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...

Edwin Smith Papyrus vis-à-vis Book of Genesis

A correspondence has been found between the level of medical knowledge in the Edwin Smith Papyrus and the Book of Genesis. Were both works written during the same historical period? What do medical historians and Egyptologists think about this? Based on the analysis I conducted, I believe that the protograph of the Book of Genesis was written at the end of the Second Intermediate Period in Egypt, with the collaboration of an Asian diviner and an Egyptian physician. Arguments in more detail are presented in my online article: Архипов С . В . Кто и когда впервые описал повреждение ligamentum capitis femoris ? (WHO FIRST DESCRIBED THE LIGAMENTUM CAPITIS FEMORIS INJURY AND WHEN? This article is available in Russian, and translation to your desired language can be done using a browser plugin).

Key Role of the LCF

In the experiments conducted on the pelvis-femur-muscle-ligaments model, we found that when the contralateral pelvic drop occurs, the ligament of the head of femur become maximally tense; simultaneously, there is relaxation and lengthening of the gluteus medius muscle; the pelvis spontaneously rotates towards the stance limb (forward), and the load on the hip joint decreases. Thanks to the functioning of the ligament of the head of femur the walking is smooth, rhythmic, and energy-efficient.

ZOOLOGY AND PALEONTOLOGY

ZOOLOGY AND PALEONTOLOGY (Information on the presence in existing and extinct animals... ) LCF of Pithecanthropus In the hip joint of Pithecanthropus (Pithecanthropus erectus, Homo erectus 2.12-0.43 Ma), there was a LCF. LCF of Australopithecus The Australopithecus afarensis (3.2 Ma) had a ligament of the head of femur. 1802CamperP The author discusses the absence and unknown role of the LCF in the elephant and some monkeys. 1803CamperP The author discusses the absence and unknown role of LCF in the orangutan, elephant, and sloth. 1824MeckelJF The author notes the absence of LCF in orangutans, three-toed sloths and turtles. 1835OwenR The author discusses the absence of the LCF in chimpanzees, orangutans and some other mammals. 1851BarkowHCL The author briefly describes LCF in the tiger and llama. 1864MacalisterA LCF has been observed in ostrich and is noted to be strength. 1869MivartG ...
