While a considerable volume of study exists on the biomechanical implications of balloon kyphoplasty, which is used to treat these fractures, the influence of the compacted bone\u2013cement region properties on stress distribution within the vertebral body remains unknown. The following article describes a novel method for modelling this compacted bone\u2013cement region using a geometry-based approach in conjunction with the knowledge of the bone volume fractions for the native and compacted bone regions. Three variables for the compacted region were examined, as follows: (1) compacted thickness, (2) compacted region Young\u2019s modulus and (3) friction coefficient. Results from the model indicate that the properties of the compacted bone\u2013cement region can affect stresses in the cortical bone and cement by up to +28% and \u221240%, respectively. These findings demonstrate the need for further investigation into the effects of the compacted bone\u2013cement interface using computational and experimental methods on multi-segment models.<\/jats:p>","DOI":"10.1177\/0954411913513575","type":"journal-article","created":{"date-parts":[[2013,11,29]],"date-time":"2013-11-29T21:41:20Z","timestamp":1385761280000},"page":"89-97","update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":8,"title":["A parametric finite element analysis of the compacted bone\u2013cement interface following balloon kyphoplasty"],"prefix":"10.1177","volume":"228","author":[{"given":"Philip","family":"Purcell","sequence":"first","affiliation":[{"name":"Bioengineering Technology Centre, Institute of Technology Tallaght, Dublin, Ireland"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Magdalena","family":"Tyndyk","sequence":"additional","affiliation":[{"name":"Medical Engineering Design and Innovation Centre, Cork Institute of Technology, Cork, Ireland"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Fiona","family":"McEvoy","sequence":"additional","affiliation":[{"name":"Bioengineering Technology Centre, Institute of Technology Tallaght, Dublin, Ireland"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Stephen","family":"Tiernan","sequence":"additional","affiliation":[{"name":"Bioengineering Technology Centre, Institute of Technology Tallaght, Dublin, Ireland"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Seamus","family":"Morris","sequence":"additional","affiliation":[{"name":"National Spinal Injuries Unit, Mater Misericordiae University Hospital, Dublin, Ireland"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"179","published-online":{"date-parts":[[2013,11,29]]},"reference":[{"key":"e_1_3_2_2_2","doi-asserted-by":"publisher","DOI":"10.1007\/s00198-006-0172-4"},{"issue":"189","key":"e_1_3_2_3_2","doi-asserted-by":"crossref","first-page":"65","DOI":"10.1097\/00003086-198410000-00008","article-title":"Spinal instability as defined by the three-column spine concept in acute spinal trauma","author":"Denis F","year":"1984","unstructured":"Denis F.
