Abstract

ABSTRACT FINITE ELEMENT ANALYSIS OF A DEVELOPMENTAL HIP DYSPLASIC BONE AND A NORMAL BONE COMPARISON Burcu TANRIVERDİ Master of Science, Department of Bioengineering Advisor: Prof. Dr. Feza KORKUSUZ July 2017, 99 pages DICOM data obtained from scanned computerized tomography(CT) of patients with Developmental Hip Dysplasia (DDH) were modeled as a 3-dimensional hip joint’s pelvis and femur bones in a patient-specific manner appropriate for true anatomy. This modelling has done with one patient and one healthy individual who have different age, sex, and bone mineral density by using two different software; Mimics Materialise and MATLAB. Von- Misses stresses were calculated by using finite element analysis method in ABAQUS Finite Element Analysis(FEA) software under specific loads on bone models. Short stemmed hip prosthesis are modeled in CATIA V5. This prosthesis was embedded to previously modeled femur according to Total Hip Arthroplasty(THA) operation. Finally, the different stress values of the prosthesis is calculated using ABAQUS FEA software. Also, the resolution of DICOM data used before modeling was evaluated and the effect of resolution, zoom, distances between slices and numbers of slices on the obtained model quality was investigated.
