Abstract
Background Olecranon fractures are common injuries that can occur in patients of any age. To assess the postoperative outcome, multiple scoring systems like the DASH, MEPS und Morrey Score have been described. The goal of this paper is to compare the subjective elbow value (SEV) to these commonly used scoring systems. We hypothesized that the SEV would have a high correlation and practicability for the evaluation of elbow function after isolated olecranon injury.
Patients and Methods Clinical data of 40 patients were collected and retrospectively analysed. All patients suffered an isolated olecranon fracture and were surgically treated by tension band wiring or plate fixation. In the follow-up examinations the Mayo Score, DASH Score, Morrey Score and SEV were measured for correlation purposes.
Results The mean follow-up time was 70.5 ± 45.6 months. The median DASH Score was 9.9 (4.1 – 20.4) and 100 (85 – 100) for the MEPS. The median Morrey Score was 98 (92 – 100). The median SEV was 90% (80 – 95%). The Pearson correlation between the DASH and SEV was −0.85 and 0.80 between the MEPS and the SEV.
Conclusions The SEV shows a high correlation to the most commonly used scoring systems for outcome evaluation after elbow injury. It is easy to use and can be seen as a valuable tool to assess patients after olecranon fractures.

Dysphagie bei tracheotomierten Patienten nach Langzeitbeatmung
Authors: Heidler M.-D. 
Published: September 2019

ZusammenfassungUnabhängig von der Art der kritischen Erkrankung haben tracheotomierte Patienten ein hohes Risiko für die Entwicklung einer Schluckstörung. Diese ist potenziell lebensbedrohlich, da sie zu Aspiration und Pneumonie führen kann. Vor einer oralen Nahrungsgabe sollte daher unbedingt eine Schluckdiagnostik mittels Bolusfärbetest und/oder FEES durchgeführt werden. Da ein physiologischer Luftstrom durch den Larynx und ein adäquater subglottischer Druck Schlüsselkomponenten eines effektiven Schluckaktes sind, sollte eine Oralisierung bei geblockter Trachealkanüle möglichst vermieden werden.

AbstractThe main purpose of this study was to compare the effects on strength and muscle power of a training program based on two different modalities of whole-body electrostimulation (WB-EMS) with respect to a resistance-training program aimed at improving dynamic strength. Twenty-two subjects participated in this study: Thirteen male (age 25.2±2.8 years; height 1.78±0.1 m; body mass 72.8±6.4 kg; body fat 11.6±2.3%) and nine female (age 28.2±3.5 years; height 1.63±0.05 m; body mass 56.8±7.6 kg; body fat 19.1±4.7%). Participants were randomly assigned to three groups that underwent three different 6-week training programs: two modalities of WB-EMS, based on different electrical parameters (experimental), and circuit training with overloads (control). Force-velocity curves were calculated for each participant before and after treatment. All groups improved their level of strength and muscle power (paired sample t-Test, p<0.01; d>1) with a similar magnitude. No significant differences were observed between groups (two-way 2×3 Anova, p>0.05) at the end of the experimentation. This study suggests that WB-EMS might be considered as a valid and faster alternative – or an important complementary procedure – to a traditional overload-based resistance-training program for the development of the DS.
Dynamic Scoliosis Correction as Alternative Treatment for Patients with Adolescent Idiopathic Scoliosis: a Non-Fusion Surgical Technique
Authors: Trobisch Per David , Kobbe Philipp , Baroncini Alice 
Published: September 2019

AbstractAnterior dynamic scoliosis correction is an innovative non-fusion option in the treatment of patients with severe adolescent scoliosis. Growth modulation and sometimes intraoperative curve correction is achieved by convex insertion of segmental screws and a flexible polyethylene cord. The present review analyses and discusses the current literature and proposes a new treatment algorithm that is based on our own experience. Short term results are published for approximately 100 patients from different institutions. Fusion could be prevented in the vast majority of patients. Perioperative complication rate is very low but a few cases of cord rupture and overcorrection are reported. Anterior dynamic scoliosis correction has promising short term results but there is a paucity of literature and optimal criteria for the best candidate has yet to be defined.

Published: September 2019

Abstract
Purpose Currently, surgical training in the clinical scenario is limited by duty-hour restrictions as well as an increasing specialization within the numerous surgical fields. In such an environment, surgical training in subspecialties becomes both, more important and challenging. Against this background, purpose of the present study was to evaluate a new course format for advanced training in fracture treatment. In the studied course format, cadaveric wrist or elbow specimens with prefabricated fractures were used with the aim of improving the learning effect for the attendees. On these specimens, operative treatment with specific osteosynthetic implants was performed under radiographic control. We hypothesized that simulation in a complex scenario such as the one used in the studied course format leads to a subjectively better learning effect regardless of prior surgical experience.
Methods 205 participants in 16 courses between 2016 and 2018 were surveyed regarding their operative experience, previously attendances of trauma care trainings and subjective learning effect in the surveyed course and the trainings attended previously. Based on a ten-step scale, results in the subjective learning effect were compared between the investigated course and other trainings and to the individual operative experience.
Results The learning effect of the surveyed fracture courses was assessed with a median of 9/10 for the theoretical part and 10/10 for the practical part, significantly better than in trainings attended previously. The surveyed participants reported that they each performed 308 operations per year on average. Other course formats were attended significantly more frequent than courses on prefractured human specimens. The respondents reported a subjectively higher learning effect of the evaluated course concept in comparison to previously attended courses in practical and theoretical aspects.
Conclusions The reported innovative course format is an efficient concept for education in surgical trauma care, suited for more novice and advanced surgeons.

Abstract
Background Patient expectations are an issue which is attracting increased interest in outcome research for knee surgery procedures. So far, research into patient expectations has mainly focused on the procedure and postoperative functional improvements. The purpose of this study was to identify patient expectations in the perioperative setting.
Material and Methods This was a single-center prospective study. A 17-item questionnaire (ordinal answer scale) about patientsʼ perioperative expectations was developed and completed by patients undergoing elective joint-preserving knee surgery. The study covered a period of 3 months and included all patients consecutively undergoing knee surgery. Subgroup analysis was performed for gender, age and type of insurance.
Results 111 consecutive patients completed the questionnaire on admission. Significant preferences for one answer option were found for 13 out of 17 items. Patients considered it “unimportant” whether or not the physician wore a white coat during the consultation and “very important” that the first medical consultation after the patient was discharged from hospital was with the surgeon who had performed their operation. A concise explanation of the surgical procedure using images, talking to the surgeon the day before surgery and immediately after surgery, having their wound personally inspected by the surgeon, and, finally, the availability of the surgeon by phone were regarded as “important”. There were no differences in patient responses between the different subgroups.
Conclusion Patients expect a high personal commitment and availability of the surgeon during the entire perioperative setting, starting from the first consultation and continuing during follow-up examinations.
Neurosurgical Infections

Published: September 2019

AbstractPatients in the neurointensive care unit often undergo life-saving neurosurgical interventions that can be associated with serious complications. Infection is a common and sometimes fatal complication of such procedures. Infection may occur not only in the setting of major cranial and spinal surgery, but also with common minor procedures that utilize neurosurgical devices, such as placement of external ventricular drains, ventriculoperitoneal shunts, and deep brain stimulators. In this article, we review the epidemiology and microbiology of these infections, and discuss their general and procedure-specific risk factors and treatment options.

AbstractThe purpose of this study was to evaluate the correlation between magnetic resonance imaging (MRI) findings and demographic and clinical characteristics, response to treatment times, and recurrence rates of Sydenham's chorea (SC), the most common of the acquired pediatric choreas. The clinical and radiological findings of 12 patients presenting to the pediatric neurology clinic in the previous 4 years and diagnosed with SC on the basis of the modified Jones criteria were investigated retrospectively from the hospital files. In addition, we measured the maximum prefrontal cortex and basal ganglia (globus pallidus, putamen, and caudate nucleus) thicknesses in the axial plane from patients' cerebral MRIs and compared these values with prefrontal cortex and basal ganglia thicknesses of a healthy control group measured using the same technique. Patient and control groups' cranial and basal ganglia MRIs were found to be normal. However, patients' globus pallidus thicknesses were significantly lower than those of the healthy control group. Additionally, the globus pallidus values of patients with recurrent SC and a prolonged healing time were lower than average. However, we determined no significant difference in terms of prefrontal motor cortex, caudate nucleus, or putamen thicknesses between the patient and control groups. Low globus pallidus thicknesses in patients with SC may indicate atrophy associated with globus pallidus involvement. Further experimental and prospective and long-term studies are needed for a better understanding of the factors affecting the pathophysiology, recurrence, and healing time of SC.

Published: September 2019

Abstract
Radiation exposure and associated radiation risks are major concerns for fetal development for pregnant patients who undergo radiation therapy or diagnostic imaging procedures. In order to accurately estimate the radiation dose to the fetus and assess the uncertainty of fetal position and rotation, three hybrid computational fetus phantoms were constructed using magnetic resonance imaging (MRI) for each fetus model as a starting point to construct a complete anatomically accurate fetus, gravid uterus, and placenta. A total of 27 fetal organs were outlined from radiological images via the Velocity Treatment Planning System. The DICOM-Structure set was imported to Rhinoceros software for further reconstruction of 3D fetus phantom model sets. All fetal organ masses were compared with ICRP-89 reference data. Our fetal model series corresponds to 20, 31, and 35 weeks of pregnancy, thus covering the second and third trimester. Fetal positions and locations were carefully adapted to represent the real fetus locations inside the uterus for each trimester of pregnancy. The new series of hybrid computational fetus models together with pregnant female models can be used in evaluating fetal radiation doses in diagnostic imaging and radiotherapy procedures.

Published: September 2019

Abstract
Laboratory flume experiments were conducted in order to identify the temporal evolution of bed surface grain size properties by unsteady flows under zero sediment feeding conditions. Purposely designed sediment beds were composed by well-sorted gravel and sand, for each case, detailed data of the bed surface composition were collected. It is found that for all cases, the final sediment bed in the whole reach always shows a coarsening feature, and the coarsening process is much more developed near the inlet boundary. Further, the time variation of the percents of gravel and sand are observed increase or decrease alternately during the experiment and finally close to their initial percents. Besides, the experimental results show that there is no direct correlation between the flow unsteadiness and the coarsening degree of the final bed.

Abstract
In 2008, the normal pool level in front of the Three Gorges Dam was set at 175m, and afterwards the spatial distribution of sedimentation in fluctuating backwater region changed significantly. Moreover, with the operation of Xiluodu and Xiangjiaba Reservoirs in the upstream of Yangtze River, sedimentation in fluctuating backwater area has also changed accordingly. In order to analyse the characteristics of erosion and deposition in the fluctuating backwater area under new water and sediment conditions, Changshou Waterway which located in the middle section of the fluctuating backwater region is chosen as one typical waterway, and the measured data of Changshou Waterway is then investigated. Results show that: the riverbed of the middle section in the fluctuating backwater area is changed from silting to slight scouring, there is no accumulated deposition after the experimental impoundment of the Three Gorges Reservoir, and the riverbed deformation in the Zhongshui Moraine of the Changshou Waterway is much more sensitive to water and sediment conditions while the downstream curved channel near Matou Moraine is relatively stable.

Published: September 2019

Abstract
To achieve fast and efficient flood modelling for urban area, a two-dimensional cellular automata based model was developed and further coupled with a hydrological model. The model was implemented in parallel environments and tested by an analytical solution and a real word case. The analytical case results showed that the model is capable of simulating water-depth under a reasonable slope threshold and grid resolution condition using only a short computational time. Slope threshold and grid resolution are the two key factors affecting the computational efficiency and model accurcay. The introduction of the state update interval significantly improved the computational efficiency. In the case of the real world example, the results were also in reasonable range.In general, this model can be applied to rapid flood analysis for large urban areas.
Study on the influence of the sediment at reservoir bottom on dynamic damage of gravity dam

Published: September 2019

Abstract
Traditional linear elastic model or elastic-plastic DP model can hardly reflect the damage and failure law of the concrete and rock foundation when the tensile and compressive strengths exceed the limitation. Therefore, the concrete damage model is used to simulate the dynamic damage of gravity dam body. According to the similarity of concrete and rock mass materials, the damage model of concrete is extended to rock mass materials. The sediment at the bottom of reservoir is simulated by viscous and high density compressible fluid. Based on this, a multi-coupling simulation model is established, which can reasonably reflect the dynamic damage evolution process of the dam concrete and dam foundation rock mass. Based on the Koyna gravity dam project, taking the thickness of sediment at the bottom of the reservoir as a variable, FEM transient analysis is carried out in this paper. By comparing the damage areas of the model, the displacement of the key points of the dam body along the river and the energy dissipation index, the influence of different thicknesses of the sediment is quantified on the damage of the multi-coupling system of the gravity dam. The calculation results obtained are close to the actual earthquake damage, which verifies the feasibility and rationality of the calculation method. The results of the analysis also show that: the seismic damage of the gravity dam can be consistently reduced with the increase of the thickness of the reservoir bottom sediment. Compared with the dam body, the change of thickness of sediment has less influence on dam foundation damage.

Published: September 2019

Abstract
In this research, a method of artificial bee colony algorithm was proposed to optimize BP neural network parameters and then introduced to parameter inversion of geotechnical engineering. The method is based on the research and analysis of permanent deformation of geotechnical earthquake engineering and aimed at addressing the shortages of BP neural network which is slow to converge and may easily get minimum value. This method not only strengthens the global optimization ability of bee colony optimization algorithm, but also reflects the high accuracy of predicting nonlinear problems of BP neural network and the strong generalization ability. The proposed method also improves the prediction accuracy This new proposed method was validated by using the earthquake data of Zipingpu concrete faced rockfill dam in WenChuan earthquack. The results showed that this method can better solve the problem of permanent deformation parameters and can be extended to inversion predict of the same kind.

Authors: Ji Xiaolei 
Published: September 2019

Abstract
GDS triaxial test system was conducted to investigate the stress-strain relationship, strength characteristic and failure mechanism of Bermuda grass root-soil complex, and the effect of different root system distribution on strength of root-soil complex was also studied. The results indicate: ①the root system can improve the shear strength of soil and limit the deformation of that complex effectively. ②The contribution of the root system to the strength promotion of the root-soil complex is mainly reflected in the increase of cohesion. ③The strength increase of the root soil complex is related to the arrangement of roots in the soil. The effects are listed in the sequence as mixed placement> intersectant placement> vertical placement >horizontal placement >inclined placement. The research results provide theoretical support for the formation mechanism of the shear strength of the root-soil complex, which is meaningful to guide the selection of slope protection plants.
