TOTAL HIP JOINT REPLACEMENT USING A CUSTOM TRIFLANGE ACETABULAR COMPONENT (LITERATURE REVIEW).

Objective: The aim: The purpose of the article is to analyze the ways of solving the problem of revision hip joint replacement. The article discusses the methods of treatment using a custom triflange acetabular component.

Patients And Methods: Materials and methods: The analysis of 37 literary sources includes a discussion of the features of the use of individual triflange acetabular components and errors in revision hip arthroplasty, which are associated with various factors.

USE OF COMPUTER NAVIGATION IN TOTAL HIP ARTHROPLASTY (LITERATURE REVIEW).

Objective: The aim: Analyze the accuracy and ease of use of various computer navigations in total hip arthroplasty.

Patients And Methods: Materials and methods: Data from about 50 literature sources for the last two decades have been analysed.

Conclusion: Conclusions: Analyzing the accuracy and ease of use of various computer navigations in total hip arthroplasty, we offer two the most promising for further study and improvement systems: a semi-active navigation system and augmented reality system in total hip arthroplasty.

[EXPERIMENTAL STUDY OF THE STRENGTH AND MORPHOLOGICAL CHARACTERISTICS OF THE BONE-FIXATOR SYSTEM WHEN THE IMPLANT SURFACE IS SPRAYED WITH A MATERIAL BASED ON BIOACTIVE GLASS, HYDROXYAPATITE].

The aim of the work is to compare the effect on the strength of bone tissue of spraying ceramic materials on the surface of titanium-nickel plates and pins and to show the results of electron microscopic examination of bone micropreparations at the site of immersion of the implant. Preparations of rat tibia after metal osteosynthesis with intramedullary titanium-nickel pins and titanium-nickel bone plates with spraying on their surface material based on bioactive glass, hydroxyapatite and pins and plates without spraying were investigated. Using a device based on a strain gauge and a caliper with digital display recorded load-deformation diagrams during compression of the test sample, as well as perform bone sampling at the site of immersion of the implant and determine morphological changes in bone using an electron microscope.

[POSSIBILITIES OF THE AUTOLIPOTRANSPLANTS APPLICATION IN REGENERATION OF DEFECTS OF CARTILAGE TISSUES AND ITS PRELAMINATION].

Possibilities of stimulation of the cartilage tissue regenerative properties in damage, using autolipofilling, were studied.The experimental investigations data witnesses efficacy of cartilage restoration while application of the method proposed. The data obtained are forcing for further investigation on possibilities of the cartilage tissue regeneration, using autolipotransplants.

[Estimation of possibilities and methods of operative intervention in complicated tumors of the right colonic flexura].

Experience of surgical treatment of 11 patients, suffering locally-advanced cancer of right colon without remote metastases, was analyzed. In all the patients various variants of extended right-sided hemicolectomy with adjacent organs resection were applied, Surgical tactics in advanced cancer of right colon was substantiated and detailed. The results of investigation conducted witness the trustworthiness of individualized approach application for operative intervention variant choice in patients, suffering locally-advanced complicated cancer of right colon, promoting the results of surgical treatment improvement.
