STRAIN-STRESS ANALYSIS OF PHYSIOLOGICAL AND PATHOLOGICAL HIP JOINT OF ADULT HUMAN USING FEM

conference paper

en

At present the hip joint belongs to the most frequently solved segments of the human body. This paper deals with biomechanical problems of physiologically and pathologically developed hip joints of adult human. Numerous disorders of the hip joint are characterized by various deformities of the femoral head and acetabulum, which are a frequent cause of unfavourable mechanical conditions and decrease of moveability in the joint accompanied by pain. A lot of deformities of the hip joint can be treated with a suitable surgical interventions based on the improvement of improper mechanical conditions in the hip joint that result from modification and reconstruction of its geometry. For modelling of particular types of the surgical interventions on pathological hip joints (osteotomies, acetabuloplasty), it is necessary to analyse the behaviour of physiological and pathological hip joint. These problems have currently been a common subject of investigations carried out by the Institute of Solid Mechanics, Mechatronics and Biomechanics, FME BUT and First Orthopaedic Department, St. Anne's University Hospital in Brno. The aim of the work was to create and to analyse the computational models of the physiological and pathological hip joint using computational modelling based on the Finite Element Method (FEM) and ANSYS software system, and finally to compare the results from computational modelling with the results obtained from clinical practice.
