ANATOMICAL AND BIOMECHANICAL ROLE OF STATIC STABILIZERS OF THE ACROMIOCLAVICULAR JOINT.

Objective: The aim: To determine the anatomical and biomechanical significance of the static stabilizers of the acromioclavicular joint by conducting numerical modeling using the finite element method and experimental investigation.

Patients And Methods: Materials and methods: To ensure the study, modeling of the deformation processes of the clavicle and scapula systems with various combinations of ligament damage was conducted. The COMPAS-3D software package was used to build the simulation model, which allowed obtaining models that are closest to reality.

Management of severe defects of humerus in combat patients injured in Russo-Ukrainian war.

Introduction: Russo-Ukrainian war is associated with application of high-energy weapon, causing severe multifragmental injuries to the bones an associating with severe bone defects. The aim of the study was to evaluate various methods to treat combat patients with severe defects of humerus and to demonstrate the experience of orthopedic war surgeons in managing gunshot injuries to the humerus defects in the ongoing war.

Patients And Methods: A 24 patients were active-duty military personnel of Armed Forces of Ukraine.

BIOMECHANICAL STUDY OF MINIMALLY INVASIVE TECHNIQUES IN SURGICAL TREATMENT OF THE TIBIA PROXIMAL EPIMETAPHYSIS FRACTURES.

Objective: The aim: Improving efficiency of the tibia proximal epimetaphysis fractures treatment by introducing minimally invasive techniques using the up-to-date metallic constructions.

Patients And Methods: Materials and methods: The study is based on the results of examination and treatment of 119 patients, using arthroscopic technique. The results were evaluated regarding the P.

MAGNETIC RESONANCE IMAGING DETERMINATION OF STRUCTURAL DISORDERS OF ARTICULAR CARTILAGE: MODERN DIAGNOSTIC TECHNOLOGIES AND RESEARCH PROSPECTS.

Objective: The aim: Tо present enhanced (with the contrast) and non-enhanced MRI techniques, provide an update on the physical principles of the main and latest techniques, and describe the advantages and disadvantages of each technique. The information obtained can provide an opportunity to diagnose changes at the structural level of the articular cartilage, thereby improving the early diagnosis of OA and optimizing the tactics of further treatment of patients.

Patients And Methods: Materials and methods: We retrospectively reviewed publications published in the PubMed and Embase databases up to February 2023 using the following terms: "MRI cartilage", "MRI osteochondral lesion", "T2 mapping cartilage", "dGEMRIC", "DWI cartilage", "DTI cartilage", "sodium MRI cartilage", "gagCEST", "T1rho cartilage".

DOES THE APPLICATION OF CONVERSION FRACTURE-TREATMENT METHOD AND THE TECHNOLOGY OF TELEMEDICAL MOVEMENT MONITORING AFFECT THE LONG-TERM RESULTS OF THE TREATMENT OF VICTIMS WITH MULTIPLE GUNSHOT LONG BONES FRACTURES?

Objective: The aim: To improve the results of treatment of patients with multiple gunshot fractures of long bones by developing the technology of fixation method conversion with combined autoplasty and postoperative telemedical control (loading +ROM (range of motion).

Patients And Methods: Materials and methods: Two comparison groups were formed: the main (84 patients) and the control (62 patients). For the patients of this group all elements of the restorative treatment system were used (DCO, extrafocal osteosynthesis (including hinged), ultrasonic cavitation, NPWT, biochemical indicators of blood, conversion technology with usage of regenerative technologies, rehabilitation program) and telemedical control with applications (ROM+weight bearing).
