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,

Sergey Arkhipov

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!

1801BellJ

  Selected fragments of the book Bell J. The Principles of Surgery (1801). The author discusses hip injuries and the mechanism of ligamentum capitis femoris (LCF) injury. Bell's drawing and reasoning probably led 1823GerdyPN  to consider the role of LCF tension in hip dislocation.   Quote pp. 523-524 The acetabulum or socket for the thigh bone is formed in the centre of the greatest and firmest bone of the pelvis, named os innominatum, from its irregular shape. It is in the adult the largest and firmest bone of the pelvis, but in the child it is formed of three distinct bones, the Ilium, Ischium, and Pubis. These are joined by an intermediate cartilage, and are easily separated into distinct bones. At an early age this cartilage is prominent, and somewhat of a triangular form. The cartilage is ossified in the adult, and it being ossified, becomes more prominent, and makes a high triangular projection in the centre of the socket; this prominence gives a firmer connexio...
