Placement-induced effects on high tibial osteotomized construct - biomechanical tests and finite-element analyses

BACKGROUND High tibial osteotomy (HTO) with a medially opening wedge has been used to treat osteoarthritic knees. However, the osteotomized tibia becomes a highly unstable structure and necessitates the use of plate and screws to stabilize the medial opening and enhance bone healing. A T-shaped plate (e.g. TomoFix) with locking screws has been extensively used as a stabilizer of the HTO wedge. ...

Extended Finite Element Method for Statics and Vibration Analyses on Cracked Bars and Beams

In this paper, the extended finite element method (XFEM) is employed to investigate the statics and vibration problems of cracked isotropic bars and beams. Three kinds of elements namely the standard, the blended and the enriched elements are utilized to discretize the structure and model cracks. Two techniques referred as the increase of the number of Gauss integration points and the rectangle...

Comparison of Internal Fixations for Distal Clavicular Fractures Based on Loading Tests and Finite Element Analyses

It is difficult to apply strong and stable internal fixation to a fracture of the distal end of the clavicle because it is unstable, the distal clavicle fragment is small, and the fractured region is near the acromioclavicular joint. In this study, to identify a superior internal fixation method for unstable distal clavicular fracture, we compared three types of internal fixation (tension band ...

Eigensolvers and Applications in Finite Element Analyses Eigensolvers and Applications in Finite Element Analyses

SUMMARY This article presents an overview of eigenproblems that arise in current nite-element computations. We focus on a set of applications that have been studied at CERFACS, Centre Europ een de Recherche et de Formation Avanc ee en Calcul Scientiique, and describe the ideas and tools that have been developed to deal with them. The main characteristics of ve diierent cases are given. We also ...
