However, due to the lack of direct measurement of in vivo performance of the PFF fixation construct, it is unknown whether current standard mechanical tests or previous experimental and computational studies have appropriately reproduced the in vivo mechanics of the plate. To provide a basis for the evaluation and development of appropriate mechanical tests for assessment of plate fracture risk, this study applied loads of common activities of daily living (ADLs) to implanted femur finite element (FE) models with PFF fixation constructs with an existing or a healed PFF. Based on FE simulated plate mechanics, the standard four-point-bend test adequately matched the stress state and the resultant bending moment in the plate as compared with femur models with an existing PFF. In addition, the newly developed constrained three-point-bend tests were able to reproduce plate stresses in models with a healed PFF. Furthermore, a combined bending and compression cadaveric test was appropriate for risk assessment including both plate fracture and screw loosening after the complete healing of PFF. The result of this study provides the means for combined experimental and computational preclinical evaluation of PFF fixation constructs.<\/jats:p>","DOI":"10.1115\/1.4052372","type":"journal-article","created":{"date-parts":[[2021,9,10]],"date-time":"2021-09-10T07:04:33Z","timestamp":1631257473000},"update-policy":"https:\/\/doi.org\/10.1115\/crossmarkpolicy-asme","source":"Crossref","is-referenced-by-count":2,"title":["Simplified Mechanical Tests Can Simulate Physiological Mechanics of a Fixation Construct for Periprosthetic Femoral Fractures"],"prefix":"10.1115","volume":"144","author":[{"given":"Xiang","family":"Chen","sequence":"first","affiliation":[{"name":"Center for Orthopaedic Biomechanics, University of Denver, Denver, CO 80208"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Casey A.","family":"Myers","sequence":"additional","affiliation":[{"name":"Center for Orthopaedic Biomechanics, University of Denver, Denver, CO 80208"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Chadd W.","family":"Clary","sequence":"additional","affiliation":[{"name":"Center for Orthopaedic Biomechanics, University of Denver, Denver, CO 80208"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Ryan J.","family":"DeWall","sequence":"additional","affiliation":[{"name":"DePuy Synthes, West Chester, PA 19380"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Bryan","family":"Fritz","sequence":"additional","affiliation":[{"name":"DePuy Synthes, West Chester, PA 19380"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Michael","family":"Blauth","sequence":"additional","affiliation":[{"name":"DePuy Synthes, West Chester, PA 19380"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Paul J.","family":"Rullkoetter","sequence":"additional","affiliation":[{"name":"Center for Orthopaedic Biomechanics, University of Denver, Denver, CO 80208; Department of Engineering & Computer Science, 2155 East Wesley Avenue, Denver, CO 80208"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"33","published-online":{"date-parts":[[2021,10,11]]},"reference":[{"issue":"3","key":"2021101106534274800_bib1","doi-asserted-by":"crossref","first-page":"107","DOI":"10.1177\/2151458512462870","article-title":"A Review of Periprosthetic Femoral Fractures Associated With Total Hip Arthroplasty","volume":"3","year":"2012","journal-title":"Geriatr.
