Cervical Disc Arthroplasty versus Disc Fusion: A Finite Element Study
INTRODUCTION: Disc degeneration is a natural process and is widely prevalent. The level of disc degeneration and the type of treatment varies from person to person. Fusion is a commonly chosen treatment option. However clinical and biomechanical studies have shown that spinal levels adjacent to a fusion experience increased motion and higher stress which may lead to adjacent-segment disease [1]...
متن کاملA Comparison Study on Various Finite Element Models of Riveted Lap Joint by the Use of Dynamic Model Updating
Till now, various models have been proposed in literature to simulate the behavior of riveted structures. In order to find the most accurate analytical method in modeling the dynamic behavior of riveted structures, a comparison study is performed on several of these models, in this research. For this purpose, experimental modal analysis tests are conducted on a riveted plate to verify the effic...
متن کاملSecond Molar Uprighting with Temporary Anchorage Devices: A Finite Element Study
BACKGROUND AND OBJECTIVE: Premature loss of mandibular first molar is a common problem in adults. Mesial tipping of second molar may occur in this situation. Various orthodontic mechanics have been proposed for molar uprighting. The aim of this study was to compare four methods of molar uprighting using Finite Element Analysis(FEM). METHODS: In first model of this finite element study, a 0.019...
متن کاملFinite Element Galerkin Models and Identified Finite Element Models - a Comparative Study
A new approach to derive a finite element discretisation of PDE equations soley from observations is compared, in terms of approximation accuracy, with the standard finite element Galerkin approach which assumes knowledge of the governing PDE’s. It is shown both in theory and by means of an example that, for a given model order, the identified model is more accurate than the equivalent finite e...
متن کاملCervical arthroplasty in two dogs with disk-associated cervical spondylomyelopathy.
CASE DESCRIPTION A 4-year-old sexually intact male Doberman Pinscher (dog 1) was evaluated for signs of recurrent cervical pain and ataxia, and a 12-year-old neutered male mixed-breed dog (dog 2) was evaluated for a 4-month history of ataxia and tetraparesis. CLINICAL FINDINGS Examination via magnetic resonance imaging (MRI) revealed spinal cord compression due to disk-associated cervical spo...
