BLOG MOTTO

 

The ligament of the head of femur, called ligamentum capitis femoris (LCF) in Latin, is the most controversial and least studied anatomical structure in vertebrates. The authoritative Russian biomechanist Professor D.V. Skvortsov noted that its “function is not obvious,” and it is all the more interesting to find out what its significance and why it is so difficult to treat the developed changes. The author has dedicated over three decades to studying and contemplating LCF. The Blogger platform has provided a convenient avenue to share accumulated information and thoughts.

The motto of the project: “By collecting all available knowledge about the femoral head ligament, we are clarifying its role.”

A clear understanding of the significance and functioning of LCF will enable the development of new effective technologies, quality services and improved implants, as well as decipher the pathogenesis of a number of hip diseases. We expect that this will improve the results of treatment, diagnosis, and prevention of hip pathology, preserve mobility, and improve the quality of life for people and pets. According to our plan, the blog will contribute to the acquisition of new knowledge, and will serve as an information foundation for further research in the field of medicine, veterinary medicine, biology, paleontology, and robotics.

Our resource will provide up-to-date information about LCF to specialists who, by the nature of their work, “come into contact” with hip joints. The project is addressed to professional scientists, teachers, physicians, veterinarians, biomechanists, biologists, morphologists, paleontologists, anthropologists, sports trainers and roboticists. For students, a blog will help broaden their horizons, assist in deciding on a specialization, and for some, choose a path in life.

With sincere respect to you,

Sergey Arkhipov

Связка головки бедренной кости, на латыни именуемая ligamentum capitis femoris (LCF), – наименее изученная и пока самая противоречивая анатомическая структура позвоночных. Авторитетный российский биомеханик профессор Д. В. Скворцов отметил, что ее «функция неочевидна», и тем интереснее узнать, зачем она нужна, как возникла, почему столь затруднительно лечение развившихся изменений. Автор изучал и размышлял о LCF свыше трех десятилетий. Платформа Blogger предоставила удобную возможность поделиться накопленной информацией и мыслями.

Девиз проекта: «Собирая все доступные знания о связке головки бедра, уточнять значение».

Ясное понимание роли и функционирования LCF позволит: разработать новые эффективные технологии, совершенные продукты и качественные услуги, а также расшифровать патогенез ряда заболеваний тазобедренного сустава. Мы ожидаем, что это улучшит результаты лечения, диагностики и профилактики патологии тазобедренного сустава, сохранит мобильность, повысит качество жизни людей и домашних животных. По нашему замыслу, блог поспособствует обретению нового знания, создав информационный фундамент дальнейших исследований в области медицины, ветеринарии, биологии, палеонтологии, робототехники. Наш ресурс будет снабжать актуальными сведениями о LCF специалистов, которые по роду своей деятельности «соприкасаются» с тазобедренными суставами. Проект адресован профессиональным ученым, преподавателям, врачам, ветеринарам, биомеханикам, биологам, морфологам, палеонтологам, антропологам, спортивным тренерам и робототехникам. Учащимся блог поможет расширить кругозор, определиться в специализации, а кому-то и в выборе жизненного пути.

1910SuttonHA_DrinkerCK

  Fragments from the book Sutton HA, Drinker CK. Osteology and syndesmology (1910). The selected fragments discuss the anatomy and topography of the ligament of the femoral head (LCF). According to the authors, this structure has low strength, but Galen of Pergamon (2-3rd cent.) described it as «the strongest» ( 1829KühnCG ). [Eng] Quote 1. p. 76 . The Cotyloid Lig't., or Cartilage, surmounts the edge of the Acetabulum except where it is broken by the Notch. This ligament simply deepens the cavity. The centre of the Acetabulum, by a rough area, the Cotyloid Fossa, attaches the Ligamentum Teres. Quote 2. p. 79. Head. Slightly more than a half sphere in shape. An articular surface for the Acetabulum occupies it, except at a fossa which attaches the Ligamentum Teres. Quote 3. p. 86. Two connect the bones. They are: 1. Ligamentum Teres: — Weak. Passes between the centre of the Acetabulum and the oval fossa upon the Head of the Femur. It lies outside the synovial membrane. External link...

Localization of LCF Pathology

  Version : 20240418 Localization of LCF pathology is classified based on the anatomical-topographical principle. It is assumed that the LCF does not end near the attachment site but penetrates into it. LOCALIZATION OF LCF PATHOLOGY 1. Middle part 2. Distal end 3. Proximal end 4. Distal attachment area 5. Proximal attachment area 6. Medial surface 7. Lateral surface 8. Anterior edge 9. Posterior edge 10. Transsynovial 11. Subsynovial 12. Total Lesion The medial surface faces the bottom of the acetabulum. The lateral surface faces the femoral head. Transsynovial pathology implies changes including or only involving the synovial membrane. Subsynovial pathology is localized exclusively beneath the synovial membrane of LCF. Pathology can involve multiple parts of LCF, for example, damage to the distal end and proximal attachment area in a transacetabular fracture.   The distal part of LCF attaches directly to the bone of fovea capitis femoris. Along...
