Radiographs at day 5 demonstrated superolateral displacement of the left femur, initially interpreted as a congenital hip dislocation. Ultrasound imaging demonstrated a normally positioned femoral head with no acetabular dysplasia, and repeat radiographs at 2-weeks revealed callus formation. Separation of the proximal femoral epiphysis was suspected and subsequently confirmed with magnetic resonance imaging. No active intervention was recommended, and 1-year radiographs demonstrated satisfactory remodeling.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion:<\/jats:title>\n                    <jats:p>This report highlights the diagnostic challenges around this rare birth-related injury and demonstrates the excellent remodeling potential of the neonatal hip.<\/jats:p>\n                  <\/jats:sec>","DOI":"10.2106\/jbjs.cc.24.00581","type":"journal-article","created":{"date-parts":[[2025,4,25]],"date-time":"2025-04-25T14:00:42Z","timestamp":1745589642000},"update-policy":"https:\/\/doi.org\/10.1097\/lww.0000000000001000","source":"Crossref","is-referenced-by-count":0,"title":["Birth-Related Traumatic Proximal Femoral Physeal Separation"],"prefix":"10.2106","volume":"15","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-3370-8174","authenticated-orcid":false,"given":"Luckshman","family":"Bavan","sequence":"first","affiliation":[{"name":"The Hospital for Sick Children, Toronto, Ontario, Canada"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-8728-2781","authenticated-orcid":false,"given":"Shu Yang","family":"Hu","sequence":"additional","affiliation":[{"name":"The Hospital for Sick Children, Toronto, Ontario, Canada"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-8458-2033","authenticated-orcid":false,"given":"Simon","family":"Kelley","sequence":"additional","affiliation":[{"name":"Texas Children's Hospital, Houston, Texas"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Richard","family":"Gardner","sequence":"additional","affiliation":[{"name":"The Hospital for Sick Children, Toronto, Ontario, Canada"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"276","published-online":{"date-parts":[[2025,4]]},"reference":[{"key":"bib1-20250425","doi-asserted-by":"crossref","first-page":"238","DOI":"10.3109\/17453676408989320","article-title":"Traumatic separation of the upper femoral epiphysis as an obstetrical lesion","volume":"34","author":"Mortens","year":"1964","journal-title":"Acta Orthop Scand."},{"issue":"3","key":"bib2-20250425","doi-asserted-by":"crossref","first-page":"456","DOI":"10.1542\/peds.63.3.456","article-title":"Neonatal traumatic proximal femoral epiphysiolysis","volume":"63","author":"Towbin","year":"1979","journal-title":"Pediatrics."},{"issue":"6","key":"bib3-20250425","first-page":"595","article-title":"Apparent or true neonatal hip dislocation?
