1495Johannes de Ketham

Fragment from the book Johannes de Ketham. Fasciculus medicine (1495). An excerpt from the treatise by Mondino de Luzzi describing the anatomy and role of ligamentum capitis femoris (LCF) damage in the genesis of hip diseases. The pathogenesis of lameness and soft tissue atrophy of the leg in LCF pathology is discussed. The cited author uses and explains a rare synonym for LCF – « vertebrum ». The original in Latin in our adaptation. The treatise by Mondino de Luzzi was also published in other works: 1541MondinoL_DryanderJ , 1550CortiM . See our commentary at the link: 1495Johannes de Ketham [Rus]. Quote. [Lat] De esse ossium & cuibus in locis dirigunt.

Fragments from the book: Braus H. Angeborene Gelenkveränderungen, bedingt durch künstliche Beeinflussung des Anlagemateriales (1921). The author describes the anatomy, attachment, shape, properties and changes in pathology of the ligamentum capitis femoris (LCF). The text in German. The text in Russian is available at the following link: 1921BrausH . Quote pp. 523-524. Eine Besonderheit der Hüftpfanne ist ein Fenster in ihrer Wandung. Der knöcherne Rand, an welchem die Pfannenlippe angeheftet ist, ist nach unten zw breit eingeschnitten, Incisura acetabuli (Abb. 90). Die Pfannenlippo ist trotzdem ein geschlossener Ring, weil die genannte Lücke durch ein Band, Ligamentum transversum acetabuli. überbrückt wird und weil die Pfannenlippe auf dieses Band fortgesetzt ist (Abb. 258). So ist der ventil artige Abschluß des Pfannenrandes gegen den Schenkelkopf gewahrt und trotz dem der Eintritt eines Bandes in den Innenraum des Gelenkes durch das Fenster unterhalb des Bandes möglich.

1833GerdyPN

P.N. Gerdy, in his experiment, discovered tensioning of the ligamentum capitis femoris (LCF) during thigh adduction. At the same time, it was noted for the first time that the consequence of LCF tension during hip adduction is a downward and lateral displacement of the femoral head. Normally, this mechanism provides unloading of the upper articular surfaces when supporting one leg (see 1874SavoryWS ). The translation from French was done in collaboration with ChatGPT 3.5. Gerdy PN. Physiologie médicale, didactique et critique. T. 1. Paris: Librairie de Crochard, 1833. [fragment] Quote pp. 551-554 L'inclinaison de la cuisse en dehors, que l'on nomme son abduction, est un mouvement assez étendu, mais qui pourtant ne permet pas à la cuisse de se placer perpendiculairement à sa direction verticale.

LCF Mechanics

Mechanics OF THE Ligamentum Capitis Femoris Announcement: A new scientific direction « Mechanics of the Ligamentum Capitis Femoris» has been formed. Definition: A section of physiology that develops issues of applying the doctrine of the ligamentum capitis femoris (LCF), its movements and forces to solving medical and biological problems. Synonyms: LCF Mechanics Mechanics of the Ligamentum Capitis Femoris Ligamentum Capitis Femoris Mechanics Ligament of the Head of Femur Mechanics L igamentum Teres Femoris Mechanics Round Ligament of Femur Mechanics Postulates of LCF Mechanics: Strong, flexible, and non-stretchable with specific attachment points. Limits adduction, rotation, and cranial displacement of the femur. Shunts load on the femoral head and the abductor muscle group of the hip joint. Ensures rhythmicity, symmetry, and energy efficiency of walking. Performs the function to suspend the pelvis during single-leg support. T...

1730CheseldenW

Fragments from the book Cheselden W. The Anatomy of the Human Body (1730). The author draws attention to the role of ligamentum capitis femoris (LCF) in counteracting hip dislocation and maintaining the femoral head in the joint. The work notes that the LCF is “powerful” and “short” - “about two inches” i.e. approximately 5 cm! This error will be corrected in a subsequent treatise ( 1733CheseldenW ) . Quote pp. 43 - 44 Chap. VII. Of the Ligaments At the upper part of the articulation of the Os Femoris and Os Innominatum, is a strong ligament of great consequence; it contributing very much to preserve that joint from being luxated by the weight of the body. And from the lower edge of the Acetabulum of the Os Innominatum, runs a ligament to the middle of the head of the Os Femoris, about two inches long (which the Motion in this joint requires) called Teres, or Rotundum, whose use is to prevent the Os Femoris from being luxated upwards, but down wards it will le...
