Magnetic resonance imaging described a superficial muscle belly in the distal forearm, compatible with a reversed palmaris longus (RPL). An initial trial of conservative treatment was unsuccessful, so the median nerve was explored in the distal forearm, with the release of the flexor retinaculum and resection of the RPL muscle belly. One year after surgery, the child had no symptoms.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion:<\/jats:title>\n                    <jats:p>To the best of our knowledge, there are only 12 reported cases of RPL, and none at such a young age or symptomatic in daily routine activities such as the case presented.<\/jats:p>\n                  <\/jats:sec>","DOI":"10.2106\/jbjs.cc.22.00386","type":"journal-article","created":{"date-parts":[[2023,2,23]],"date-time":"2023-02-23T10:08:18Z","timestamp":1677146898000},"update-policy":"https:\/\/doi.org\/10.1097\/lww.0000000000001000","source":"Crossref","is-referenced-by-count":1,"title":["Median Nerve Compression in the Distal Forearm by a Reversed Palmaris Longus Muscle in a Pediatric Patient"],"prefix":"10.2106","volume":"12","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-6980-8882","authenticated-orcid":false,"given":"Fl\u00e1via Pinto","family":"Moreira","sequence":"first","affiliation":[{"name":"Orthopedic Department of Centro Hospitalar e Universit\u00e1rio de S\u00e3o Jo\u00e3o, Porto, Portugal"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Filomena","family":"Ferreira","sequence":"additional","affiliation":[{"name":"Orthopedic Department of Unidade Local de Sa\u00fade do Alto Minho, Viana do Castelo, Portugal"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-7510-7572","authenticated-orcid":false,"given":"Luis","family":"Vieira","sequence":"additional","affiliation":[{"name":"Orthopedic Department of Centro Hospitalar e Universit\u00e1rio de S\u00e3o Jo\u00e3o, Porto, Portugal"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-4962-0302","authenticated-orcid":false,"given":"Pedro","family":"Negr\u00e3o","sequence":"additional","affiliation":[{"name":"Hospital CUF Porto, Porto, Portugal"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"276","published-online":{"date-parts":[[2022,10]]},"reference":[{"issue":"3","key":"bib1-20240805","doi-asserted-by":"crossref","first-page":"289","DOI":"10.1007\/s00276-019-02363-z","article-title":"Bilateral reversed palmaris longus muscle: a case report and systematic literature review","volume":"42","author":"Longhurst","year":"2020","journal-title":"Surg Radiol Anat."},{"issue":"2","key":"bib2-20240805","first-page":"215","article-title":"The palmaris longus muscle: its anatomic variations and functional morphology","volume":"49","author":"PAi","year":"2008","journal-title":"Rom J Morphol Embryol."},{"issue":"3","key":"bib3-20240805","doi-asserted-by":"crossref","first-page":"289","DOI":"10.1515\/folmed-2017-0035","article-title":"Palmaris longus muscle variations: clinical significance and proposal of new classifications","volume":"59","author":"Georgiev","year":"2017","journal-title":"Folia Med (Plovdiv)."},{"issue":"3","key":"bib4-20240805","first-page":"3","article-title":"A case of reverse palmaris longus muscle\u2014an additional muscle in the anterior compartment of the forearm","volume":"10","author":"Marpalli","year":"2016","journal-title":"J Clin Diagn Res."},{"issue":"1","key":"bib5-20240805","doi-asserted-by":"crossref","first-page":"55","DOI":"10.1177\/229255031302100115","article-title":"Reversed palmaris longus muscle: anatomical variant\u2014case report and literature review","volume":"21","author":"Murabit","year":"2013","journal-title":"Can J Plast Surg."},{"issue":"1","key":"bib6-20240805","doi-asserted-by":"crossref","first-page":"37","DOI":"10.1007\/s00381-018-3975-7","article-title":"Peripheral nerve injuries in the pediatric population: a review of the literature.
