The radial head, which abuts the extensor tendons and is elliptical in shape, may affect the extensor tendons during pronation of the forearm. Cadaverous studies have shown that the radial head may act as a cam in pronation, to offer a mechanical advantage to the common extensor tendon and to mitigate load on the origin of the extensor carpi radialis brevis tendon.<\/jats:p><\/jats:sec><jats:sec sec-type=\"objective\"><jats:title>Objective:<\/jats:title><jats:p>To determine the effect of radial-head position on the wrist-extensor tendons in vivo.<\/jats:p><\/jats:sec><jats:sec sec-type=\"design\"><jats:title>Design:<\/jats:title><jats:p>Repeated-measures design.<\/jats:p><\/jats:sec><jats:sec sec-type=\"setting\"><jats:title>Setting:<\/jats:title><jats:p>Laboratory.<\/jats:p><\/jats:sec><jats:sec sec-type=\"participants\"><jats:title>Participants:<\/jats:title><jats:p>22 participants (12 male, 2 left-handed).<\/jats:p><\/jats:sec><jats:sec sec-type=\"main outcome measures\"><jats:title>Main Outcome Measures:<\/jats:title><jats:p>Distance (mm) from subcutaneous fascia to radial head measured by ultrasound.<\/jats:p><\/jats:sec><jats:sec sec-type=\"results\"><jats:title>Results:<\/jats:title><jats:p>The radial head in supination was significantly deeper than either pronation or midprone, indicating a smaller cam effect in supination.<\/jats:p><\/jats:sec><jats:sec sec-type=\"conclusion\"><jats:title>Conclusion:<\/jats:title><jats:p>The authors recommend that the effect of radial-head position and its relationship to the area of tendon pathology be considered clinically in the rehabilitation of patients suffering from lateral epicondylalgia.<\/jats:p><\/jats:sec>","DOI":"10.1123\/jsr.2013-0073","type":"journal-article","created":{"date-parts":[[2014,6,6]],"date-time":"2014-06-06T18:24:00Z","timestamp":1402079040000},"page":"1-5","source":"Crossref","is-referenced-by-count":6,"title":["Forearm Position\u2019s Alteration of Radial-Head Impingement on Wrist-Extensor Tendons"],"prefix":"10.1123","volume":"24","author":[{"given":"Tom A.","family":"Ranger","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Wendy M.","family":"Braybon","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Craig R.","family":"Purdam","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jill L.","family":"Cook","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"100","container-title":["Journal of Sport Rehabilitation"],"original-title":[],"link":[{"URL":"https:\/\/journals.humankinetics.com\/view\/journals\/jsr\/24\/1\/article-p1.xml","content-type":"text\/html","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/journals.humankinetics.com\/downloadpdf\/journals\/jsr\/24\/1\/article-p1.xml","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2022,5,19]],"date-time":"2022-05-19T23:09:26Z","timestamp":1653001766000},"score":1,"resource":{"primary":{"URL":"https:\/\/journals.humankinetics.com\/view\/journals\/jsr\/24\/1\/article-p1.xml"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2015,2]]},"references-count":0,"journal-issue":{"issue":"1"},"URL":"https:\/\/doi.org\/10.1123\/jsr.2013-0073","relation":{},"ISSN":["1056-6716","1543-3072"],"issn-type":[{"value":"1056-6716","type":"print"},{"value":"1543-3072","type":"electronic"}],"subject":[],"published":{"date-parts":[[2015,2]]}}}
