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!

Australopithecus afarensis

AUSTRALOPITHECUS AFARENSIS In 1735, Carl Linnaeus (1707-1778) placed humans as a species «Homo nosce te ipsum» in the order Anthropomorpha along with monkeys and sloths (1735LinneC). In a publication in 1758, the naturalist transferred humans to the order Primates (1758LinneC). Today, humans and chimpanzees are united in the tribe Hominini, as descended from a common ancestor (2001GrovesCP). It has been established that the chromosome that distinguishes humans from monkeys was formed before 4.5 Ma (2022PoszewieckaB_GambinA). The hominin subfamily Sahelanthropus tchadensis lived in the Republic of Chad (Central Africa) from 7.2±0.31 to 6.8±0.45 Ma (2008LebatardAE_BrunetM; 2012ReynoldsSC_GallagherA). Reconstruction of its musculoskeletal system showed that the creature could have been an upright bipedal primate (2005ZollikoferCP_BrunetM). Fossils of what is probably the first bipedal representative of the hominid family Orrorin tugenensis, lived 6.1-5.7 Ma and still retained adapta...

Human Children. Retelling of Chapter 5

Short retelling of chapter 5 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 5. ADAM AND EVE The Book of Genesis narrates the story of a tribe founded by Adam and Eve, described as the "mother of all living." From a genetic perspective, they are depicted as siblings, with an age difference of 18–25 years. According to the biblical epic, they formed humanity’s first family, sustaining themselves on pre-existing fruits and seeds. Their initial home was the "garden in Eden," located "in the east" relative to the narrator. The text identifies geographic markers for Eden’s location: lands like "Asshur," "Cush," and "Havilah," and rivers named "Pishon," "Gihon," "Hiddekel," and "Phrath." The narrator also notes the region’s economic value, mentioning "gold," ...

Fragments from the book Sabatier RB. Traité complet d'anatomie… T.1 (1775). The author discusses the form, anatomy, injuries, and role of the ligamentum capitis femoris (LCF). An opinion is expressed about the reasons for the absence of LCF and a link to the corresponding source is provided. 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. Quote pp. 7-8 On ne trouve de ligaments logés au dedans des aticulations, que dans celle du fémur avec le grand os innominé, & dans celle du même os avec la rotule & avec le tibia. Celui qui est renfermé dans la premiere, est appellé ligament triangulaire du fémur, parce qu'il a la figure d’un triangle; & ceux qui se voient dans la seconde sont connus sous les noms de ligaments internes de la rotule, & de ligaments croisés, parc...

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.

Human Children. Retelling of Chapter 6

Short retelling of chapter 6 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 6. THE GARDEN OF EDEN According to the Book of Genesis, humanity’s earliest ancestors emerged "in the garden of Eden." The text specifies that this idyllic garden was located "in Eden, toward the east." A nameless river flowed from Eden, irrigating the garden, suggesting that "Eden" encompasses a broader region, while the "garden in Eden" is a distinct, cultivated space. Genesis portrays the garden as a divine plantation, established by "Lord God," with humans tasked to tend and maintain it. The garden teemed with diverse trees, including fruit-bearing ones, and later hosted birds, wild animals, and domesticated livestock. Alongside humans, it harbored supernatural beings like cherubim (kyruvy), a serpent, and other divine entities. A s...
