Orthopedic\u00a0examination and radiography excluded fractures. Ultrasonography revealed a large mixed hypo- and hyperechoic collection,with no Doppler signal, but with comet tail artifacts. Repeated cultures from the collection were negative. Fluid analysis revealed\u00a0increased quantities of titanium and cobalt. The sudden-onset deformity and fluid collection were in favor of a shear\u00a0lesion (Morel-Lavall\u00e9e). The new collection communicated with a previously asymptomatic periprosthetic aseptic abscess,\u00a0mimicking an infection. To our knowledge, Morel-Lavall\u00e9e shear lesions have not been described in patients with hip prostheses.\u00a0Their presence may add to the difficulties of ruling out silent infections in such patients. Ultrasonography is a very\u00a0effective method for the diagnosis and follow-up of collections in this setting.<\/jats:p>","DOI":"10.11152\/mu-1748","type":"journal-article","created":{"date-parts":[[2018,11,15]],"date-time":"2018-11-15T07:46:45Z","timestamp":1542268005000},"page":"191","source":"Crossref","is-referenced-by-count":0,"title":["Posttraumatic hip bulging mimicking an abscess in a patient with hip prosthesis: the role of ultrasonography"],"prefix":"10.11152","volume":"21","author":[{"given":"Laura Otilia","family":"Damian","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Siao-pin","family":"Simon","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Ioana","family":"Felea","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Mihaela","family":"Coman","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Daniela","family":"Fodor","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Cezara Mariana","family":"Voica","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"4840","published-online":{"date-parts":[[2019,5,2]]},"container-title":["Medical Ultrasonography"],"original-title":[],"link":[{"URL":"https:\/\/medultrason.ro\/medultrason\/index.php\/medultrason\/article\/viewFile\/1748\/1334","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/medultrason.ro\/medultrason\/index.php\/medultrason\/article\/viewFile\/1748\/1334","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2019,5,6]],"date-time":"2019-05-06T10:47:09Z","timestamp":1557139629000},"score":1,"resource":{"primary":{"URL":"https:\/\/medultrason.ro\/medultrason\/index.php\/medultrason\/article\/view\/1748"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2019,5,2]]},"references-count":0,"journal-issue":{"issue":"2","published-online":{"date-parts":[[2019,5,2]]}},"URL":"https:\/\/doi.org\/10.11152\/mu-1748","relation":{},"ISSN":["2066-8643","1844-4172"],"issn-type":[{"value":"2066-8643","type":"electronic"},{"value":"1844-4172","type":"print"}],"subject":[],"published":{"date-parts":[[2019,5,2]]}}}
