Several design features were introduced to provide the much needed stability for bone integration. These include fins, fiber mesh, beads, indentations and collars. The use of collar has been a subject of controversy with mixed reports of clinical outcomes. In this study, the effectiveness of collar in terms of providing stability was analysed using finite element method. Three dimensional model of a human femur was constructed from CT dataset and hip arthroplasty was simulated. With an applied joint contact load simulating physiological gait, micromotion of the implant relative to the bone was calculated via an experimentally validated algorithm. Results showed that collar did not improve stability of the whole stem but only around the medial calcar region. 2011-01-10T04:05:31Z 2011-01-10T04:05:31Z 2010-08-01 Working Paper Vol. 31, p. 605-607 978-3-5407-9038-9 1680-0737 http://www.springerlink.com/content/v82mqw0v36060461/fulltext.pdf http://hdl.handle.net/123456789/10451 en Proceedings of the International Federation for Medical and Biological Engineering (IFMBE) 2010 International Federation for Medical and Biological Engineering
