Design process of cementless femoral stem using a nonlinear three dimensional finite element analysis

Background: Minimal available information concer ning hip morphology is the motivation for several researchers to study the difference between Asian and Western populations. Current use of a universal hip stem of variable size is not the best option for all femur types. This present study proposed...

Current use of a universal hip stem of variable size is not the best option for all femur types. This present study proposed a new design process of the cementless femoral stem using a three dimensional model which provided more information and accurate analysis compared to conventional methods. Methods: This complete design cycle began with morphological an alysis, followed by femoral stem design, fit and fill analysis, and nonlinear finite element analysis (FEA). Various femur parameters for periosteal and endosteal canal diameters are measured from the osteotomy level to 150 mm below to determine the isthmus position. Results: The results showed better total fit (53.7%) and fill (76.7% ) canal, with more load distributed proximally to prevent stress shielding at calcar region. The stem demonstrated lower displacement and micromotion (less than 40 μ m) promoting osseointegration between the stem–bone and providing primary fixation stability. Conclusion: This new design process could be used as a preclinical assessment tool and will shorten the design cycle by identifying the major steps which must be taken while designing the femoral stem BioMed Central 2014 Article PeerReviewed application/pdf en http://irep.iium.edu.my/38204/1/Design_process_of_cementless_femoral_stem_using_a.pdf application/pdf en http://irep.iium.edu.my/38204/4/38204_Design%20process%20of%20cementless_SCOPUS.pdf Baharuddin, Mohd Yusof and Salleh, Sh-Hussain and Zulkifly, Ahmad Hafiz and Lee, Muhammad Hisyam and Mohd Noor, Alias and A Harris, Arief Ruhullah and Abdul Majid, Norazman and Abd Kader, Ab Saman (2014) Design process of cementless femoral stem using a nonlinear three dimensional finite element analysis.
