All patients were evaluated with bilateral computed tomography scans (3\u2010dimensional) to define the H\u2010S position on the glenoid track and to measure the H\u2010S\u00a0angle. One\u2010way analysis of variance was used to compare the H\u2010S angle between the 2 groups.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>Dislocation occurred in ABD in 45 patients (44.1%) and in ADD in 57 (55.9%).

Patients whose injury occurred in the ABD position showed a higher H\u2010S angle, leading to an increased risk of engagement, because the long axis of the H\u2010S lesion is parallel to the glenoid in a position of function. Thus arm position at\u00a0the\u00a0time of the initial instability event may be a risk factor for engagement and higher risk of recurrence.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Level\u00a0of\u00a0Evidence<\/jats:title>\n                    <jats:p>Level IV, prognostic case series.<\/jats:p>\n                  <\/jats:sec>","DOI":"10.1016\/j.arthro.2016.01.022","type":"journal-article","created":{"date-parts":[[2016,3,31]],"date-time":"2016-03-31T20:49:25Z","timestamp":1459457365000},"page":"1509-1514","update-policy":"https:\/\/doi.org\/10.1016\/elsevier_cm_policy","source":"Crossref","is-referenced-by-count":39,"title":["Radiographic Analysis of the Hill\u2010Sachs Lesion in\u00a0Anteroinferior Shoulder Instability After First\u2010Time Dislocations"],"prefix":"10.1002","volume":"32","author":[{"given":"Giovanni","family":"Di Giacomo","sequence":"first","affiliation":[{"name":"Department of Orthopaedic Surgery Concordia Hospital for Special Surgery Rome Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Petar","family":"Golijanin","sequence":"additional","affiliation":[{"name":"Geisel School of Medicine at Dartmouth Hanover New Hampshire U.S.A."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"George","family":"Sanchez","sequence":"additional","affiliation":[{"name":"Sports Medicine Service Massachusetts General Hospital Boston Massachusetts U.S.A."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Matthew T.","family":"Provencher","sequence":"additional","affiliation":[{"name":"Sports Medicine Service Massachusetts General Hospital Boston Massachusetts U.S.A."}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2016,3,30]]},"reference":[{"key":"e_1_2_2_2_2","doi-asserted-by":"publisher","DOI":"10.2106\/00004623-200608000-00010"},{"key":"e_1_2_2_3_2","doi-asserted-by":"publisher","DOI":"10.1177\/036354659702500614"},{"key":"e_1_2_2_4_2","doi-asserted-by":"publisher","DOI":"10.1016\/0749-8063(89)90138-2"},{"key":"e_1_2_2_5_2","doi-asserted-by":"publisher","DOI":"10.2106\/00004623-198466020-00001"},{"key":"e_1_2_2_6_2","doi-asserted-by":"publisher","DOI":"10.1148\/35.6.690"},{"key":"e_1_2_2_7_2","doi-asserted-by":"publisher","DOI":"10.1177\/03635465980260012301"},{"key":"e_1_2_2_8_2","doi-asserted-by":"publisher","DOI":"10.2106\/00004623-197860010-00001"},{"key":"e_1_2_2_9_2","doi-asserted-by":"publisher","DOI":"10.1016\/S1058-2746(95)80020-4"},{"key":"e_1_2_2_10_2","doi-asserted-by":"publisher","DOI":"10.1177\/0363546509350295"},{"key":"e_1_2_2_11_2","doi-asserted-by":"publisher","DOI":"10.1053\/jars.2000.17715"},{"key":"e_1_2_2_12_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.arthro.2013.10.004"},{"key":"e_1_2_2_13_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.jse.2006.12.012"},{"key":"e_1_2_2_14_2","doi-asserted-by":"publisher","DOI":"10.1177\/2325967113496213"},{"key":"e_1_2_2_15_2","unstructured":"Chong JJR Beaumont\u2010Courteau M Martineau PA Powell T.
