Electrodiagnostic (EDx) studies may only identify the most proximal lesion. Nerve ultrasound could augment EDx by visualizing additional pathology. <jats:italic>Methods<\/jats:italic>: This investigation was a retrospective examination of ultrasound and EDx from 26 patients evaluated for posterior cord\/radial\/PIN lesions. <jats:italic>Results<\/jats:italic>: Eighteen of 26 patients had abnormalities on EDx (15 radial, 2 PIN, 1 posterior cord). Ultrasound identified 15 of 18 (83%) of the EDx abnormalities and provided additional diagnostic information. In 6 of 15 (40%) patients with EDx evidence of radial neuropathy, ultrasound identified both radial nerve enlargement and additional, unsuspected PIN enlargement (53% to 339% enlarged vs. unaffected side). Ultrasound also identified: nerve (dis)continuity at the trauma site (<jats:italic>n<\/jats:italic> = 8); and nerve tumor (<jats:italic>n<\/jats:italic> = 2; 1 with normal EDx). <jats:italic>Conclusion<\/jats:italic>: In radial neuropathy, ultrasound often augments EDx studies and identifies a second lesion in the PIN. Further studies are required to determine the etiology and significance of this additional distal pathology. <jats:italic>Muscle Nerve<\/jats:italic> 53: 379\u2013383, 2016<\/jats:p>","DOI":"10.1002\/mus.24778","type":"journal-article","created":{"date-parts":[[2015,7,22]],"date-time":"2015-07-22T22:41:15Z","timestamp":1437604875000},"page":"379-383","source":"Crossref","is-referenced-by-count":37,"title":["Nerve ultrasound identifies abnormalities in the posterior interosseous nerve in patients with proximal radial neuropathies"],"prefix":"10.1002","volume":"53","author":[{"given":"Alexander R.","family":"Dietz","sequence":"first","affiliation":[{"name":"Department of Neurology Washington University School of Medicine 660 South Euclid Avenue, Box 8111 St. Louis Missouri 63110 USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Robert C.","family":"Bucelli","sequence":"additional","affiliation":[{"name":"Department of Neurology Washington University School of Medicine 660 South Euclid Avenue, Box 8111 St. Louis Missouri 63110 USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Alan","family":"Pestronk","sequence":"additional","affiliation":[{"name":"Department of Neurology Washington University School of Medicine 660 South Euclid Avenue, Box 8111 St. Louis Missouri 63110 USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Craig M.","family":"Zaidman","sequence":"additional","affiliation":[{"name":"Department of Neurology Washington University School of Medicine 660 South Euclid Avenue, Box 8111 St. Louis Missouri 63110 USA"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2015,12,29]]},"reference":[{"key":"e_1_2_6_2_1","doi-asserted-by":"publisher","DOI":"10.1136\/jnnp.2005.066696"},{"key":"e_1_2_6_3_1","doi-asserted-by":"publisher","DOI":"10.2176\/nmc.44.14"},{"key":"e_1_2_6_4_1","doi-asserted-by":"publisher","DOI":"10.1177\/1753193409360283"},{"key":"e_1_2_6_5_1","doi-asserted-by":"publisher","DOI":"10.1002\/mus.21580"},{"key":"e_1_2_6_6_1","doi-asserted-by":"publisher","DOI":"10.1302\/0301-620X.87B3.15253"},{"key":"e_1_2_6_7_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.apmr.2011.05.007"},{"key":"e_1_2_6_8_1","doi-asserted-by":"publisher","DOI":"10.4103\/0019-5413.128774"},{"key":"e_1_2_6_9_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.clinph.2012.07.015"},{"key":"e_1_2_6_10_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.ultrasmedbio.2013.12.011"},{"key":"e_1_2_6_11_1","doi-asserted-by":"publisher","DOI":"10.1148\/radiology.219.3.r01jn09811"},{"key":"e_1_2_6_12_1","doi-asserted-by":"publisher","DOI":"10.14366\/usg.14060"},{"key":"e_1_2_6_13_1","doi-asserted-by":"publisher","DOI":"10.1097\/PHM.0b013e3181e29daa"},{"key":"e_1_2_6_14_1","doi-asserted-by":"publisher","DOI":"10.1002\/jcu.20067"},{"key":"e_1_2_6_15_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.clinph.2011.05.016"},{"key":"e_1_2_6_16_1","doi-asserted-by":"publisher","DOI":"10.1212\/WNL.0b013e3182904f3f"},{"key":"e_1_2_6_17_1","doi-asserted-by":"publisher","DOI":"10.1111\/j.1468-1331.2011.03421.x"},{"key":"e_1_2_6_18_1","doi-asserted-by":"publisher","DOI":"10.1055\/s-2004-818486"},{"key":"e_1_2_6_19_1","doi-asserted-by":"publisher","DOI":"10.1007\/s00330-010-1992-3"},{"key":"e_1_2_6_20_1","doi-asserted-by":"publisher","DOI":"10.1007\/s00415-013-7123-8"},{"key":"e_1_2_6_21_1","doi-asserted-by":"publisher","DOI":"10.1002\/mus.24227"},{"key":"e_1_2_6_22_1","doi-asserted-by":"publisher","DOI":"10.1212\/WNL.0000000000000128"},{"key":"e_1_2_6_23_1","first-page":"xvii","volume-title":"Electromyography and neuromuscular disorders: clinical\u2010electrophysiologic correlations","author":"Preston DC","year":"2013"},{"key":"e_1_2_6_24_1","doi-asserted-by":"publisher","DOI":"10.1016\/S0140-6736(73)93196-6"},{"key":"e_1_2_6_25_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.jhsa.2012.12.038"},{"key":"e_1_2_6_26_1","doi-asserted-by":"publisher","DOI":"10.1002\/mus.21431"},{"key":"e_1_2_6_27_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.clinph.2012.10.024"},{"key":"e_1_2_6_28_1","doi-asserted-by":"publisher","DOI":"10.1002\/mus.20761"}],"container-title":["Muscle &amp;
