SEISMIC METHOD MICROTREMOR REGISTRATION AS AN ELEMENT OF THE UNIQUE BUILDINGS NON-DESTRUCTIVE TECHNICAL REVIEW
Authors: Воскресенский М.Н.
Published: July 2024

Неразрушающий контроль зданий и сооружений предполагает отсутствие демонтажа, а также внешнего сильного источника упругих колебаний, способного нарушить целостность конструктива объекта. В данной работе в качестве источника сигнала используется микросейсмический шум. Для регистрации и обработки данных применяется аппаратно-программный комплекс отечественной разработки. Оценка частот собственных колебаний проведена при использовании спектрального анализа. Проведено вычисление виброскорости в точках измерения для определения уровня вибраций в помещении. Проанализирована уязвимость здания перед сильными упругими колебаниями. Приведена карта распределения коэффициента уязвимости. Объектом исследования выбрано уникальное строительное сооружение, дошедшее до нас с начала XIX века – церковь Иоанна Предтечи в городе Катав-Ивановск. Исследование проводилось летом 2019 года, с целью определить наличие внутренних повреждений строительной конструкции после произошедшего осенью 2018 года сильного регионального сейсмического события.

Non-destructive testing of buildings and structures assumes the absence of dismantling, as well as an external strong source of elastic vibrations that can disrupt the integrity of the structure. In this work, micro tremor is used as a signal source. For registration and processing of data, a hardware and software complex of domestic development is used. Evaluation of natural vibration frequencies was carried out using spectral analysis. The calculation of vibration velocity at the points of measurement is carried out to determine the level of vibration in the room. The vulnerability of the building to strong elastic vibrations is analyzed. The map of the distribution of the fragility coeffi cient is presented. The object of research is a unique building structure that has come down to us from the beginning of the 19th century - the Church of John the Baptist in the city of Katav-Ivanovsk. The research was conducted in the summer of 2109 to determine the presence of internal damage to the building structure after a strong regional seismic event in the fall of 2018.

Authors: Бахтерев В.В.
Published: July 2024

Изучен вещественный состав образцов дунитов и клинопироксенитов из Кытлымско- го гипербазитового массива Среднего Урала. Получены температурные зависимости электрического сопротивления в интервале температур 20‒900 ºC. Измерена величина магнитной восприимчивости образцов каппометром КТ-5с (в относительных единицах) и плотность (г/см3). Изготовлены прозрач- ные шлифы и описаны под микроскопом. Определены электрические параметры исследованных образ- цов (lgRₒ и Eₒ), установлен характер их распределения. По физическим параметрам и электрическим параметрам в области собственной проводимости (700–900 ºC) исследованные образцы разделены на четыре группы: дуниты и три группы клинопироксенитов. При этом для исследованных образцов клинопироксенитов оливинсодержащих слабо амфиболизированных и образцов оливинов выявлены одинаковые электрические параметры и установлен одинаковый характер их распределения. Таким образом, электропроводность при высоких температурах может быть надежным дополнительным не- зависимым параметром при исследовании дунитов и клинопироксенитов.

The material composition of dunite and clinopyroxenite samples from the Kytlym hyperbasite massif of the Middle Urals was studied. The temperature dependences of the electrical resistance in the temperature range of 20–900 °C are obtained. The magnetic susceptibility of the samples was measured with a KT-5c kappometer (in relative units) and the density (g/cm3). Transparent sections were made and described under a microscope. The electrical parameters of the studied samples (lgRₒ and Eₒ) were determined, and the nature of their distribution was established According to physical parameters and electrical parameters in the region of intrinsic conductivity (700–900 °C), the studied samples are divided into four groups: dunites and three groups of clinopyroxenites. At the same time, the studied samples of clinopyroxenites of olivine-containing weakly amphibolized and samples of olivines revealed the same electrical parameters and established the same nature of their distribution. Thus, electrical conductivity at high temperatures can be a reliable additional independent parameter in the study of dunites and clinopyroxenites.

ANALYSIS OF SEISMIC CATALOGS USING THE MODEL OF SPHERICAL DEFORMATION FRONTS
Authors: Овчаренко А.В.
Published: July 2024

Предложен и реализован алгоритм анализа сейсмических каталогов, который находит для каждого сейсмического события минимум четыре центра возбуждения деформационных импульсов. Импульсы деформаций распространяются в среде с некоторой, заранее неизвестной, скоростью. Сейсмические события оказываются, таким образом, в зоне интерференции деформационных волн, возбуждаемых этими начальными импульсами. Отыскивается минимальное число импульсов описывающих каталог, т.е. строится разложение сейсмических каталогов большого объема на систему динамических сферических фронтов. На первом этапе, по пробным парам сейсмических событий, находится начальное время зарождения сферического деформационного импульса и скорость его миграции через мантию и земную кору. На втором этапе проверяется соответствие всех событий сейсми- ческого каталога параметрам пробного деформационного фронта. Оптимальность начального времени и скорости миграции деформационного фронта оценивается по максимальному числу сейсмических событий, которые с априорно заданным допуском удовлетворяют уравнению движения пробного фронта. Начальные точки зарождения фронтов отыскиваются по сетке, покрывающей некоторую глубинную границу. По решению строятся три карты: карта условно возбужденной границы, например подошвы мантии, карта средней скорости миграции фронтов через мантию и земную кору, карта вре- мени возбуждения импульса на границе.

An algorithm for analyzing seismic catalogs is proposed and implemented, which finds at least four centers of excitation of deformation pulses for each seismic event. Deformation pulses propagate in the medium with a certain, previously unknown, velocity. Seismic events are thus in the zone of interference of deformation waves excited by these initial pulses. The minimum number of pulses describing the catalog is found, i.e. the decomposition of large-volume seismic catalogs into a system of dynamic spherical fronts is constructed. At the first stage, according to the test pairs of seismic events, the initial time of the origin of the spherical deformation pulse and the rate of its migration through the mantle and the Earth’s crust are found. At the second stage, the compliance of all events of the seismic catalog with the parameters of the test deformation front is checked. The optimality of the initial time and rate of migration of the deformation front is estimated by the maximum number of seismic events that satisfy the equation of motion of the test front with a priori given tolerance. The initial points of the origin of the fronts are found by a grid covering some deep boundary. According to the solution, three maps are constructed: a map of a conditionally excited boundary, for example, the soles of the mantle, a map of the average migration speed of fronts through the mantle and the Earth’s crust, a map of the pulse excitation time at the boundary.

Рассмотрены некоторые материалы Уральского эксперимента глубинного электромагнитного зондирования Земли с использованием в качестве энергетической установки магнитогидродинамического генератора. Произведено их сопоставление с аналогичными материалами метода магнитотеллурического профилирования. Показано, что уникальные полевые данные экспе- римента сильно осложнены геологическими помехами, влияние которых из-за огромной территории и недостаточной изученности поверхностных структур зоны его проведения, корректно устранить пока не удается. Сделано предположение о том, что с течением времени эти данные могут быть дополнены результатами других методов электроразведки, вновь обработаны и проинтерпретированы на современном техническом уровне.

Some materials of the Ural experiment of deep electromagnetic sounding of the Earth using a magnetohydrodynamic generator as an energy installation are considered. It is assumed that the unique fi eld data of the experiment is greatly complicated by geological interference. Due to the vast territory of its implementation, it is not yet possible to correctly take into account their infl uence, but over time these data can be supplemented with the results of other methods of electrical exploration, re-processed and reinterpreted at the modern technical level.

Рассмотрены методические приемы полевого эксперимента по изучению вклада галь- ванического возбуждения земных недр геомагнитными вариациями в суммарное естественное элек- тромагнитное поле диапазона короткопериодических колебаний. Произведено сравнение скважинных распределений отношений вертикальных составляющих электрической напряженности естественного и искусственно созданного полей к их горизонтальным составляющим. Сделано предположение о том, что доля вклада этого типа возбуждения Земли (по сравнению с индукционным возбуждением) на тер- риториях, относящихся к средним широтам, много меньше требуемой точности электроразведочных измерений, но, по мере продвижения на север, будет расти. Рассматриваемые методические приемы могут быть использованы при проектировании геофизических работ методами магнитотеллурического профилирования или зондирования в северных районах страны.

Methodological techniques of a fi eld experiment to study the contribution of galvanic excitation of the Earth’s interior by geomagnetic variations to the total natural electromagnetic fi eld of the short-period oscillations range are considered. The comparison of borehole distributions of the ratios of the vertical components of the electric intensity of the natural and artifi cially created fi elds to their horizontal components is made. It is assumed that the share of the contribution of this type of excitation (compared with induction excitation) in the territories belonging to the middle and low latitudes is much less than the required accuracy of electrical survey measurements, but, as we move north, it will grow. The considered methods can be used in the design of geophysical works by the methods of magnetotelluric profi ling or sounding in the northern regions of the country.

Published: July 2024

Для обеспечения как краткосрочного, так и долгосрочного прогноза землетрясений необходимо иметь адекватную модель геологической среды. В нашем случае предлагается многофазная контрастная модель, представляющая собой неоднородную пористую проницаемую влагонасыщенную среду в поле переменных тектонических напряжений. Считаем, что в зоне предполагаемого тектонического события в период его подготовки развивается неоднородное дилатирующее включение, которое представляет собой набор дилатирующих мезовключений, связанных между собой проницаемыми каналами. В зависимости от динамических условий на границе включений могут существовать недренажные условия. В этом случае в зоне включения возникает пониженное давление жидкости и на границе включения регистрируется дроссельный эффект (эффект Джоуля – Томсона). Тогда в зоне контакта наблюдается участок пониженной температуры, который может быть интерпретирован как предвестник тектонического события.

To provide both short-term and long-term earthquake prediction, it is necessary to have an adequate model of the geological environment. In our case, a multiphase contrast model is proposed, which is a heterogeneous porous permeable moisture-saturated medium in a fi eld of variable tectonic stresses. We believe that in the zone of the proposed tectonic event, during the period of its preparation, a heterogeneous dilatant inclusion develops, which is a set of dilatant meso-inclusions interconnected by permeable channels. Depending on the dynamic conditions, undrained conditions may exist at the boundary of the inclusions. In this case, a reduced fl uid pressure occurs in the switching zone, and a throttle effect (Joule-Thomson effect) is recorded at the switching boundary. Then, in the contact zone, there is an area of low temperature, which can be interpreted as a precursor of a tectonic event.

Published: July 2024

Рассмотрены результаты обработки синхронных наблюдений короткопериодических вариаций магнитотеллурического поля, полученных на ряде широтных пересечений Урала. Показано, что первичная часть этого поля на территории Среднего и Южного Урала практически однородна и магнитотеллурические методы геофизической разведки могут дать там вполне приемлемые геологические сведения.

The results of processing synchronous observations of short-period variations of the magnetotelluric fi eld obtained at a number of latitudinal intersections of the Urals are considered. It is shown that the primary part of this fi eld on the territory of the Middle and Southern Urals is almost homogeneous and magnetotelluric methods of geophysical exploration can give quite acceptable geological information there.

GEOTHERMAL MODELS OF LAYER-HETEROGENEOUS MEDIA. DIVISION OF THE FLOW INTO THE CORUS AND MANLE COMPONENTS
Authors: Ладовский И.В. , Бызов Д.Д.
Published: July 2024

Реализован метод решения задач сопряжения для уравнения Пуассона, позволяющий интерпретировать потенциальные поля (гравитационное и стационарное тепловое) на основе унифицированных сеточных алгоритмов. Выполнено послойное разделение теплового потока на аддитивные составляющие от источников земной коры и верхней мантий. Разработан численный алгоритм пересчета мантийной составляющей теплового потока от уровня земной поверхности к границе «кора-мантия» через неоднородную по теплопроводности слоистую среду. Мантийный тепловой поток, равно как и значения мантийных температур, служат индикатором скоростных неоднородностей по отражающим горизонтам верхней мантии. Дано сравнение послойных тепловых и гравитационных аномалий и установлена степень их стохастической близости. Использование данных о тепловом потоке позволяет значительно повысить геологическую информативность гравитационного и сейсмического моделирования. В измеренные значения градиента температуры и теплового потока для северных территорий введены палеоклиматические поправки. В осевой части Уральской геосинклинали удалось исключить отрицательную депрессию мантийной составляющей теплового потока, полученную по результатам геотермического моделирования; учет плейстоцен-голоценового потепления предшествующего межледникового палеоклиматического цикла приводит к положительным значениям теплового потока, пе- ресчитанного на границу «кора-мантия».

A method for solving conjugation problems for the Poisson equation is implemented, which makes it possible to interpret potential fi elds (gravitational and stationary thermal) based on unifi ed grid algorithms. The layer-by-layer separation of the heat fl ux into additive components from the sources of the earth’s crust and upper mantle has been carried out. A numerical algorithm has been developed for recalculating the mantle component of the heat fl ow from the level of the earth’s surface to the “crust-mantle” boundary through a layered medium inhomogeneous in thermal conductivity. The mantle heat fl ow, as well as the values of mantle temperatures, serve as an indicator of velocity inhomogeneities along the refl ecting horizons of the upper mantle. A comparison of layer-by-layer thermal and gravitational anomalies is given and the degree of their stochastic similarity is established. The use of heat fl ow data can signifi cantly increase the geological information content of gravity and seismic modeling. Paleoclimatic corrections were introduced into the measured values of the temperature gradient and heat fl ux for the northern territories. In the axial part of the Ural geosyncline, it was possible to exclude the negative depression of the mantle component of the heat fl ow, obtained from the results of geothermal modeling; taking into account the Pleistocene-Holocene warming of the preceding interglacial paleoclimatic cycle leads to positive values of the heat fl ow recalculated to the “crust-mantle” boundary.

В работе приведено описание технологии трехмерной интерпретации магнитных аномалий с учетом рельефа земной поверхности. Ключевые элементы технологии (выделения аномалий и вычисления поверхности источников) применены при исследовании намагниченных массивов Уральского орогена на территории 100х100 км, включающей Центрально-Уральскую и Тагильскую мегазоны. Высота горных хребтов на этом участке достигает 1000-1500 метров. Приведены результаты моделирования кровли источников магнитных аномалий, как учетом горного рельефа земной поверхности, так и для горизонтальной плоскости. Наиболее ярко отличия проявляются для моделей ультрабазит-базитовых комплексов массивов Платиноносного пояса Урала, выведенных на земную поверхность и образующих высокие горы.

The paper describes the technology for three-dimensional interpretation of magnetic anomalies taking into account the topography of the earth’s surface. Key elements of the technology (separation of anomalies and calculation of the source surface) were used in the study of magnetized massifs of the Ural orogen over an area of 100x100 km, including the Central Ural and Tagil megazones. The height of the mountain ranges in this area reaches 1000-1500 meters. The results of modeling the roof of sources of magnetic anomalies are presented, both taking into account the mountainous topography of the earth’s surface and for the horizontal plane. The differences are most pronounced for the models of ultramafi c-maphic complexes of the massifs of the Platinum Belt of the Urals, exposed on the earth’s surface and forming high mountains.

The study of the electrophysical characteristics of the site was carried out in the Verkhne-Sysertskaya soil dam according to experimental data of seasonal multi-frequency electrical soundings. Changes in the electrophysical characteristics of the bulk soil of the structure and the rocks at its base in different observation periods were determined by sections of specifi c electrical resistances, frequency effect and calculated on the basis of the spectral model of induced polarization of Cole-Cole polarizability and relaxation time of the medium. According to the results of seasonal studies, anomalous areas of the dam have been identifi ed, where soil moisture increases, its freezing and enhanced fi ltration are possible.

Over the past two decades, the organizational world has shown a particular interest in ethics. The majority of studies and research on the subject of ethics have been conducted within the framework of organizations, considered as a conventional environment; a few studies have, on the contrary, adopted a research framework in a unconventional context. This is the case with our current research on ethics in the academic and university environment in the context of Moroccan universities. As we shall demonstrate influence of the leader, or leadership can lead an individual to engage in deviant behavior as the ethical climate, which also serve as a reference for the behaviors to be adopted.
Student Voices: Challenges and Preferences with Technology-enabled Online Teaching and Learning in Higher Education
Authors: Singh Divya
Published: July 2024

The adaptation of the curriculum to incorporate cutting-edge technologies and human ethical values necessitates a careful, deliberate approach. A technological transition, pivotal for the future of education, is fraught with challenges but also with real chances for better human self-understanding. To appropriately understand the complexities and significance of this digital shift, Stadio Higher Education conducted a survey (STADIO SV Survey) to capture the voices of students on technology relevant to their social, learning, and teaching environments. After consolidating fundamental points as the methodology and the reliability of the survey, we proposed a descriptive analysis and a substantial study of the findings provided. Literature review and discussion of such important concepts as: choice of the technology, the nature of access, the computing skills needed, communication, contact and successful engagement permit, in a nutshell, the articulation of some very useful closing recommendations.

From Disposable Education to Acting in the World as a Human in the Time of AI
Authors: Class Barbara , De la Higuera Colin
Published: July 2024

This contribution presents two perspectives: one based on AI expertise and the other on the importance of knowledge as human knowledge. The later focuses on the purpose of education by revisiting Alexander von Humboldt’s concept of Bildung as the main purpose of education. Resisting the shifting to radically pragmatic models of education, without Bildung, in recent decades, in the Global North which develops a system of disposable education that focuses on training a workforce for the market. Concerned by the production of disposable knowledge and assessments, with the sole goal of achieving good grades and securing employment, we see Generative AI, as mirroring this functionalist and economist vision of society, revealing strongly the limits of this paradigm. This article first explains how automatic learning, the foundation of generative AI, works. Second, we shall discuss human deep learning, as opposed to surface learning showing how it is required to develop as a person in the Bildung perspective. Third, we highlight this first intuition that AI reveals the functioning of our societies and move beyond, with an art of questioning in philosophy.

Published: July 2024

Capturing atmospheric CO2 and converting it to valuable chemicals are important goals in contemporary science. We present here a simple, transition metal-free triazolylidene-borane adduct that can capture atmospheric CO2 and convert it to formate. Several key intermediates were isolated and characterized by a combination of multinuclear NMR spectroscopy, IR spectroscopy and single crystal X-ray diffraction. A first closed cycle for the conversion of CO2 to formic acid by using the aforementioned triazolylidene-borane compound is presented as well.
Theoretical Insight into the Fluorescence Spectral Tuning Mechanism: A Case Study of Flavin-dependent Bacterial Luciferase
Authors: Fu Xiaodi , DIAO WENWEN , Luo Yanling , Liu Yajun , Wang Zhanfeng
Published: July 2024

Bioluminescence of bacteria is widely applied in biological imaging, environmental toxicants detection, and many other situations. Understanding the spectral tuning mechanism not only helps explain the diversity of colors observed in nature, but also provides principles for bioengineering new color variants for practical applications. In this study, time-dependent density functional theory (TD-DFT) and quantum mechanics and molecular mechanics (QM/MM) calculations have been employed to understand the fluo-rescence spectral tuning mechanism of bacterial luciferase, with a focus on the electrostatic effect. The spectrum can be tuned by both the homogeneous dielectric environment and oriented external electric fields (OEEFs). Increasing solvent polarity leads to a redshift of the fluorescence emission maximum, λF, accompanied by an increase in density. In contrast, applying an OEEF along the long axis of the isoalloxazine ring leads to a significant red- or blue-shift in λF, depending on the direction of the OEEF, but with negligible changes in its intensity. The effect of polar solvents is directionless, and the red-shifts can be attributed to the larg-er dipole moment of the S1 state compared to the S0 state. However, the effect of OEEFs directly correlates with the difference dipole moment between the S1 and S0 states, which is directional and determined by the charge redistribution upon excitation. Moreover, the electrostatic effect of bacterial luciferase is in line with the presence of an internal electric field (IEF) pointing in the negative X direction with a magnitude of ca. 30 MV/cm. Finally, key residues that contribute to this IEF and strategies for modu-lating the spectrum through site-directed point mutations are discussed.

Physical adsorption is one of the most widely used techniques to characterize porous materials because of being reliable and able to assess micro- and mesopores within one approach. However, challenges and open questions persist in characterizing disordered and hierarchically structured porous materials. This study introduces a pore network model aiming to enhance the textural characterization of nanoporous materials. Our model, based on percolation theory on a finite sized Bethe lattice, includes all mechanisms known to contribute to adsorption hysteresis in mesoporous pore networks during capillary condensation and evaporation. The model accounts for delayed and initiated condensation during adsorption as well as equilibrium evaporation, pore blocking and cavitation during desorption. Coupled with dedicated non-local-density functional theory (NLDFT) kernels, the proposed method provides a unified framework for modeling the entire experimental adsorption-desorption isotherm, including desorption hysteresis scans. The applicability of the method is demonstrated on a selected set of nanoporous silica materials exhibiting distinct types of hysteresis loops (types H1, H2a, H1/H2a and H5), including ordered mesoporous silica networks, i.e, KIT-6 silica, hybrid SBA-15/MCM-41 silica with plugged pores, but also two disordered silica pore networks, i.e., a hierarchical meso-macroporous monolith and porous Vycor glass. For all materials, good correlation is found between calculated and experimental primary adsorption and desorption isotherms as well as desorption scans. The model allows to determine key pore network characteristics such as pore connectivity and pore size distributions as well as a parameter correlated with the impact of pore network disorder and corresponding effects on the adsorption behavior. The versatility and enriched textural insights provided by the proposed novel network model allow for a comprehensive characterization previously inaccessible, and hence will contribute to a further advancement in the textural characterization of novel nanoporous materials. It has the potential to provide important guidance for the design and selection of porous materials for optimising various applications, including separation processes (such as chromatography), heterogeneous catalysis, gas- and energy storage.

The rheological properties of the electrode slurry significantly influence the manufacturing process of solid-state batteries (SSBs), affecting coating quality and the resulting cathode microstructure. The correlation between slurry attributes and final electrode characteristics is analyzed using particle size and solid content as key metrics. The performed coarse-grained molecular dynamics simulations closely fit experimental viscosity, indicating the model's suitability for predicting slurry behavior. Then the microstructural properties of the dry and calendered electrodes are calibrated with the experiments. The simulation workflow is fitted completely using only two sets of force fields, one for the slurry and the other for the dry state of the electrode. The effective electronic conductivities are contingent on the particle size, without showing significant limitation on cathode rate capabilities. This comprehensive study highlights the intricate interplay between slurry solid content, microstructure design, and manufacturing processes in optimizing SSB performance. Consistent slurry characteristics are crucial for uniform electrode coating while optimizing particle size and solid content improves electrode porosity. The findings provide valuable insights for enhancing SSB design and manufacturing processes for the adaptation of already established scaling up technologies.
Statistical distribution of static stress resolved onto geometrically-rough faults
Authors: Maurer Jeremy
Published: July 2024

The in-situ stress state within fault zones is technically challenging to characterize, requiring the use of indirect methods to estimate. Most work to date has focused on understanding average properties of resolved stress on faults, but fault non-planarity should induce spatial variations in resolved static stress on a single fault. Assuming a particular stochastic model for fault geometry (band-limited fractal) gives an approximate analytic solution for the probability density function (PDF) on fault stress that depends on the mean fault orientation, mean stress ratio, and roughness level. The mean stress is shown to be equal to the planar fault value, while deviations are described by substituting a second-order polynomial expansion of the stress ratio into the inverse distribution on fault slope. The result is an analytical expression for the PDF of shear-to-normal stress ratio on 2-D rough faults in a uniform background stress field. Two end-member distributions exist, one approximately Gaussian when all points on the fault are well away from failure, and one reverse exponential, which occurs when the mean stress ratio approaches the peak. For the range of roughness values expected to apply to crustal faults, stress deviations due to geometry can reach nearly 100% of the background stress level. Consideration of such a distribution of stress on faults suggests that geometric roughness and the resulting stress deviations may play a key role in controlling earthquake behavior.

Risiko und Unsicherheit in der modernen islamischen Praxis : Das Versicherungswesen im Iran von den Anfängen bis in die Gegenwart
Authors: Forian-Szabo Viktor
Published: July 2024

The principle of insurance as a calculable assumption of risk emerged in Europe as early as the late Middle Ages. Despite their high economic relevance, however, they were not fully institutionalized in law until the 19th century. In the Islamic world, on the other hand, insurance was virtually unknown until the time of colonialism. As a Western cultural import, it was then viewed with extreme skepticism and was the subject of heated debate. The “Islamic revival” of the 1970s in particular gave these debates new impetus. Viktor Forian-Szabo traces the development of the insurance industry in the specific context of the Islamic Republic of Iran. Drawing on interdisciplinary perspectives and methods, he succeeds in identifying the key factors that characterize the establishment of the commercial insurance industry in Iran's particular political, legal, economic and climatic environment.

Published: July 2024

Objective: To evaluate the clinical efficacy of bone traction combined with small splint external fixation in treating tibiofibular fractures. Methods: 378 patients with tibiofibular fractures who were treated in the Department of Orthopedics of our hospital from January 2019 to January 2023 were selected as study subjects. According to the specific conditions of the patients and the indications for surgery, they were divided into the observation group (bone traction combined with small splint external fixation) and the control group (conventional plaster fixation), with 189 cases in each group. Both groups of patients immobilized the affected limb as instructed by their doctors and were treated with oral anti-inflammatory and pain-relieving medications. The healing of the fractures was monitored using imaging techniques such as X-rays, computed tomography scans, and magnetic resonance imaging, while postoperative complications were also recorded. Results: The incidence rate of non-healing in the control group (7.41%) was significantly higher than that in the observation group (1.06%) (P < 0.05); the complications in the observation group were mainly three cases of limb deformity, three cases of pressure sores, and four cases of skin necrosis, with a total of 10 cases and an incidence rate of 5.29%; while in the control group, there were three cases of fracture nonunion, nine cases of skin necrosis, seven cases of pressure sores, and three cases of limb deformity, with a total of 22 cases and an incidence rate of 5.29%, the difference between the two groups was statistically significant (χ2 = 4.916, P = 0.027). Conclusion: Bone traction combined with small splint external fixation has shown remarkable efficacy in the treatment of tibiofibular fractures, which can not only quickly stabilize the fracture end, reduce pain, and promote fracture healing, but also reduce the occurrence of complications and shorten the treatment period.
