The goal of this retrospective study is to offer a definition of this rare sign, evaluate its incidence of occurrence and compare the sonographic findings with the clinical findings.<\/jats:p><jats:p>\n          Materials and Methods This Double-Head-Sign is caused by the overlap of the trochanter major with the actual head of the femur in cases of coxa vara. This was observed in 13 of 2800 neonates we screened as part of our sonographical neonatal hip screening.<\/jats:p><jats:p>\n          Results 13 neonates presented themselves with ultrasound findings in accordance with our description, yielding an incidence of 0,46% in our patient cohort. In correlation, these neonates also exhibited increased external and decreased internal rotation of the hip. Two had an underlying condition (achondroplasia).<\/jats:p><jats:p>\n          Conclusion In these rare cases, clinical examination of hip rotation in 90\u00b0 hip flexion has proved helpful and further interdisciplinary examination of such infants to distinguish a possible underlying primary condition is recommended<\/jats:p>","DOI":"10.1055\/a-0972-1956","type":"journal-article","created":{"date-parts":[[2019,10,21]],"date-time":"2019-10-21T22:53:12Z","timestamp":1571698392000},"page":"462-465","source":"Crossref","is-referenced-by-count":3,"title":["The Phenomenon of the Apparent (Double) Femoral Head in Infant Hip Sonography According to Graf-Description, Incidence and Clinical Relevance"],"prefix":"10.1055","volume":"158","author":[{"given":"Charlotte","family":"Struwe","sequence":"additional","affiliation":[{"name":"Clinic and Polyclinic for Orthopedics and Trauma Surgery, University Hospital Bonn"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Rahel","family":"Bornemann","sequence":"additional","affiliation":[{"name":"Clinic and Polyclinic for Orthopedics and Trauma Surgery, University Hospital Bonn"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Sebastian Gottfried","family":"Walter","sequence":"additional","affiliation":[{"name":"Clinic and Polyclinic for Orthopedics and Trauma Surgery, University Hospital Bonn"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Sebastian","family":"Koob","sequence":"additional","affiliation":[{"name":"Clinic and Polyclinic for Orthopedics and Trauma Surgery, University Hospital Bonn"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Richard","family":"Placzek","sequence":"additional","affiliation":[{"name":"Clinic and Polyclinic for Orthopedics and Trauma Surgery, University Hospital Bonn"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"194","published-online":{"date-parts":[[2019,10,21]]},"reference":[{"key":"ref1","first-page":"57","article-title":"Leitlinie f\u00fcr das h\u00fcftsonographische Screening im Rahmen des Programms Krankheitsfr\u00fcherkennung im Kindesalter, Leitlinie Konsensusstatement","volume":"93","author":"L Altenhofen","year":"1996","journal-title":"Dtsch \u00c4rztebl"},{"key":"ref2","volume-title":"Hip Sonography: Diagnosis and Management of Infant Hip Dysplasia","author":"R Graf","year":"2006"},{"key":"ref3","first-page":"36","article-title":"Ultrasonography in developmental dysplasia of the hip: a review of current clinical strategies and recommendations for revision of practice","volume":"2","author":"K Chlapoutakis","year":"2017","journal-title":"Hell J Radiol"},{"key":"ref4","first-page":"417","article-title":"[Congenital hip dysplasia in newborns: clinical and ultrasound examination, arthrography and closed reduction]","volume":"25","author":"R Placzek","year":"2013","journal-title":"Oper Orthop Traumatol"},{"key":"ref5","doi-asserted-by":"crossref","first-page":"588","DOI":"10.1097\/01241398-200009000-00009","article-title":"Ultrasonographic evaluation of hip morphology in osteochondrodysplasias","volume":"20","author":"M P De Pellegrin","year":"2000","journal-title":"J Pediatr Orthop"}],"container-title":["Zeitschrift f\u00fcr Orthop\u00e4die und Unfallchirurgie"],"original-title":[],"language":"de","link":[{"URL":"http:\/\/www.thieme-connect.de\/products\/ejournals\/pdf\/10.1055\/a-0972-1956.pdf","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2020,10,1]],"date-time":"2020-10-01T22:35:55Z","timestamp":1601591755000},"score":1,"resource":{"primary":{"URL":"http:\/\/www.thieme-connect.de\/DOI\/DOI?10.1055\/a-0972-1956"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2019,10,21]]},"references-count":5,"journal-issue":{"issue":"05","published-online":{"date-parts":[[2020,10,1]]},"published-print":{"date-parts":[[2020,10]]}},"URL":"https:\/\/doi.org\/10.1055\/a-0972-1956","relation":{},"ISSN":["1864-6697","1864-6743"],"issn-type":[{"value":"1864-6697","type":"print"},{"value":"1864-6743","type":"electronic"}],"subject":[],"published":{"date-parts":[[2019,10,21]]}}}
