Aim ― Modern dentistry cannot exist without dental implantation. The lifetime of the installed implants depends on condition bone and quality treatment planning surgery technique. Usually, complications during implant are related to inability accurately predict location intraosseous structure that entails selection wrong type installation position. Methods This work is devoted "bone-implant" system investigation aiming optimization prostheses installation. objective this study was develop...
Object of study: A study the biomechanical characteristics human heart ventricles was performed. 80 hearts were extracted during autopsy corpses adults (40 women and 40 men) aged 31-70 years. The samples investigated in compliance with recommendations ethics committee. Methods: Tension compression tests performed help uniaxial testing machine Instron 5944. Cardiometry also Results: In this work, techniques for ventricle wall properties estimation developed. Regularities age gender...
Object of study: The research is aimed at development personalized medical treatment. Algorithm was developed for patient-specific surgical interventions the cardiovascular system pathologies. Methods: Geometrical models biological objects and initial boundary conditions were realized by diagnostic data specific patient. Mechanical histomorphological parameters obtained with help mechanical experiments on universal testing machine. Computer modeling studied processes conducted finite element...
This article reviews studies of Fixion expandable nail biomechanical properties in case long bones fractures osteosynthesis. The purpose this study was to systematize researches dedicated the nail. There were found seven published between 2005 and 2008. Among them, six are devoted mechanical experiments, one is a comment study. In four papers, authors compared locked nails. Expandable proved be highly effective device for fixation bone fractures. However, mid-shaft significantly less stable...
The purpose of the study was to assess reliability, accuracy and effectiveness a mobile application SpinoMeter for measuring sagittal balance spino-pelvic complex in comparison with desktop preoperative planning system Surgimap. Methods developed 2019 at laboratory Medical Decision Support Systems Saratov State University. is intended actual calculating optimal parameters particular patient. Pelvic incidence (PI), lumbar lordosis (LL), sacral slope (SS) pelvic tilt (PT) were measured help...
The main goal of preoperative planning for patients with pathologies the musculoskeletal system is to obtain high-quality anatomical and functional results. solution this problem could be achieved through selection appropriate implants technique their installation, which ensure stability structure reposition bone fragments, as well by recreating optimal biomechanics operated segment. All over world, modern digital technologies are widely introduced into clinical practice. In traumatology,...
3D geometric solid computer model of spinal-pelvic complex was constructed on the basis computed tomography and full body X-ray in standing position data. The used for biomechanical analysis compensatory mechanisms arising spine with anteversion retroversion pelvis. results numerical modeling are good agreement clinical
Objective. To assess the results of clinical approbation individual finite-element biomechanical model a patient’s spino-pelvic complex with subsequent modeling best option surgical treatment. Material and Methods. A changes in sagittal profile patient degenerative disease lumbosacral spine, bilateral spondylolysis, unstable grade 2 spondylolisthesis L4 vertebra was performed. The developed made it possible to characteristics stress-strain state spinal motion segments aroused due development...
Prolonged hip arthritis in juvenile (JA) is a cause of serious joint destruction, leading to severe pain and functional disorders. Objective: assess the results total arthroplasty (THA) patients with JA. Subjects methods. The investigation enrolled 20 women 2 men. Their mean age at time surgery was 27.9 (18–49) years, weight – 47.7±2 kg. Mean height 155.1 cm, which confirms growth retardation these patients. disease duration averaged 7.1 years. Mild protrusion acetabulum stated 9 (41%)...
An individual approach to modeling the hemodynamics of carotid arteries and Willis circle is required in cases where there a question need for surgical treatment due an atherosclerotic lesion or occurrence aneurysms. The development rigorous problem statement, including boundary conditions, vessel properties personalized geometry, urgent scientific that this work devoted to. In study, data numerical artery were compared with obtained using ultrasound. Geometric model bifurcation was built...
