Proximal loosening of the stem is presumed to simulate worst case conditions and replicates clinical failure. Load inclination, embedding level, load level and number of cycles are given by the test standard. The test conditions do provide safety information about fatigue failure of hip stems by a simplified model.<\/p>\n\n\n\n<p>The alignment of the hip stem versus the test load is straightforward for simple hip stem geometries but may be challenging for anatomic stems. EndoLab<sup>\u00ae<\/sup>&nbsp;has developed a 3D CAD based method to design custom AM-printed jigs for sample alignment.<br><br>The maximum test frequency depends on the flexibility of the stem and the performance of the test equipment. EndoLab<sup>\u00ae<\/sup>&nbsp;developed special tools to embed the stem correctly (see Fig.) which ensure constant loading of the implant. Most of our tests are performed using MTS<sup>\u00ae<\/sup>&nbsp;or Zwick<sup>\u00ae<\/sup>&nbsp;test equipment.<\/p>","protected":false},"featured_media":0,"template":"","meta":{"_acf_changed":true,"_uag_custom_page_level_css":""},"class_list":["post-2970","hip-implants","type-hip-implants","status-publish","hentry"],"acf":[],"uagb_featured_image_src":{"full":false,"thumbnail":false,"medium":false,"medium_large":false,"large":false,"1536x1536":false,"2048x2048":false,"trp-custom-language-flag":false},"uagb_author_info":{"display_name":"Simon Kaddick","author_link":"https:\/\/endolab.org\/de\/author\/"},"uagb_comment_info":0,"uagb_excerpt":"ISO\u00a07206-4:\u00a0Implants for surgery \u2013 Partial and total hip joint prostheses \u2013 Part 4: Determination of endurance properties and performance of stemmed femoral components ISO\u00a07206-6:\u00a0Implants for surgery \u2013 Partial and total hip joint prostheses \u2013 Part 6: Endurance properties testing and performance requirements of neck region of stemmed femoral components PI-58 (ISO\u00a07206-8):\u00a0Implants for surgery \u2013 Partial&hellip;","_links":{"self":[{"href":"https:\/\/endolab.org\/de\/wp-json\/wp\/v2\/hip-implants\/2970","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/endolab.org\/de\/wp-json\/wp\/v2\/hip-implants"}],"about":[{"href":"https:\/\/endolab.org\/de\/wp-json\/wp\/v2\/types\/hip-implants"}],"wp:attachment":[{"href":"https:\/\/endolab.org\/de\/wp-json\/wp\/v2\/media?parent=2970"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
