The study was conducted on 22 healthy men aged 18-23 years. The primary motor cortex innervating the lower limb was stimulated with transcranial magnetic stimulation. Using transcutaneous electrical stimulation of the spinal cord, evoked motor responses of the muscles of the lower extremities were initiated when electrodes were applied cutaneous between the spinous processes in the Th11-Th12 projection. Research protocol: Determination of the thresholds of BMO of the muscles of the lower extremities during TESCS; determination of the BMO threshold of the TA muscle in TMS; determination of the thresholds of the BMO of the muscles of the lower extremities during TESCS against the background of 80% and 90% TMS. It was found that magnetic stimulation of the motor cortex of the brain leads to an increase in the excitability of the neural structures of the lumbar thickening of the spinal cord and an improvement in neuromuscular interactions. Key words: transcranial magnetic stimulation, transcutaneous electrical stimulation of the spinal cord, neural networks, excitability, neuromuscular interactions.

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.

Background and objectives: In this study, the accuracy of point-of-care ultrasonography (POCUS) was compared to radiography (XR) in the diagnosis of fractures, the determination of characteristics of the fractures, and treatment selection of fractures in patients admitted to the emergency department (ED) due to trauma and suspected long bone (LB) fractures. Materials and Methods: The patients were included in the study, who were admitted to ED due to trauma, and had physical examination findings suggesting the presence of fractures in LB (humerus, radius, ulna, femur, tibia, and fibula). The patients were evaluated by two emergency physicians (EP) in ED. The first EP examined LBs with POCUS and the second EP examined them with XR. LBs were evaluated on the anterior, posterior, medial, and lateral surfaces and from the proximal joint to the distal one (shoulder, elbow, wrist, hip, knee, and ankle joint) in both longitudinal and transverse axes with POCUS. Results: A total of 205 patients with suspected LB fractures were included in the study. LB fractures were determined in 99 patients with XR and in 105 patients with POCUS. The sensitivity, specificity, positive predictive value, negative predictive value of POCUS in determining the fractures were 99%, 93%, 93%, and 99%, respectively, compared to XR. Compared to XR, POCUS was able to determine 100% of fissure type fractures (kappa (κ) value: 0.765), 83% of linear fractures (κ: 0.848), 92% of fragmented fractures(κ: 0.756), 67% of spiral fractures (κ:0.798), 75% of avulsion type fractures (κ: 0.855), and 100% of full separation type fractures (κ: 0.855).Conclusions: This study has demonstrated that POCUS has a high sensitivity in diagnosing LB fractures. POCUS has a high sensitivity in identifying fracture characteristics. POCUS can be used as an alternative imaging method to XR in the diagnosis of LB fractures and in the determination of fracture characteristics.

The study of human gait is of interest in determining its individual characteristics that affect the loads experienced by the joints of the lower extremities. To analyze the gait in the lateral projection, an experiment was carried out with placed markers on the subject's body to determine the interarticular angles in the hip, knee and ankle joints. The graphs of the dependences of these angles on time were built, corresponding to a certain phase of the step. It was found that the range of changes in the angle in the left ankle joint in the subject was significantly different from the dependence obtained for the right joint. Based on the subject's anamnesis, we associate these differences with the fact that there was an ankle joint injury that affected the condition of the ligamentous apparatus of the joint. In further work, it is proposed to consider a person's gait not only in the lateral, but also in the frontal (anteroposterior) plane to assess all movements in the joints, especially those associated with the abduction of the limbs and the human body from the vertical line on the specified plane.

Wire Tension

The work shows correct procedures needed in order to gather reliable data from measurement of displacements versus axial load in a laboratory mounting of the Ilizarov external fixator. The mechanism of settling after load cycling is investigated. Detension under load is a major problem of wires. By means of vibration frequency measurements, tests on single wire allow determination of reduction in wire tension due to transverse loading: it is found that, almost independently from the amount of clamp tightening, the tension reaches a lower limit related only to the transverse load and not related to pretension. It is shown that, for higher clamp tightening torques, wire detension must be attributed to permanent plastic deformation of the wires; moreover, it is shown that the unavoidable errors in the spacing of the tensioned wires lead to marked decrease of their stiffness under transverse load.
