The experiments were conducted on a specially designed mechatronic testing rig. The concept of the important role of the ligamentous apparatus is further illustrated by a set of demonstrative mechanical models. The...

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 ...

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.

The First Scientific Mention

  European science has known the LCF for about 2500 years. It is the most important functional connection of the hip joint. The first person to describe the LCF was Hippocrates (c. 460-370 BCE). A written mention of the LCF is found in §1 of his treatise "On the Instrument of redactions". In our opinion, a book created in the library of the Asclepeion of the island of Kos. Hippocrates did not dissection of the human body, did not operate on the hip joint, did not have a CT scan and MRI. How he could discover the LCF? In our view, it is possible that Hippocrates treated a patient with an open hip dislocation.

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 .

LCF in English Bibles

The primary source for translating the Bible into English is the Hebrew literary monument Torah. In its first part, the Book of Bereshit (32:33 ) , there is a mention of ligamentum capitis femoris (LCF), which in Hebrew is called « גיד » (gheed, gid) (1923, 2004PreussJ; 2019ArkhipovSV_SkvortsovDV; 2020ArkhipovSV_ProlyginaIV). Probably one of the earliest written translations of the Bible into Old English was made by Ælfric of Eynsham, who worked approximately between 955–1010 CE (1050Aelfric’s). In Aelfric's Anglo-Saxon Paraphrase, the Hebrew concept of « גיד » [gheed], that is, LCF, is mentioned twice in the 25th and 32nd verses of the XXXII Chapter of the Book of Genesis and is called «sine» ( Figure 1, 2 ). In Middle English, translators Nicholas of Hereford and John Wycliffe named LCF as «synwe», and in John Purvey's Bible edition - «senewe» (1850ForshallJ_MaddenF). In Bibles in Early Modern English, LCF is designated as «senow» and «senowe» (1530TyndaleW; 1535CoverdaleM; 1...

  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].

Chapter 32:33.1 -3 1.  על כן לא יאכלו בני ישראל , בני יעקב אסרוהו על עצמן לכבוד אביהם שלקה בו והם צוו לבניהם ( כמצות יהונדב בן רכב לבניו שלא ישתו יין ), ונאסר להם ולבניהם ולבני בניהם עד עולם , וכתבו משה רבינו בתורה על פי ה ', אבל לפירז " ל בסיני נצטוו וכתבה במקומו להודיע ​​ הטעם שנאסר בעבורו . 2.  גיד הנשה , ארז " ל כי נקרא כן לפי שנשה ממקומ ועלה ( ב " ר ע " ע ) כלומר נעל ונעלה על הכף שהוא דבק בו . 3. אשר על כף הירך , אינו אסור מן התורה אלא אשר על הכף בלבד אבל לא מה שלמעלה ממנו ושלמטה המנו , וכן גיד החיצון כולו אינו אסו...

The Shortest Comments on Genesis, Chap. XXXII-XXXIII

The chosen fragment records ancient views on the symptoms, mechanism, and differential diagnosis of ligamentum capitis femoris (LCF) injury. The author describes the emotional status, work capacity of the patient, circumstances, time, and place of the injury, as a physician in the modern medical record (Genesis 32:8-33:20). Further in the text, apparently, a pathoanatomical investigation is mentioned, confirming the antemortem diagnosis, place of dissection (Genesis 50:2-3), as well as the location of the burial of embalmed remains (Genesis 50:13). Our comments on chapters 32-33 are presented in the table. The quotes are based on the translation of the Book of Bereshit (Genesis) from Hebrew by Isaac Leeser (1922). The shortest comments Quotes from the original source Emotional status and the name of injured person. 32:8   Then   Jacob   was   greatly   afraid,   and   he   felt   distress...
