The tested implants were divided into four different groups (eight-Plate\u00ae vs. FlexTack<jats:sup>TM<\/jats:sup> for lateral and anterior implantation) \u00e1 10 samples for testing implanted eight-Plate\u00ae vs. FlexTack<jats:sup>TM<\/jats:sup> in fresh frozen pig femora for maximum load forces (<jats:italic>F<\/jats:italic><jats:sub>max<\/jats:sub>) and axial physis distance until implant failure (<jats:italic>l<\/jats:italic><jats:sub>max<\/jats:sub>). A servo hydraulic testing machine (858 Mini Bionix 2) was used to exert and measure reproducible forces. Statistical analyses tested for normal distribution and significant (<jats:italic>p<\/jats:italic>\u2009&lt;\u20090.05) differences in primary outcome parameters. There were no significant differences between the eight-Plate\u00ae lateral group and the FlexTack<jats:sup>TM<\/jats:sup> lateral group for neither <jats:italic>F<\/jats:italic><jats:sub>max<\/jats:sub> (<jats:italic>p<\/jats:italic>\u2009=\u20090.46) nor <jats:italic>l<\/jats:italic><jats:sub>max<\/jats:sub> (<jats:italic>p<\/jats:italic>\u2009=\u20090.65). There was a significant higher <jats:italic>F<\/jats:italic><jats:sub>max<\/jats:sub> (<jats:italic>p<\/jats:italic>\u2009&lt;\u20090.001) and <jats:italic>l<\/jats:italic><jats:sub>max<\/jats:sub> (<jats:italic>p<\/jats:italic>\u2009=\u20090.001) measured in the eight-Plate\u00ae group compared to the FlexTack<jats:sup>TM<\/jats:sup> group when implanted anteriorly. In anterior temporary ephiphysiodesis, eight-Plate\u00ae demonstrated superior biomechanical stability. At this stage of research, there is no clear advantage of either implant and the choice remains within the individual preference of the surgeon.<\/jats:p>","DOI":"10.1007\/s10856-021-06515-9","type":"journal-article","created":{"date-parts":[[2021,4,1]],"date-time":"2021-04-01T15:09:43Z","timestamp":1617289783000},"update-policy":"https:\/\/doi.org\/10.1007\/springer_crossmark_policy","source":"Crossref","is-referenced-by-count":2,"title":["Biomechanical evaluation of temporary epiphysiodesis at the femoral epiphysis using established devices from clinical practice"],"prefix":"10.1007","volume":"32","author":[{"given":"Charlotte","family":"Struwe","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-6203-8616","authenticated-orcid":false,"given":"Sebastian G.","family":"Walter","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Claudia","family":"Druschel","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Rahel","family":"Bornemann","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Milena","family":"Ploeger","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Sebastian","family":"Koob","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Richard","family":"Placzek","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"297","published-online":{"date-parts":[[2021,4,1]]},"reference":[{"key":"6515_CR1","first-page":"629","volume":"81","author":"O Oest","year":"1978","unstructured":"Oest O.
