Ten cadaveric specimens of the ligamentum capitis femoris (LCF) were dissected and photographed. Magnetic resonance (MR) and Computed tomography (CT) arthrography evaluation of the anatomy of the LCF in 30 hips were performed to measure length of the ligament and to study the proximity of neurovascular structures.<\/jats:p>\n                  <jats:p>The anatomical study showed that the LCF has a pyramidal structure and a banded appearance. The thickness of the medial wall of the acetabulum 3mm superior to the inferior acetabular boundary was found to be 6.7mm (4\u20139mm) at point 1 (anterior), 4.1mm (3\u20137mm) at point 2 (central), and 6.5mm (49mm) at point 3 (posterior). Central anchors or screws were found to lie within 1.7cm (1.6\u20131.9cm) of the external iliac vein and artery. Angulation of anchors in the anterior and posterior columns in the axial plane with respect to acetabular fossa floor (the Optimal Angulation Angle or OAA), is safer (0 to 45\u00b0 the safest optimal angles). The sagittal angulation created by the safe pathway in the anterior and posterior columns with respect to the plane of the facies lunata in this area was also measured and termed the Optimal Angle of Penetration (OAP) with normal values being: 110\u00b0 (102\u2013123\u00b0) for the posterior column and 90\u00b0 (85\u201394\u00b0) for the anterior column.<\/jats:p>\n                  <jats:p>Our results suggest that reconstruction of the LCF can be safely performed if these guidelines are followed.<\/jats:p>","DOI":"10.5301\/hip.2011.8406","type":"journal-article","created":{"date-parts":[[2011,6,10]],"date-time":"2011-06-10T08:41:48Z","timestamp":1307695308000},"page":"367-372","update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":13,"title":["The Ligamentum Capitis Femoris: Anatomic, Magnetic Resonance and Computed Tomography Study"],"prefix":"10.1177","volume":"21","author":[{"given":"Luis","family":"Perez-Carro","sequence":"first","affiliation":[{"name":"Orthopaedic Surgery and Traumatology Service, Hospital Universitario Marques de Valdecilla and Medical Centre Loyalty, Santander - Spain"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Pau","family":"Golano","sequence":"additional","affiliation":[{"name":"Laboratory of Arthroscopic and Surgical Anatomy, Department of Pathology and Experimental Therapeutics (Human Anatomy Unit), University of Barcelona, Barcelona - Spain"},{"name":"Orthopaedic Surgery Department, University of Pittsburgh, Pittsburgh, Pennsylvania - USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jordi","family":"Vega","sequence":"additional","affiliation":[{"name":"Orthopaedic Surgery and Traumatology Service, Hospital San Cugat Asepeyo, Barcelona - Spain"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Natalia F.","family":"Escajadillo","sequence":"additional","affiliation":[{"name":"Orthopaedic Surgery and Traumatology Service, Hospital Universitario Marques de Valdecilla and Medical Centre Loyalty, Santander - Spain"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Carlos G.","family":"Rubin","sequence":"additional","affiliation":[{"name":"Orthopaedic Surgery and Traumatology Service, Hospital Universitario Marques de Valdecilla and Medical Centre Loyalty, Santander - Spain"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Luis","family":"Cerezal","sequence":"additional","affiliation":[{"name":"Radiology Service, Santander - Spain"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"179","published-online":{"date-parts":[[2011,10,6]]},"reference":[{"key":"bibr1-hip.2011.8406","doi-asserted-by":"publisher","DOI":"10.1016\/S0278-5919(05)70285-4"},{"key":"bibr2-hip.2011.8406","doi-asserted-by":"publisher","DOI":"10.1053\/j.oto.2005.07.001"},{"key":"bibr3-hip.2011.8406","doi-asserted-by":"publisher","DOI":"10.1177\/03635465030310060701"},{"key":"bibr4-hip.2011.8406","doi-asserted-by":"publisher","DOI":"10.1002\/ca.980040403"},{"key":"bibr5-hip.2011.8406","doi-asserted-by":"publisher","DOI":"10.1016\/S0749-8063(05)80189-6"},{"key":"bibr6-hip.2011.8406","doi-asserted-by":"publisher","DOI":"10.1302\/0301-620X.88B12.18584"},{"key":"bibr7-hip.2011.8406","doi-asserted-by":"publisher","DOI":"10.1016\/j.arthro.2004.01.025"},{"key":"bibr8-hip.2011.8406","doi-asserted-by":"publisher","DOI":"10.1097\/01.bpb.0000271332.66019.15"},{"key":"bibr9-hip.2011.8406","doi-asserted-by":"publisher","DOI":"10.1016\/j.arthro.2005.02.016"},{"key":"bibr10-hip.2011.8406","author":"Briggs K.","year":"2010","journal-title":"Arthroscopic Ligamentum Teres Reconstruction."},{"key":"bibr11-hip.2011.8406","doi-asserted-by":"publisher","DOI":"10.1097\/00004424-198209000-00007"},{"key":"bibr12-hip.2011.8406","first-page":"381","volume-title":"Contributions of basic and applied Sciences to hip replacement in the older patient.","author":"Noble P.C.","year":"1994"},{"key":"bibr13-hip.2011.8406","unstructured":"GrayH.
