Quote p. 205

Bourrelet cotyloiden. Ce bourrelet le pourtour de la cavité cotyloïde qu’il complete, en quelque sorte, dont il augmente profondeur, et dont il égalise la sinueuse et échancrée il est plus au niveau des échancrures: de la cavité cotyloïde que dans les autres points de son etendue. Il résulte de cette disposition, 1) que sinuosités du rebord cotyloïdien sont effaces; 2) que l’échancrure profonde que présente rebord en avant et en bas est convertie trou pour le passage des vaisseaux destinés tissu adipeux de l’arrière-cavité et au ligament interarticulaire.


Quote pp. 206-207

4. Ligament interarticulaire. Ce ligament naît de la dépression de la tête du femur, s’élargit, se divise en deux bandelettes qui vont se fixer aux deux bords de l échancrure cotyloïdienne.

Rien de plus variable que l’épaisseur et la force du ligament interarticulaire: tantôt il ne tient qu’à l un des bords de l’échancrure; tantôt il consiste uniquement dans quelques fibres ligamenteuses contenues dans l’épaisseur de la synoviale réfléchie; d’autres fois il n’existe qu un repli de la synoviale qui se déchire par la plus légère traction; enfin, il n’est pas très-rare de voir ce ligament manquer complétement.

5. La synoviale revêt toute la surface interne de la capsule fibreuse, les deux faces non adhérentes du bourrelet cotyloïdien, la partie du col du fémur qui est contenue dans l’articulation; elle embrasse le ligament rond, fournit un prolongement qui de ce ligament s’étend jusqu’au paquet graisseux qui existe au fond de la cavité cotyloïde, disposition qui avait fait admettre par les anatomistes anciens que le ligament rond s’insérait au fond de la cavité cotyloïde.

3 et 4. Dans les mouvements d'adduction et d'abduction, c'est un tout autre mécanisme. Ici, l'articulation est le centre des mouvements en arc de cercle qu'exécute le fémur; le rayon de ces mouvements est mesuré par une ligne étendue de la tête du fémur à l'intervalle des condyles. Dans l'abduction, la tête du fémur vient faire saillie contre la partie interne du ligament orbiculaire. Or, telle est la laxité de ce ligament et l'obliquité de la cavité cotyloïde; telle est encore la disposition du ligament interarticulaire, que ce mouvement peut être porté extrêmement loin sans déplacement et que la rencontre du bord supérieur du col du fémur et du pourtour de la cavité cotyloïde paraît scule le limiter. Mais cette rencontre peut de venir elle-même un moyen de luxation, et alors le sourcil cotyloïdien peut être regardé comme le point d'appui d'un levier du premier genre à bras inégaux, dont la puissance aurait pour levier toute la longueur du fémur, et la résistance pour levier le col du même os.

Dans l'adduction, le fémur décrit un mouvement en sens inverse de l'abduction; ce mouvement est borné par la rencontre du fémur de l'autre côté: mais, à l'aide d'une flexion légère, le mouvement d'adduction peut être porté jusqu'au croisement avec la cuisse du côté opposé. La profondeur très-considérable de la cavité cotyloïde à sa partie supérieure et externe, la force énorme du ligament orbiculaire en haut et en dehors, semblent s'opposer à tout déplacement. Mais remarquez que c'est presque toujours dans l'adduction qu'ont lieu les chutes sur les genoux, parce que l'adduction est un mouvement instinctif de conservation. Quelque peu étendu que soit le mouvement d'adduction, le ligament interarticulaire est nécessairement distendu; et il résulte de cette distension, suivant la remarque de M. Gerdy, que la tête du fémur est détachée du fond de la cavité cotyloïde par une sorte d'enroulement du ligament inter-articulaire sur cette tête, et vient appuyer contre la capsule fibreuse. On conçoit que la luxation est nécessairement précédée de la rupture du ligament interarticulaire.

The concept of the important role of the ligamentous apparatus is further illustrated by a set of demonstrative mechanical models. The...

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...

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 ...

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.

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.

1832MeckelJF

  Fragments of the book Meckel JF. Manual of general, descriptive, and pathological anatomy (1832) dedicated to ligamentum capitis femoris (LCF). The author briefly discusses abnormalities of the LCF and its distal insertion. Quote p. 257 § 308. Among the deviations from the normal state, primitive deviations of the external form are rare, and usually attend anomalies of the other tissues. Among these we arrange, for instance, the absence of the tendons of the abdominal muscles, that of the ligaments of the vertebral column, and that of the dura mater of the brain and spinal marrow, &c., in a congenital fissure of the abdomen, of the vertebral column, and of the skull, and that of the tendons and the muscles of a finger, when the finger itself is wanting. But the fibrous organs are seldom deficient, when the other tissues with which they combine to form a part are present — for instance, the tendon alone of a muscle is rarely absent, or the tunica sclerotica, when the othe...
