50-135Akiva ben Joseph

Saying of Akiva ben Joseph extracted from the book Mekilta de-Rabbi Yishmael (ca. 200). Tractate was written in Israel, and interprets about a quarter of the chapters in Exodus. The rabbi mentions the ligamentum capitis femoris (LCF) of the animal. See our commentary at the link: 50-135Akiva ben Joseph [Rus].

Tractate Kaspa. 5:19

R. Akiva says: It need not be written (that eating meat and milk is forbidden), for it follows a fortiori, viz.: If the thigh sinew (gid hanasheh), which is not forbidden to be cooked, is forbidden to be eaten, then meat and milk, which is forbidden to be cooked, how much more so should it be forbidden to be eaten! (Transl. by Rabbi_Shraga_Silverstein; original source: sefaria.org)

1886LesshaftP

According to the author, the ligamentum capitis femoris (LCF) reduces shocks and impacts of the articular surfaces. In addition, P. Lesshaft states an anatomical fact: the LCF is located vertically under the part of the acetabulum, which mainly bears the weight of the body. The text is prepared for machine translation using a service built into the blog from Google or your web browser. In some cases, we have added links to quotations about LCF available on our resource, as well as to publications posted on the Internet.

Tiktaalik roseae

TIKTAALIK ROSEAE The first truly tetrapod animal (Limbed tetrapods) is recognized as the lobe-finned fish Tiktaalik roseae (clade Elpistostegalia), discovered in rocks aged about 375 Ma (2006DaeschlerEB_JenkinsJrFA; 2008ShubinN; 2017ShubinN). Discoveries in recent years have allowed us to place the taxa of early tetrapodomorphs in the following order: Tinirau, Eusthenopteron, Megalichthys, Panderichthys, Qikiqtania, Tiktaalik, Elpistostege, Parmastega, Ventastega, Acanthostega, Elginerpeton, Ymeria, Ichthyostega (2022StewartTA_ShubinNH). The closest ancestor of Tiktaalik roseae, the fragments of the skeleton of which are relatively well preserved, is Panderichthys.

163-192Galen

Fragment from the treatise Galen. On anatomical procedures (Περὶ Ἀνατομικῶν Ἐγχειρήσεων, ca. 163-192). The author writes about the high resiliency and hardness of ligamentum capitis femoris (LCF), and also notes its connective function. See our commentary at the link: 163-192Galen [Rus], and 2020ArkhipovSV_ProlyginaIV . Quote [Grc] Περὶ Ἀνατομικῶν Ἐγχειρήσεων. Βιβλιον B. K εφ . ι ʹ .

An excerpt from the article by Morris H. Dislocations of the Thigh: their mode of occurrence as indicated by experiments, and the Anatomy of the Hip-joint (1877, pp. 161-170). The author noted that the ligamentum capitis femoris (LCF) is stretched during flexion, adduction, and external rotation. It was found that the LCF is always damaged in hip dislocations, is more often torn from the femur, and is rarely ruptured. Discussion of article see article 1877BrookeC .

RECENTLY, whilst making various dissections of the hip-joint, the usually accepted doctrine that dorsal and ischiatic dislocations of the femur occur when the thigh is in a position of adduction appeared to me as very improbable, on anatomi...

1857HyrtlJ

The author discusses the anatomy, structure, and role of the ligamentum capitis femoris (LCF). Based on his own research, Josef Hyrtl asserts that the vessels of the LCF do not participate in supplying blood to the femoral head. The author highlights the high strength of the LCF and changes in congenital dislocations. Apparently, this work was the first to suggest that the LCF serves as a conductor of inflammatory processes and a cause of coxalgia. Hyrtl J.

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...

1879MorrisH

Fragments of the book Morris H. The anatomy of the joints of man (1879) dedicated to ligamentum capitis femoris (LCF). The author discusses the anatomy of the LCF and describes his experiments to study its movement. Quote p p . 318-319 The acetabulum is partly articular, partly non-articular. The articular portion is of horseshoe shape, and extends inwards from the margin, more or less. It is altogether deficient at the cotyloid notch, which corresponds with the gap of the horseshoe. It is the widest at the iliac part, where it is over one inch from without inwards; then it very gradually gets narrower along the ischium, but widens out again at the ischial end of the cotyloid notch ; forwards from the pubo-iliac suture it narrows more rapidly, and does not extend quite up to the pubic end of the cotyloid notch. At its narrowest point in an adult bone it measures half an inch in width. When coated with cartilage, and fringed round with the cotyloid ligament, it fits ve...

Australian Aborigines

AUSTRALIAN ABORIGENES The first cuneiform texts appeared at the dawn of the Sumerian civilization in the period between 3500-3100 BCE. Due to the fact that before this interval there was no writing, an older text mentioning ligamentum capitis femoris (LCF) will never be found. Perhaps a drawing or pictogram of it will be found on a stone. Our assumption is inspired by the study of the rock art of the Australian Aborigines in the style of «X-ray art». Ancient artists, depicting animals and people, often drew bones, internal and external organs, and also designated joints. The minimum age of the early X-ray painting on the western Arnhem Land Escarpment in northern Australia is 5068-6636 years (2017JonesT_WesleyD). Here, in the area of the Burrungui (Nourlangie) and Madjedbebe (Malakunanja II) shelters, rich in rock art, human settlements existed 24-20 Kya (2017MaySK_SanzID). Modern comprehensive analysis indicates the beginning of the settlement of Australia and the territory near...
