    Background. Currently, limb lengthening is a widespread operation used in clinical and cosmetic practice. However, in the process of implementing this technology, its main drawbacks were revealed: the duration of treatment and the slowing down of the process of osteogenesis in the elongation zone. Rapid distraction in the external fixator or with an intramedullary rod can lead to a slowdown in osteogenesis and soft tissue complications, including neuropathy and soft tissue eruption.The aim β€” to develop a present its own concept of stimulating distraction osteogenesis in limb elongation, based on many years of clinical experience.Materials and Methods. This study is based on the long-term experience of the Ilizarov Center in limb lengthening (using data from clinical and experimental studies performed in the institution: more than 200 animals and 8000 patients), as well as literature data.Results. The introduction of the considered methods of stimulation of osteogenesis made it possible to significantly reduce the treatment time of patients and thereby reduce the number of possible complications characteristic of transosseous osteosynthesis. Systemic diseases, congenital malformation of the segment can negatively affect the quality of the new bone.Conclusions. The use of methods of stimulation of osteogenesis allows to reduce treatment time and increase osteogenesis when limb lengthening, which allows, if necessary, to provide re-lengthening of the segment without increasing treatment time.ΠΠΊΡ‚ΡƒΠ°Π»ΡŒΠ½ΠΎΡΡ‚ΡŒ.

    Purpose : the comparative study of the immunity features of elite athletes of different sports. Material : study involved athletes of the highest mastery level of cyclic and acyclic sports (n = 147, age 18-23 years). Athletes were divided into groups by kinds of sport. Skiers (n = 54), swimmers (n = 23), wrestlers (n = 49), boxers (n = 21). Results : It was determined that athletes of acyclic sports (wrestlers and boxers) had a significant double increase in the level of secretory immunoglobulin IgA. In parallel, the level of immunoglobulins IgG is reduced. The highest indicators of lysosomal activity were recorded in skiers. Boxers, wrestlers, and swimmers had a decrease in the lysosomal activity level. The maximum phagocytic number is determined in wrestlers, and the minimum - in boxers. Conclusions : Comparative study of the immunity features of elite athletes in various sports suggests that there is a strain on the immune status. This condition is especially expressed in acyclic sports athletes (wrestling, boxing). This is due to the loads in the preparation process. The data received allow to confirm the significance of immune protection indicators in monitoring the athletes functional status

    Changes of intramedullary tissue fluid pressure in the shaft cavity of tibia have been studied in experiment after hypertension modeling and tunneling. There have been compared this changes pain index in the knee joint after femoral and tibial metaphyses tunneling. It has been revealed that tunneling leads to reduction of hypertension in bone methaphyses and to pain decrease in the knee joint.Π’ экспСримСнтС ΠΈΠ·ΡƒΡ‡Π°Π»ΠΈ измСнСния интрамСдуллярного давлСния Ρ‚ΠΊΠ°Π½Π΅Π²ΠΎΠΉ Тидкости Π² полости Π΄ΠΈΠ°Ρ„ΠΈΠ·Π° Π±ΠΎΠ»ΡŒΡˆΠ΅Π±Π΅Ρ€Ρ†ΠΎΠ²ΠΎΠΉ кости послС модСлирования Π³ΠΈΠΏΠ΅Ρ€Ρ‚Π΅Π½Π·ΠΈΠΈ ΠΈ примСнСния Ρ‚ΡƒΠ½Π½Π΅Π»ΠΈΠ·Π°Ρ†ΠΈΠΈ.

The study aims to investigate digital literacy and digital didactics as the basis for the development of new learning models via comparative qualitative research methods. As a result, the principle of personalization implies the ability of a student to independently determine the purpose of training, choose a strategy for the educational process, the pace and level of development of the educational program. In conclusion, to determine digital literacy, an index was developed which shows how prepared the teacher is for learning online and through innovation
