Hips with more severe necrosis, Catterall groups III and IV, had moderate or intense degrees of synovitis. There was a correlation between the degree of synovitis and the lateral pillar classification according to HERRING et al. Also, there was a good correlation between the extent of signal changes in the epiphysis on MR imaging and the degree of synovitis. There was no difference when signal changes were evaluated on T1- or T2-weighted images. Signs of synovitis could be seen for up to 30 months after diagnosis in Catterall group I hips, and in Catterall groups II and III for up to 36 months, and in 2 cases even longer. Some Catterall group IV hips had discreet or mild synovitis for 60 months or more, after diagnosis<\/jats:p>\n                  <jats:p>Conclusion: the degree of synovitis on MR imaging correlates to the extent of epiphyseal necrosis seen on radiographs or MR imaging as well as to the lateral pillar classification, i.e. to a poor clinical outcome. in Catterall group IV hips, synovitis can even persist for up to 60 months after diagnosis<\/jats:p>","DOI":"10.1080\/02841859809172220","type":"journal-article","created":{"date-parts":[[2010,1,4]],"date-time":"2010-01-04T11:03:57Z","timestamp":1262603037000},"page":"532-537","source":"Crossref","is-referenced-by-count":7,"title":["Synovitis in legg-calv\u00e9-perthes disease"],"prefix":"10.1177","volume":"39","author":[{"given":"P.","family":"Hochbergs","sequence":"first","affiliation":[{"name":"Department of Diagnostic Radiology, University Hospital, Lund, Sweden"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"G.","family":"Eckerwall","sequence":"additional","affiliation":[{"name":"Department of Orthopedics, University Hospital, Lund, Sweden"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"N.","family":"Egund","sequence":"additional","affiliation":[{"name":"Department of Diagnostic Radiology, University Hospital, \u00c5rhus, Denmark"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"K.","family":"Jonsson","sequence":"additional","affiliation":[{"name":"Department of Diagnostic Radiology, University Hospital, Lund, Sweden"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"H.","family":"Wingstrand","sequence":"additional","affiliation":[{"name":"Department of Orthopedics, University Hospital, Lund, Sweden"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"179","published-online":{"date-parts":[[2016,8,30]]},"container-title":["Acta Radiologica"],"original-title":[],"language":"en","link":[{"URL":"http:\/\/journals.sagepub.com\/doi\/pdf\/10.1080\/02841859809172220","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"http:\/\/journals.sagepub.com\/doi\/pdf\/10.1080\/02841859809172220","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2026,4,28]],"date-time":"2026-04-28T13:38:00Z","timestamp":1777383480000},"score":1,"resource":{"primary":{"URL":"http:\/\/journals.sagepub.com\/doi\/10.1080\/02841859809172220"}},"subtitle":["Evaluation with MR imaging in 84 hips"],"short-title":[],"issued":{"date-parts":[[1998,9]]},"references-count":0,"journal-issue":{"issue":"5","published-print":{"date-parts":[[1998,9]]}},"alternative-id":["10.1080\/02841859809172220"],"URL":"https:\/\/doi.org\/10.1080\/02841859809172220","relation":{},"ISSN":["0284-1851","1600-0455"],"issn-type":[{"value":"0284-1851","type":"print"},{"value":"1600-0455","type":"electronic"}],"subject":[],"published":{"date-parts":[[1998,9]]}}}
