The object of the study: clinical effect of intramedullary blocking osteosynthesis of fractures of the bones of the extremities without reaming of the bone marrow canal. The problem to be solved: determination of the influence of surgical technology of intramedullary blocking osteosynthesis of bone fractures without reaming of the bone marrow canal on the qualitative and anatomical and functional results of treatment. Main scientific results. The term of fusion of bone fragments in complete groups (including all localizations) in the group of patients who underwent surgery with reaming of the bone marrow canal was 4.21±0.46 months, while in the group without reaming of the canal it was much shorter – 3.47±0.51 months Faster functional recovery of the limbs was also observed in cases that precluded bone marrow reaming – 96 % of good and 4 % satisfactory scores were obtained (80 % good and 20 % satisfactory in bone marrow reaming). The technology of closed intramedullary blocking osteosynthesis without reaming of the bone marrow can optimize the time of fusion of bone fragments and get 91 % good and 9 % satisfactory results. Its effectiveness is to reduce the number of satisfactory treatment results by 19 %, the absence of unsatisfactory and increase the share of good results by 23 %. The area of practical use of research results: clinics of traumatological profile of different levels, in which surgical treatment of fractures of the bones of the extremities are done. An innovative technological product: technology of closed intramedullary blocking osteosynthesis without reaming of the bone marrow canal. The area of application of an innovative technological product: clinical practice of using the technology of closed intramedullary blocking osteosynthesis without reaming of the bone marrow canal.

Summary. The main condition for preventing complications of intramedullary blocking osteosynthesis of long bones is following the tactical and technical principles of osteosynthesis and conscious rejection of such surgical techniques and manipulations that can lead to disturbances of the course of reparative processes of bone tissue. Objective. On the basis of the study and summary of the identified complications of intramedullary blocking osteosynthesis of diaphyseal fractures of bones of limbs, to determine ways to prevent complications of the reparation. Materials and Methods. The results of treatment of 403 patients who underwent intramedullary blocking osteosynthesis of the femur, tibia and humerus types A1-A3, B1–B3 and C2 by AO/ASIF were studied and analyzed. Results. Analyzing the technological complications that we have divided, depending on the consequences they led to, early (up to 2 weeks after surgery), late (2 weeks after surgery) and reparative, we found that the most common technological mistakes were incorrect preoperative planning and disruption of technology and surgery, which in 21.6% of cases led to instability of bone fragments in the fracture area, and the absence or disruption of recovery and rehabilitation of patients, which occurred in 26.3% of cases. Disorders of osteosynthesis technology, namely, significant intra-operative traumatization of bone fragments and soft tissues, and non-eliminated soft tissue interposition resulted in inappropriate consolidation of bone fragments in 39% and 13%, respectively. The main cause of reparative complications was bone marrow drilling, which was performed for 56% of the patients with delayed consolidation of bone fragments, 56.3% of the patients with false joints, and 48% of the patients with bone fractures. Conclusions. Strict following the tactical and technical principles of intramedullary blocking osteosynthesis and rejection of bone marrow drilling without indications will reduce the incidence of bone dysregeneration. The study of the effect of bone marrow drilling on reparative bone regeneration in intramedullary blocking osteosynthesis is actual and needs further deep analysis.

Abstract. Introduction The problem of complications after surgical treatment of pertrochanteric fractures in elderly patients is relevant and far from a solution. Materials and methods The retrospective study was based on the analysis of the results of treatment of 129 patients with pertrochanteric femoral fractures (average age 76 years). All fractures in the early time from trauma were fixed with two types of cephalomedullary nails, either dynamic or static. All patients could not limit the load on the operated limb after surgery because of different reasons. Results The results of treatment were evaluated in 109 patients after one year. In dynamic cephalomedullary fixator group (59 patients), there were 7 orthopedic complications with a functional Harris scale result of 68 points (range, 26 to 94 points). In static cephalomedullary fixator group (50 patients), there were 14 orthopedic complications with a functional Harris score of 56.5 points (range, 15 to 92 points). Discussion Higher results of treatment in the group of dynamic fixator in the condition of full-weight bearing on the operated limb may be associated with the possibility of dynamization of the part of fixator in response to bone resorption in the contact area of bone fragments. The use of dynamic cephalomedullary fixators instead of static ones for treatment of pertrochanteric femoral fractures in elderly patients exercising full weight-bearing leads to a decrease in orthopedic complications (from 28 to 11.9 %) and improves the functional results of treatment.

Object of research: technology as a component of human social life in the context of the postmodern era. Investigated problem: determination of the features of the influence of technological processes on a person of the postmodern era, as a result of which the natural is replaced by an artificial one and the images of both man and the Earth change. Main scientific results: the study of the contradictions of the process of technologization in the postmodern era made it possible to determine the transformation processes taking place in the life of a person and society. This defines social reality, represented by various markers, among which technology is gaining in importance. The latter act as a composite, which provides new opportunities for determining the relationship between the elements of the "world - man - culture" system. It is not only about the emergence of new human figures, among which the technological man (Homo Technologicus) occupies a prominent place, but also the emergence of a new image of the Earth, where the natural is replaced by the technological. The scope of practical use of the research results: the research results can be used in teaching normative courses "Philosophical Anthropology", "Ethics", "Sociology" for students and undergraduates, graduate students of humanitarian and natural faculties. Innovative technological product: the plurality of existing technologies (economic, medical, educational, humanitarian, etc.) destroys the new European concept of culture and man, which were provided within the framework of the monoparadigm. The anthropological dimension of technology testifies that the latter are beginning to act as a condition for human expansion. This situation has a significant impact on the existentials of human existence. The scope of using the innovative technological product: the intensive technologization of the last decades not only provokes environmental risks and changes the state of the Earth, the natural reality of the Earth is replaced by an artificial one, which allows to conclude that the Earth is formed by a technological one.

Background. Fractures of the bones of the facial skeleton, in particular the midface area, are one of the most frequent reasons for patients to apply to maxillofacial inpatient care, not only in Ukraine but also abroad. Along with more modern treatment technologies (osteosynthesis using titanium miniplates and minigrid for fixation bone fragments), methods of repositioning of fragments with subsequent tamponade of the maxillary sinus with iodoform tampon and without tamponade and fixation of fragments are used. A certain group of patients is treated conservatively, which is associated with their reluctance to undergo surgery, minimal displacement of fragments or minimal cosmetic and functional impairments. The purpose of the study. Comparative evaluation of the results of treatment of patients with fractures of the midface area by repositioning the fragments of the zygomatic-orbital complex without fixating the fragments and their subsequent fixation by tamponade of the maxillary sinus with iodoform tampon. Object and methods of research. The comparison was made of the results of treatment of 70 patients with fractures of the midface area, among which 13 patients were treated by the method of repositioning fragments of the zygomatic-orbital complex (ZOC) without fixation and without maxillary sinus tamponade, 29 patients underwent repositioning of ZOC fragments with subsequent fixation of fragments with iodoform tampon – the tamponade of the maxillary sinus was performed on the affected side. For comparison, the results of conservative treatment of 28 patients with fractures of the midface area were used. Results. It was found that the reliable (χ2=11.43; p<0.05) majority of patients (64%) sought treatment within 0-3 days after injury. 83-89% of patients who underwent repositioning of the fragments had fresh small-fragment fractures. The reliable (χ2=11.43; p<0.05) majority of them simultaneously had 3-4 sites of bone fractures of the midfacearea, hemosinus of varying degrees and paresthesia in the infraorbital area. In the majority of patients who underwent repositioning of bone fragments with and without tamponade (85% and 93%, respectively), the final displacements ranged from 3.1 to 6 mm. In patients treated conservatively, in most cases (93%) the displacements were greater than 3.1 mm, which remained after treatment. Conclusion. In the majority of patients treated with the studied methods, in the long term, the displacement of bone fragments remained, which had functional and cosmetic consequences. In all studied groups, a certain cosmetic effect was achieved over time, as evidenced by a reliable (χ2=160.9; p=0.00000) decrease in the indicator by the visual analogue scale .

The object of research: the process of membrane concentration of buttermilk using methods of removing the polarizing layer on the membrane surface. Investigated problem: determination of the effectiveness of methods for eliminating the polarization layer on the membrane surface during membrane concentration of buttermilk. Main scientific results: The results of experimental studies on methods of removing the polarization layer to increase the productivity of ultrafiltration equipment in the process of membrane concentration of buttermilk are presented. Mathematical models are proposed based on the regression equation of a factorial experiment using the elimination of the polarization layer on the membrane to determine the rational operating parameters of the membrane concentration of buttermilk. These parameters were determined: pressure – 0.4 … 0.5 MPa, buttermilk temperature – 40 … 50 °С, speed of pulsating flows – 1.5 … 1.7 m/s, frequency of bubbling of raw materials – 0 , 10 … 0.15 min-1, bubbling pressure – 0.56 … 0.58 MPa. A comparative analysis of the application of the method of vibrational mixing and bubbling of separated non-fat dairy raw materials to eliminate the formation of a polarization layer on the surface of membranes in the process of membrane concentration is presented. Based on the obtained quantitative and qualitative characteristics of the ultrafiltration products, it can be seen that vibrational mixing and bubbling of the processed buttermilk equally intensify the process of membrane concentration of buttermilk. The area of practical use of the research results: enterprises of the dairy industry of the food industry, engaged in waste-free processing of dairy raw materials and its by-products. An innovative technological product: devices for reducing the polarization layer, allowing to increase the performance of membranes in the process of membrane concentration of buttermilk. Scope of application of the innovative technological product: waste-free processing of dairy raw materials at dairies and dairy plants and other food industry enterprises.

The object of research: the procedural order of fiscal and accounting regulation of revenues from export agricultural products (export receipts, the export duty). Investigated problem: obtaining stable and repetitive connection between the accounting part, the fiscal part of the regulation and exports of agricultural goods with possibility of improvement. The main scientific results: it is revealed that the first stage of fiscal-accounting regulation of exported agricultural products is transactions’ accounting on accounts. It should be noted that, after the abolition of the mandatory sale in Ukraine, there is no need to apply the distributive account in export of agricultural products. It will help to reduce the time of enrollment the currency and its using by exporters for their needs. It is determined too, that the second stage of the regulation is the export receipts and revenues from the export duty. Moreover, using economic (mathematical) modeling, based on correlation-regression analysis, it is illustrated positive effects for reducing of export duty rates on revenues from export agricultural products in Ukraine. The area of practical use of the research results: Government of Ukraine in formation of export strategy, and exporters – in the context of accounting. Innovative technological product: the regulation technology of the cyclical accounting and fiscal parts in agricultural exports with using modeling econometric analysis for determination of direction of its development. Scope of the innovative technological product: Ukraine’s Government practice in using mathematic modeling for determination of trends of agricultural exports.

COMPLICATIONS IN BLOCKING INTRAMEDULLARY OSTEOSYNTHESIS (review) Mansyrov A.B. Ogly, Lytovchenko V., Berezka M., Garyachiy Ye., Rami A.F. Almasri Treatment of diaphyseal bone fractures is a complicated, controversial and ambiguous task. Blocking intramedullary osteosynthesis, which became the standard of treatment, is also not perfect and accompanied by a number of complications. The reasons for their occurrence are connected both with defects in the organization of treatment of patients, and with tactical mistakes, the definition, generalization and prevention of which became the purpose of our study. It was found that typical tactical mistakes were: use of the method against the indications, non-compliance with the technology of blocking intramedullary osteosynthesis and the use of unsubstantiated and inadequate "proprietary methods", making their own "modifications" during the surgery and changing the course of operative intervention, excessive drilling of the bone marrow canal, significant intraoperative traumatism of bone fragments and surrounding soft tissues, incorrect type of lock or timely unfulfilled dynamization, lack of consistency and restorative and rehabilitative treatment. But the most negative effect on the anatomical recovery of the bone and functional recovery of the extremity was the bone marrow canal drilling, performed without the corresponding indications and technical disadvantages. It is obvious that the violation of the endostosis of the endostal negative effect on the reparative capabilities of bone tissue, inhibits the process of bone grafting and delay recovery. Therefore, there is no doubt that the further study of the effect of bone marrow duct penetration in the course of reparative osteogenesis is relevant and appropriate. Key words: blocking intramedullary osteosynthesis, tactical mistakes, fracture, long bones, drilling.   Резюме. УСКЛАДНЕННЯ ІНТРАМЕДУЛЯРНОГО БЛОКУЮЧОГО ОСТЕОСИНТЕЗУ (огляд) Мансиров А.Б. Огли, Литовченко В.О., Березка М.І., Гарячий Є.В., Рами A.Ф. Аль-масри Лікування діафізарних переломів кісток кінцівок є складним, спірним та неоднозначним завданням. Інтрамедулярний блокуючий остеосинтез, який став стандартом їх лікування, також не позбавлений недоліків і супроводжується низкою ускладнень. Причини їх виникнення пов'язані як з дефектами організації лікування хворих, так і з тактичними помилками, визначення, узагальнення та попередження яких і стали метою нашого дослідження. Виявлено, що типовими тактичними помилками є використання методу проти показань, недотримання технології інтрамедулярного блокуючого остеосинтезу та використання необгрунтованих та неадекватних «авторських» методик, внесення власних «поправок» під час виконання операції та зміна ходу оперативного втручання, надлишкове розсвердлювання кістково-мозкового каналу, значна інтраопераційна травматизація кісткових уламків та оточуючих м'яких тканин, невірний тип блокування або вчасно невиконана динамізація, відсутність послідовності у відновному та реабілітаційному лікуванні. Але найбільш негативний вплив на анатомічне відновлення кістки та функціональне відновлення кінцівки мало розсвердлювання кістково-мозкового каналу, виконане без відповідних на те показань і з технічними недоліками. Очевидно, що порушення цілосності ендосту негативно впливає на репаративні можливості кісткової тканини, гальмує процес кісткового зрощення та відтерміновує одужання. Тому не викликає сумнівів, що подальше вивчення впливу розсвердлювання кістково-мозкового каналу на перебіг репаративного остеогенезу є актуальним та доцільним. Ключові слова: інтрамедулярний блоковий остеосинтез, тактичні помилки, перелом, довга кістка, розсвердлювання.   Резюме. ОСЛОЖНЕНИЯ ИНТРАМЕДУЛЛЯРНОГО БЛОКИРУЮЩЕГО ОСТЕОСИНТЕЗА (огляд) Мансыров А.Б. Оглы, Литовченко В.А., Березка Н.И., Гарячий Е.В., Рами A.Ф. Аль-масри Лечение диафизарных переломов костей конечностей является сложной, спорной и неоднозначной задачей. Интрамедуллярный блокирующий остеосинтез, который стал стандартом их лечения, также имеет недостатки и сопровождается рядом осложнений. Причины их возникновения связаны как с дефектами в организации лечения больных, так и с тактическими ошибками. Поэтому целью исследования было их определение, обобщение и пути предупреждения. Установлено, что типичными тактическими ошибками были: применение метода без показаний, нарушение его технологии и применение необоснованных и неадекватных «авторских» методик, внесение собственных «поправок» во время выполнения операции и изменение хода оперативного вмешательства, избыточное рассверливание костно-мозгового канала, значительная интраоперационная травматизация костных отломков и окружающих мягких тканей, неправильно выбранный тип блокирования или не вовремя выполненная динамизация, отсутствие преемственности в восстановительном и реабилитационном лечении. Однако наиболее негативное влияние на анатомическое восстановление кости и функциональное восстановление конечности имело рассверливание костно-мозгового канала, выполненное без соответствующих показаний и с техническими огрехами. Очевидно, что нарушение целостности эндоста негативно влияет на репаративные возможности костной ткани, тормозит процесс костного сращения и отдаляет выздоровление.Поэтому не вызывает сомнений, что дальнейшее изучение влияния рассверливания костно-мозгового канала на течение репаративного остеогенеза является актуальным и целесообразным. Ключевые слова: интрамедуллярный блокирующий остеосинтез, тактические ошибки, перелом, длинная кость, рассверливание.

Modern concept for the treatment of long bones fractures complicated by purulent infection is presented. The main principles of this concept are the determination of volume and pattern of bone and soft tissue injury, radical debridement, stable bone fragments' fixation, use of primary and early reconstructive-restorative operations for substitution of bone and soft tissue defects. Treatment results for 268 patients (289 extremity segments) have been analyzed. Applied method of grouping patients with complicated long bone fractures by the pattern and volume of injury enables to determine the volume of debridement, terms and steps of osteosynthesis and reconstructive-plastic operations. Good and satisfactory results have been achieved in 88% of cases.
