Recent trends have developed in placing the biceps tendon lower in the bicipital groove for a tenodesis. However, a more distal biceps tenodesis location is technically challenging when carried out arthroscopically with standard posterior and lateral portals. We aimed to establish the safety of a low\u2010anterolateral portal location for direct access to the lowest aspect of the bicipital groove.<\/jats:p><\/jats:sec><jats:sec><jats:title>Methods<\/jats:title><jats:p>An anatomical study design was used to examine portal to neurovascular structural measurements in 23 cadaveric shoulders. These shoulders had undergone low\u2010anterolateral portal placement over the inferior most aspect of the bicipital groove as determined by palpation and direct arthroscopic visualization. No arthroscopic irrigation was performed. Following this, the shoulders underwent open dissection with the cannula in place to evaluate for any potential damage to any portion of the axillary nerve.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>All of the resultant portals in this study provided direct access to the inferior most aspect of the bicipital groove, and the dissection revealed that the portal was touching a small distal axillary nerve branch on the undersurface of the anterior deltoid in nearly half of the shoulders.<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusions<\/jats:title><jats:p>The placement of a low\u2010anterolateral portal for arthroscopic biceps tenodesis at the distal bicipital groove does not produce significant neurovascular damage; the portal trajectory comes close to distal anterior branches of the axillary nerve. Given these findings, this portal should be placed bluntly to best protect these underlying neurovascular structures.<\/jats:p><\/jats:sec>","DOI":"10.1007\/s00167-013-2444-9","type":"journal-article","created":{"date-parts":[[2013,2,11]],"date-time":"2013-02-11T04:00:06Z","timestamp":1360555206000},"page":"462-466","source":"Crossref","is-referenced-by-count":10,"title":["The low\u2010anterolateral portal for arthroscopic biceps tenodesis: description of technique and cadaveric study"],"prefix":"10.1002","volume":"22","author":[{"given":"Michael L.","family":"Knudsen","sequence":"first","affiliation":[{"name":"Department of Orthopaedic Surgery University of Minnesota 2450 Riverside Ave S #R200 55454 Minneapolis MN USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jason C.","family":"Hibbard","sequence":"additional","affiliation":[{"name":"Department of Orthopaedic Surgery University of Minnesota 2450 Riverside Ave S #R200 55454 Minneapolis MN USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"David J.","family":"Nuckley","sequence":"additional","affiliation":[{"name":"Department of Physical Medicine and Rehabilitation University of Minnesota MMC 388, Office: ChRC 366B, 420 Delaware St. SE 55455 Minneapolis MN USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jonathan P.","family":"Braman","sequence":"additional","affiliation":[{"name":"Department of Orthopaedic Surgery University of Minnesota 2450 Riverside Ave S #R200 55454 Minneapolis MN USA"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2013,2,12]]},"reference":[{"key":"e_1_2_7_2_1","doi-asserted-by":"publisher","DOI":"10.1016\/S0030\u20105898(03)00093\u20102"},{"key":"e_1_2_7_3_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.arthro.2007.11.018"},{"key":"e_1_2_7_4_1","doi-asserted-by":"publisher","DOI":"10.1053\/jars.2002.36488"},{"key":"e_1_2_7_5_1","doi-asserted-by":"publisher","DOI":"10.1016\/S0749\u20108063(96)90206\u20106"},{"key":"e_1_2_7_6_1","doi-asserted-by":"publisher","DOI":"10.1016\/S0749-8063(01)90015-5"},{"issue":"4","key":"e_1_2_7_7_1","first-page":"503","article-title":"Tips of the trade.
