Few studies, showing contradictory results, exist investigating ultrasound results as a predictor of patient outcomes. Methods: Patients with ultrasound measurement of the cross-sectional area (CSA) of the median nerve who completed the Boston Carpal Tunnel Questionnaire (BCTQ) and followed up after surgery were included in the study. A total of 199 wrists from 172 patients met the inclusion criteria. Preoperative CSA of the median nerve at the wrist was compared with change in BCTQ at various follow-up times postoperatively. Results: The BCTQ score was found on average to decrease for patients after surgery at all 3 follow-up times. There was a larger decrease in the preoperative BCTQ with each progressive follow-up time, with the largest change of 1.43 points coming at 6+ months. The average change in BCTQ at each follow-up time was found to be greater than the minimal clinically important difference. The greatest R\n                    <jats:sup>2<\/jats:sup>\n                    for preoperative CSA compared with change in BCTQ was 0.0552 for the 6+ month visits. No specific CSA value or range above or below which patients have better postoperative outcomes was found. Conclusions: Higher preoperative CSA, signifying worse carpal tunnel severity, showed almost no correlation with better outcomes after carpal tunnel release surgery as measured by improvement in patient-reported outcome scores.\n                  <\/jats:p>","DOI":"10.1177\/1558944720919182","type":"journal-article","created":{"date-parts":[[2020,5,23]],"date-time":"2020-05-23T03:26:04Z","timestamp":1590204364000},"page":"219-223","update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":11,"title":["Prognostic Value of Ultrasound Imaging of the Median Nerve in Carpal Tunnel Syndrome"],"prefix":"10.1177","volume":"17","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-5066-0790","authenticated-orcid":false,"given":"Cory","family":"Demino","sequence":"first","affiliation":[{"name":"University of Pittsburgh, School of Medicine, PA, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"John R.","family":"Fowler","sequence":"additional","affiliation":[{"name":"University of Pittsburgh Medical Center, PA, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"179","published-online":{"date-parts":[[2020,5,23]]},"reference":[{"key":"bibr1-1558944720919182","doi-asserted-by":"publisher","DOI":"10.1002\/mus.22208"},{"key":"bibr2-1558944720919182","doi-asserted-by":"publisher","DOI":"10.1007\/s11999-010-1637-5"},{"key":"bibr3-1558944720919182","doi-asserted-by":"publisher","DOI":"10.1093\/rheumatology\/keu275"},{"key":"bibr4-1558944720919182","doi-asserted-by":"publisher","DOI":"10.5334\/jbsr.1354"},{"issue":"5","key":"bibr5-1558944720919182","first-page":"786","volume":"27","author":"Naranjo A","year":"2009","journal-title":"Clin Exp Rheumatol"},{"key":"bibr6-1558944720919182","doi-asserted-by":"publisher","DOI":"10.1002\/mus.20982"},{"key":"bibr7-1558944720919182","doi-asserted-by":"publisher","DOI":"10.1002\/mus.24058"},{"key":"bibr8-1558944720919182","doi-asserted-by":"publisher","DOI":"10.1053\/jhsu.2003.50043"},{"key":"bibr9-1558944720919182","doi-asserted-by":"publisher","DOI":"10.3109\/17453679809002363"},{"key":"bibr10-1558944720919182","doi-asserted-by":"publisher","DOI":"10.1186\/1471-2474-7-78"},{"key":"bibr11-1558944720919182","doi-asserted-by":"publisher","DOI":"10.1016\/j.jhsa.2015.07.010"}],"container-title":["HAND"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/journals.sagepub.com\/doi\/pdf\/10.1177\/1558944720919182","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/journals.sagepub.com\/doi\/full-xml\/10.1177\/1558944720919182","content-type":"application\/xml","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/journals.sagepub.com\/doi\/pdf\/10.1177\/1558944720919182","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2026,4,29]],"date-time":"2026-04-29T07:26:55Z","timestamp":1777447615000},"score":1,"resource":{"primary":{"URL":"https:\/\/journals.sagepub.com\/doi\/10.1177\/1558944720919182"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2020,5,23]]},"references-count":11,"journal-issue":{"issue":"2","published-print":{"date-parts":[[2022,3]]}},"alternative-id":["10.1177\/1558944720919182"],"URL":"https:\/\/doi.org\/10.1177\/1558944720919182","relation":{},"ISSN":["1558-9447","1558-9455"],"issn-type":[{"value":"1558-9447","type":"print"},{"value":"1558-9455","type":"electronic"}],"subject":[],"published":{"date-parts":[[2020,5,23]]}}}
