Napěťová analýza radiální náhrady a Souterovy endoprotézy v loketním kloubu
Hlavoň, Pavel ; Kolář, M.
Upon the initiative of the medical team at Traumatological Hospital in Brno, efforts are invested to create possible partial joint replacements of the proximal end of the radius and also proper design of Souter’s endoprothesis in the elbow articulation that would suitably replace the patient’s missing bone tissue and, at the same time, to preserve the same functionality of the radio-humeral connection. This paper speaks about potential geometrical and computational models of a partial joint replacement, Souter’s implant and their stress analysis.

Napjatostní analýza kyčelního kloubu s povrchovou náhradou - simulace chůze
Návrat, Tomáš ; Florian, Z. ; Fuis, Vladimír ; Štekl, M.
In the works dealing with computational hip join modelling, published on this subject in the past, the hip's loading is modelled so as to correspond to standing on one lower limb. At this standing, man remains symmetric at the considered level of resolution, and the force of gravity is identical with the body's axis. We consider the standing because man at walking always stands on one lower limb, and we suppose that, at this standing, in the hip joint there develops a maximum force (we do not suppose rapid walking or shock load). Since the computational models presented up to now consider the standing on one lower limb, it was decided to test computational modelling of even the step' next phase. The problem was formulated as follows: to make a strain-stress analysis of the hip joint with applied surface prosthesis for various phases of the step.

Stress-strain analyze of en elbow joint
Hlavoň, Pavel ; Fuis, Vladimír ; Florian, Z.
Summary: In traumatology demolition of elbow joint there are in many cases, where the surfaces of the joint are damaged. These parts of the joint have been removed during the operation. Function of the joint isn’t away but it nevertheless causes a really strong pain in the patient’s wrist. There is mentioned in the paper stress-strain analyze of the elbow joint in FEM and also geometric model of partial aloplastic for proximal part of radius.
