Peculiarities of transosseous osteosynthesis with pin-rod external fixation devices at treatment of various intraarticular fractures in the area of the knee joint are presented. Analysis of treatment outcomes for 108 patients with 110 fractures (18 fractures of femoral condyles and 92 fractures of tibial condyles) was performed. Excellent and good results were achieved in 83 (75.4%) cases. In polysegmental and impression-compression fractures of femoral and tibial condyles the treatment results were most often only satisfactory or unsatisfactory that was accounted for the severity of injury with massive destruction of the articular surfaces.

Relevance. Knee contractures have an impact on quality of life and are also a common cause of disability. The use of external fixation devices has a certain place in the treatment of this pathology.Purpose. Using the world literature, to identify the modern position, problems, and prospectives of external fixation in the treatment of knee flexion and extension contractures in adult patients.Methods. EMBASE, Medline, Google Scholar, PubMed, e-LIBRARY, and Cyber resources were used. The analysis included publications relative treatment of knee joint stiffness using external fixation in patients over 18 years old, regardless of gender. At analysis several criterial were used: frame ability to provide movements in the knee joint according with its natural kinematics (biomechanics), stable fixation of the femur and tibia, and possibility inserting wires and halfpins in projection of Reference Positions (RP).Results. The devices used in the treatment of knee joint contractures in adult patients were conditionally divided, depending on the type of hinge, into 4 groups: non-hinged, uniaxial, reproducing, and virtual. It has been established that only orthopedic hexapods, based on virtual hinge, can meet all of the criteria mentioned above. However the technology of any orthopedic hexapod hardware and software usage for the treatment of contractures of the knee joint, was not developed till now.Conclusion. The necessity of developing hex-based technology for treatment patients with knee joint contractures was justified by world literature review. Hexapod hardware must provide possibilities of any inclination angle of any ring, and struts fixation not only to base and mobile rings, but to stabilizing as well. Software should be equipped with multi-total residual option. Ortho-SUV Frame (OSF) meets these requirements.

Introduction. Use of arthroscopically assisted reduction of bone fragments in comminuted intraarticular fractures of the distal radius (DR) remains ambiguous.The purpose of the study was to determine the expediency and efficacy of arthroscopy in surgical treatment of comminuted DR frac- tures especially under conditions of wrist joint (WJ) external fixation.Patients and methods. Sixty eight patients (mean age 38±14.1 years) with comminuted intraar- ticular DR fractures (type B3-C3 by AO/ASIF) were operated on. In 34 out of them arthroscopic support of osteosynthesis was used. Treatment results were assessed in 3, 6 and 12 months by DASH questioner, X-ray examination data, grip strength and range of motion in WJ.Results. It was stated that WJ arthroscopy improved the diagnosis of joint injuries (injury of tri- angular fibro-cartilage complex was diagnosed in 29 (83.5%), scapholunate ligament - in 12 (35.5%), lunotriquetral ligament - in 4 (11.8%) cases) and the quality of bone fragments reposition (displacement of intraarticular fragments over 1 mm after primary reposition was arthroscopically diagnosed in 21 (61.8%) cases, statistically significant improves the early postoperative (first 3 months after surgery, p<0.05) but did not affect the long term treatment results.

The aim of the paper is to conduct a comparative assessment of bowel decompression methods in operations on toxic widespread peritonitis. Materials and Methods. The authors examined 162 patients with widespread peritonitis of various etiologies. Using generally accepted methods, they compared treatment results using one of the three methods of intestinal decompression: cecostomy, nasointestinal intubation, and cecostomy with intubation of the small intestine. Results. It was detected that in case of small intestine intubation through the cecostomy (in comparison with other methods), intra-abdominal pressure returned to normal on the 2nd day, and in case of cecostomy or nasointestinal intubation – on the 5th and 7th day, respectively. Also, decrease in intoxication indicators was observed 2 days earlier than usual. Conclusion. Intubation of the small intestine through the cecostoma provides the most adequate intestinal decompression in patients with advanced toxic peritonitis. Early normalization of intra-abdominal pressure in patients with advanced toxic peritonitis improves treatment outcomes. Keywords: widespread peritonitis, intestinal decompression. Цель – сравнительная оценка способов декомпрессии кишечника при операциях по поводу распространённого перитонита в токсической стадии. Материалы и методы. Наблюдали 162 пациента с распространённым перитонитом различной этиологии. С использованием общепринятых методик сравнивались результаты лечения при применении одного из трёх способов декомпрессии кишечника: цекостомии, назоинтестинальной интубации и наложения цекостомы с интубацией тонкой кишки. Результаты. Установлено, что при использовании интубации тонкого кишечника через цекостому, в сравнении с другими применявшимися нами способами, внутрибрюшное давление нормализовалось на второй день, а при использовании цекостомии или назоинтестинальной интубации – на 5-й и 7-й дни соответственно. Также на 2 сут раньше происходило снижение показателей интоксикации. Выводы. Наиболее адекватную декомпрессию кишечника у пациентов с распространённым перитонитом в токсической стадии обеспечивает интубация тонкого кишечника через цекостому. Ранняя нормализация внутрибрюшного давления у пациентов с распространённым перитонитом в токсической стадии позволяет улучшить результаты лечения. Ключевые слова: распространённый перитонит, декомпрессия кишечника.

Background:Pain is a major debilitating symptom of knee osteoarthritis (OA). However, the extent of joint damage in OA does not correlate well with the severity of pain. The mechanisms that govern OA pain are poorly understood. Immune cells infiltrating nervous tissue may contribute to pain maintenance.Objectives:Here we investigated the role of macrophages in the initiation and maintenance of OA pain.Methods:Knee joint damage was induced by an unilateral injection of mono-iodoacetate (MIA) or after application of a groove at the femoral condyles of rats fed on high fat diet. Pain-like behaviors were followed over time using von Frey test and dynamic weight bearing. Joint damage was assessed by histology. Dorsal root ganglia (DRG) infiltrating immune cells were assessed over time using flow cytometry. To deplete monocytes and macrophages, Lysmcrex Csfr1-Stop-DTR were injected intrathecal or systemically with diptheria toxin (DT).Results:Intraarticular monoiodoacetate injection induced OA and signs of persistent pain, such as mechanical hyperalgesia and deficits in weight bearing. The persisting pain-like behaviors were associated with accumulation of F4/80+macrophages with an M1-like phenotype in the lumbar DRG appearing from 1 week after MIA injection, and that persisted till at least 4 weeks after MIA injection. Macrophages infiltrated DRG were also observed in the rat groove model of OA, 12 weeks after application of a groove at the femoral condyles. Systemic or local depletion of DRG macrophages during established MIA-induced OA completely ablated signs of pain, without affecting MIA-induced knee pathology. Intriguingly when monocytes/macrophages were depleted prior to induction of osteoarthritis, pain-like behaviors still developed, however these pain-like behaviors did not persist over time.In vitro,sensory neurons innervating the affected OA joint programmed macrophages into a M1 phenotype. Local repolarization of M1-like DRG macrophages towards M2 by intrathecal injection of M2 macrophages or anti-inflammatory cytokines resolved persistent OA-induced pain.Conclusion:Overall we show that macrophages infiltrate the DRG after knee damage and acquire a M1-like phenotype and maintain pain independent of the lesions in the knee joint. DRG-infiltrating macrophages are not required for induction of OA pain. Reprogramming M1-like DRG-infiltrating macrophages may represent a potential strategy to treat OA pain.Acknowledgments:This project has received funding from the European Union’s Horizon 2020 research and innovation programme under the Marie Sklodowska-Curie grant agreements No 814244 and No 642720.

After alluding to the comparatively superficial manner in which physiologists, with the exception of the brothers Weber, have hither-to investigated the structure and movements of the joints, the author gave an abstract of the general results which he had formerly obtained in an examination of the knee-joint, made with reference to Meyer's valuable observations. He had found that, as stated by Meyer, the thigh and leg rotate on one another in opposite directions,—at the close of extension, and at the commencement of flexion; and that the co-ordinated movements in the patella, the ligaments, and muscles correspond generally with the account given by that observer; but in addition he had ascertained what had previously escaped notice,1. That the articular surfaces of the femur, tibia, and patella are not continuous but faceted surfaces.

A special place in the methods of surgical treatment of bone fractures is occupied by transosseous osteosynthesis using external fixation devices of various designs.Objective: to analyze the lower jaw exoskeleton in finite element programs.Materials and research methods. During the research, 36 human lower jaws were involved from the museum of the Department of Oper-ative Surgery and Topographic Anatomy of the Volgograd State Medical University. They were scanned in 3D. All obtained images were loaded into a virtual scene reconstruction program. Fractures of the lower jaws in the corner area were modeled, an apparatus for external fixation of the lower jaw exoskeleton was installed, and the chewing load on the lower jaw was simulated. The place of application of the force was an area on a small fragment of a repositioned 3D model of the mandibular bone corresponding to the place of attachment of the masseter muscle. The evaluation of virtual studies was carried out according to the results of the stress-strain states of the bones and apparatus, the schedule of displacements of objects and the results of the analysis of the safety factor.Research results and discussion. In the course of evaluating the virtual placement of the mini-fixator wires of the apparatus for external fixation of the lower jaw exoskeleton, it was revealed that the main load is applied to the mini-fixator wires on a large fragment and the bone in the area of the wires. For the possibility of precise positioning of the osteofixers of the external fixation device, a device for the safe installation of the spokes of the lower jaw exoskeleton was also developed.Conclusion. Thus, on the basis of computer mathematical analysis, it can be argued that the developed design of the apparatus for external fixation of the lower jaw exoskeleton works under conditions of the maxillofacial region, performs reposition and fixation of bone fragments of the lower jaw under conditions of chewing functioning of the restored fracture of the lower jaw.
