The study analyzed the overall microstructure of eleven fresh human ligamentum teres (LT) specimens. The authors suggest that the LT «... hould no longer be considered a developmental vestige, as there is evidence to suggest that it has both mechanical and biological functions within the hip joint. As such, any surgical procedures should aim to minimize excessive damage to this structure as far as possible, so as to minimize any potential loss of function.»

280-352Rava

Sayings of Rava extracted from the tractates Chullin and Horayot (Babylonian Talmud). Babylonian Talmud was written between about 450 - 550 in present-day Iraq (formerly Babylonia). The rabbi identifies the location and distal attachment site of the ligamentum capitis femoris (LCF) and demonstrates knowledge of its function. See our commentary at the link: 280-352Rava [Rus]. Quote 1. [Heb] Chullin 54b3 (original source: sefaria.org ) Quote 2. [Heb] Chullin 91a12 (original source: sefaria.org ) Quote 3. [Heb] Horayot 12a:16 (original source: sefaria.org ) Translation Quote 1. [Eng] Chullin 54b3 The Gemara addresses the matter itself: Rav Mattana says: This head of the femur that was completely dislocated renders the animal a tereifa. And Rava said: The animal is kosher, but if its sinew holding the bone in place is cut, it is a tereifa. The Gemara concludes: And the halakha is: Even if the sinew is cut, the animal is still kosher...

Human Children. Retelling of Chapter 8

Short retelling of chapter 1 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 8. THE LAND OF NOD Cain’s family settled in the land of "Nod," where they established a "city." We propose this tribal group followed a route later known as the Great Khorasan Road, leading Cain, son of Adam, to the Kermanshah Valley in the central Zagros Mountains. There, we believe he founded the settlement of "Enoch," its remnants linked to the archaeological site of Sheikh-e Abad (34°36'42"N, 47°16'11"E). In this village, the newcomers mastered musical instruments, developed metalworking techniques, and some adopted nomadic herding, living in "tents with flocks." As a farmer, Cain likely preserved knowledge of agriculture. Favorable conditions, division of labor, and acquired skills probably fueled population growth among thes...

1220-1260Hezekiah ben Manoah

Fragment from the book Hezekiah ben Manoah. Chizkuni (ca. 1240). Commentary on the Torah, was written in France between 1220-1260 ( jewishencyclopedia.com , sefaria.org ). The author briefly mentions ligamentum capitis femoris (LCF, גיד) of animals. See our commentary at the link: 1220-1260Hezekiah ben Manoah [Rus]. Quote. [Heb] Chizkuni. Genesis 32:33.1 על כן לא יאכלו כמו והוא לא כן ידמה, כלומר בדין הוא שיש לקנוס ולענוש בני ישראל מאכילת גיד הנשה שהניחו את אביהם הולך יחידי כדכתיב ויותר יע קב לבדו (original source: sefaria.org ). Translation Quote. [Eng] Chizkuni. Genesis 32:33.1 על כן לא יאכלו, “therefore it is appropriate that the Israelites do not eat, etc.;” this construction is parallel to Isaiah 10,7: והוא לא כן ידמה, “but it does not seem like this to him;” in other words: it would be right and proper to punish the Israelites not to eat that particular sinew as they should not have allowed their founding father to be exposed to hostile forces at night.

1868BeaunisH_BouchardA

Fragments from the book Beaunis H, Bouchard A. Nouveaux éléments d'anatomie descriptive et d'embryologie (1868). The authors briefly describe the anatomy of the ligamentum capitis femoris (LCF) and its role. The text is prepared for machine translation using a service built into the blog from Google or your web browser. Quote p. 186 2. Ligament rond (Fig. 52, 3). Ce ligament à la forme d'un triangle aplati de dehors en dedans, dont la base correspond au ligament transverse de l'acétabulum, la pointe à la dépression de la tête du fémur. Assez variable comme force et comme disposition, il s'insère en bas aux deux bords de l'échancrure cotyloïdienne, à la partie voisine de l'arrière-fond et au ligament transverse. Il est entouré par la synoviale et présente dans son intérieur des vaisseaux allant se rendre à la tête du fémur. La face interne est en rapport avec l'arrière-fond de la cavité cotyloïde, auquel il est rattaché par un repli synovial, sa f...

INTERACTION OF THE ILIOFEMORAL LIGAMENT AND LCF

About 200 years ago W. Weber and E. Weber (1836) experimented with anatomical preparations: https://roundligament.blogspot.com/2024/03/1836-weberwwebere.html . As a result, the brothers suggested that when leans on one leg, the body is supported by the iliofemoral ligament (IFL) and ligamentum capitis femoris (LCF). Our experiments on a mechanical model confirm this point of view: https://kruglayasvyazka.blogspot.com/2024/06/lcf_25.html ; https://kruglayasvyazka.blogspot.com/2024/06/blog-post_23.html ; https://kruglayasvyazka.blogspot.com/2024/06/lcf_23.html . Ideally, a hip replacement should contain an analogue of the ligamentum capitis femoris and an analogue of the iliofemoral ligament. #ligamentum_teres #hip #biomechanics #ligamentum_capitis_femoris #endoprosthesis Publication in the facebook group 04/24/2025. ...
