We categorized these injections into two groups based on the occurrence of intra-epineurial injection. We also recorded clinical data including sex, age, side of injection, BMI, and the duration of pre-injection CTS-related discomfort. The outcomes were measured using the Likert satisfaction scale and Boston Carpal Tunnel Questionnaire (BCTQ) scores. The clinical data, cross-sectional area of the median nerve (CSA-MN) at the inlet of the carpal tunnel measured on\u00a0US images, and the symptom relief for the patients receiving intra-epineurial and extra-epineurial injection were compared.<\/jats:p><jats:p>\n          Results\u2002The intra-epineurial injection rate was 38.6\u200a% in the 101 US-guided injections. The clinical data, pre-injection CSA-MN at the inlet of the carpal tunnel, and pre-injection BCTQ scores showed no significant intergroup differences (p\u200a&gt;\u200a0.05). The group with intra-epineurial injections had significantly decreased CSA-MN (difference in means, 2.5\u200amm2; p\u200a&lt;\u200a0.0001), greater patient satisfaction (p\u200a=\u200a0.002), and lower BCTQ scores (p\u200a&lt;\u200a0.05) than the group with extra-epineurial injections.<\/jats:p><jats:p>\n          Conclusion\u2002We characterized the US findings of intra-epineurial corticosteroid injection during US-guided hydrodissection. Intra-epineurial injection provided a more meaningfully reduction in edema of the MN, greater patient satisfaction, and greater symptom relief than extra-epineurial injection.<\/jats:p>","DOI":"10.1055\/s-0043-120109","type":"journal-article","created":{"date-parts":[[2017,12,28]],"date-time":"2017-12-28T18:33:58Z","timestamp":1514486038000},"page":"334-342","source":"Crossref","is-referenced-by-count":11,"title":["Ultrasound-Guided Corticosteroid Injection in Patients with Carpal Tunnel Syndrome: Efficacy of Intra-Epineurial Injection"],"prefix":"10.1055","volume":"39","author":[{"given":"Yi-Chih","family":"Hsu","sequence":"additional","affiliation":[{"name":"Radiology,  Tri-Service General Hospital, National Defense Medical Center, Taipei, Taiwan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Fu-Chi","family":"Yang","sequence":"additional","affiliation":[{"name":"Neurology, Tri-Service General Hospital, National Defense Medical Center, Taipei, Taiwan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Hsian-He","family":"Hsu","sequence":"additional","affiliation":[{"name":"Radiology,  Tri-Service General Hospital, National Defense Medical Center, Taipei, Taiwan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Guo-Shu","family":"Huang","sequence":"additional","affiliation":[{"name":"Radiology,  Tri-Service General Hospital, National Defense Medical Center, Taipei, Taiwan"},{"name":"Medical Research, Tri-Service General Hospital, National Defense Medical Center, Taipei, Taiwan"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"194","published-online":{"date-parts":[[2017,12,28]]},"container-title":["Ultraschall in der Medizin - European Journal of Ultrasound"],"original-title":[],"language":"de","link":[{"URL":"http:\/\/www.thieme-connect.de\/products\/ejournals\/pdf\/10.1055\/s-0043-120109.pdf","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2018,6,7]],"date-time":"2018-06-07T19:12:51Z","timestamp":1528398771000},"score":1,"resource":{"primary":{"URL":"http:\/\/www.thieme-connect.de\/DOI\/DOI?10.1055\/s-0043-120109"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2017,12,28]]},"references-count":0,"journal-issue":{"issue":"03","published-online":{"date-parts":[[2018,4,24]]},"published-print":{"date-parts":[[2018,6]]}},"URL":"https:\/\/doi.org\/10.1055\/s-0043-120109","relation":{},"ISSN":["0172-4614","1438-8782"],"issn-type":[{"value":"0172-4614","type":"print"},{"value":"1438-8782","type":"electronic"}],"subject":[],"published":{"date-parts":[[2017,12,28]]}}}
