We prospectively investigated the ultrasonographic history of these lesions to better understand the role of this lesion in AINP.\n                    <jats:italic>Methods<\/jats:italic>\n                    : Seven patients who were diagnosed with idiopathic AINP based on classic clinical findings and had hourglass\u2010like fascicular constrictions found on ultrasonography were included. All but 1 patient selected surgery, and we followed up all patients clinically and with ultrasonography.\n                    <jats:italic>Results<\/jats:italic>\n                    : In the 5 patients treated surgically in whom paralysis recovered to a level greater than M4, postoperative ultrasonography revealed less constriction. The other patient experienced little recovery after surgery, and the severe constriction remained. In a conservatively treated patient, the paralysis recovered completely, and upon ultrasonography, the constriction had lessened.\n                    <jats:italic>Conclusions<\/jats:italic>\n                    : Although the mechanism is still unknown, hourglass\u2010like fascicular constriction lessened with relief of motor weakness both in operatively and conservatively treated patients.\n                    <jats:italic>Muscle Nerve<\/jats:italic>\n                    <jats:bold>55<\/jats:bold>\n                    : 508\u2013512, 2017\n                  <\/jats:p>","DOI":"10.1002\/mus.25361","type":"journal-article","created":{"date-parts":[[2016,8,4]],"date-time":"2016-08-04T18:47:15Z","timestamp":1470336435000},"page":"508-512","source":"Crossref","is-referenced-by-count":23,"title":["Correlation between \u201chourglass\u2010like fascicular constriction\u201d and idiopathic anterior interosseous nerve palsy"],"prefix":"10.1002","volume":"55","author":[{"given":"Toru","family":"Sunagawa","sequence":"first","affiliation":[{"name":"Department of Orthopedic Surgery Hiroshima University Hospital 1\u20102\u20103 Kasumi Hiroshima 734\u20108551 Japan"},{"name":"Laboratory of Analysis and Control of Upper Extremity Function Institute of Biomedical and Health Sciences, Hiroshima University Hiroshima Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yuko","family":"Nakashima","sequence":"additional","affiliation":[{"name":"Department of Orthopedic Surgery Hiroshima University Hospital 1\u20102\u20103 Kasumi Hiroshima 734\u20108551 Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Rikuo","family":"Shinomiya","sequence":"additional","affiliation":[{"name":"Department of Orthopedic Surgery Hiroshima University Hospital 1\u20102\u20103 Kasumi Hiroshima 734\u20108551 Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Hiroshi","family":"Kurumadani","sequence":"additional","affiliation":[{"name":"Laboratory of Analysis and Control of Upper Extremity Function Institute of Biomedical and Health Sciences, Hiroshima University Hiroshima Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Nobuo","family":"Adachi","sequence":"additional","affiliation":[{"name":"Department of Orthopedic Surgery Hiroshima University Hospital 1\u20102\u20103 Kasumi Hiroshima 734\u20108551 Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Mitsuo","family":"Ochi","sequence":"additional","affiliation":[{"name":"Department of Orthopedic Surgery Hiroshima University Hospital 1\u20102\u20103 Kasumi Hiroshima 734\u20108551 Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2016,12,23]]},"reference":[{"key":"e_1_2_6_2_1","doi-asserted-by":"publisher","DOI":"10.1016\/S0266-7681(97)80020-4"},{"key":"e_1_2_6_3_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.jhsa.2009.10.017"},{"key":"e_1_2_6_4_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.jhsa.2010.08.018"},{"key":"e_1_2_6_5_1","doi-asserted-by":"publisher","DOI":"10.1016\/S0266-7681(00)80013-3"},{"key":"e_1_2_6_6_1","doi-asserted-by":"publisher","DOI":"10.1093\/brain\/awh722"},{"key":"e_1_2_6_7_1","doi-asserted-by":"publisher","DOI":"10.1016\/S0363-5023(96)80114-6"},{"key":"e_1_2_6_8_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.jhsa.2011.03.041"},{"key":"e_1_2_6_9_1","doi-asserted-by":"publisher","DOI":"10.7863\/jum.2004.23.7.1003"},{"key":"e_1_2_6_10_1","doi-asserted-by":"publisher","DOI":"10.7863\/jum.2007.26.5.683"},{"key":"e_1_2_6_11_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.ultrasmedbio.2013.12.011"},{"key":"e_1_2_6_12_1","doi-asserted-by":"publisher","DOI":"10.1227\/NEU.0000000000000350"},{"key":"e_1_2_6_13_1","doi-asserted-by":"publisher","DOI":"10.1002\/mus.24615"},{"key":"e_1_2_6_14_1","doi-asserted-by":"publisher","DOI":"10.1053\/jhsu.2003.50040"},{"key":"e_1_2_6_15_1","doi-asserted-by":"crossref","first-page":"642","DOI":"10.1177\/1753193413518692","article-title":"Early treatment of anterior interosseous nerve palsy with hourglass\u2010like fascicular constrictions by interfascicular neurolysis due to early diagnosis using ultrasonography: A case report","volume":"40","author":"Kodama A","journal-title":"J Hand Surg Eur"},{"key":"e_1_2_6_16_1","doi-asserted-by":"publisher","DOI":"10.3109\/2000656X.2011.634558"},{"key":"e_1_2_6_17_1","doi-asserted-by":"publisher","DOI":"10.1227\/NEU.0000000000000424"}],"container-title":["Muscle &amp;
