We measured the dorsal-palmar (DP) diameter, radioulnar (RU) diameter and cross-sectional area (CSA) of the flexor pollicis longus (FPL) tendon at two sites: just proximal to the A1 pulley and underneath the A1 pulley using ultrasonography. Following surgical A1 pulley release, the DP diameter, RU diameter and CSA of the FPL tendon just proximal to the A1 pulley significantly decreased from 2.6\u2009mm to 2.2\u2009mm, from 5.1\u2009mm to 4.2\u2009mm and from 11\u2009mm\n                    <jats:sup>2<\/jats:sup>\n                    to 7.8\u2009mm\n                    <jats:sup>2<\/jats:sup>\n                    , respectively. Additionally, the RU diameter and CSA of the FPL tendon at the area beneath the A1 pulley significantly increased from 2.2\u2009mm to 3.2\u2009mm and from 4.3\u2009mm\n                    <jats:sup>2<\/jats:sup>\n                    to 5.8\u2009mm\n                    <jats:sup>2<\/jats:sup>\n                    , respectively. This finding suggests that the conformation of the FPL tendon of the affected thumb tends to return to that of the contralateral uninvolved thumb after A1 pulley release. Underdevelopment of the inner space around the A1 pulley may contribute to the development of paediatric trigger thumb.\n                  <\/jats:p>\n                  <jats:p>Level of evidence: III<\/jats:p>","DOI":"10.1177\/17531934231191257","type":"journal-article","created":{"date-parts":[[2023,9,26]],"date-time":"2023-09-26T14:03:25Z","timestamp":1695737005000},"page":"1136-1143","update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":2,"title":["Changes in flexor pollicis longus tendon cross-sectional dimensions after A1 pulley release for paediatric trigger thumb"],"prefix":"10.1177","volume":"48","author":[{"given":"Cha Hyeong","family":"Ok","sequence":"first","affiliation":[{"name":"Department of Orthopedic Surgery, Asan Medical Center, University of Ulsan College of Medicine, Seoul, South Korea"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Young Ho","family":"Shin","sequence":"additional","affiliation":[{"name":"Department of Orthopedic Surgery, Asan Medical Center, University of Ulsan College of Medicine, Seoul, South Korea"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Ho Yeon","family":"Kim","sequence":"additional","affiliation":[{"name":"Department of Orthopedic Surgery, Asan Medical Center, University of Ulsan College of Medicine, Seoul, South Korea"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-5104-4634","authenticated-orcid":false,"given":"Jae Kwang","family":"Kim","sequence":"additional","affiliation":[{"name":"Department of Orthopedic Surgery, Asan Medical Center, University of Ulsan College of Medicine, Seoul, South Korea"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"179","published-online":{"date-parts":[[2023,9,26]]},"reference":[{"key":"bibr1-17531934231191257","doi-asserted-by":"publisher","DOI":"10.1097\/01241398-199905000-00024"},{"key":"bibr2-17531934231191257","doi-asserted-by":"publisher","DOI":"10.1097\/BPO.0000000000001486"},{"key":"bibr3-17531934231191257","doi-asserted-by":"publisher","DOI":"10.1097\/BPB.0b013e3283536962"},{"key":"bibr4-17531934231191257","doi-asserted-by":"publisher","DOI":"10.1016\/j.jhsa.2005.12.024"},{"key":"bibr5-17531934231191257","doi-asserted-by":"publisher","DOI":"10.1016\/j.jhsa.2017.08.011"},{"key":"bibr6-17531934231191257","doi-asserted-by":"publisher","DOI":"10.1016\/j.jcm.2016.02.012"},{"key":"bibr7-17531934231191257","doi-asserted-by":"publisher","DOI":"10.1007\/s00330-020-07048-5"},{"key":"bibr8-17531934231191257","doi-asserted-by":"publisher","DOI":"10.1054\/jhsb.2000.0417"},{"key":"bibr9-17531934231191257","doi-asserted-by":"publisher","DOI":"10.1016\/0363-5023(94)90046-9"},{"key":"bibr10-17531934231191257","doi-asserted-by":"publisher","DOI":"10.5435\/JAAOS-20-04-206"},{"key":"bibr11-17531934231191257","doi-asserted-by":"publisher","DOI":"10.1016\/j.hansur.2022.05.009"},{"key":"bibr12-17531934231191257","doi-asserted-by":"publisher","DOI":"10.1177\/1753193416641590"},{"key":"bibr13-17531934231191257","doi-asserted-by":"publisher","DOI":"10.1097\/BPO.0b013e318287f728"}],"container-title":["Journal of Hand Surgery (European Volume)"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/journals.sagepub.com\/doi\/pdf\/10.1177\/17531934231191257","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/journals.sagepub.com\/doi\/full-xml\/10.1177\/17531934231191257","content-type":"application\/xml","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/journals.sagepub.com\/doi\/pdf\/10.1177\/17531934231191257","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2026,4,29]],"date-time":"2026-04-29T22:46:44Z","timestamp":1777502804000},"score":1,"resource":{"primary":{"URL":"https:\/\/journals.sagepub.com\/doi\/10.1177\/17531934231191257"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2023,9,26]]},"references-count":13,"journal-issue":{"issue":"11","published-print":{"date-parts":[[2023,12]]}},"alternative-id":["10.1177\/17531934231191257"],"URL":"https:\/\/doi.org\/10.1177\/17531934231191257","relation":{},"ISSN":["1753-1934","2043-6289"],"issn-type":[{"value":"1753-1934","type":"print"},{"value":"2043-6289","type":"electronic"}],"subject":[],"published":{"date-parts":[[2023,9,26]]}}}
