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 primura est os foemoris supra quod fabricatae sunt spondiles dorsi: & per consequens totum corpus in parte inferiori habet pixidem quondam, in cuius concauitate locata est extremitas rotunda canna coxae, que uocatur uertebrum. 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...

Localization of LCF Pathology

  Version : 20240418 Localization of LCF pathology is classified based on the anatomical-topographical principle. It is assumed that the LCF does not end near the attachment site but penetrates into it. LOCALIZATION OF LCF PATHOLOGY 1. Middle part 2. Distal end 3. Proximal end 4. Distal attachment area 5. Proximal attachment area 6. Medial surface 7. Lateral surface 8. Anterior edge 9. Posterior edge 10. Transsynovial 11. Subsynovial 12. Total Lesion The medial surface faces the bottom of the acetabulum. The lateral surface faces the femoral head. Transsynovial pathology implies changes including or only involving the synovial membrane. Subsynovial pathology is localized exclusively beneath the synovial membrane of LCF. Pathology can involve multiple parts of LCF, for example, damage to the distal end and proximal attachment area in a transacetabular fracture.   The distal part of LCF attaches directly to the bone of fovea capitis femoris.

Grok. Review of the Article by S.V. Arkhipov "Why Restoration of the Acetabular Labrum May Be Ineffective?".

  At our request, Grok, artificial intelligence developed by xAI, wrote a review of the article by Arkhipov SV. Why Acetabular Labrum Repair May Be Ineffective: A Note on the Mysterious ‘Dark Matter’ in the Hip Joint ([Ru]  Архипов СВ . Почему восстановление вертлужной губы может быть неэффективно?: Заметка о таинственной «темной материи» в тазобедренном суставе. 06.04.2025 ). In accordance with the comments, the article was revised and sent for re-review to the ChatGPT language model prepared to assist in the analysis and editing of texts (OpenAI, 2025).  Below is the original text of the review by Grok: Review of the Article by S.V. Arkhipov "Why Restoration of the Acetabular Labrum May Be Ineffective?: A Note on the Mysterious 'Dark Matter' of the Hip Joint". This review focuses on the analysis of argumentation, as requested. The author asserts that restoration of the acetabular labrum fails to prevent hip joint instability and osteoarthritis when the ligame...

LCF of Pithecanthropus

  The hip joint of Pithecanthropus erectus (Homo erectus) had a ligament of the head of the femur, in Latin called the ligamentum capitis femoris (LCF). The femur of a male specimen was first discovered in 1892 by Eugène Dubois (1858-1940) on the island of Java (2004DeVosJ). The age of the sediment preserving the remains of the Java Man is estimated to be approximately in the range of 540-430 thousand years (2015JoordensJC_RoebroeksW). On the femoral head, a deep pit of the femoral head is noticeable—the trace of the distal attachment of the LCF ( sketchfab.com ). The location of the pit on the femoral head of Pithecanthropus is identical to that of Homo sapiens. In light of this, we assume that the Java Man walked similarly to anatomically modern humans. Illustration: Pithecanthropus had LCF The left femur of Java Man (Pithecanthropus erectus, Homo erectus), specimen from the Darwin Museum (Moscow); view from the medial side (photo by the author).

   Palmerani Á , drawing Jacob wrestling with the angel (1802 ).  Depicting the circumstances and mechanism of the ligamentum capitis femoris (LCF) injury based on the description in the Book of Genesis: 25 And Ja cob was left alone; and there wrestled a man with him until the breaking of the day. 26 And when he saw that he could not prevail against him, he struck against the hollow of his thigh ; and the hollow of Jacob's thigh was put out of joint, as he was wrestling with him. … 33 Therefore do the children of Israel not eat the sinew which shrank, which is upon the hollow of the thigh, unto this day; because he struck against the hollow of Jacob's thigh on the sinew that shrank.  ( 1922LeeserI , Genesis (Bereshit) 32:25-26,33) More about the plot in our work:  Ninth month, eleventh day   ( 2024 АрхиповСВ.
