The joint is locked in mild hyperextension and cannot flex actively or passively. We report four patients with locked MCP joint of the thumb due to radial sesamoid entrapment after hyperextension or forced flexion injury. All patients had a prominent radial condyle of the metacarpal bone. Three patients had a deformity of the longitudinal groove on which the sesamoid was overlaid. The radial sesamoid was entrapped proximal to the radial condyle which could result in limited extension and hinged flexion of the joint. Excision of the radial sesamoid could release the locked joint. The radial sesamoid should be assessed if the motion of the thumb MCP joint is limited after flexion or extension injury. <\/jats:p><jats:p> Level of Evidence: Level V (Therapeutic) <\/jats:p>","DOI":"10.1142\/s2424835522720274","type":"journal-article","created":{"date-parts":[[2022,7,9]],"date-time":"2022-07-09T06:40:18Z","timestamp":1657348818000},"page":"580-585","source":"Crossref","is-referenced-by-count":3,"title":["Locking of the Metacarpophalangeal Joint of the Thumb Caused by Entrapment of the Radial Sesamoid Bone"],"prefix":"10.1142","volume":"27","author":[{"given":"Sanglim","family":"LEE","sequence":"first","affiliation":[{"name":"Department of Orthopedic Surgery, Inje University Sanggye Paik Hospital, Seoul, South Korea"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Suk Ha","family":"JEON","sequence":"additional","affiliation":[{"name":"Department of Orthopaedic Surgery, National Medical Center, Seoul, South Korea"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"219","published-online":{"date-parts":[[2022,6,13]]},"reference":[{"key":"S2424835522720274BIB001","doi-asserted-by":"publisher","DOI":"10.1016\/J.JHSB.2006.07.010"},{"key":"S2424835522720274BIB002","doi-asserted-by":"publisher","DOI":"10.1097\/SAP.0000000000001702"},{"issue":"4","key":"S2424835522720274BIB003","first-page":"469","volume":"13","author":"Inoue G","year":"1988","journal-title":"J Hand Surg Br"},{"key":"S2424835522720274BIB004","doi-asserted-by":"publisher","DOI":"10.1016\/0266-7681(94)90090-6"},{"key":"S2424835522720274BIB005","doi-asserted-by":"publisher","DOI":"10.1016\/S0363-5023(10)80068-1"},{"key":"S2424835522720274BIB006","doi-asserted-by":"publisher","DOI":"10.1016\/0072-968X(74)90036-9"},{"key":"S2424835522720274BIB007","doi-asserted-by":"publisher","DOI":"10.1177\/229255031101900406"},{"key":"S2424835522720274BIB008","first-page":"2136540","volume":"2019","author":"Carroll JJ","year":"2019","journal-title":"Case Rep Orthop"},{"key":"S2424835522720274BIB009","doi-asserted-by":"publisher","DOI":"10.1177\/1753193413517621"}],"container-title":["The Journal of Hand Surgery (Asian-Pacific Volume)"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/www.worldscientific.com\/doi\/pdf\/10.1142\/S2424835522720274","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2022,10,10]],"date-time":"2022-10-10T03:49:53Z","timestamp":1665373793000},"score":1,"resource":{"primary":{"URL":"https:\/\/www.worldscientific.com\/doi\/10.1142\/S2424835522720274"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2022,6]]},"references-count":9,"journal-issue":{"issue":"03","published-print":{"date-parts":[[2022,6]]}},"alternative-id":["10.1142\/S2424835522720274"],"URL":"https:\/\/doi.org\/10.1142\/s2424835522720274","relation":{},"ISSN":["2424-8355","2424-8363"],"issn-type":[{"value":"2424-8355","type":"print"},{"value":"2424-8363","type":"electronic"}],"subject":[],"published":{"date-parts":[[2022,6]]}}}
