ILIOTIBIAL TRACT & LCF

  ILIOTIBIAL TRACT & LCF There is an opinion that the iliotibial tract, like the ligamentum capitis femoris (LCF), provides pressing of the acetabulum to the lower surface of the femoral head. I think that this is not true. The tract is located above and lateral to the center of rotation of the hip joint. Its force vector, like the force vector of the abductor group of muscles, presses the acetabulum to the upper part of the femoral head, which increases the load on it. The ligamentum capitis femoris acts in the opposite direction. Below is a diagram for a single-support position. #ligamentum_teres   #hip   #biomechanics   #ligamentum_capitis_femoris Publication in the facebook group 04/12/2025.                                                                              ...

1851HyrtlJ

  The author expresses a classic view on the functions of the ligamentum capitis femoris (LCF): a conductor of blood vessels and a limiter of adduction of the femur. J. Hyrtl believed that it was impossible to completely dislocate the hip without tearing the LCF. Hyrtl J. Lehrbuch der Anatomie des Menschen, mit Rücksicht auf physiologische Begründung und praktische Anwendung. Wien: W. Braumüller, 1851. [fragment] Quote p. 265 In der Höhle des Gelenks liegt das runde Band des Schenkelkopfes (Lig. teres), welches an der Incisura acetabuli entspringt, und bei richtiger Neigung des Beckens, senkrecht zur Grube des Schenkelkopfes aufsteigt. Es beschränkt dieses Band die Zuziehung des Schenkels, und schreibt zugleich den durch die Incisura acetabuli eindringenden Blutgefässen den Weg vor, den sie zum Oberschenkelkopfe zu nehmen haben. Da das Band, wenn es in die Höhle des Gelenkes vorragen würde, durch Reibung viel zu leiden hätte, so...

1902RilkeRM

    Works of art that mention ligamentum capitis femoris (LCF) are extremely rare. One such work is the poem «Der Schauende» ( He Who Visions, The Seer, The Man Watching, The Beholder)  b y Rainer Rilke. Below is the original text in German.   Der Schauende 1. Ich sehe den Bäumen die Stürme an, die aus laugewordenen Tagen an meine ängstlichen Fenster schlagen, und höre die Fernen Dinge sagen, die ich nicht ohne Freund ertragen, nicht ohne Schwester lieben kann. 2. Da geht der Sturm, ein Umgestalter, geht durch den Wald und durch die Zeit, und alles ist wie ohne Alter: die Landschaft, wie ein Vers im Psalter, ist Ernst und Wucht und Ewigkeit. 3. Wie ist das klein, womit wir ringen, was mit uns ringt, wie ist das groß; ließen wir, ähnlicher den Dingen, uns so vom großen Sturm bezwingen, - wir würden weit und namenlos. 4. Was wir besiegen, ist das Kleine, und der Erfolg selbst macht uns klein. Das Ewige und Ungemeine will nicht von uns gebogen sein. Das ist der Enge...

1823CooperA

  According to the author, the ligamentum capitis femoris (LCF) is intended to prevent dislocations in all directions. A. Cooper discusses traumatic obturator dislocation of the hip joint and LCF injury in more detail. Cooper A. Abhandlung über Luxationen und Fracturen der Gelenke des Unterkiefers, der obern Extremitäten und der Knochen des Rumpfes. Aus dem Englischen. Weimar : Landes-Industrie-Comptoir, 1823. [fragments] Quote p. 1 4 8 Das ligamentum teres hat die Bestimmung, Luras tionen nach allen Richtungen hin zu verhindern, besonders aber nach abwärts, denn wenn die Schenkel weit ausein andergespreizt werden, wie z. B. bei'm Fechten, so würde der Kopf des linken Oberschenkelknochens in Gefahr feyn, aus seiner Gelenkhöhle zu schlüpfen, was aber durch dieses Ligament verhindert wird. The ligamentum teres is designed to prevent dislocations in all directions, especially downwards, because when the thighs are widely ab...

A Novel Technique for Proximal Fixation

  Arkhipov SV. A Novel Technique for Proximal Fixation of Ligamentum Capitis Femoris Reconstruction: The Gifts of the Magi for Orthopedic Surgeons. About Round Ligament of Femur. January 14, 2026. DOI: 10.13140/RG.2.2.25269.33763 https://roundligament.blogspot.com/2026/01/the-gifts-of-magi-for-orthopedic.html Abstract Purpose: To describe an experimental technique for proximal fixation in ligamentum capitis femoris (ligamentum teres femoris; LCF) reconstruction using pubic and ischial portions anchored in corresponding pelvic bone tunnels, tested on synthetic hip joint models, and to propose it’s for arthroscopic application with visualization via an inferior portal and femoral tunnel. Methods: Synthetic polyurethane bone analogs (Synbone) of the pelvis and proximal femur were used to fabricate hip joint models. Acetabular cartilage analogs were created from self-curing plastic compound. Femoral tunnels were drilled along the neck axis from the subtrochanteric region below the tub...

1740KulmusJA

Fragments from the book Kulmus JA. Tables anatomiques (1734). The author briefly writes about the anatomy, properties and attachment of the ligamentum capitis femoris (LCF). There are known translations of the treatise into Latin ( 1732KulmusJA ) and French ( 1734KulmusJA ). Quote p. 51 [Deu] Translation [Eng] с . In the upper part of the head there is a recess in which the round ligament is attached. Quote p. 54 [Deu] Translation [Eng] 2.) The round ligament is short but very strong; it arises at the bottom of the acetabulum and joins the fossa at the top of the femoral condyle. External links Kulmus JA.

1849QuainJ

  Fragments from the book by Jones Quain (fifth edition): Elements of anatomy Vol. 1 (1849), the first edition was published in 1828. The author writes about the anatomy of the ligamentum capitis femoris (LCF) and mentions synonyms.   Quote p. 278 THE HIP-JOINT. This is a true ball-and-socket joint, in which the globular head of the femur is received into the acetabulum or cotyloid cavity. The articulating surfaces are covered by cartilage in the greater part of their extent. It is deficient, however, at the bottom of the cavity, and also a little beneath the central point of the head of the femur; the latter marking the insertion of the round ligament, the former a shallow fossa for the lodgment of the structure which has been called the synovial gland. The connecting means in this articulation are three ligaments, viz. a capsular, cotyloid, and interarticular ligament, together with a synovial membrane. Fig. 147. Ligaments of the pelvis and hip-joint. The view is t...

Human Children. Retelling of Chapter 13

  Short retelling of chapter 13 of the essay: Arkhipov S.V. Human Children: The Origins of Biblical Legends from a Physician's Perspective. Joensuu: Author's Edition, 2025. [In Russian]  Chapter 13. PROPHETIC DREAMS After his wanderings and battles, Abraham settles in “Mamre’s oaks in Hebron.” Following these events, he experiences a divine “word in a vision” and a dream promising him lands “from Egypt’s river to the great river, Euphrates.” His family relocates to a desert along the Shur road, near the well “Beer-Lahai-Roi,” between Kadesh and Bered. In another divine appearance, Abraham is commanded to circumcise all males’ foreskins, rename Sarai as Sarah, and is told he’ll father a child at 100, despite Sarah’s barrenness at 89. That day, Abraham circumcises his son Ishmael, household males, and, at 99, himself. In Mamre’s oaks, during “daytime heat,” a mirage foretells fatherhood. The dream shifts, showing Sodom and Gomorrah’s destruction and Lot’s miraculous rescue. ...
