• 1987 — defended his Candidate of Sciences dissertation on the prevention and treatment of chronic ankle injuries;
• Since 1987 — began researching the scientific aspects of shoulder girdle pathology;
• 1991-1992 — worked as an assistant in the Department of Traumatology, Orthopedics, and Field Surgery at Kharkiv Medical Institute, while also treating patients in the trauma departments of the 4th Emergency Hospital;
• 1992-1994 — worked under contract as an orthopedic traumatologist at the central hospital of Hodeidah Province, Yemen Arab Republic;
• Since 1994 — research fellow at the Biomechanics Laboratory of the Kharkiv Research Institute of Orthopedics and Traumatology named after Prof. M.I. Sytenko;
• 1996 — for the work «Le mecanisme de la reduction de la torsion est un nouveau mecanisme de la stabilisation de l’articulation scapulo» received the first scientific award in Ukraine’s history from the International Society of Orthopaedic Surgery and Traumatology, the SICOT-SIROT Award;
• 2000 — awarded the title of senior research fellow;
• 2001 — defended his Doctor of Sciences dissertation on shoulder joint instability;

Since 2001, he has been developing and implementing a new osteosynthesis method using artificial carbon composite implants to treat bone fractures in the setting of osteoporosis. He later participated in developing new, original carbon-material implants and methods for their use in spinal surgery and joint replacements. Carbon implants were subsequently used to replace bone defects after tumor removal and in cases of traumatic bone defects. More than 150 osteosynthesis procedures, over 80 bone-defect replacement operations, and several dozen other operations using carbon implants have been performed. This work resulted in 8 Ukrainian patents for inventions, more than 30 scientific papers, and over 20 presentations at scientific forums of various levels, including international ones.

A.A. Tiazhelov’s priority area of research is shoulder girdle pathology. The laboratory’s main areas of research are modeling normal and pathological joint function in the upper and lower limbs; studying the mechanogenesis of limb deformities; biomechanical analysis of corrective and reconstructive surgery; modeling osteosynthesis methods and bone-defect replacement; analyzing classification systems; and conceptual modeling of pathological conditions and processes.

He combines scientific and clinical work with teaching. For his active participation in research, Oleksii Alimovych was awarded the title of honorary professor of the Donetsk National Medical University Research Institute of Traumatology and Orthopedics, and he also received a Certificate of Merit from the Department of Health of the Donetsk Regional State Administration. He has repeatedly received certificates of merit from the Verkhovna Rada, the National Academy of Medical Sciences, and the Ministry of Health of Ukraine.
