The case was a 40-year-old male heavy manual worker complaining of numbness and pain in the median nerve area. On active flexion of the fingers, snapping was observed at the carpal area, and forceful full grip was impossible. Tinel\u2019s sign was positive and an electromyographic study revealed conduction disturbance of the median nerve at the carpal tunnel. Magnetic resonance imaging revealed edematous lumbrical muscle with synovial proliferation around the flexor tendons. Open carpal tunnel release was performed under local anesthesia. Synovial proliferation of the flexor tendons was found and when flexing the index and middle fingers, the lumbrical muscle was drawn into the carpal tunnel with a triggering phenomenon. After releasing the carpal tunnel, the triggering phenomenon and painful numbness improved.<\/jats:p>","DOI":"10.1155\/2015\/705237","type":"journal-article","created":{"date-parts":[[2015,6,11]],"date-time":"2015-06-11T10:19:49Z","timestamp":1434017989000},"page":"1-3","source":"Crossref","is-referenced-by-count":6,"title":["Carpal Tunnel Syndrome with Wrist Trigger Caused by Hypertrophied Lumbrical Muscle and Tenosynovitis"],"prefix":"10.1155","volume":"2015","author":[{"given":"Ayuko","family":"Shimizu","sequence":"first","affiliation":[{"name":"Department of Orthopaedics, Tokai University School of Medicine, 143 Shimokasuya, Isehara, Kanagawa 259-0198, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Masayoshi","family":"Ikeda","sequence":"additional","affiliation":[{"name":"Department of Orthopaedics, Tokai University School of Medicine, 143 Shimokasuya, Isehara, Kanagawa 259-0198, Japan"},{"name":"Department of Orthopaedic Surgery, Shonan Central Hospital, 1-3-43 Hatori, Fujisawa, Kanagawa 251-0056, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Yuka","family":"Kobayashi","sequence":"additional","affiliation":[{"name":"Department of Orthopaedics, Tokai University School of Medicine, 143 Shimokasuya, Isehara, Kanagawa 259-0198, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Ikuo","family":"Saito","sequence":"additional","affiliation":[{"name":"Department of Orthopaedics, Tokai University School of Medicine, 143 Shimokasuya, Isehara, Kanagawa 259-0198, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Joji","family":"Mochida","sequence":"additional","affiliation":[{"name":"Department of Orthopaedics, Tokai University School of Medicine, 143 Shimokasuya, Isehara, Kanagawa 259-0198, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"98","reference":[{"key":"1","doi-asserted-by":"publisher","DOI":"10.1001\/jama.282.2.153"},{"key":"2","first-page":"977","volume-title":"Compression neuropathies","volume":"1","year":"2011"},{"key":"3","doi-asserted-by":"publisher","DOI":"10.1002\/(sici)1097-4598(199712)20:12lt;1477::aid-mus1>3.0.co;2-5"},{"issue":"1","key":"4","doi-asserted-by":"crossref","first-page":"82","DOI":"10.1016\/S0363-5023(78)80120-8","volume":"3","year":"1978","journal-title":"The Journal of Hand Surgery\u2014American Volume"},{"key":"5","doi-asserted-by":"publisher","DOI":"10.1016\/s0363-5023(05)80005-x"},{"key":"6","doi-asserted-by":"publisher","DOI":"10.1016\/S0363-5023(05)80444-7"},{"issue":"4","key":"7","doi-asserted-by":"crossref","first-page":"517","DOI":"10.1002\/mus.24183","volume":"50","year":"2014","journal-title":"Muscle & Nerve"},{"key":"8","doi-asserted-by":"publisher","DOI":"10.3109\/02844317009038447"},{"issue":"2","key":"9","first-page":"72","volume":"25","year":"1993","journal-title":"Handchirurgie Mikrochirurgie Plastische Chirurgie"},{"issue":"1","key":"10","doi-asserted-by":"crossref","first-page":"85","DOI":"10.3928\/0147-7447-20030101-21","volume":"26","year":"2003","journal-title":"Orthopedics"},{"key":"11","doi-asserted-by":"publisher","DOI":"10.3109\/02844318909004509"},{"issue":"6","key":"12","first-page":"302","volume":"21","year":"1989","journal-title":"Handchirurgie Mikrochirurgie Plastische Chirugie"},{"issue":"2","key":"13","doi-asserted-by":"crossref","first-page":"205","DOI":"10.1142\/S0218810412500207","volume":"17","year":"2012","journal-title":"Hand Surgery"}],"container-title":["Case Reports in Orthopedics"],"original-title":[],"language":"en","link":[{"URL":"http:\/\/downloads.hindawi.com\/journals\/crior\/2015\/705237.pdf","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"http:\/\/downloads.hindawi.com\/journals\/crior\/2015\/705237.xml","content-type":"application\/xml","content-version":"vor","intended-application":"text-mining"},{"URL":"http:\/\/downloads.hindawi.com\/journals\/crior\/2015\/705237.pdf","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2022,5,12]],"date-time":"2022-05-12T14:41:08Z","timestamp":1652366468000},"score":1,"resource":{"primary":{"URL":"http:\/\/www.hindawi.com\/journals\/crior\/2015\/705237\/"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2015]]},"references-count":13,"alternative-id":["705237","705237"],"URL":"https:\/\/doi.org\/10.1155\/2015\/705237","relation":{},"ISSN":["2090-6749","2090-6757"],"issn-type":[{"value":"2090-6749","type":"print"},{"value":"2090-6757","type":"electronic"}],"subject":[],"published":{"date-parts":[[2015]]}}}
