This change in sagittal pelvic tilt (SPT) can result in prosthetic impingement and dislocation. Our aim was to determine the magnitude of SPT change that could lead to prosthetic impingement. We hypothesized that the magnitude of SPT change that could lead to THA dislocation is less than 10\u00b0 and it varies for different hip motions. Hip motion was simulated in standing, sitting, sit\u2010to\u2010stand, bending forward, squatting and pivoting in Matlab software. The implant orientations and SPT angle were modified by 1\u00b0 increments. The risk of prosthetic impingement in pivoting caused by increased pelvic retroversion (reciever operating characteristic [ROC] threshold as low as 1\u20133\u00b0) is higher than the risk of prosthetic impingement with increased pelvic anteversion (ROC threshold as low as 16\u201318\u00b0). Larger femoral heads decrease the risk of prosthetic impingement (odds ratio {OR}: 0.08 [932\u2009mm head]; OR: 0.01 [36\u2009mm head]; OR: 0.002 [40\u2009mm head]). Femoral stems with a higher neck\u2010shaft angle decrease the prosthetic impingement due to SPT change in motions requiring hip flexion (OR: 1.16 [132\u00b0 stem]; OR: 4.94 [135\u00b0 stem]). Our results show that overall, the risk of prosthetic impingement due to SPT change is low. In particular, this risk is very low when a larger diameter head is used and femoral offset and length are recreated to prevent bone on bone impingement.<\/jats:p>","DOI":"10.1002\/jor.25022","type":"journal-article","created":{"date-parts":[[2021,3,22]],"date-time":"2021-03-22T11:05:09Z","timestamp":1616411109000},"page":"2604-2614","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":10,"title":["How much change in pelvic sagittal tilt can result in hip dislocation due to prosthetic impingement?
