Napěťová analýza radiální náhrady vřetenní kosti v loketním kloubu
Hlavoň, Pavel ; Florian, Z.
The paper is focused on computational modeling of elbow articulation with radial head replacement. The main part of the project is aimed towards the creation of computational model of suitable partial endoprothesis of proximal part of the radial bone tissue which would keep the function of the elbow articulation while replacing the distance created by resection. The geometrical and computational model of particular radial head replacement and elbow joint were created and analyzed. Computational model with that implant was compared with given physiological state of elbow articulation. The influence of friction and material characteristics of bone tissue and cartilage on changes in contact pressure (and therefore to the abrasion) were analyzed using this model.

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.

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.
