A posteromedial portal in the elbow is not recommended because of its proximity to the ulnar nerve. However, iatrogenic injuries to the ulnar nerve have been reported after elbow arthroscopy using the standard posterior portals, especially in posteromedial elbow joint pathologies. We present a surgical technique applicable to posteromedial elbow pathology by using ultrasound\u2010assisted posteromedial portal placement of the elbow joint. Through this technique, the position of the ulnar nerve is identified prior to portal creation and the instruments are introduced from an ulnar to radial direction, thus avoiding ulnar nerve injury.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Technique Video<\/jats:title>\n                    <jats:p>\n                      <jats:boxed-text content-type=\"video\" position=\"anchor\">\n                        <jats:graphic xmlns:xlink=\"http:\/\/www.w3.org\/1999\/xlink\" position=\"anchor\" xlink:href=\"urn:x-wiley:22126287:media:atn2bf01672:atn2bf01672-vimg-mmc1\">\n                          <jats:alt-text>video<\/jats:alt-text>\n                        <\/jats:graphic>\n                      <\/jats:boxed-text>\n                    <\/jats:p>\n                    <jats:p>\n                      <jats:bold>See video under supplementary data.<\/jats:bold>\n                    <\/jats:p>\n                  <\/jats:sec>","DOI":"10.1016\/j.eats.2017.03.024","type":"journal-article","created":{"date-parts":[[2017,7,24]],"date-time":"2017-07-24T11:17:46Z","timestamp":1500895066000},"update-policy":"https:\/\/doi.org\/10.1016\/elsevier_cm_policy","source":"Crossref","is-referenced-by-count":8,"title":["Ultrasound\u2010Assisted Posteromedial Portal Placement of the Elbow Joint to Prevent Ulnar Nerve Injury"],"prefix":"10.1002","volume":"6","author":[{"given":"Hiroshi","family":"Ohuchi","sequence":"first","affiliation":[{"name":"Department of Sports Medicine Kameda Medical Center Kamogawa\u2010shi Chiba\u2010ken Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Rolando Junior L.","family":"Torres","sequence":"additional","affiliation":[{"name":"Department of Sports Medicine Kameda Medical Center Kamogawa\u2010shi Chiba\u2010ken Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Kotaro","family":"Shinga","sequence":"additional","affiliation":[{"name":"Department of Sports Medicine Kameda Medical Center Kamogawa\u2010shi Chiba\u2010ken Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ken","family":"Ichikawa","sequence":"additional","affiliation":[{"name":"Department of Sports Medicine Kameda Medical Center Kamogawa\u2010shi Chiba\u2010ken Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yuki","family":"Kato","sequence":"additional","affiliation":[{"name":"Department of Sports Medicine Kameda Medical Center Kamogawa\u2010shi Chiba\u2010ken Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Soichi","family":"Hattori","sequence":"additional","affiliation":[{"name":"Department of Sports Medicine Kameda Medical Center Kamogawa\u2010shi Chiba\u2010ken Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Shin","family":"Yamada","sequence":"additional","affiliation":[{"name":"Department of Sports Medicine Kameda Medical Center Kamogawa\u2010shi Chiba\u2010ken Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2017,7,24]]},"reference":[{"key":"e_1_2_2_2_1","doi-asserted-by":"publisher","DOI":"10.1016\/S0749-8063(85)80038-4"},{"key":"e_1_2_2_3_1","doi-asserted-by":"publisher","DOI":"10.2106\/00004623-199274010-00010"},{"key":"e_1_2_2_4_1","doi-asserted-by":"publisher","DOI":"10.2106\/00004623-200101000-00004"},{"key":"e_1_2_2_5_1","doi-asserted-by":"publisher","DOI":"10.5435\/00124635-200605000-00007"},{"key":"e_1_2_2_6_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.jse.2005.09.012"},{"key":"e_1_2_2_7_1","doi-asserted-by":"publisher","DOI":"10.1016\/0749-8063(95)90200-7"},{"key":"e_1_2_2_8_1","unstructured":"AuerbachD.Elbow arthroscopy technique: a small joint series technique guide [Internet].
