Some studies suggest a link between hip clicks and developmental dysplasia of the hip. The purpose of our study is to estimate the prevalence of ultrasound hip abnormalities in newborns with a hip click and an otherwise normal physical examination. Results. Ninety patients meeting inclusion criteria of a hip click with an otherwise normal physical examination underwent diagnostic ultrasound with a 17.8% prevalence of hip abnormalities found (95% confidence interval \u00b17.9% [range of 9.9% to 25.7%]). Our study had 64 (71%) females and 26 (29%) males. The prevalence of hip pathology for females was 18.8% (12 of 64 patients) and for males was 15.4% (4 of 26 patients). Thirty-three patients were found to have bilateral hip clicks on presentation, with 21.2% (7 of 33) of those patients found to have hip pathology on ultrasound (3 of the 7 had pathology of both hips). Six patients had a family history of hip dysplasia and 1 of these patients (16.7%) had pathology on ultrasound. The average age to hip sonography was 6.6 weeks. Conclusions. In all, 17.8% of newborns with a hip click were found to have hip abnormalities on ultrasound. The prevalence of hip pathology, on ultrasound, suggests that additional larger, prospective studies are needed to clarify the association between a hip click and abnormal ultrasound found at 6 weeks of age or greater.<\/jats:p>","DOI":"10.1177\/0009922820920011","type":"journal-article","created":{"date-parts":[[2020,5,11]],"date-time":"2020-05-11T07:47:03Z","timestamp":1589183223000},"page":"773-777","update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":2,"title":["Prevalence of Hip Ultrasound Abnormalities in Newborns With a Hip Click"],"prefix":"10.1177","volume":"59","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-2877-4107","authenticated-orcid":false,"given":"John T.","family":"Gaffney","sequence":"first","affiliation":[{"name":"NYU Winthrop Hospital, Garden City, NY, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"John","family":"Spellman","sequence":"additional","affiliation":[{"name":"Stony Brook University Hospital, Stony Brook, NY, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"179","published-online":{"date-parts":[[2020,5,11]]},"reference":[{"key":"bibr1-0009922820920011","unstructured":"International Hip Dysplasia Institute.
