Another four horses (2 Thoroughbred racehorses, 1 Standardbred racehorse, 1 Warmblood) had haemarthrosis of the tarsocrural joint and presented with mild, intermittent lameness (median, grade 1) and marked, persistent joint effusion. Six of the eight horses had recurrent haemarthrosis prior to treatment. Radiographic and nuclear scintigraphic examinations did not identify bone pathology. Diagnostic arthroscopy (7 cases) identified grossly hypertrophied yellow\/brown discoloured synovium. Synovial histopathology of these cases revealed chronic synovial hyperplasia with severe haemosiderosis and granulomatous inflammatory reaction of varying severity. All horses underwent rest, bandaging and phenylbutazone administration. Two horses had subtotal mechanical synovectomy, four horses had intra\u2010articular administration of <jats:sup>90<\/jats:sup>Y and MPA, and one horse underwent both treatments. Seven cases returned to their previous use (median time, 7 months). Haemarthrosis recurred in three horses, two of which had received the <jats:sup>90<\/jats:sup>Y and MPA treatment.<\/jats:p><jats:p><jats:bold>Conclusion\u2003<\/jats:bold> Idiopathic haemarthrosis should be considered a differential for acute and recurrent joint related lameness and effusion. Recurrence appears not uncommon and the use of intra\u2010articular <jats:sup>90<\/jats:sup>Y and MPA in conjunction with a conservative management treatment protocol warrants further evaluation.<\/jats:p>","DOI":"10.1111\/j.1751-0813.2012.00935.x","type":"journal-article","created":{"date-parts":[[2012,5,28]],"date-time":"2012-05-28T01:38:41Z","timestamp":1338169121000},"page":"214-220","update-policy":"http:\/\/dx.doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":12,"title":["Idiopathic haemarthrosis in eight horses"],"prefix":"10.1111","volume":"90","author":[{"given":"SA","family":"Vallance","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"JM","family":"Lumsden","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"AP","family":"Begg","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"CB","family":"O'Sullivan","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","published-online":{"date-parts":[[2012,5,27]]},"reference":[{"key":"e_1_2_7_2_2","doi-asserted-by":"publisher","DOI":"10.1016\/B978-0-7216-8342-3.50074-7"},{"key":"e_1_2_7_3_2","doi-asserted-by":"publisher","DOI":"10.1111\/j.2042-3306.1992.tb02857.x"},{"key":"e_1_2_7_4_2","first-page":"175","article-title":"Intra\u2010carpal ligament damage as a cause of lameness in the horse","volume":"12","author":"Kannegieter NJ","year":"1990","journal-title":"Proceedings Bain Fallon Memorial Lectures"},{"key":"e_1_2_7_5_2","first-page":"519","article-title":"Trauma resulting in hemarthrosis and long medial collateral ligament desmitis of the tarsocrural joint in a horse","volume":"52","author":"Tokateloff N","year":"2011","journal-title":"Can Vet J"},{"key":"e_1_2_7_6_2","volume-title":"The practice of large animal surgery","author":"Fessler J","year":"1984"},{"key":"e_1_2_7_7_2","doi-asserted-by":"publisher","DOI":"10.1016\/S0883-5403(05)80231-1"},{"key":"e_1_2_7_8_2","doi-asserted-by":"publisher","DOI":"10.1111\/j.1365-2141.2008.07386.x"},{"key":"e_1_2_7_9_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.semarthrit.2010.07.005"},{"key":"e_1_2_7_10_2","doi-asserted-by":"publisher","DOI":"10.1111\/j.2042-3306.1986.tb03606.x"},{"key":"e_1_2_7_11_2","doi-asserted-by":"publisher","DOI":"10.2460\/ajvr.2005.66.1084"},{"key":"e_1_2_7_12_2","doi-asserted-by":"publisher","DOI":"10.1136\/ard.28.4.402"},{"key":"e_1_2_7_13_2","doi-asserted-by":"publisher","DOI":"10.1136\/ard.50.8.588"},{"key":"e_1_2_7_14_2","doi-asserted-by":"publisher","DOI":"10.1302\/0301-620X.63B4.7298694"},{"key":"e_1_2_7_15_2","doi-asserted-by":"publisher","DOI":"10.1136\/ard.52.1.67"},{"key":"e_1_2_7_16_2","doi-asserted-by":"publisher","DOI":"10.1111\/j.1365-2516.2005.01175.x"},{"key":"e_1_2_7_17_2","first-page":"48","article-title":"Radiosynovectomy in rheumatology, orthopedics and hemophilia","volume":"46","author":"Schneider P","year":"2005","journal-title":"J Nucl Med"},{"key":"e_1_2_7_18_2","doi-asserted-by":"publisher","DOI":"10.1093\/rheumatology\/41.10.1113"},{"key":"e_1_2_7_19_2","doi-asserted-by":"publisher","DOI":"10.1111\/j.1365-2516.2010.02276.x"},{"key":"e_1_2_7_20_2","doi-asserted-by":"publisher","DOI":"10.1111\/j.1538-7836.2011.04246.x"},{"key":"e_1_2_7_21_2","first-page":"1197","article-title":"Pigmented villonodular synovitis managed by Yttrium 90 after debulking surgery","volume":"29","author":"Ozturk H","year":"2008","journal-title":"Saudi Med J"},{"key":"e_1_2_7_22_2","first-page":"19","volume-title":"Guide for veterinary services and judging of equestrian events","author":"Kester WO","year":"1991"},{"key":"e_1_2_7_23_2","doi-asserted-by":"publisher","DOI":"10.1016\/B978-0-7234-3281-4.50008-7"},{"key":"e_1_2_7_24_2","unstructured":"Ozeform Web site.
