Scientists from NTU «Kharkiv Polytechnic Institute» presented their latest developments at the international scientific and practical conference «Modern technologies for the treatment and rehabilitation of diseases and combat injuries of the musculoskeletal system.» The forum was held under the auspices of the leading Kharkiv Sytenko Institute of Spine and Joint Pathology National Academy of Medical Sciences of Ukraine. About 100 scientists from Ukraine and Europe joined in the active discussion of new approaches to the treatment of combat injuries. In particular, researchers from NTU «Kharkiv Polytechnic Institute», in collaboration with specialists from the M.I. Sytenko Institute, created and demonstrated high-tech models of lower limb prostheses and technologies for modeling the processes occurring in the «bone-implant» system.
In honor of the 140th anniversary of the birth of the outstanding scientist, founder of domestic orthopedics and traumatology, Mykhailo Ivanovych Sytenko, Sytenko Institute of Spine and Joint Pathology National Academy of Medical Sciences of Ukraine hosted an international scientific and practical conference entitled «Modern Technologies for the Treatment and Rehabilitation of Diseases and Combat Injuries of the Musculoskeletal System.» It brought together more than 100 scientists from Ukraine, the Netherlands, Germany, and Sweden. The purpose of the forum was to unite in order to offer high-tech and affordable solutions for the treatment, diagnosis, and rehabilitation of injuries in military personnel and civilians affected by war. In particular, the event covered topics such as advanced technologies for the treatment of degenerative diseases and the effects of combat injuries to the spine in military personnel, the treatment of joint pathologies and the effects of gunshot wounds to the musculoskeletal system, as well as the rehabilitation of patients with the effects of injuries and diseases of the musculoskeletal system.
The conference was attended by scientists from NTU «Kharkiv Polytechnic Institute», including: Director of the Educational and Scientific Institute of Energy, Electronics and Electromechanics (IEE) Professor Roman Tomashevskyi, Associate Professor of the Department of Industrial and Biomedical Electronics Mykhailo Shyshkin, Director of the Educational and Scientific Institute of Computer Modeling, Applied Physics and Mathematics, Professor Oleksiy Larin, and postgraduate student of the Department of Mathematical Modeling and Intelligent Computing in Engineering Denys Lavinskyi. Scientists from NTU «Kharkiv Polytechnic Institute» and the Professor M.I. Sytenko Institute presented the results of their joint work, which were revealed during the study of various types of loads on a prosthesis-implant system with direct fixation to the bone. The team, represented by Associate Professor of NTU «KhPI» Mykhailo Shyshkin, as well as other authors: O.M. Sytenko, S.E. Bondarenko, O.A. Dynnyk, T.O. Sytenko, O.A. Androsov, presented a report on «Endo-exoprosthesis of the hip with a load-bearing module and means of controlling biomechanical parameters.» The scientists presented a prototype prosthesis with a wireless measuring unit. The next report was presented by Oleksiy Larin, Director of the Educational and Scientific Institute of Computer Modeling, Applied Physics, and Mathematics, and graduate students of the Department of Mathematical Modeling and Intelligent Computing in Engineering, Denys Lavinskyi and Kostyantyn Barbin, together with Oleksandr Sytenko. The presentation on «Intramedullary and extramedullary implants of endo-exoprostheses of the hip: computational analysis of biomechanical differences» revealed the results of modeling loads in the bone-implant system, including load distribution models for different points of force application and friction coefficients.
«The project of creation an intelligent lower limb prosthesis was launched at the request of the Sytenko Institute of Spine and Joint Pathology National Academy of Medical Sciences of Ukraine, which is implementing osseointegration prosthetics—a method in which the prosthesis is connected directly to the bone using an implant,» explains Mykhailo Shyshkin, associate professor at the Department of Industrial and Biomedical Electronics at the National Technical University «Kharkiv Polytechnic Institute.» This solution allows the prosthesis to become almost an extension of the skeleton, reduces pain and rubbing of soft tissues, improves control of the prosthesis, and makes walking more natural. At the same time, this method requires careful rehabilitation, as excessive stress on the implant can lead to complications. That is why it is important for doctors to know exactly what stresses occur during the patient’s movement.» According to the scientist, specialists from the Department of Industrial and Biomedical Electronics at the Kharkiv Polytechnic Institute have created a monitoring system that measures the load on the prosthesis and implant, as well as records transverse forces, speed, and acceleration of movements. This allows for the assessment of gait biomechanics and the regulation of load during postoperative rehabilitation. All data is processed by a microprocessor module and transmitted wirelessly via Bluetooth to the doctor’s smartphone or computer. Thanks to this development, patients can begin rehabilitation earlier, without waiting for the implant to fully integrate with the bone, and doctors can make decisions based on accurate, objective data.
Participants note: «The cooperation between the National Technical University «Kharkiv Polytechnic Institute» and the State Institution «Sytenko Institute of Spine and Joint Pathology National Academy of Medical Sciences of Ukraine» shows that the joint work of polytechnics and doctors can bring a new quality to the treatment and rehabilitation of diseases and combat injuries of the musculoskeletal system.»
Note:
The international scientific and practical conference «Modern technologies for the treatment and rehabilitation of diseases and combat injuries of the musculoskeletal system» was held online and offline in early December under the auspices of the State Institution «Sytenko Institute of Spine and Joint Pathology National Academy of Medical Sciences of Ukraine
Osseointegration prosthetics of the lower extremities is a method in which a metal rod is implanted into the stump bone (e.g., femur or tibia), which fuses with the bone (osseointegration) and is brought out through the skin for direct attachment of the prosthesis without a sleeve.
