Abstract
The aim of the studywas to assess capability and benefits of this method, its technical feasibility and safety regarding a damage of the most essential anatomical structures.Material and methods.The study involved 15 natural humeral bones; their parameters - the length and shape of the plates – were measured for osteosynthesis. Bone osteosynthesis was further performed on 14 intact upper limbs taken from 7 non-fixed corpses of people died at the age of 63–77 using the discussed method; after that, the operated limbs were studied using preparating technique. Furthermore, after plate application on two shoulder sections, 12 transverse cuts with their epoxy plastination were made at three levels according to the original technology; this was followed by the preparation of histotopographic sections.Results.The results obtained have demonstrated that for the new method of bone osteosynthesis it is advisable to use metal plates 220–260 mm long with spiral twisting clockwise for the right humerus and counterclockwise for the left. Average distances from the fixed plate to the humerus, tendon of the long head of the biceps of the shoulder muscle, large blood vessels and peripheral nerves were determined using precision preparation and measurements; the measurements were also performed on transparent plate-shaped shoulder cuts. All the above validates safety of the discussed method regarding a damage of the most essential anatomical structures and allow to successfully use it in the clinical practice.Conclusion.The discussed technique of plastinated transverse shoulder cuts with further experimental fixation of metal implants for osteosynthesis ensures safety of the initial topographic and anatomical relationships of these structures with anatomical structures. In addition, high transparency of the tissues created by epoxy plastination allows determining distances between implants and important anatomical structures with high precision, the fact being of great significance in applied anatomical studies.

Summary
Целью данной работы явилась оценка возможности и преимуществ практического использования технологии изготовления пластинированных распилов анатомического материала для обоснования с топографо-анатомических позиций нового способа малоинвазивного накостного остеосинтеза плечевой кости с учетом его технической выполнимости и безопасности в отношении повреждения важных анатомических структур. Посредством прецизионного препарирования и измерений, а также на прозрачных пластинированных распилах плеча определены средние расстояния от установленной пластины до плечевой кости, сухожилия длинной головки двуглавой мышцы плеча, а также до крупных кровеносных сосудов и периферических нервов, что подтвердило безопасность предложенного способа в плане риска повреждения важных анатомических структур и позволило успешно использовать его в клинике. Предложенный способ изготовления поперечных пластинированных распилов конечностей после экспериментальной установки металлических имплантов для остеосинтеза обеспечивает сохранность исходных топографо-анатомических взаимоотношений таких конструкций с анатомическими структурами. The aim of the study was to assess capability and benefits of this method, its technical feasibility and safety regarding a damage of the most essential anatomical structures
