While conservative treatments are effective in infants, surgical intervention is necessary for older who experience deformities or functional impairments. We report an adolescent patient with an untreated clasped thumb who underwent extensor pollicis brevis (EPB) reconstruction using the extensor indicis proprius (EIP) tendon through the first dorsal compartment. The patient suffered from a right thumb deformity and pain. EPB reconstruction was performed by passing the EIP tendon through the first dorsal compartment. After 1 year and 6\u2009months of follow-up, the patient\u2019s right thumb function significantly improved, with an increased range of motion and strength of the thumb, and the preoperative pain was relieved. EPB reconstruction using EIP passing through the first dorsal compartment for clasped thumbs in adolescents can reconstruct the EPB function appropriately and is a possible treatment option.<\/jats:p>","DOI":"10.1136\/bcr-2024-263009","type":"journal-article","created":{"date-parts":[[2024,12,15]],"date-time":"2024-12-15T20:35:26Z","timestamp":1734294926000},"page":"e263009","update-policy":"https:\/\/doi.org\/10.1136\/crossmarkpolicy","source":"Crossref","is-referenced-by-count":0,"title":["Extensor pollicis brevis reconstruction using the extensor digitorum proprius tendon through the first dorsal compartment for a clasped thumb in an adolescent"],"prefix":"10.1136","volume":"17","author":[{"given":"Hiroaki","family":"Takeya","sequence":"first","affiliation":[{"name":"Division of Orthopaedic Surgery, Department of Surgical Specialties, National Center for Child Health and Development, Setagaya-ku, Tokyo, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-5011-6015","authenticated-orcid":false,"given":"Takehiko","family":"Takagi","sequence":"additional","affiliation":[{"name":"Division of Orthopaedic Surgery, Department of Surgical Specialties, National Center for Child Health and Development, Setagaya-ku, Tokyo, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"239","published-online":{"date-parts":[[2024,12,15]]},"reference":[{"key":"2025082722202656000_17.12.e263009.1","first-page":"1417","article-title":"Congenital Clasped Thumb (Congenital Flexion-Adduction Deformity of the Thumb)","volume":"50","author":"Weckesser","year":"1968","journal-title":"The Journal of Bone & Joint Surgery"},{"key":"2025082722202656000_17.12.e263009.2","doi-asserted-by":"publisher","DOI":"10.1016\/S0363-5023(85)80193-3"},{"key":"2025082722202656000_17.12.e263009.3","doi-asserted-by":"crossref","first-page":"313","DOI":"10.1007\/s11832-007-0057-x","article-title":"Characteristics of patients with congenital clasped thumb: A prospective study of 40 patients with the results of treatment","volume":"1","author":"Hisham Abdel","year":"2007","journal-title":"J Child Orthop"},{"key":"2025082722202656000_17.12.e263009.4","unstructured":"Scott HK .
