With Irony About the Author

More than a quarter of a century ago, I asked myself the question: why do penguins and people waddle?

I studied the locomotion of people and animals, movement of machines, observed in zoos and museums, studied the structure of birds and human, experimented and analyzed, developed a mathematical apparatus. For the penguins the operation was developed: circular periacetabular osteotomy of the pelvis with rotational transposition of the proximal area of attachment of the ligament of the head of femur (ligamentum capitis femoris, ligamentum teres). A similar operation can improve the gait of some people too.

In the beginning, there was a question...

Human LCF intersection

HUMAN LCF INTERSECTION In the south of China, in the Guangxi Zhuang Autonomous Region, the archaeological Neolithic site of Dingsishan was investigated. Burials of 355 people were found in this place. The authors of the article (2024YeZ_LiFJ) identified 91 skeletons with traces of manipulations with the remains. They are attributed to burials of the Dingsishan III-IV phase, aged 8.0-4.5 thousand years. 13 notches were found on the proximal part of various femurs. « Cutmarks on the femoral head, neck and intertrochanteric line, as well as along the medial linea aspera of the femoral shaft, suggest that soft tissue around the hip, including the iliofemoral ligament and the iliacus and adductor muscles, was severed to disarticulate the joint.» This and other postmortem bone injuries «... suggests that corpse treatment at Dingsishan included disarticulation » (2024YeZ_LiFJ). Figure 4 of the cited article shows the distribution and direction of cutmarks on human skeletons from Dingx...

The First Scientific Mention

European science has known the LCF for about 2500 years. It is the most important functional connection of the hip joint. The first person to describe the LCF was Hippocrates (c. 460-370 BCE). A written mention of the LCF is found in §1 of his treatise "On the Instrument of redactions". In our opinion, a book created in the library of the Asclepeion of the island of Kos. Hippocrates did not dissection of the human body, did not operate on the hip joint, did not have a CT scan and MRI. How he could discover the LCF? In our view, it is possible that Hippocrates treated a patient with an open hip dislocation.

1857RüdingerN

Fragments from the book Rüdinger N. Die Gelenknerven des menschlichen Körpers (1857). The author found that the inferior branch of the obturator nerve reaches the ligamentum capitis femoris (LCF). The text is prepared for machine translation using a service built into the blog from Google or your web browser. Quote p. 18 Die das Gelenk auskleidende Synovialmembran gibt einen scheideähnlichen Fortsatz zum Lig. teres und communicirt zuweilen mit dem Schleimbeutel des Musc. iliacus internus. Quote p. 19 Das untere weiter nach abwärts laufende Aestchen (die Fortsetzung des Stämmchens), geht etwas tiefer nach vorn und löst sich zerstreut in dem Lig. pubo-femorale, mehr noch in dem Lig. ischio-femorale auf. Bei vorsichtiger Präparation und an Präparaten, die mit Essigsäure behandelt waren, konnte ich in der Regel einen Faden beobachten, der zur Incisura acetabuli geht, mit den Gefässen in das Gelenk tritt und sich in dem von Fett durchdrängten Zellgewebe und dem L...

If the dislocated and displaced hip could not remain in place, then the physician [Hippocrates] would have clearly indicated the incurability of this case, so that we would not be led astray. Don't those who hold the opposite opinion know about the nature of joints, ligaments and the teachings about these things in general? After all, the physician considered the cause of the mild or, on the contrary, complex displacement and ...

An excerpt from the article by Parsons FG. The joints of mammals compared with those of man: a course of lectures delivered at the Royal College of Surgeons of England (1899, pp. 301-306). The paper discusses the anatomy and presence of the ligamentum capitis femoris (LCF) in different animals. The author found in an experiment that in kangaroos, the LCF was stretched during hip extension. Below we publish an excerpt from the abstract and a critique of the lecture in the Lancet.
