Preoperative magnetic resonance imaging (MRI) assessed the presence of subclavius posticus muscle (SPM). Because of a nonoperative treatment failure, we performed a brachial plexus neurolysis and SPM resection. Immediate postoperative assessment showed an immediate disappearance of the Wartenberg sign.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion:<\/jats:title>\n                    <jats:p>SPM constitutes an underestimated cause of TOS. A careful MRI reading is necessary to make correct diagnosis. Nonoperative treatment includes physiotherapy and can be proposed in first instance. When nonoperative treatment fails, brachial plexus exploration with release of the SPM may result in resolution of symptoms.<\/jats:p>\n                  <\/jats:sec>","DOI":"10.2106\/jbjs.cc.20.00668","type":"journal-article","created":{"date-parts":[[2021,11,12]],"date-time":"2021-11-12T12:00:05Z","timestamp":1636718405000},"update-policy":"https:\/\/doi.org\/10.1097\/lww.0000000000001000","source":"Crossref","is-referenced-by-count":3,"title":["Rare Case of Dynamic Thoracic Outlet Syndrome Resolved by an Isolated Subclavius Posticus Muscle Resection"],"prefix":"10.2106","volume":"11","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-5589-3673","authenticated-orcid":false,"given":"Ruben","family":"Dukan","sequence":"first","affiliation":[{"name":"Hand, Upper Limb, and Peripheral Nerve Surgery Service, Georges-Pompidou European Hospital (HEGP), Paris, France"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-9490-6975","authenticated-orcid":false,"given":"Gautier","family":"Petroni","sequence":"additional","affiliation":[{"name":"Hand, Upper Limb, and Peripheral Nerve Surgery Service, Georges-Pompidou European Hospital (HEGP), Paris, France"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-5709-3314","authenticated-orcid":false,"given":"Guy-Paul","family":"Muller","sequence":"additional","affiliation":[{"name":"Polyclinique de Paofai, Papeete, French Polynesia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jonathan","family":"Silvera","sequence":"additional","affiliation":[{"name":"Clinique Blomet (Research Unit), Paris, France"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-9840-9802","authenticated-orcid":false,"given":"Emmanuel H.","family":"Masmejean","sequence":"additional","affiliation":[{"name":"Hand, Upper Limb, and Peripheral Nerve Surgery Service, Georges-Pompidou European Hospital (HEGP), Paris, France"},{"name":"Clinique Blomet (Research Unit), Paris, France"},{"name":"University of Paris\u2014Medical School, Paris, France"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"276","published-online":{"date-parts":[[2021,7]]},"reference":[{"key":"bib1-20240731","doi-asserted-by":"crossref","first-page":"222","DOI":"10.5435\/JAAOS-D-13-00215","article-title":"Thoracic outlet syndrome","volume":"23","author":"Kuhn","year":"2015","journal-title":"J Am Acad Orthop Surg."},{"key":"bib2-20240731","doi-asserted-by":"crossref","first-page":"74","DOI":"10.1179\/106698110X12640740712734","article-title":"Thoracic outlet syndrome: a controversial clinical condition.
