1910SuttonHA_DrinkerCK

  Fragments from the book Sutton HA, Drinker CK. Osteology and syndesmology (1910). The selected fragments discuss the anatomy and topography of the ligament of the femoral head (LCF). According to the authors, this structure has low strength, but Galen of Pergamon (2-3rd cent.) described it as «the strongest» ( 1829KühnCG ). [Eng] Quote 1. p. 76 . The Cotyloid Lig't., or Cartilage, surmounts the edge of the Acetabulum except where it is broken by the Notch. This ligament simply deepens the cavity. The centre of the Acetabulum, by a rough area, the Cotyloid Fossa, attaches the Ligamentum Teres. Quote 2. p. 79. Head. Slightly more than a half sphere in shape. An articular surface for the Acetabulum occupies it, except at a fossa which attaches the Ligamentum Teres. Quote 3. p. 86. Two connect the bones. They are: 1. Ligamentum Teres: — Weak. Passes between the centre of the Acetabulum and the oval fossa upon the Head of the Femur. It lies outside the synovial membrane. External link...

1541MondinoL_DryanderJ

  Fragment from the book Mondino de Luzzi, Dryander J. Anatomia Mundini (1541). An early description of the anatomy and role of the ligamentum capitis femoris (LCF) is presented. The pathogenesis of lameness and soft tissue atrophy in LCF pathology is discussed. For more details, see the commentary in  1541MondinoL_DryanderJ [Rus] .  Quote p. 62. [Lat] De anatomia cruris [&] pedis. Postea eleua musculos & chordas &, uide ossa.

Et in medio amborum in parte anteriori est quod dam ligamentum, quod aliomodo porestuocari uertebrum: & quando hoc uel primum resilit foras: tunc niecesse ed hominem claudicare, quia crus hic elongatur & firmari non potest; & totum non bene potest supportari: & necesse eit etiam ut crus tab...

1873MeyerGH

  Professor  Georg Hermann von Mayer discovered a pressure mark from the ligamentum capitis femoris (LCF) on the head of the femur. In the fragment presented to your attention, the author points out that the named depression indicates the tension of the LCF in the position of flexion and external rotation of the hip. This idea of Mayer was later repeatedly cited, see, for example, the work of Hermann Welcker  " Ueber das Hüftgelenk, nebst einigen Bemerkungenüber Gelenke überhaupt, insbesondere über das Schultergelenk " (1876). von Meyer GH. Die Statik und Mechanik des menschlichen Knochengerüstes. Edited, Leipzig: Verlag von Wilhelm Engelmann; 1873. [fragment] Quote pp. 342-344   Neben der Gelenkkapsel befindet sich in dem Hüftgelenke noch ein eigenthümlicher Bandapparat, das ligamentum teres, über dessen Bedeutung sehr verschiedene Auffassung gefunden wird. Von der einen Seite wird ihm nämlich entschieden ...
