With Irony About the Author

More than a quarter of a century ago, I asked myself the question: why do penguins and people waddle?

I studied the locomotion of people and animals, movement of machines, observed in zoos and museums, studied the structure of birds and human, experimented and analyzed, developed a mathematical apparatus. For the penguins the operation was developed: circular periacetabular osteotomy of the pelvis with rotational transposition of the proximal area of attachment of the ligament of the head of femur (ligamentum capitis femoris, ligamentum teres). A similar operation can improve the gait of some people too.

In the beginning, there was a question...

1917TrevesF_MackenzieC

Fragments from the book Treves F, Keith A, Mackenzie C. Surgical Applied Anatomy, 7th ed. (1917). The author discusses the strength and significance of the ligamentum capitis femoris (LCF) and its changes in hip dislocations and dysplasia. Quote pp. 542-543 3. THE HIP-JOINT … The manner in which the various movements at the hip are limited may be briefly expressed as follows: The limit of every natural movement is fixed by the extensibility of the muscles which surround a joint. That is readily seen at the hip-joint, for when the knee is extended, and the hamstring muscles thus tightened, flexion at the hip is limited long before the ligaments become tense. Ligaments only come into play when the muscular defence of the joint breaks down. Flexion, when the knee is bent, is limited by the contact of the soft parts of the groin. Extension, by the ilio-psoas, rectus femoris, and the ilio-femoral or Y -ligament. Abduction, by the adductor mass of muscles and the pubo-capsular l...

1857RichetA

Fragments of the book Richet A. Traité pratique d' Anatomie medico-chirurgicale (1857) are devoted to the anatomy of the ligamentum capitis femoris (LCF). The author believes that the vessels passing through the LCF are sufficient to supply blood to the femoral head. 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. Quote pp. 922-923 Articulation coxo-femorale. Cette articulation, qui appartient à la classe des énarthroses dont elle représente le type, a été l'objet de travaux importants de la part des physiologistes et des chirurgiens, et c'est aux frères Weber et à M. Malgaigne, plutôt qu'aux anatomistes purs, qu'on doit d'avoir mis en lumière un grand nombre des faits qui vont suivre et qui éclairent des questions pathologiques avant eux restées insol...

1877BrookeC

Report by Brooke C. and discussion of the article Dislocations of the Thigh: their mode of occurrence as indicated by experiments, and the Anatomy of the Hip-joint. By Henry Morris. M.A., M.B. (1877). In the discussion, Dr. Barwell remarked that: «He agreed with Mr. Morris in regarding the ligamentum teres as of little importance in the prevention of dislocation; it probably did little more than protect the vessels passing to the head of the bone. He saw a case some years ago, in which there was congenital absence of the ligamentum teres; but he had no reason for believing that the man was more liable to dislocation of the femur than other persons.» The author of the article, Henry Morris, suggested that Malgaigne «... did not attach much importance to the ligamentum teres; and believed that it had no power to hold the bone in its place.».

(original source: 1572 MontanoBA , p. 110) 32. Quá ob causam non comedunt neruú filij Israel, qui emarcuit in femore Iacob, vsq; in præsentem diem, eo quòd tetigerit neruú femoris eius, & obstupuerit. (original source: 1572 MontanoBA , p. 112) Translation [Eng] Genesis 32:25,32 25. But when he saw that he could not prevail against him, he touched the sinew of his thigh, and immediately it withered. (original source: 1572 MontanoBA , p. 110; our translation) 32. For this reason, the children of Israel do not eat the sinew that withered in Jacob's thigh to this day, because he touched the sinew of his thigh and dam...
