Catalog. Classifications of LCF Pathology

  The classifications are intended to systematize of ligamentum capitis femoris pathology and assist in the development of general approaches to its description, registration, analysis and treatment.   Keywords ligamentum capitis femoris, ligamentum teres, ligament of head of femur, hip joint, histology, pathological anatomy, pathology, trauma INTRODUCTION In Russia, the initial attempts to classify pathology of the ligamentum capitis femoris (LCF) were made by morphologists. The development of arthroscopic surgery has made it possible to identify various, previously undescribed types of LCF pathology, which prompted the development of various modern classifications based on intraoperative observations. Analysis of literature data and our own morphological observations allowed us to propose a General Classification of the Ligamentum Teres Pathology, which has the form of a collection of classifiers, as well as a Classification of Functions of the Ligamentum Teres. The ...

163-192Galen

Fragment from the treatise Galen. On anatomical procedures (Περὶ Ἀνατομικῶν Ἐγχειρήσεων, ca. 163-192). The author writes about the high resiliency and hardness of ligamentum capitis femoris (LCF), and also notes its connective function. See our commentary at the link: 163-192Galen [Rus], and  2020ArkhipovSV_ProlyginaIV . Quote [Grc] Περὶ Ἀνατομικῶν Ἐγχειρήσεων. Βιβλιον B. K εφ . ι ʹ .

  Fragments from the book David Kimchi «Radak on Genesis» (no later 1235). The treatise - commentary on the Tanakh, was written between about 1185-1235 years in French ( sefaria.org ). The author writes about the localization, purpose, and injury of the ligamentum capitis femoris (LCF, גיד), and also talks about its presence in adult animals and embryos.  See our commentary at the link:   1185- 1235David Kimchi [Rus].

BIOMECHANICS OF THE HIP JOINT WITHOUT LCF

  Biomechanics of the hip joint without LCF Do you remember the comparison of the ligamentum teres with the spring element of a cart? ( 1874SavoryWS ). An analogy could arise after reading the book Bell J. The Principles of Surgery (1801) . Most orthopedists still think so.

Edwin Smith Papyrus vis-à-vis Book of Genesis

   A correspondence has been found between the level of medical knowledge in the Edwin Smith Papyrus and the Book of Genesis. Were both works written during the same historical period? What do medical historians and Egyptologists think about this?  Based on the analysis I conducted, I believe that the protograph of the Book of Genesis was written at the end of the Second Intermediate Period in Egypt, with the collaboration of an Asian diviner and an Egyptian physician. Arguments in more detail are presented in my online article: Архипов С . В . Кто и когда впервые описал повреждение ligamentum capitis femoris ? (WHO FIRST DESCRIBED THE LIGAMENTUM CAPITIS FEMORIS INJURY AND WHEN? This article is available in Russian, and translation to your desired language can be done using a browser plugin).
