ABOUT THE PROJECT

The blog is dedicated to the ligament of the head of femur, known in Latin as ligamentum capitis femoris (LCF). In our opinion, this is a crucial element of the hip joint, found in the majority of vertebrates, including humans. This structure is significant for the functioning not only of the lower limb but the entire musculoskeletal system. LCF is involved in walking and helps maintain certain types of upright posture. It connects the pelvis and femur, restricts movements, and redistributes the load in the hip region. Dysfunction, displacement of attachment points, and pathological changes in LCF are the initial links in the pathogenesis of hip osteoarthritis, congenital hip dysplasia, congenital dislocation of the hip, aseptic (avascular) necrosis, and femoral head osteochondropathy. Preventing or interrupting the development of these disabling conditions could be achieved through successful therapeutic and surgical treatment of LCF pathology with normalizing its functioning.

The creation of blog articles we are guided by a scientific approach, involving references to primary sources and verified information. Unlike conventional journal publications, our works imply constant updates. This is because the study of LCF continues to this day, despite its beginning was in Mesopotamia 2000-1600 years before the common era. New facts can not only complement previously written material but also influence conclusions. We advocate for the continuous improvement of the style and form of articles, their correction, expansion, and fragmentation. Such dynamic interactive works, in our view, are a requirement of modern natural science and may soon become a standard. Each blog page has a comments section, providing an opportunity to express opinions. It is expected that specialists knowledgeable in the subject will make use of this. Exchanging views will enhance the exploration of the topic and encourage participants in the discussion to conduct their own research. Questions and critical remarks to the author are welcomed!

With sincere respect to you,

Original text:

Блог посвящен связке головки бедра, на латинском языке именуемой ligamentum capitis femoris (LCF). По нашему мнению, это важный элемент тазобедренного сустава, который обнаруживается у подавляющего числа позвоночных, включая человека. Данная анатомическая структура значима для функционирования не только нижней конечности, но всей опорно-двигательной системы. LCF задействована при ходьбе и участвует в поддержании отдельных вертикальных поз. Она соединяет таз и бедро, ограничивает движения, а также перераспределяет нагрузку в тазобедренной области. Дисфункция, дислокация мест крепления и патологические изменения LCF – начальные звенья патогенеза коксартроза, дисплазии тазобедренного сустава, врожденного вывиха бедра, асептического некроза и остеохондропатии головки бедренной кости. Предотвратить или прервать развитие этих инвалидизирующих заболеваний могло бы успешное терапевтическое и хирургическое лечение патологии LCF с нормализацией ее функционирования.

При создании статей блога главенствует научный подход, предполагающий ссылки на первоисточники и проверенные сведения. В отличие от общепринятых журнальных публикаций, наши работы подразумевают обновление. Это обусловлено тем, что изучение LCF продолжается до сих пор, несмотря на то, что началось еще в Месопотамии 2000-1600 лет до современной эры. Новые факты способны не только дополнить ранее написанный материал, но и повлиять на выводы. Мы сторонники постоянного улучшения стиля и формы статей, их исправления, увеличения и фрагментации. Подобные динамические интерактивные работы, с нашей точки зрения, – требование современного естествознания и, вероятно, скоро будут стандартом. На каждой странице блога существует раздел комментариев, где представляется возможность высказать мнение. Думается, что этим воспользуются специалисты, сведущие в теме. Обмен суждениями позволит лучше раскрыть тему и будет стимулировать участников дискуссии к собственным исследованиям. Вопросы и критические замечания автору приветствуется!

4cent.Gothic Bible

About the Book of Genesis of the Gothic Bible (4th century). A Gothic term that may have been used to refer to the ligamentum capitis femoris (LCF) of an animal and a human. See our commentary at the link: 4cent.Gothic Bible [Rus]. Quote [ Got ] Genesis 32:33 (possible term; original source lost) Translation [Eng] Genesis 32:33 The original text and English translation are currently unavailable to our project. Suggested term: … gabinda ( gabundi) … The closest analogue is in the Epistle to the Colossians 2:19 — jah ni habands haubiþ, us þammei all leik þairh gawissins jah gabindos auknando jah þeihando wahseiþ du wahstau gudis. — καὶ οὐ κρατῶν τὴν κεφαλήν , ἐξ οὗ πᾶν τὸ σῶμα διὰ τῶν ἁφῶν καὶ συνδέσμων ἐπιχορηγούμενον καὶ συμβιβαζόμενον αὔξει τὴν αὔξησιν τοῦ θεοῦ . — And not holding the Head, from which all the body by joints and bands having nourishment ministered, and knit together, increaseth with the increase of God.

The authors reported a case of open hip dislocation and documented avulsion of the ligamentum capitis femoris (LCF) from the acetabulum. The injured LCF appeared as a large cord-like structure, attached to the femoral head ( Fig. 1 ). Perhaps Hippocrates of Kos saw such an LCF in open dislocation of the hip and described it in his treatise «Mochlicus» ( 1886AdamsF ). One year later, the patient's x-ray revealed a significant narrowing of the joint space in the upper part of the hip joint ( Fig. 9 ). In our opinion, this to be a consequence of hyaline cartilage wear due to overload in the absence of LCF. In an unaffected hip joint, the width of the radiological joint space at the upper section than in the lower section ( Ossification of the LCF ). When examined one year after the injury, the patient could stand on one leg. We noticed that his body was excessively deviated towards the supporting hip joint, and the opposite half of the pelvis was elevated ( Fig. 8 ). This is a me

1875BrauneW

We present a study dedicated to the experimental investigation of the function of the ligamentum capitis femoris (LCF). Wilhelm Braune established that the LCF prevents hip supination and adduction, especially during flexion. In the conclusion of the study, the author writes: "It also remains to determine in which body movements this ligament function plays a role, as it is currently unclear why the femur requires a special fixing device…". Apparently, Wilhelm Braune did not have time to find the answer, since his outstanding monograph on LCF does not say a word ( Braune W, Fischer O. Der Gang des Menschen (1895 books.google ) . Based on our own experiments on mechanical models and research, we believe that adduction and supination of the hip, along with flexion, are observed at the beginning of the single-support period of the step. At this moment, tension occurs in the LCF, allowing to reduce the load on the upper segment of the femoral head. The LCF is also stretched in

2016ArkhipovaAS Classification of Joints with Flexible Elements.

Classification of Joints with Flexible Elements The classification of joints with flexible elements was first proposed by A.S. Arkhipova in 2016 and presented at conferences in 2016-2017 ( 2017АрхиповаАС ). Joints with flexible elements are divided by the author into detachable and non-detachable, three-axis, two-axis, and single-axis. Each can contain in various combinations one or more external and internal flexible elements - analogs of joint ligaments, including the ligamentum capitis femoris (LCF). Conditional designations of joints with flexible elements using the example of a ball joint: Detachable ball joint with an internal flexible element Non-detachable ball joint with an internal flexible element Detachable ball joint with an external flexible element Non-detachable ball joint with an external flexible element Detachable ball joint with both internal and external flexible elements Non-detachable ball joint with both internal and external flexible elements Flexible e

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 very closel

150-250Targum Jonathan

Fragments from the Targum Jonathan on Genesis. Tractate was written between about 150 - 250 in lend of Israel. The text is a combination of a translation and commentary on the book of Bereshit. The unknown compiler mentions ligamentum capitis femoris (LCF) in an animal and an episode of its damage in a human. See our commentary at the link: 150-250Targum Jonathan [Rus]. Quote 1. [Heb] Genesis. 32:33 (original source: sefaria.org ) Quote 2. [Heb] Genesis. 43:16 (original source: sefaria.org ) Translation Quote 1. [Eng] Genesis. 32:33 Therefore, the sons of Israel eat not the sinew which shrank, which is in the hollow of the thigh of cattle and of wild animals, until this day; because the Angel touched and laid hold of the hollow of the right thigh of Jakob, in the place of the sinew which shrank.

1679DiemerbroeckI

Fragments from the book Diemerbroeck I. Anatome corporis humani (1679). The author describes the pathology variants, function, topography and attachment of the ligamentum capitis femoris (LCF). The damage to the LCF in hip dislocation, symptoms and treatment are discussed. The text is similar to a paraphrase of Hegetor's work «On Causes» and Galen of Pergamon's commentary on Hippocrates' treatise «On Joints» ( 1745CocchiA ; 2020ArkhipovSV_ProlyginaIV ). Isbrand van Diemerbroeck uses many synonyms for LCF: nervus cartilaginosus, terete, teres, rotundum ligamentum, interius ligamentum. Quote p. 593. [Lat] CAPUT XIX. De Ossibus Femoris, & Cruris. Superius procesum crassum, versus coxendicis os prominentem, eique epiphyin rotundam & amplam impositam habet, sicque globosum femoris caput, valida cervice subnixum, constituit, quod cartilagine obductum in coxendicis acetabulum reconditur, in eoque duobus validis ligamentis detinetur: uno lato, crasso, & membranoso,

2014ArkhipovaAS

In 2014, at the International Olympics Space for school students, Alexandra Arkhipova presented a report on the feasibility of using joints with flexible elements in walking machines. The author was recognized as the overall winner (more details: cyclowiki.org ). The report suggested: «An important area of possible application of walking robots would be remote exploration of other planets». Ten years later, professionals from NASA began to put this idea into practice: Robot dog trains to walk on Moon in Oregon trials (more details: bbc.com ). Below we present the text of the first message about walking machines in space, the ball joint of which contains a flexible element - an analogue of the ligamentum capitis femoris (LCF).
