Multivariate logistic regression models examined the association between the surgeon groups and restoration of lateral femoral, acetabular offset, leg length discrepancy, acetabular anteversion, acetabular position, and component size, while adjusting for surgical approach and spinal pathology.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results:<\/jats:title>\n                    <jats:p>NAS under-restored 4.8\u2009mm of lateral femoral offset (43.9\u2009\u00b1\u20098.7\u2009mm) after THA when compared to the uninjured side (48.7\u2009\u00b1\u20097.1\u2009mm, p\u2009 =\u20090.044). NAS were at risk for under-restoring lateral femoral offset when compared to EAS ( p\u2009 =\u20090.040). There was no association between lateral acetabular offset, leg length, acetabular position, or component size and surgeon type.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusions:<\/jats:title>\n                    <jats:p>Lateral femoral offset is at risk for under-restoration after THA for femoral neck fractures, when performed by surgeons that do not regularly perform elective THA. This indicates that lateral femoral offset is an under-appreciated contributor to hip instability when performing THA for a femoral neck fracture. Lateral femoral offset deserves as much attention and awareness as acetabular component position since a secondary analysis of our data reveal that preoperative templating and intraoperative imaging did not prevent under-restoration.<\/jats:p>\n                  <\/jats:sec>","DOI":"10.1177\/11207000231169914","type":"journal-article","created":{"date-parts":[[2023,4,27]],"date-time":"2023-04-27T01:02:56Z","timestamp":1682557376000},"page":"134-143","update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":1,"title":["Arthroplasty for femoral neck fractures is at risk for under restoration of lateral femoral offset"],"prefix":"10.1177","volume":"34","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-4371-9205","authenticated-orcid":false,"given":"Harsh N","family":"Shah","sequence":"first","affiliation":[{"name":"Department of Orthopaedic Surgery, Stanford Medicine, Redwood City, CA, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Andrew A","family":"Barrett","sequence":"additional","affiliation":[{"name":"Department of Orthopaedic Surgery, Stanford Medicine, Redwood City, CA, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Andrea K","family":"Finlay","sequence":"additional","affiliation":[{"name":"Department of Orthopaedic Surgery, Stanford Medicine, Redwood City, CA, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Prerna","family":"Arora","sequence":"additional","affiliation":[{"name":"Department of Orthopaedic Surgery, Stanford Medicine, Redwood City, CA, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Michael J","family":"Bellino","sequence":"additional","affiliation":[{"name":"Department of Orthopaedic Surgery, Stanford Medicine, Redwood City, CA, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Julius A","family":"Bishop","sequence":"additional","affiliation":[{"name":"Department of Orthopaedic Surgery, Stanford Medicine, Redwood City, CA, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Michael J","family":"Gardner","sequence":"additional","affiliation":[{"name":"Department of Orthopaedic Surgery, Stanford Medicine, Redwood City, CA, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Matthew D","family":"Miller","sequence":"additional","affiliation":[{"name":"Department of Orthopaedic Surgery, Stanford Medicine, Redwood City, CA, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"suffix":"3rd","given":"James I","family":"Huddleston","sequence":"additional","affiliation":[{"name":"Department of Orthopaedic Surgery, Stanford Medicine, Redwood City, CA, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"William J","family":"Maloney","sequence":"additional","affiliation":[{"name":"Department of Orthopaedic Surgery, Stanford Medicine, Redwood City, CA, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Stuart B","family":"Goodman","sequence":"additional","affiliation":[{"name":"Department of Orthopaedic Surgery, Stanford Medicine, Redwood City, CA, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-6203-5853","authenticated-orcid":false,"given":"Derek F","family":"Amanatullah","sequence":"additional","affiliation":[{"name":"Department of Orthopaedic Surgery, Stanford Medicine, Redwood City, CA, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"179","published-online":{"date-parts":[[2023,4,26]]},"reference":[{"key":"bibr1-11207000231169914","doi-asserted-by":"publisher","DOI":"10.1007\/s00198-006-0172-4"},{"key":"bibr2-11207000231169914","doi-asserted-by":"publisher","DOI":"10.1007\/PL00004148"},{"key":"bibr3-11207000231169914","doi-asserted-by":"publisher","DOI":"10.1016\/j.afos.2018.03.003"},{"key":"bibr4-11207000231169914","doi-asserted-by":"publisher","DOI":"10.1001\/jama.2009.1462"},{"key":"bibr5-11207000231169914","doi-asserted-by":"publisher","DOI":"10.1136\/bmj.327.7418.771"},{"key":"bibr6-11207000231169914","doi-asserted-by":"publisher","DOI":"10.4055\/cios.2012.4.2.117"},{"key":"bibr7-11207000231169914","doi-asserted-by":"publisher","DOI":"10.1007\/s00264-012-1569-7"},{"key":"bibr8-11207000231169914","doi-asserted-by":"publisher","DOI":"10.3310\/hta9410"},{"key":"bibr9-11207000231169914","doi-asserted-by":"publisher","DOI":"10.1097\/01.blo.0000150273.13949.62"},{"key":"bibr10-11207000231169914","doi-asserted-by":"publisher","DOI":"10.1007\/s11999-012-2250-6"},{"key":"bibr11-11207000231169914","doi-asserted-by":"publisher","DOI":"10.1186\/s12891-015-0696-x"},{"key":"bibr12-11207000231169914","unstructured":"National Institute for Health and Care Excellence.
