the absence of floor and ceiling effects indicated good sensitivity of the instrument. CONCLUSIONS: The results of the present study demonstrated that the German version of the WSAS has good psychometric properties comparable to other international versions of this scale. The findings recommend a global assessment of psychosocial functioning with the sum score of the WSAS. TRIAL REGISTRATION: ISRCTN identifier: ISRCTN28972230 . Date of registration June 26th 2018.

Prejudices can lead to discrimination, social exclusion, and violence particularly among young male adults. Previous findings suggest that the degree of holding prejudices is linked to low levels of empathy, while low levels of empathy have been associated with alexithymia, the inability to experience one's own feelings. We tested the hypothesis that the impact of a lack of empathy on reporting blatant and subtle prejudices is moderated by the inability to identify one's own feelings. In a sample of n = 136 young male adults aged 21 years (mean = 21.5 years; sd = 0.3), we conducted correlation and moderator analyses to determine possible relationships between prejudices, empathy, and alexithymia as assessed by self-report questionnaires. Prejudices were assessed by the Blatant and Subtle Prejudice Scale (BSPS), empathy was assessed by the German modified version of the Interpersonal Reactivity Index (IRI), and alexithymia by the 20-item Toronto Alexithymia Scale (TAS-20). Self-reported empathy levels were correlated with the strength of subtle and blatant prejudices. The moderation analyses revealed that the negative association between empathy and subtle prejudice increased with decreasing alexithymia. The negative association between empathy and blatant prejudice, on the other hand, was significant only for participants with low levels of alexithymia. These results suggest that empathy can limit the expression of blatant and to some degree also subtle prejudice when subjects are capable to identify their own feelings in a group of young males.

The sizeable number of population-based cohort studies of aging in Germany have provided highly valuable contributions for the specification of risk factors and predictors for frequent mental disorders in old age, especially dementia and depression. The results from these cohort studies enable the specification of mechanisms for the development of and preventative interventions for common mental disorders in old age. On the other hand, there is a significant paucity of clinical cohort studies investigating disease trajectories and possible markers for specific individualized interventions of frequent mental disorders in old age. In this article, we report selected key findings from cohort studies of aging and discuss novel approaches for the integration and harmonization of population-based and clinical cohort studies.

Large-amplitude internal gravity waves were observed using Rayleigh lidar temperature soundings above Rio Grande, Argentina ([Formula: see text], [Formula: see text]), in the period 16-23 June 2018. Temperature perturbations in the upper stratosphere amounted to 80 K peak-to-peak and potential energy densities exceeded 400 J/kg. The measured amplitudes and phase alignments agree well with operational analyses and short-term forecasts of the Integrated Forecasting System (IFS) of the European Centre for Medium-Range Weather Forecasts (ECMWF), implying that these quasi-steady gravity waves resulted from the airflow across the Andes. We estimate gravity wave momentum fluxes larger than 100 mPa applying independent methods to both lidar data and IFS model data. These mountain waves deposited momentum at the inner edge of the polar night jet and led to a long-lasting deceleration of the stratospheric flow. The accumulated mountain wave drag affected the stratospheric circulation several thousand kilometers downstream. In the 2018 austral winter, mountain wave events of this magnitude contributed more than 30% of the total potential energy density, signifying their importance by perturbing the stratospheric polar vortex.
ABSTRACT
PURPOSE: Postoperative cognitive dysfunction (POCD) appears in up to 30% of patients suffering from postoperative delirium (POD). Both are associated with higher mortality and postoperative complications, prolonged hospital stays, and increased costs. Multi-modal models with pre-admission risk reduction counselling, perioperative monitoring, and training of multidisciplinary patient care providers have been shown to decrease the prevalence of both. The aim of our study is to understand how far those measures are known and implemented in routine care and to detect potential gaps in the current practice regarding risk communication and information flow between involved caregivers for patients at risk for POD/POCD. PATIENTS AND METHODS: As part of a multicenter study, seven semi-structured focus group (FG) discussions with nurses and physicians from tertiary care hospitals (surgery, anesthesiology, and orthopedics, n=31) and general practitioners (GPs) in private practice (n=7) were performed. Transcribed discussions were analyzed using qualitative content analysis. RESULTS: POD is present above all in the daily work of nurses, whereas physicians do not perceive it as a relevant problem. Physicians report that no regular risk assessment or risk communication was performed prior to elective surgery. Information about POD often gets lost during hand-offs and is not regularly reported in discharge letters. Thus, persisting cognitive dysfunction is often missed. The importance of standardized documentation and continuous education concerning risks, screening, and treatment was emphasized. The often-suggested pre-OP medication adjustment was seen as less important; in contrast, avoiding withdrawal was regarded as far more important. CONCLUSION: Altogether, it seems that standards and available best practice concepts are rarely implemented. In contrast to physicians, nurses are highly aware of delirium and ask for standardized procedures and more responsibility. Therefore, raising awareness regarding risks, screening tools, and effective preventive measures for POD/POCD seems an urgent goal. Nurses should have a central role in coordination and care of POD to prevent the risk for POCD.

BACKGROUND: Aversive stimuli in the environment influence human actions. This includes valence-dependent influences on action selection, e.g., increased avoidance but decreased approach behavior. However, it is yet unclear how aversive stimuli interact with complex learning and decision-making in the reward and avoidance domain. Moreover, the underlying computational mechanisms of these decision-making biases are unknown. METHODS: To elucidate these mechanisms, 54 healthy young male subjects performed a two-step sequential decision-making task, which allows to computationally model different aspects of learning, e.g., model-free, habitual, and model-based, goal-directed learning. We used a within-subject design, crossing task valence (reward vs. punishment learning) with emotional context (aversive vs. neutral background stimuli). We analyzed choice data, applied a computational model, and performed simulations. RESULTS: Whereas model-based learning was not affected, aversive stimuli interacted with model-free learning in a way that depended on task valence. Thus, aversive stimuli increased model-free avoidance learning but decreased model-free reward learning. The computational model confirmed this effect: the parameter lambda that indicates the influence of reward prediction errors on decision values was increased in the punishment condition but decreased in the reward condition when aversive stimuli were present. Further, by using the inferred computational parameters to simulate choice data, our effects were captured. Exploratory analyses revealed that the observed biases were associated with subclinical depressive symptoms. CONCLUSION: Our data show that aversive environmental stimuli affect complex learning and decision-making, which depends on task valence. Further, we provide a model of the underlying computations of this affective modulation. Finally, our finding of increased decision-making biases in subjects reporting subclinical depressive symptoms matches recent reports of amplified Pavlovian influences on action selection in depression and suggests a potential vulnerability factor for mood disorders. We discuss our findings in the light of the involvement of the neuromodulators serotonin and dopamine.

KEY MESSAGE: New QTL for important quality traits in durum were identified, but for most QTL their effect varies depending on the investigated germplasm. Most of the global durum wheat (Triticum turgidum ssp. durum) production is used for human consumption via pasta and to a lower extent couscous and bulgur. Therefore, durum wheat varieties have to fulfill high demands regarding quality traits. In this study, we evaluated the quality traits protein content, sedimentation volume, falling number, vitreousity and thousand kernel weight in a Central European (CP) and a Southern and Western European panel (SP) with 183 and 159 durum lines, respectively, and investigated their genetic architecture by genome-wide association mapping. Except for protein content, we identified QTL explaining a large proportion of the genotypic variance for different traits. However, most of them were identified only in one panel. Nevertheless, for sedimentation volume a genomic region on chromosome 1B appeared important in both durum panels and a BLAST search against the emmer and bread wheat reference genomes points toward the candidate gene Glu-B3. This was further supported by the protein subunit banding pattern via SDS-PAGE gel electrophoresis. For vitreousity, genomic regions on chromosome 7A explained a larger proportion of the genotypic variance in both panels, whereas one QTL, possibly related to the Pinb-2 locus, also slightly influenced the protein content. Within each panel, high prediction abilities for genomic selection were obtained, which, however, dropped considerably when predicting across both panels. Nevertheless, the across-panel prediction ability was still larger than 0.4 for protein content and sedimentation volume, underlining the potential for genomics-aided durum breeding, if laboratory and logistical facilities are available.

Stress plays a key role in modulating addictive behavior and can cause relapse following periods of abstinence. Common effects of stress and alcohol on the dopaminergic system have been suggested, although the precise mechanisms are unclear. Here, we investigated 20 detoxified alcohol-dependent patients and 19 matched healthy controls and assessed striatal D2/D3 availability using [18F]-fallypride positron emission tomography and stressful life events. We found a strong association between striatal D2/D3 availability and stress in patients, but not in healthy controls. Interestingly, we found increased D2/D3 receptor availability in patients with higher stress levels. This mirrors complex interactions between stress and alcohol intake in animal studies and emphasizes the importance to investigate stress exposure in neurobiological studies of addiction.

Acute psychiatric wards are an important element in the mental healthcare of people at risk for acute harm to others or self-harm. Unfortunately, aggression, violence (conflict) and the use of coercion (containment) are still part of psychiatric care. The decisive factor for the correct handling of these situations is the quantity as well as the quality of the employees. Therefore, the present study dealt with the care situation on acute psychiatric wards. The hypothesis is that both the number of beds on the acute psychiatric ward and the number of caregivers have an impact on the occurrence of conflict and containment. For this purpose, data were collected in 6 clinics on a total of 12 acute psychiatric wards. The Patient Staff Conflict Checklist - Shift Report (PCC-SR) was used as the data entry tool. A total of 2026 shifts (early, late and night shifts) were recorded and evaluated. The staffing of the wards with nursing personnel varied considerably. The results show that both the size of the ward and also the number of caregivers on acute psychiatric wards have a significant impact on the occurrence of conflicts. The results also show that the incidence of conflicting behavior of patients differs both in terms of the wards of the hospitals involved and in the type of service considered. In addition, it can be seen that the extent of closure of an acute ward (i.â¯e. the closed ward or entrance door) and the size of a ward (i.â¯e. the number of beds) have a negative impact on the incidence of inpatient acute psychiatric contexts. The occurrence of conflict behavior can lead to alien or self-endangerment and to a variety of de-escalating and containment measures. This requires appropriate human resources.

BACKGROUND: Outcomes after extremely preterm birth (<28â¯weeks gestation) have been studied intensely, and follow-up into adulthood is well-established. Following the introduction of the International Classification of Functioning, Disability and Health, participation has been recognized to be a relevant outcome in rehabilitation research. During adolescence, participation is crucial to adapting to new social roles. The aim of our study was to investigate participation in the domains Autonomy, Relationships and Community Recreation. METHODS: Participation was assessed as part of a cross-sectional, population-based study in a German federal state examining all adolescents born between January 1997 and December 1999 at under 27â¯weeks gestation. Of the surviving 90 adolescents, 72 (80%) were followed-up at age 14 to 17. Frequency of participation was assessed using the short form of the Questionnaire of Young People's Participation and compared to matched peers. Associations with physical, cognitive, and psychological functioning and contextual factors were examined using multivariate regression. RESULTS: Frequency of participation in Autonomy, Relationships, and Community Recreation in adolescents born extremely preterm was significantly lower than that of matched peers from the general population (pâ¯<â¯0,001). Lower frequency of participation in Autonomy and Relationships was associated with severe physical and cognitive impairment, and psychological problems. Fifty-seven percent of the adjusted variance in Autonomy and 31% of the adjusted variance in Relationships was explained by our regression models. CONCLUSION: Further research is warranted to investigate additional factors associated with the restricted frequency of participation of adolescents born preterm to design suitable interventions for improving participation.

KEY MESSAGE: Simultaneous improvement of protein content and grain yield by index selection is possible but its efficiency largely depends on the weighting of the single traits. The genetic architecture of these indices is similar to that of the primary traits. Grain yield and protein content are of major importance in durum wheat breeding, but their negative correlation has hampered their simultaneous improvement. To account for this in wheat breeding, the grain protein deviation (GPD) and the protein yield were proposed as targets for selection. The aim of this work was to investigate the potential of different indices to simultaneously improve grain yield and protein content in durum wheat and to evaluate their genetic architecture towards genomics-assisted breeding. To this end, we investigated two different durum wheat panels comprising 159 and 189 genotypes, which were tested in multiple field locations across Europe and genotyped by a genotyping-by-sequencing approach. The phenotypic analyses revealed significant genetic variances for all traits and heritabilities of the phenotypic indices that were in a similar range as those of grain yield and protein content. The GPD showed a high and positive correlation with protein content, whereas protein yield was highly and positively correlated with grain yield. Thus, selecting for a high GPD would mainly increase the protein content whereas a selection based on protein yield would mainly improve grain yield, but a combination of both indices allows to balance this selection. The genome-wide association mapping revealed a complex genetic architecture for all traits with most QTL having small effects and being detected only in one germplasm set, thus limiting the potential of marker-assisted selection for trait improvement. By contrast, genome-wide prediction appeared promising but its performance strongly depends on the relatedness between training and prediction sets.

BACKGROUND: Operative treatment of diaphyseal fractures of the femur in older children and adolescents remains controversial due to multiple surgical options and higher complication rates in single-center studies compared to younger children. This retrospective multicenter study aimed to register early and late complications in day-by-day treatment. MATERIAL AND METHODS: Sixteen hospitals with particular expertise in pediatric orthopedic trauma participated in this study. Patients with diaphyseal femur fractures, a body weight ≥50 kg (aged 10-16 years) and treated between 2008 and 2012 were included. Age, weight, fracture type, and choice of operative treatment were correlated to complication rate and type. Patients with pathologic fractures and/or metabolic bone disorders were excluded. RESULTS: Fifty-three children (15 females and 38 males; mean age: 14.2 y [SD 1.4 y]; mean body weight: 60.5 kg [max. 95 kg]) with 54 fractures were included. Elastic stable intramedullary nailing (ESIN) was the treatment of choice in 31 of 42 fractures with open growth plates. In the subgroup with two nails, 7 of 12 patients experienced revision surgery due to instability or shortening. Three patients with ESIN and end caps had no complications. In the subgroup with three inserted nails (11 patients), one patient was converted to external fixation. Nine patients received primary or secondary plate osteosyntheses. Within this group, two patients had deep infections; one implant failure, and one peri-implant fracture were recorded. Adolescent lateral femoral nailing (ALFN), when used as the primary treatment option in two patients, was free of complications. When used as a secondary treatment option in three patients, one patient had a pseudarthrosis and one an infection. Both were treated in further operative procedures. In a group of eight patients with closed physes, regular intramedullary nailing as primary or secondary treatment of choice resulted in one locking screw change. As late complications, leg length discrepancy (LLD) over 15 mm (n = 2) and loss of range of motion (ROM) (n = 4; two knee and three hip) were noted in patients receiving multiple revisions or serious postoperative complication. CONCLUSIONS: Children older than 10 years of age with a body weight ≥50 kg and open physes are prone to complications regardless of treatment choice. A smaller revision rate occurred in patients treated with ESIN and end caps or a third nail compared to the other treatment options. When physes are closed, rigid intramedullary nailing is the treatment of choice.
ABSTRACT
BACKGROUND: First rank symptoms (FRS) of schizophrenia have been used for decades for diagnostic purposes. In the new version of the DSM-5, the American Psychiatric Association (APA) has abolished any further reference to FRS of schizophrenia and treats them like any other "criterion A" symptom (e.g. any kind of hallucination or delusion) with regard to their diagnostic implication. The ICD-10 is currently under revision and may follow suit. In this review, we discuss central points of criticism that are directed against the continuous use of first rank symptoms (FRS) to diagnose schizophrenia. METHODS: We describe the specific circumstances in which Schneider articulated his approach to schizophrenia diagnosis and discuss the relevance of his approach today. Further, we discuss anthropological and phenomenological aspects of FRS and highlight the importance of self-disorder (as part of FRS) for the diagnosis of schizophrenia. Finally, we will conclude by suggesting that the theory and rationale behind the definition of FRS is still important for psychopathological as well as neurobiological approaches today. RESULTS: Results of a pivotal meta-analysis and other studies show relatively poor sensitivity, yet relatively high specificity for FRS as diagnostic marker for schizophrenia. Several methodological issues impede a systematic assessment of the usefulness of FRS in the diagnosis of schizophrenia. However, there is good evidence that FRS may still be useful to differentiate schizophrenia from somatic causes of psychotic states. This may be particularly important in countries or situations with little access to other diagnostic tests. FRS may thus still represent a useful aid for clinicians in the diagnostic process. CONCLUSION: In conclusion, we suggest to continue a tradition of careful clinical observation and fine-grained psychopathological assessment, including a focus on symptoms regarding self-disorders, which reflects a key aspect of psychosis. We suggest that the importance of FRS may indeed be scaled down to a degree that the occurrence of a single FRS alone should not suffice to diagnose schizophrenia, but, on the other hand, absence of FRS should be regarded as a warning sign that the diagnosis of schizophrenia or schizoaffective disorder is not warranted and requires specific care to rule out other causes, particularly neurological and other somatic disorders. With respect to the current stage of the development of ICD-11, we appreciate the fact that self-disorders are explicitly mentioned (and distinguished from delusions) in the list of mandatory symptoms but still feel that delusional perceptions and complex hallucinations as defined by Schneider should be distinguished from delusions or hallucinations of "any kind". Finally, we encourage future research to explore the psychopathological context and the neurobiological correlates of self-disorders as a potential phenotypic trait marker of schizophrenia.

Mental disorders are among the greatest medical and social challenges facing us. They can occur at all stages of life and are among the most important commonly occurring diseases. In Germany 28 % of the population suffer from a mental disorder every year, while the lifetime risk of suffering from a mental disorder is almost 50 %. Mental disorders cause great suffering for those affected and their social network. Quantitatively speaking, they can be considered to be among those diseases creating the greatest burden for society due to reduced productivity, absence from work and premature retirement. The Federal Ministry of Education and Research is funding a new research network from 2015 to 2019 with up to 35 million euros to investigate mental disorders in order to devise and develop better therapeutic measures and strategies for this population by means of basic and translational clinical research. This is the result of a competitive call for research proposals entitled research network for mental diseases. It is a nationwide network of nine consortia with up to ten psychiatric and clinical psychology partner institutions from largely university-based research facilities for adults and/or children and adolescents. Furthermore, three cross-consortia platform projects will seek to identify shared causes of diseases and new diagnostic modalities for anxiety disorders, attention deficit hyperactivity disorders (ADHS), autism, bipolar disorders, depression, schizophrenia and psychotic disorders as well as substance-related and addictive disorders. The spectrum of therapeutic approaches to be examined ranges from innovative pharmacological and psychotherapeutic treatment to novel brain stimulation procedures. In light of the enormous burden such diseases represent for society as a whole, a sustainable improvement in the financial support for those researching mental disorders seems essential. This network aims to become a nucleus for long overdue and sustained support for a German center for mental disorders.

UNLABELLED: Thirty-five thousand four hundred eighty-three female osteoporosis patients were compared with 35,483 patients without osteoporosis regarding the incidence of depression. The risk of depression is significantly increased for patients with osteoporosis compared with patients without osteoporosis in primary care practices within Germany. INTRODUCTION: The objectives of the present study were to analyze the incidence of depression in German female patients with osteoporosis and to evaluate the risk factors for depression diagnosis within this patient population. METHODS: This study was a retrospective database analysis conducted in Germany utilizing the Disease Analyzer® Database (IMS Health, Germany). The study population included 70,966 patients between 40 and 80 years of age from 1072 primary care practices. The observation period was between 2004 and 2013. Follow-up duration was 5 years and was completed in April 2015. A total of 35,483 osteoporosis patients were selected after applying exclusion criteria, and 35,483 controls were chosen and then matched (1:1) to osteoporosis patients based on age, sex, health insurance coverage, depression diagnosis in the past, and follow-up duration after index date. The analyses of depression-free survival were carried out using Kaplan-Meier curves and log-rank tests. Cox proportional hazards models (dependent variable: depression) were used to adjust for confounders. RESULTS: Depression diagnoses were presented in 33.0 % of the osteoporosis group and 22.7 % of the control group after the 5-year follow-up (p < 0.001). Dementia, cancer, heart failure, coronary heart disease, and diabetes were associated with a higher risk of developing depression (p < 0.001). Private health insurance was associated with a lower risk of depression. There was no significant effect of fractures on depression risk. CONCLUSION: The risk of depression is significantly increased for patients with osteoporosis in primary care practices within Germany.

BACKGROUND: Femoral shaft fractures comprise around 4 % of all long-bone fractures in childhood. There is controversy about the treatment of fractures in children below 5 years, between those preferring non-operative methods, such as casting or traction, and those supporting elastic stable intramedullary nailing (ESIN). METHODS: This retrospective study evaluates the day-by-day treatment of femoral shaft fractures in children aged 6-60 months in four major paediatric surgery trauma centres in Germany from 1 January 2004 to 31 December 2011 by chart review. We analysed all patient-related data, causes of fracture, fracture type, treatment method and potential post-treatment complications. RESULTS: We identified 225 patients (male to female 2:1) with femoral shaft fractures. Around 2/3 of these resulted from falls of less than 1 m or 1-3 m, the most frequent result (>40 %) being a long spiral fracture. All 19 children below 1 year of age were treated by casting or traction. Between the ages of 12 and 24 months (n = 56), different treatment concepts were preferred (1/5 ESIN, 2/5 traction and 2/5 spica casting). Between 24 and 36 months, operative and non-operative therapies were equally distributed. In children older than 36 months (n = 64), most fractures were treated by ESIN: six children by external fixation and 14 by other treatments like spica casting, plate osteosynthesis or a combination of methods. 42 changes of treatment were performed: traction to spica casting or secondary operative treatment and 21 complications occurred (nails left in place for too long, skin defects or wound infections). CONCLUSIONS: Spica casting of femoral shaft fractures or, in some cases, traction is still the preferred treatment in the first and second years of life. In the third year, children are treated operatively as well as non-operatively, although now there is no current evidence of better short-term outcomes in operatively treated children. But elastic stable intramedullary nailing is the standard treatment for femoral shaft fractures in children older than 3 years of age.
