1844NelatonA

  

Fragments from the book: Nélaton A. Éléments de pathologie chirurgicale (Elements of Surgical Pathology. Vol. 1, 1844). The author believes that the ligamentum capitis femoris (LCF) does not retain the femoral head within the acetabulum, but it contains vessels that supply blood to the femoral head. 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: 1844NelatonA.  


Quote pp. 759-760.

A. Variétésanatomiques propres à la fracture intracapsulaire. Ces variétés sont relatives à la disposition des fragmens, à l'état du périoste, de la capsule séreuse, et enfin de la capsule fibreuse.

1° Fragmens. La solution de continuité peut occuper tous les points compris entre la tête fémorale et l'insertion du ligament capsulaire; lorsqu'elle est transversale on l'observe ordinairement sur la partie moyenne du col; mais elle est le plus souvent obhque, et alors on la voit en générai se diriger de haut en bas et de dedans en dehors de l'une des extrémités de la portion articulaire du col, à l'extrémité opposée; dans quelques cas exceptionnels , au lieu de cette obliquité simple on a observé sur chacun des fragmens une double obliquité d'où résultait pour l'un une configuration cunéiforme, et pour l'autre un angle rentrant. Cette disposition peut avoir pour résultat un engrènement des fragmens; alors il n'y a aucun déplacement. Lorsque les fragmens se déplacent, on voit l'inférieur se porter en haut et eu arrière, en même temps qu'il tourne sur lui-même de dedans en dehors; le premier mouvement produit un déplacement suivant l'épaisseur, et le second un déplacement suivant la direction. Le fragment supérieur reste contenu dans la cavité cotyloïde, à laquelle il est fixé, soit par la pression exercée par le fragment opposé, soit surtout par la pression atmosphérique. Le ligament rond, que la plupart des auteurs ont considéré comme retenant en position ce fragment, ne saurait en aucune manière remplir cet usage, car il s'insère en bas et en avant du rebord de la cavité cotyloïde, et ne peut par conséquent s'opposera sa chute , c'est-à-dire à son déplacement vers la partie déclive de l'articulation, L'expérimentation démontre ce fait de la manière la plus manifeste : aussitôt qu'on neutralise la pression atmosphérique eu perforant le fond de la cavité cotyloïde, ce fragment abandonne cette cavité et tombe dans l'articulation en demeurant appendu au ligament rond.

 

Quote p. 780.

La formation d'un cal osseux dans la fracture intra-capsulaire ne saurait donc être révoquée en doute; mais un fait non moins incontestable est l'absence fréquente de ce travail réparateur, que des causes multiples peuvent troubler, suspendre ou rendre entièrement impossible. Comme il est utile de les connaître, afin, s'il est possible, de les éloigner ou d'en affaiblir l'innuencc, nous les examinerons successivement; l'appréciation exacte de chacune d'elles nous permettra d'évaluer le degré de puissance que possède l'organisme pour la consolidation des fractures intra-articulaires du col du fémur, et par suite la valeur de l'opinion émise par S.-A. Cooper. Ces causes sont: 1° La vitalité moindre du fragment cotyloïdien. Ce fi'agment ne reçoit d'autres vaisseaux que les artérioles qui accompagnent le ligament rond; par conséquent il en reçoit moins qu'à l'état normal.


Quote pp. 780-781.

Entre ces deux opinions , nous croyons devoir nous prononcer pour la dernière , en nous appuyant : sur les faits de réunion osseuse assez nombreux connus dans la science; sur l'observation , qui monire que dans tous les cas ce fragment a continué de vivre : il est sans exemple, ainsi que le disait Desault , que sa mortification ait été la suite de la fracture , comme cela a été observe quelquefois pour la partie articulaire de la têlc de l'humérus; enfin sur l'anatomie : le ligament rond, dont on a longtemps cherché les fonctions, nous paraît avoir pour usage principal de protéger les vaisseaux qui se portent à la tôle du fémur; il doit être considéré comme un canal fibreux inséré par une de ses extrémités autour de l'orifice par lequel ces vaisseaux pénètrent dans l'articulation, et par l'autre autour de la dépression creusée au soimmet de la tête du fémur dans laquelle ils plongent : c'est une sorte de mésentère qui assure l'intégrité de ces vaisseaux, en supportant seul tous les efforts de traction produits par le déplacement de la tête fémorale.

Who, When, and Where Wrote the Book of Genesis?

  Who, When, and Where Wrote the Book of Genesis?  A Medical Hypothesis By Sergey V. Arkhipov, MD, PhD & Lyudmila N. Arkhipova, BSN     CONTENT [i]   Abstract [ii]   Introduction [iii]   Egyptian physician [iv]   Asian diviner [v]   Conclusion [vi]   References [vii]   Application [i]   Abstract The Book of Genesis is an example of an ancient literary text that contains important medical insights. We propose that it was written in northern Egypt in the late 17th century BCE, approximately ten years after the Minoan eruption. The protograph likely emerged from the collaboration between an Asiatic seer, who rose to the rank of an Egyptian official, and an Egyptian physician-encyclopedist. By refining its dating and authorship, this hypothesis positions Genesis as a credible source of medical and historical data, thereby enhancing its value for interdisciplinary research.

The role of the ligamentum teres in congenital dislocation of the hip (1970).
