Shorter length stems have shown to decrease stress shielding; however, the effect of stem varus\u2013valgus alignment is currently not known. The purpose of this study was to quantify the effect of short stem distal humeral endosteal contact due to varus\u2013valgus angulation on bone stresses after TSA. Three\u2010dimensional models of eight male cadaveric humeri were constructed from computed tomography data. Bone models were reconstructed with a short stem humeral component implant in three positions (standard, varus, and valgus). Modeling was performed at 45\u00b0 and 75\u00b0 of abduction and the resulting differentials in bone stress compared to the intact state and the expected time\u2010zero bone response were determined. In cortical and trabecular bone, the standard position (STD) altered bone stress less than the valgus (VAL) and varus (VAR) positions relative to the intact state. For both cortical (<jats:italic>p<\/jats:italic>\u2009=\u20090.033) and trabecular (<jats:italic>p<\/jats:italic>\u2009=\u20090.012) bone, the VAL position produced a larger volume of bone with resorbing potential compared to the STD position.<\/jats:p>","DOI":"10.1002\/jor.25239","type":"journal-article","created":{"date-parts":[[2021,12,16]],"date-time":"2021-12-16T15:28:07Z","timestamp":1639668487000},"page":"2169-2178","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":13,"title":["Humeral short stem varus\u2013valgus alignment affects bone stress"],"prefix":"10.1002","volume":"40","author":[{"given":"Amir","family":"Tavakoli","sequence":"first","affiliation":[{"name":"Department of Mechanical and Materials Engineering The University of Western Ontario London Ontario Canada"},{"name":"Roth McFarlane Hand and Upper Limb Center St. Joseph's Health Care London London Ontario Canada"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Gregory","family":"Spangenberg","sequence":"additional","affiliation":[{"name":"Department of Mechanical and Materials Engineering The University of Western Ontario London Ontario Canada"},{"name":"Roth McFarlane Hand and Upper Limb Center St. Joseph's Health Care London London Ontario Canada"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jacob M.","family":"Reeves","sequence":"additional","affiliation":[{"name":"Department of Mechanical and Materials Engineering The University of Western Ontario London Ontario Canada"},{"name":"Roth McFarlane Hand and Upper Limb Center St. Joseph's Health Care London London Ontario Canada"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Kenneth J.","family":"Faber","sequence":"additional","affiliation":[{"name":"Department of Mechanical and Materials Engineering The University of Western Ontario London Ontario Canada"},{"name":"Roth McFarlane Hand and Upper Limb Center St. Joseph's Health Care London London Ontario Canada"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-8164-0605","authenticated-orcid":false,"given":"G.
