Computational model of Swanson's PIP joint implant
Kult, Jaroslav ; Jíra, Josef
The Swanson's proximal interphalangeal joint (PIP) soft skeletal implant was introduced already in the 60's of the 20th century by Dr. Alfred B. Swanson. Its modifications are nowadays produced around the world.
Analysis of Finger Flexion Contractures Treatment
Kult, Jaroslav ; Jírová, Jitka
The flexion contractures of finger tendons are a serioustherapeutic problem in orthopedics and reconstructive surgeryof the hand. They cause limitation of the range of finger motionand thus difficulties in patient's daily life.
Using Ansys FEM System for Solution of Nonlinear Problemsin Biomechanics
Jiroušek, Ondřej ; Jíra, J. ; Jírová, Jitka ; Kult, J.
The contribution reports on problems solved by a Laboratoryof Biomechanics team using numerical FEM system Ansys.The first problem is a complex analysis of Swansons,sprosthesis of interphalangeal joint and its interactionwith phalangeal and metacarpal bone.
Experimental Methods Used for Verification of theComputational Model of Silicon Rubber Implant
Kult, J. ; Vavřík, Daniel
The contribution from the field of biomechanics reportson a complex analysis of Swanson's prosthesis ofinterphalangeal joint and its interaction with phalangealand metacarpal bone.
Interaction of Bone an Swanson,s Finger Joint Implant
Kult, Jaroslav
Mechanical analysis of Swanson,s IP joint prosthesis and its interaction with bone based on 3D FE model. The FE model was verified by photoelastic measurement. The checked load cases come out of experiences of surgeons. Both the models show good correspondence and the stresses in the implant are low.
Tvorba matematických modelů pro metodu konečných prvků na základě dat získaných z počítačové tomografie
Jiroušek, Ondřej ; Jírová, Jitka
Tvorba matematických modelů pro numerickou analýzu pomocí metody konečných prvků na základě dat získaných z počítačové tomografie. Z CT-snímků vytvořen prostorový model a převeden do systému ANSYS pomocí standartních příkazů preprocesorů PREP7. Problém uvažován jako prostorový kontaktní problém s uvažováním geometrické i fyzikální nelinearity.
Construction of Mathematical Models for the Finite Element Analysis on Basis of Data Obtained from Computer Tomography
Jiroušek, Ondřej
Algorithms for the construction of mathematical model for the finite element method using the computer tomography scans are shortly described in this paper.The stress analysis of a new type implant used in finger reconstruction surgery was carried out with the help of a model constructed using this algorithm.
Modelling of Interphalangeal Joint Prosthesis
Kult, Jaroslav
Complex mechanical analysis of Swansons prosthesis of interhalangeal joint. All common load cases (according to experiences of orthopaedists) were considered: 10 degrees, flexion up to 75 degrees and transverse motion in the frontal plane 10 degrees. The finite element model was verified by the photoelastic measuring.
Biomechanical Analysis of an Implant Used in Finger Reconstruction Surgery on the Basis of Data Obtained from Computer Tomography
Jiroušek, Ondřej
Comparative study of two algorithms for construction of a mathematical model for the finite element method based on the computer tomography data. Two different algorithms have been developed and compared in an example of a three-dimensional model for stress ana lysis of a new type of an implantant used in finger reconstruction surgery.
