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.

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.

1795LevelingHM

Fragment of the book Leveling HM. Anatomie des Menschen (1795). The author mentions ligamentum capitis femoris (LCF) using a rare synonym in German: runden Hängeband (suspensory ligament). Quote p . 258, second paragraph . Translation [Eng] The head has a strong bulge upwards which gradually decreases towards the bottom. Its position is oblique, according to the oblique position of the neck. The bulge represents only three parts of a sphere, and the whole is covered with cartilage in its fresh state. Slightly below the middle of this bulge is a strong impression from the round suspensory ligament (Lig. teres). Very clear traces indicate that it was a point of attachment.

50-135Akiva ben Joseph

Saying of Akiva ben Joseph extracted from the book Mekilta de-Rabbi Yishmael (ca. 200). Tractate was written in Israel, and interprets about a quarter of the chapters in Exodus. The rabbi mentions the ligamentum capitis femoris (LCF) of the animal. See our commentary at the link: 50-135Akiva ben Joseph [Rus]. Quote [Heb] Tractate Kaspa. 5:19 (original source: sefaria.org ) Translation Quote [Eng] Tractate Kaspa. 5:19 R. Akiva says: It need not be written (that eating meat and milk is forbidden), for it follows a fortiori, viz.: If the thigh sinew (gid hanasheh), which is not forbidden to be cooked, is forbidden to be eaten, then meat and milk, which is forbidden to be cooked, how much more so should it be forbidden to be eaten!
