1844PetrequinJE

 

Fragments from the book: Pétrequin JE. Traité d'anatomie médico-chirurgicale et topographique (1844). The author discusses the role, attachment, shape, and pathological changes of the ligamentum capitis femoris (LCF). The original text in French. The text is prepared for machine translation using a service built into the blog from Google or your web browser. In some cases, we have added links to quotations about LCF available on our resource, as well as to publications posted on the Internet. The text in Russian is available at the following link: 1844PetrequinJE.  


Quote p. 704.

B. Le ligament rond ou inter- articulaire, inséré à la partie interne et inférieure de la tête , et au bord de l'échancrure ischio-pubienne du cotyle , se tend dans l'abduction de la cuisse qu'il borne, se relâche dans l'adduction, et peut permettre un déplacement incomplet en bas sans se rompre. Lorsqu'on désarticule la hanche, on n'a qu'à porter le femur dans l'abduction , et le ligament distendu se présente sous le couteau.

MM. Weber et Gerdy ont pensé que la tête était encore retenue en place par le bourrelet cotylien faisant office de soupape, et cela d'après la difficulté qu'on éprouve à séparer les deux os par des tractions verticales. L'explication n'est pas très-exacte. Je signalerai plus loin un autre moyen d'union oublié jusqu'ici.

 

Quote p. 706.

Apartir du col , la synoviale se replie sur la capsule , puis enveloppe le ligament rond , et descend dans la cavité cotyloïde tapisser le paquet celluleux qui s'y trouve. J.-L. Petit attribuait à la tuméfaction de cette masse et à l'hypersécrétion de la synovie, l'allongement qui suit la coxarthrocace au début. C'est l'opinion qui a eu le plus de faveur. On a toutefois oublié que ce paquet cellulo-adipeux est recouvert par une membrane fibreuse qui l'emprisonne et s'oppose à un grand développement. Dans les autopsies , je ne lui ai jamais trouvé un volume notable.

 

Quote p. 708.

C. La tête fémorale , plus qu'hémisphérique, appartient à un sphéroïde de 2 pouces environ (54mm) de diamètre. Sur un homme adulte j'ai trouvé 5 pouces 10 lignes (157mm) pour la circonférence , 3 pouces 2 lignes (85 mm) pour le segment de cercle supéro-inférieur , et 3 pouces 4 lignes (90mm) pour le transversal. Son volume est augmenté par le cartilage de revêtement. Elle présente en dedans et un peu en bas une dépression pour l'insertion du ligament rond. Sa forme varie ; elle est souvent aplatie dans les luxations congéniales , et celles dites spontanées.

 

Quote p. 710.

C'est au niveau de l'échancrure ischio-pubienne, laplus profonde de toutes , que le bourrelet cotylien , qui est percé d'un trou pour le passage des vaisseaux et nerfs nourriciers , se trouve le plus faible ; et cette disposition anatomique aux déplacements entraînerait leur plus grande fréquence dans ce sens , si , outre la présence des ligaments de renforcement que nous avons signalés, et celle du ligament rond qui , ici , accompagnant au loin la tête sans se rompre, sert à la brider , si , dis-je , les fonctions motrices ne poussaient plutôt dans un autre point.

 

Quote p. 715.

Les luxations congéniales présentent des phénomènes particuliers . La tête fémorale est , en général , déformée , aplatie , et moins volumineuse ; le col plus court et moins épais ; le cotyle d'ordinaire rétréci , elliptique ou triangulaire , parfois presque plane ou même effacé ; la cavité nouvelle est toujours peu cave, et se trouve en arrière et au-dessus de l'ancienne. Les cartilages sont altérés, amincis, ou incomplets ; le ligament rond allongé , et plus ou moins atrophié ; il n'est pasrare qu'il manque. La capsule fibreuse est conoïde; quelquefois épaissie et toujours allongée. La réductibilité de ces luxations a été révoquée en doute.

Vertebrates

VERTEBRATES According to the molecular clock, a specific method for dating phylogenetic events, vertebrates (Vertebrata) separated from arthropods (Arthropoda) 976±97 Ma (2004HedgesSB_ShoeJL). The latter began to dominate in species diversity with the Cambrian burst of radiation, which occurred 520 Ma (2010EdgecombeGD). This ratio in the fauna of the Earth is still preserved. Approximately 525 Ma, the phylum Chordates separated from the group of bilaterally symmetrical animals (1995ChenJY_ZhouGQ). In turn, the evolution of chordate organisms led to the formation of the first vertebrates at least 500 Ma, from which the jawed mouths 450-400 Ma descended, becoming the ancestors of the placoderms or "armored" fish (Placodermi) (1979 НаумовНП _ КарташевНН ).

  On the Role of the Ligamentum Capitis Femoris  in the Maintenance of Different Types of Erect Posture S.V. Arkhipov Keywords: ligamentum capitis femoris, ligamentum teres, ligament of head of femur, abductor muscle group, role,  function, hip joint, model, biomechanics, walk, gait cycle, single-legged stance  ABSTRACT New experimental and clinical data on the function of the ligamentum capitis femoris (LCF) and its participation in maintaining an erect posture were obtained. It was established that this anatomical element is involved in constraining the hip joint adduction and may fi x the joint in the frontal plane, turning it into an analogue of a second-class lever. In both unstrained one-support and asymmetrical two-support orthostatic postures, when the LCF is stretched and the abductor muscle group is exerted, a load equal to the body weight is evenly distributed between the upper and lower hemispheres of the caput femoris. In addition, the LCF fu...

Human Children. Retelling of Chapter 6

  Short retelling of chapter 6 of the essay: Arkhipov S.V. Human Children: The Origins of Biblical Legends from a Physician's Perspective. Joensuu: Author's Edition, 2025. [In Russian]  Chapter 6. THE GARDEN OF EDEN According to the Book of Genesis, humanity’s earliest ancestors emerged "in the garden of Eden." The text specifies that this idyllic garden was located "in Eden, toward the east." A nameless river flowed from Eden, irrigating the garden, suggesting that "Eden" encompasses a broader region, while the "garden in Eden" is a distinct, cultivated space. Genesis portrays the garden as a divine plantation, established by "Lord God," with humans tasked to tend and maintain it. The garden teemed with diverse trees, including fruit-bearing ones, and later hosted birds, wild animals, and domesticated livestock. Alongside humans, it harbored supernatural beings like cherubim (kyruvy), a serpent, and other divine entities. A s...
