Bilateral diagnostic ultrasound measured CHD, HR, and posterior capsule thickness (PCT), and quantified subscapularis tendon organization. External rotation, neutral, and crossbody CHD was measured.<\/jats:p>\n <\/jats:sec>\n \n Results:<\/jats:title>\n \n Overall, 52 healthy professional baseball pitchers participated. The dominant arm of pitchers demonstrated a significantly narrower CHD in all 3 positions (\n P<\/jats:italic>\n < 0.01), increased scapular protraction (163 vs 156 mm;\n P<\/jats:italic>\n < 0.01), and increased spatial frequency of the subscapularis tendon (1.8 vs 1.6 peaks\/mm;\n P<\/jats:italic>\n < 0.01). HR was associated with CHD in 30\u00b0 of external rotation (\n R<\/jats:italic>\n 2<\/jats:sup>\n = 0.12;\n P<\/jats:italic>\n < 0.01), neutral rotation (\n R<\/jats:italic>\n 2<\/jats:sup>\n = 0.11;\n P<\/jats:italic>\n < 0.01), and the crossbody position (\n R<\/jats:italic>\n 2<\/jats:sup>\n = 0.28;\n P<\/jats:italic>\n < 0.01). PCT was associated with CHD in 30\u00b0 of external rotation (\n R<\/jats:italic>\n 2<\/jats:sup>\n = 0.16;\n P<\/jats:italic>\n = 0.05). HR and CHD in 30\u00b0 of external rotation was associated most strongly with subscapularis tendon organization (\n R<\/jats:italic>\n 2<\/jats:sup>\n = 0.11;\n P<\/jats:italic>\n = 0.03).\n <\/jats:p>\n <\/jats:sec>\n \n Conclusion:<\/jats:title>\n The dominant shoulder of professional pitchers presents with a smaller CHD, more scapular protraction, and more subscapularis tendon disorganization than the nondominant shoulder.<\/jats:p>\n <\/jats:sec>\n \n Clinical Relevance:<\/jats:title>\n Professional pitchers demonstrate chronic CHD and subscapularis tendon adaptations, which may increase their risk for anterior shoulder pain and subscapularis tendon injury.<\/jats:p>\n <\/jats:sec>","DOI":"10.1177\/19417381241270359","type":"journal-article","created":{"date-parts":[[2024,8,14]],"date-time":"2024-08-14T08:19:17Z","timestamp":1723623557000},"page":"752-758","update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":1,"title":["Chronic Adaptation of the Coracohumeral Space and Subscapularis Tendon in Professional Baseball Pitchers"],"prefix":"10.1177","volume":"17","author":[{"given":"Matthew R.","family":"Schofield","sequence":"first","affiliation":[{"name":"Boise State University, Boise, Idaho"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-6846-3349","authenticated-orcid":false,"given":"Ryan W.","family":"Paul","sequence":"additional","affiliation":[{"name":"Rothman Orthopaedics, Philadelphia, Pennsylvania"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Paul","family":"Buchheit","sequence":"additional","affiliation":[{"name":"Philadelphia Phillies, Philadelphia, Pennsylvania"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Joseph","family":"Rauch","sequence":"additional","affiliation":[{"name":"Philadelphia Phillies, Philadelphia, Pennsylvania"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Stephen J.","family":"Thomas","sequence":"additional","affiliation":[{"name":"Thomas Jefferson University, Philadelphia, Pennsylvania"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"179","published-online":{"date-parts":[[2024,8,14]]},"reference":[{"key":"e_1_3_2_2_2","doi-asserted-by":"publisher","DOI":"10.1007\/s00590-014-1490-4"},{"key":"e_1_3_2_3_2","doi-asserted-by":"publisher","DOI":"10.1002\/jor.20347"},{"key":"e_1_3_2_4_2","doi-asserted-by":"publisher","DOI":"10.12659\/MSM.911470"},{"key":"e_1_3_2_5_2","doi-asserted-by":"publisher","DOI":"10.1046\/j.1469-7580.1998.19340481.x"},{"key":"e_1_3_2_6_2","doi-asserted-by":"publisher","DOI":"10.1177\/0363546518765158"},{"key":"e_1_3_2_7_2","doi-asserted-by":"publisher","DOI":"10.2519\/jospt.2007.2449"},{"key":"e_1_3_2_8_2","doi-asserted-by":"publisher","DOI":"10.1177\/03635465020300011701"},{"key":"e_1_3_2_9_2","doi-asserted-by":"publisher","DOI":"10.1097\/00003086-198702000-00019"},{"key":"e_1_3_2_10_2","doi-asserted-by":"publisher","DOI":"10.2106\/00004623-199072090-00009"},{"key":"e_1_3_2_11_2","doi-asserted-by":"publisher","DOI":"10.1177\/0363546510370291"},{"key":"e_1_3_2_12_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.jse.2020.01.074"},{"key":"e_1_3_2_13_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.jse.2019.01.012"},{"key":"e_1_3_2_14_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.arthro.2003.10.024"},{"key":"e_1_3_2_15_2","doi-asserted-by":"publisher","DOI":"10.1002\/jor.1100180117"},{"key":"e_1_3_2_16_2","doi-asserted-by":"publisher","DOI":"10.1177\/0363546512436801"},{"issue":"9","key":"e_1_3_2_17_2","article-title":"Clinico-radiological correlation of subcoracoid impingement with reduced coracohumeral interval and its relation to subscapularis tears in Indian patients","volume":"10","author":"Nair AV","year":"2016","unstructured":"Nair AV, Rao SN, Kumaran CK, Kochukunju BV.
