Quote pp. 64-66.

De l'orang-outang, et de quelques autres espèces de singes

§. X. Le véritable Orang-Outang , c'est-à-dire , celui d'Asie , celui de Bornéo , n'est par conséquent pas le Pithèque , ou singe sans queue , que les Grecs et particulièrement Galien ont décrit. Ce n'est ni le Pongo , ni le Jocko , ni l'Orang de Tulpius , ni le Pygmée de Tyson ; c'est un animal d'une espèce particulière (*) , ainsi queje le prouverai de la manière la plus évidente par l'organe de la voix et par la charpente des os , dans les chapitres suivans , où je traiterai de chaque partie de l'animal en particulier.

 

* … la tête du fémur n'avoit point de rainure pour le ligament rond ; elle est donc faite comme celle du petit Orang , dont il est parlé au chapitre IX. En expliquant les figures4et 5de la planche XVII de maDescription anatomique d'un éléphant male , j'aurai occasion de remarquer que ce ligament manque chez ce grand quadrupède comme chez la secondeespèce de bradypus ( le didactylus )de Linnæus.

 

Quote pp. 132-133.

IX. Du fémur , du genou et dupied de l'Orang.

§. I. Latête du fémur est tout autour fort lisse et revêtue de cartilage sans aucun ligament rond, singularité qui me surprit beaucoup : c'étoit ainsi que se trouvoit conformé des deux côtés l'Orang de la Haie, comme je puis le prouver. En disséquant l'Orang que m'avoit envoyé M. Hope , j'ai vu que cette partie y étoit conformée de même. Cela estd'autant plus singulier néanmoins qu'on trouve constamment ce ligament dans quelques autres singes , et Galien, qui l'a décrit , a reconnu même que la dislocation du fémur ou son déboitement hors de la cavité cotyloïde , est fort difficile à rétablir , lorsque ce ligament est cassé. Chez les personnes boiteuses , ce ligament se détruit entièrement, et la téte du fémur se trouve , après leur mort , totalement lisse , c'est-à-dire , sans impression , ainsi que je pourrois le prouver par plus de quarante exemples.

Comme ce ligament manque naturellement à l'Orang, et que cependant cet animal meut facilement la cuisse , il doit avoir dans l'homme quelque destination particulière qui nous est inconnue encore. Quoiqu'il en soit , son absence produit une grande différence entre l'homme et l'Orang.

New publications of our resource   in 2026 The initial phase of collecting data on LCF, accumulated prior to the 20th century, is largely complete. Next, we plan to analyze and synthesize thematic information, adding data from the 20th and 21st centuries. The work will focus primarily on: prevention, diagnosis, arthroscopy, plastic surgery, and endoprosthetics.  January 05, 2026 2018YoussefAO The article describes a method for transposition of the proximal attachment of the LCF in congenital hip dislocation.   2007WengerD_OkaetR The authors demonstrated in the experiment that the strength of the LCF is sufficient to ensure early stability during hip joint reconstruction in children.

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 mode...

The role of the ligamentum teres in congenital dislocation of the hip (1970). The authors proposed an analogy for the role of the ligamentum capitis femoris (LCF) as a “ball and chain control” and noted that it can spontaneously reduce congenital hip dislocation. The text in Russian is available at the following link: 1970MichaelsG_MatlesAL . [ii]   Original text Quote p. 199 Many papers in the literature have implicated the ligamentum teres as a hindrance to the late open reduction of a congenitally dislocated hip. Occasionally the ligamentum teres has been reported to be absent. However, in most cases it is hypertrophied and elongated. Our present knowledge confirms the fact that congenital dislocation of t...

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 ...
