He rated his pain as 8\/10 with pitching, especially at the late cocking phase of throwing. Prior to consult, he had rested 3 months from pitching, progressing to strengthening exercises, with no pain relief. On physical examination, he had 120\u00b0 of active external rotation, 80\u00b0 of active internal rotation, mild tenderness to palpation over the capitellum and normal elbow radiography. Magnetic resonance arthrogram of the right elbow revealed subtle, posterolateral joint capsular tear and adjacent synovial hypertrophy. The patient was diagnosed with elbow synovial fold syndrome that was causing impingement at the radiocapitellar joint and was referred to an orthopaedic surgeon. Arthroscopy revealed redundant tissue; scar formation at the radiocapitellar joint was debrided. The patient participated in physical therapy for 2 months and was able to start throwing 3 months later.<\/jats:p>","DOI":"10.1136\/bcr-2018-224287","type":"journal-article","created":{"date-parts":[[2018,6,30]],"date-time":"2018-06-30T02:25:12Z","timestamp":1530325512000},"page":"bcr-2018-224287","update-policy":"https:\/\/doi.org\/10.1136\/crossmarkpolicy","source":"Crossref","is-referenced-by-count":5,"title":["Unusual cause of elbow pain in a baseball pitcher"],"prefix":"10.1136","volume":"2018","author":[{"given":"Nithin","family":"Natwa","sequence":"first","affiliation":[{"name":"Sports Medicine, Michigan State University, East Lansing, Michigan, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Alan","family":"Zakaria","sequence":"additional","affiliation":[{"name":"Internal Medicine, Oakland University William Beaumont School of Medicine, Rochester, Michigan, USA"},{"name":"Pediatrics, Oakland University William Beaumont School of Medicine, Rochester, Michigan, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-7537-7457","authenticated-orcid":false,"given":"George","family":"Pujalte","sequence":"additional","affiliation":[{"name":"Sports Medicine, Mayo Clinic, Jacksonville, FL, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"239","published-online":{"date-parts":[[2018,6,29]]},"reference":[{"key":"2025082701194321000_2018.jun29_2.bcr-2018-224287.1","first-page":"xii","article-title":"Elbow synovial fold syndrome","volume":"172","author":"Sanghi","year":"2007","journal-title":"Mil Med"},{"key":"2025082701194321000_2018.jun29_2.bcr-2018-224287.2","doi-asserted-by":"crossref","first-page":"W88","DOI":"10.2214\/AJR.12.8768","article-title":"Elbow synovial fold syndrome","volume":"201","author":"Cerezal","year":"2013","journal-title":"AJR Am J Roentgenol"},{"key":"2025082701194321000_2018.jun29_2.bcr-2018-224287.3","doi-asserted-by":"publisher","DOI":"10.1007\/s00402-008-0798-0"},{"key":"2025082701194321000_2018.jun29_2.bcr-2018-224287.4","doi-asserted-by":"crossref","first-page":"1263","DOI":"10.1007\/s00247-012-2407-1","article-title":"Elbow plica syndrome: presenting with elbow locking in a pediatric patient","volume":"42","author":"Meyers","year":"2012","journal-title":"Pediatr Radiol"},{"key":"2025082701194321000_2018.jun29_2.bcr-2018-224287.5","doi-asserted-by":"crossref","first-page":"155","DOI":"10.11152\/mu.2013.2066.172.usev","article-title":"Ultrasonographic evaluation of the posterolateral radiohumeral plica in asymptomatic subjects and in patients with osteoarthritis","volume":"17","author":"Celikyay","year":"2015","journal-title":"Med Ultrason"},{"key":"2025082701194321000_2018.jun29_2.bcr-2018-224287.6","doi-asserted-by":"publisher","DOI":"10.1148\/radiol.10092163"},{"key":"2025082701194321000_2018.jun29_2.bcr-2018-224287.7","unstructured":"Jayanthi N .
