The origin of the IRA from the medial femoral circumflex artery and the course to its terminus were dissected. The IRA position relative to the femoral neck was described using a clock-face system: 12:00 cephalad, 3:00 anterior, 6:00 caudad, and 9:00 posterior.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results:<\/jats:title>\n                    <jats:p>The IRA originated from the medial femoral circumflex artery and traveled within the Weitbrecht ligament in all hips. The IRA positions were 7:00 (n = 13), 7:30 (n = 15), and 8:00 (n = 2). The IRA was 0:30 anterior to (n = 24) or at the same clock-face position (n = 6) as the lesser trochanter. The mean intraarticular length was 20.4 mm (range 11\u201365, SD 9.1), and the mean extraarticular length was 20.5 mm (range 12\u201331, SD 5.1).<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusions:<\/jats:title>\n                    <jats:p>The intraarticular course of the IRA lies within the Weitbrecht ligament between the femoral neck clock-face positions of 7:00 and 8:00. A medial buttress plate positioned at 6:00 along the femoral neck is anterior to the location of the IRA and does not endanger the blood supply of the femoral head. The improved understanding of the IRA course will facilitate preservation during intraarticular approaches to the femoral neck and head.<\/jats:p>\n                  <\/jats:sec>","DOI":"10.1097\/bot.0000000000001377","type":"journal-article","created":{"date-parts":[[2018,12,18]],"date-time":"2018-12-18T14:25:23Z","timestamp":1545143123000},"page":"111-115","source":"Crossref","is-referenced-by-count":33,"title":["Vascular Anatomy of the Medial Femoral Neck and Implications for Surface Plate Fixation"],"prefix":"10.1097","volume":"33","author":[{"given":"Sara M.","family":"Putnam","sequence":"first","affiliation":[{"name":"Department of Orthopaedic Surgery, Washington University School of Medicine, St. Louis, MO;"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Cory A.","family":"Collinge","sequence":"additional","affiliation":[{"name":"Department of Orthopaedics and Rehabilitation, Vanderbilt University, Nashville, TN;"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Michael J.","family":"Gardner","sequence":"additional","affiliation":[{"name":"Department of Orthopaedic Surgery, Stanford University School of Medicine, Redwood City, CA; and"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"William M.","family":"Ricci","sequence":"additional","affiliation":[{"name":"Hospital for Special Surgery, New York, NY."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Christopher M.","family":"McAndrew","sequence":"additional","affiliation":[{"name":"Department of Orthopaedic Surgery, Washington University School of Medicine, St. Louis, MO;"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"276","reference":[{"key":"R1-20230828","doi-asserted-by":"crossref","first-page":"1711","DOI":"10.2106\/00004623-200408000-00015","article-title":"Operative treatment of femoral neck fractures in patients between the ages of fifteen and fifty years","volume":"86A","author":"Haidukewych","year":"2004","journal-title":"J Bone Joint Surg Am."},{"key":"R2-20230828","doi-asserted-by":"crossref","first-page":"1654","DOI":"10.2106\/JBJS.G.01353","article-title":"Results of internal fixation of Pauwels type-3 vertical femoral neck fractures","volume":"90","author":"Liporace","year":"2008","journal-title":"J Bone Joint Surg Am."},{"key":"R3-20230828","doi-asserted-by":"crossref","first-page":"527","DOI":"10.1007\/s00402-003-0579-8","article-title":"Surgical treatment of displaced stress fractures of the femoral neck in military recruits: a report of 42 cases","volume":"123","author":"Lee","year":"2003","journal-title":"Arch Orthop Trauma Surg."},{"key":"R4-20230828","doi-asserted-by":"crossref","first-page":"15","DOI":"10.2106\/00004623-199401000-00003","article-title":"Outcomes after displaced fractures of the femoral neck.
