The aim of the research work is to improve the results of surgical treatment of chronic anterior-medial dislocations of the radial head in children based on the improvement of the method of surgical treatment.
The object of the study was 83 patients with chronic antero-medial dislocations of the head of the radius, treated in the department of the consequences of childhood injuries of the Samarkand branch of the RSSPMC of Traumatology and Orthopedics for the period 2017-2020. The scientific novelty of the research work is the following: it is proved by histological examination that, in case of injuries from up to 1 month ago, the anterior wall of the joint capsule is thin and elastic, which is easily stretched, and from 3 months ago, it thickens, scars and forms fibrous tissue; the possibility of using a fibrous-modified joint capsule for annular ligament plasty in the surgical treatment of chronic antero-medial dislocations of the radial head from 3 months ago was proved; the tactics of surgical treatment of chronic antero-medial dislocations of the head of the radius depending on the deformity of the bones of the forearm were determined; a direct relationship between the results of surgical treatment of chronic antero-medial dislocations of the head of the radius, depending on the duration of the injury, has been proven.
The introduction of research results. Based on the obtained scientific results on the optimization of surgical treatment of chronic antero-medial dislocations of the radial head in children:
based on the results of the development of a method for annular ligament plasty, a patent for an invention was obtained from the Intellectual Property Agency of the Russian Federation “A method for the surgical treatment of chronic anterior medial dislocation of the radial head in children by capsuloplasty according” (patent № 2749870 dated 06/17/2021). The results obtained made it possible to improve the results of surgical treatment, to reduce the period of penetration in the hospital and after the surgical rehabilitation period; based on the results of scientific research on the surgical treatment of chronic anterior medial dislocations of the radial head, the guidelines “Surgical treatment of chronic dislocations of the radial head in children” were approved (Conclusion of the Ministry of Health of the Republic of Uzbekistan 8 n-z / 81 dated February 21, 2022). The results obtained have improved the quality of early diagnosis and treatment of patients with chronic anterior medial dislocations of the radial head in children; based on the results of scientific research on the surgical treatment of chronic antero-medial dislocations of the head of the radius, the methodological recommendations “Conclusion of the Ministry of Health of the Republic of Uzbekistan 8 n-z / 289 of August 31, 2021” were approved. The results obtained have improved the quality of early diagnosis and treatment of patients with chronic anterior medial dislocations of the radial head in children;
Scientific results have been introduced into the practice of healthcare (Conclusion of the Ministry of Health 08-32955 of October 24, 2022), in particular, the Samarkand branch of the Republican Specialized Scientific and Practical Medical Center for Traumatology and Orthopedics, the Bukhara branch of the Republican Scientific Center for Emergency Medical Care, and the Samarkand Regional Children's Multidisciplinary Medical Center. The proposed method for the treatment of chronic anterior-medial dislocations of the radial head in children allowed to reduce the frequency of relapses, increase excellent and good results from 75.6% to 92.9%.

The article provides information, over the past 5 years, on the existing methods of scar tissue correction. Treatment of scar tissue depends on its shape, etiology, predisposition, concomitant somatic diseases. It also provides information on the treatment of soft tissue scars, depending on their location and the patient's phototype.
Subject of the inquiry: the protective carcass of a cabin of universal wheel tractor-cultivator.
Aim of the inquiry: design procedure working out on durability and the substantiation of strength parameters of the carcass of cabin of tractor of a class 1.4.
Methods of inquiry: Researches were spent by methods of mathematical and experimental modeling of deflections of elements of the bearing carcass of the cabin of the tractor at overturning in quasi-static to statement
The results achieved and their novelty:
- the mathematical model of calculation of the carcass of the cabin of the tractor on durability is made;
- the design procedure of the protective carcass of the cabin of the tractor on durability taking into account process of distribution of a zone of plastic deformation on length and height of cross-section section of elements of the construction of the carcass;
- Dependences strength properties of rod elements of the construction of the carcass from the bend and curvature moment.
Practical value: the cabin design procedure on the durability is developed, allowing at a design stage and operational development of a design with high degree of reliability to receive demanded strengthening characteristics (the Patent for the computer program № DGU 01583). The multiple analysis of the construction of the cabin of tractor TTZ 80.20 is carried out and the new carcass of the cabin of the tractor (the Patent for utility model № 1'AP 00563) is offered.
Degree of embed and economic effectiveness: Results of work are transferred to special design engineering bureau “Tractor” for practical use at carrying out of developmental works on modernization and construction development of new carcass of cabins of tractors.
Sphere of usage: automobile construction and tractor construction.
The article presents data on the substantiation of a new design of gaskets for saw gins, characterized by a lightweight type and a composite structure of individual steel elements (disk with splines, rim), welded after preliminary assembly.
The steel structure of the inter-saw gasket, as shown by experimental studies on axial compression, in contrast to aluminum design, is characterized by high strength, less permanent deformation, increased hardness and the ability to maintain performance for a long time under repeated operation without violating the technological conditions of ginning.
Врожденная воронкообразная деформация грудной (ВДГК) клетки у детей наряду с нарушением функционального состояния органов дыхания приводит к существенным изменениям гемодинамики, в результате воздействия на органы средостения.
В настоящее время выявлен устойчивый рост рубцовых повреждений кожи после плановых операций, травм, ожогов, ран. Доля пациентов, обратившихся в лечебные учреждения с рубцовыми дефектами кожи, по данным различных исследований достигает 22-25%. В их структуре ведущее место занимают рубцы со значительно выраженными косметическими дефектами — гипертрофические и келоидные. Для решения проблемы рубцов применяются высокотехнологичные разработки в области медицины. Благодаря этому при лечении рубцов удается достичь лучших результатов.
To date, many methods of surgical treatment of funnel chest deformity have been proposed, but they all have one pronounced and significant drawback - very high trauma. Despite the fact that the first operation for funnel chest deformity was performed more than 100 years ago, the problem of treating this disease cannot be considered completely solved. This is indicated by the fact that more than a hundred methods and modifications of surgical intervention are used to correct the funnel-shaped deformity of the chest in children.
