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!

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...

Ivanov A.A., Jacob’s Wrestling with God (1849-1858) . Depicting the circumstances and mechanism of the ligamentum capitis femoris (LCF) injury based on the description in the Book of Genesis: 25 And Jacob was left alone; and there wrestled a man with him until the breaking of the day. 26 And when he saw that he could not pre vail against him, he struck against the hollow of his thigh ; and the hollow of Jacob's thigh was put out of joint, as he was wrestling with him. … 33 Therefore do the children of Israel not eat the sinew which shrank, which is upon the hollow of the thigh, unto this day; because he struck against the hollow of Jacob's thigh on the sinew that shrank.

Original in Russian is available at the link: Нижний портал. Часть 1. below is a machine translation edited by a non-native speaker ( version dated 03/02/2025 ) . INFERIOR PORTAL FOR HIP ARTHROSCOPY: A PILOT STUDY PART 1. Background and Hypothesis Arkhipov S.V., Independent Researcher, Joensuu, Finland Abstract: The article presents, theoretically and graphically substantiates the technique of a new arthroscopic approach to the central compartment of the hip joint. It is proposed to introduce the optical system of the arthroscope from below through the acetabular notch without traction. Similar approaches were used for puncture, arthroscopy, arthrography, and arthrotomy of the hip joint. Diagnostics using the described lower portal will exclude complications caused by distraction of the leg and compression of the perineal support during surgery. CONTENTS PART 1.

Vertebrates

VERTEBRATES According to the molecular clock, a specific method for dating phylogenetic events, vertebrates (Vertebrata) separated from arthropods (Arthropoda) 976±97 Ma (2004HedgesSB_ShoeJL). The latter began to dominate in species diversity with the Cambrian burst of radiation, which occurred 520 Ma (2010EdgecombeGD). This ratio in the fauna of the Earth is still preserved. Approximately 525 Ma, the phylum Chordates separated from the group of bilaterally symmetrical animals (1995ChenJY_ZhouGQ). In turn, the evolution of chordate organisms led to the formation of the first vertebrates at least 500 Ma, from which the jawed mouths 450-400 Ma descended, becoming the ancestors of the placoderms or "armored" fish (Placodermi) (1979 НаумовНП _ КарташевНН ).

Hip disarticulation of the human

Hip disarticulation of the human Hip disarticulation of the human. Postmortem surgery with transection of the LCF in humans 15-12.5 thousand years ago. Presumably, the first postmortem arthrotomy of the hip joint with disarticulation was performed in Morocco 15.000-12.500 years ago. This is confirmed by multiple cuts on the femoral neck of a man from the burial of Taf V-18 ( Taforalt Iberomaurusian necropolis ). «T he cuts on the femoral neck were produced by severing the ligaments of the articular capsula in order to disarticulate the bone from the pelvis. There are no pelvic bones in the grave.» ( 2016MariottiV_CondemiS:Fig.2 ). We counted more than a dozen longitudinal, fairly deep cuts in the middle part of the femoral neck. Their length varies from about two to ten millimeters and occupies a surface of 1 cm along the length of the femoral neck and 2 cm in width. The mentioned cuts on the cortical plate and the absence of pelvic bones in the burial are evidence of the disarti...

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 ...
