In this study, the effect of varying cortical and cancellous bone modulus on initial stem micromotion and interface bone strain was examined and the potential consequence of these changes on bone ingrowth and implant migration was reported. A finite element (FE) model of a total hip replacement (THR) was created and the Young's moduli of cortical and cancellous bone were systematically varied to study the relative effect of the quality of both types of bone on the initial stability of a cementless THR. It was found that the initial micromotion and interface bone strain in a THR was significantly affected by the overall stiffness of the femur. In other words, both the reduction of the modulus of cortical and cancellous bone caused an increase in the initial micromotion and interface bone strain. This suggests that for FE studies to be truly predictive, a range of bone quality must be examined to study the performance envelope of a particular stem and to allow comparison with clinical results.<\/jats:p>","DOI":"10.1243\/095441105x34293","type":"journal-article","created":{"date-parts":[[2005,7,18]],"date-time":"2005-07-18T09:42:01Z","timestamp":1121679721000},"page":"265-275","source":"Crossref","is-referenced-by-count":31,"title":["Effect of Bone Material Properties on the Initial Stability of a Cementless Hip Stem: A Finite Element Study"],"prefix":"10.1177","volume":"219","author":[{"given":"A S","family":"Wong","sequence":"first","affiliation":[{"name":"Bioengineering Sciences Research Group, School of Engineering Sciences, University of Southampton, Southampton, UK"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"A M R","family":"New","sequence":"additional","affiliation":[{"name":"Bioengineering Sciences Research Group, School of Engineering Sciences, University of Southampton, Southampton, UK"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"G","family":"Isaacs","sequence":"additional","affiliation":[{"name":"DePuy International Ltd, Leeds, UK"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"M","family":"Taylor","sequence":"additional","affiliation":[{"name":"Bioengineering Sciences Research Group, School of Engineering Sciences, University of Southampton, Southampton, UK"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"179","published-online":{"date-parts":[[2005,4,1]]},"reference":[{"key":"bibr1-095441105X34293","doi-asserted-by":"publisher","DOI":"10.1016\/0021-9290(87)90035-2"},{"key":"bibr2-095441105X34293","doi-asserted-by":"publisher","DOI":"10.1016\/0021-9290(89)90024-9"},{"key":"bibr3-095441105X34293","doi-asserted-by":"crossref","first-page":"187","DOI":"10.1097\/00003086-199202000-00027","volume":"275","author":"Sugiyama H.","year":"1992","journal-title":"Clin.
