Material and Methods.To validate the translation of the original version of the ODI, the following process was performed: forward and backward translations, expert committee review of the text, creation of a preliminary version, pre-test of the preliminary version, formation of a final version, study of reliability and validity, and submission of the final version and study results to the author. Results. Adapted Russian version of the ODI is valid. It is recommended to be used in clinical practice and research to measure the level of disability in patients with low back pain.Conclusion. ODI is one of two commonly used instruments recommended by international scientific community for measurement of disability in patients with low back pain. The study was approved by Prof. J. Fairbank, the author of the ODI.

IntroductionPatients with symptomatic single-level combination of degenerative stenosis and low-grade spondylolisthesis are often treated by nerve root decompression and spinal fusion. The gold standard is traditional open decompression and fusion, but minimally invasive method is more and more prevailing. However, there is lack of high-quality studies comparing these two techniques in order to obtain the advantages and certain indications to use one of these methods. The current study includes clinical, safety and radiological endpoints to determine the effectiveness of minimally invasive decompression and fusion (MIS-TLIF) over the traditional open one (O-TLIF).Methods and analysisAll patients aged 40–75 years with neurogenic claudication or bilateral radiculopathy caused by single-level combination of degenerative stenosis and low-grade spondylolisthesis, confirmed by MRI with these symptoms persisting for at least 3 months prior to surgery, are eligible. Patients will be randomised into MIS-TLIF or traditional O-TLIF. The primary outcome measure is Oswestry Disability Index at 3-month follow-up term. The secondary outcomes are patient-reported outcome measures by the number of clinical scales, radiological parameters including sagittal balance parameters, safety endpoints and cost-effectiveness of each method. All patients will be analysed preoperatively, as well as on the 14th day of hospital stay (or on the day of hospital discharge), 3 months, 6 months, 12 months and 24 months postoperatively. The study has the design of a parallel group to demonstrate the non-inferior clinical results of MIS-TLIF compared with the traditional O-TLIF.Ethics and disseminationThe study will be performed according to Helsinki Declaration. The study protocol was approved by the Local Ethical Committee of Priorov National Medical Research Center of Traumatology and Orthopedics in August 2020. Preliminary and final results will be presented in peer-reviewed journals, especially orthopaedic and spine surgery journals, at national and international congresses.Trial registration numberNCT04594980.

Objective. The assessment of reliability of data obtained using a firmware domestic complex Spine Scaner. Material and Methods. Fifty four healthy volunteers have been examined. Criteria for inclusion in the study were the absence of orthopedic pathology, and the Roland-Morris Back Pain Questionnaire and the Oswestry Disability Questionnaire scores being 0. Two independent observers with a different skill level performed the study. Intraobserver and interobserver data repeatability was assessed by the analysis of intraclass correlation coefficient (ICC), standard error of measurement (SEM), and reliability coefficient for each of 31 tested parameters. Results. The observation without fixation of a patient exhibited a low repeatability, with a correlation coefficient being 0.39. Other observation stages showed the acceptable ICC mean values. The best repeatability was achieved in the study performed by the same observer, with the ICC value beiing 0.86. The interobserver repeatability had the lesser values: 0.61 for independent identification of anatomic references and 0.77 for the references identified by one of the observers. Conclusion. The Spine Scaner can be used in clinical practice for defining a shape and spatial orientation of the spine under the following conditions: a reliable fixation of the patient’s trunk, wide experience of the observer, and a strict adherence to the study protocol.

Боль в спине является источником огромного числа случаев нетрудоспособности и одной из самых частых причин обращения к врачам. Хотя в течение жизни боль в спине испытывают множество людей, основные ресурсы системы здравоохранения затрачиваются на помощь небольшому числу (5-10%) пациентов с хроническим болевым синдромом [1, 16].

British Library Cataloguing-in-Publication Data (France) and GSI (Germany). According to this the Symposium had four cochairmen: Profs. Yu.Ts.Oganessian, T.Motobayashi, D.Goutte and G.Muenzenberg. The main goal of the Symposium was to discuss the latest results on the production and study of the properties of the lightest to heaviest nuclei, as well as the plans for fkture joint investigations in the field of exotic nuclei. The results were summarized during a round table discussion.The topics of the Symposium could be conditionally divided into:Methods The big interest in the synthesis of new isotopes of the light elements could explain the numerous reports on this topic. In principle, in the region of neutron-rich isotopes of light elements the nucleon dripline has been reached.Here search is carried out of quasi-stationary states in super neutron-rich systems. Of great interest from this point of view are the super neutron-rich isotopes of hydrogen (4H, 5H, 6H, 7H), helium (9He, "He), as well as the multineutron systems (the tetraneutron). Considerable success in this direction has been achieved at FLNR, JINR. Using 6He and t beams information was obtained on resonance states in 4H and 5H. In a joint FLNR -RIKEN experiment the superheavy isotopes of hydrogen (7H) and helium ('He) were studied. Search for the tetraneutron was carried out in experiments at GANIL. In these experiments the breakup of the neutron-rich *He and I4Be nuclei was used. Twelve events were registered in a neutron detector that could be interpreted as bound states in the system of 4 neutrons. In the d(8He,6Li)4n-reaction, studied at GANIL, a resonance at 2.5 MeV was observed and interpreted as corresponding to the tetraneutron. However, these preliminary results need to be checked with higher statistics. concerns their stability, the magicity of these nuclei was of no importance. New magic numbers N = 6, 16 and 32 were discovered. Moreover, the presence of two shapes -spherical and deformed -was found to exist close to the magic numbers. In that, a significant role belongs to deformation. Many theoretical and experimental studies have been dedicated to these properties. Direct experiments to measure the deformation of nuclei close to the N = 20 shell (32Mg) were carried out. They confirmed the presence of deformation in this nucleus. For the first time a method, based on the nuclear magnetic resonance (NMR), was used. Experiments of precision y-spectroscopy with radioactive ion beams using the detectors EXOGAM, AGATA and EUROGAM were also performed. Nuclear masses in the region of N = 20-28 have also been measured. The results of all these experiments have shown that we are dealing with a new region of nuclei ("island of inversion"). Exotic nuclei manifest their unusual properties also in reactions with other nuclei. Recently new interesting results were obtained in experiments aimed at the measurement of excitation functions of total reaction cross sections, fusionfission and evaporation residue reactions. Such reactions were investigat...
