Although several fixation procedures have been developed with high fixation stability and union rates, long-term weight-bearing constructs are still lacking. Therefore, the aim of the present study was to evaluate the stability of a double-plate procedure using reversed contralateral locking compression-distal femoral plates for fixation of Vancouver B1 periprosthetic femoral fractures under full weight-bearing.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods<\/jats:title>\n                    <jats:p>Single- and double-plate fixation procedures for locking compression-distal femoral plates were analysed under an axial load of 1,500\u00a0N by finite element analysis and biomechanical loading tests. A vertical loading test was performed to the prosthetic head, and the displacements and strains were calculated based on load-displacement and load-strain curves generated by the static compression tests.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>\n                      The finite element analysis revealed that double-plate fixation significantly reduced stress concentration at the lateral plate place on the fracture site. Under full weight-bearing, the maximum von Mises stress in the lateral plate was 268\u00a0MPa. On the other hand, the maximum stress in the single-plating method occurred at the defect level of the femur with a maximum stress value of 1,303\u00a0MPa. The principal strains of single- and double-plate fixation were 0.63\u2009% and 0.058\u2009%, respectively. Consistently, in the axial loading test, the strain values at a 1,500\u00a0N loading of the single- and double-plate fixation methods were 1,274.60 \u00b1 11.53 and 317.33 \u00b1 8.03 (\u00d7 10\n                      <jats:sup>\u2212\u20096<\/jats:sup>\n                      ), respectively.\n                    <\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusions<\/jats:title>\n                    <jats:p>The present study suggests that dual-plate fixation with reversed locking compression-distal femoral plates may be an excellent treatment procedure for patients with Vancouver B1 fractures, allowing for full weight-bearing in the early postoperative period.<\/jats:p>\n                  <\/jats:sec>","DOI":"10.1186\/s12891-021-04152-5","type":"journal-article","created":{"date-parts":[[2021,3,13]],"date-time":"2021-03-13T10:02:46Z","timestamp":1615629766000},"update-policy":"https:\/\/doi.org\/10.1007\/springer_crossmark_policy","source":"Crossref","is-referenced-by-count":13,"title":["Finite element analysis of double\u2010plate fixation using reversed locking compression\u2010distal femoral plates for Vancouver B1 periprosthetic femoral fractures"],"prefix":"10.1186","volume":"22","author":[{"given":"Daisuke","family":"Takahashi","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Yoshihiro","family":"Noyama","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Tsuyoshi","family":"Asano","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Tomohiro","family":"Shimizu","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Tohru","family":"Irie","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Mohamad Alaa","family":"Terkawi","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Norimasa","family":"Iwasaki","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"297","published-online":{"date-parts":[[2021,3,13]]},"reference":[{"issue":"5","key":"4152_CR1","doi-asserted-by":"publisher","first-page":"511","DOI":"10.1016\/0883-5403(94)90098-1","volume":"9","author":"MA Mont","year":"1994","unstructured":"Mont MA, Maar DC.
