22cent.bcBaqetI

Groups of wrestlers are depicted on the walls of tomb BH29, belonging to Baqet I – a contemporary of the pharaohs of the early 11th Dynasty (frescoes, Beni Hasan, Egypt). The images show wrestling scenes and the circumstances under which injuries to the hip joint – including the ligamentum capitis femoris (LCF) – might occur. These frescoes appear to have served as the basis for the description of a wrestling match found in the Book of Genesis: 25 And Ja cob was left alone; and there wrestled a man with him until the breaking of the day. 26 And when he saw that he could not pre vail against him, he struck against the hollow of his thigh ; and the hollow of Jacob's thigh was put out of joint, as he was wrestling with him. … 33 Therefore do the children of Israel not eat the sinew which shrank, which is upon the hollow of the thigh, unto this day; because he struck against the hollow of Jacob's thigh on the sinew that shrank.

This required deep knowledge in agriculture, crafts, trade, geography, meteorology, as well as an understanding of various dialects, political trends, and tribal relations. However, nothing is known about Jacob's education. He was born near the well of "Beer-Lahai-Roi", which was located "in the Negeb" (Gen. 24:62, 25:11). Here, in the arid terrain in the south ...

Through his questioning, he helped the patient independently comprehend what had transpired. In parallel, he himself came to understand the cause-and-effect relationships governing the development of the pathological...

1892PoirierPJ

Fragments from the book Poirier P.J. Traité d'anatomie humaine. T.1 (1892). The selected passages summarized the basic information about ligamentum capitis femoris (LCF) obtained by the end of the 19th century. The author provides data on the strength of LCF obtained in cooperation with Paul Gilis. 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. 653-666 § II. — ARTICULATION COXO-FÉMORALE.

THE OLDEST LCF

The very first four-legged animal, the lobe-finned fish Tiktaalik roseae, lived about 375 million years ago. Based on indirect evidence (paired notches of the acetabulum), we believe that in the hip joint it had two ligaments of the head of femur, in Latin called ligamentum capitis femoris (LCF). A similar anatomy of the hip joint is preserved in the salamander. Illustration Tiktaalik roseae is the first animal to have a LCF A) 3D model of the right pelvic bone of the fish Tiktaalik roseae (fragment of a screenshot: media.hhmi.org ), where we depicted the dissected anterior LCF (lig.cap.fem.ant.) and posterior LCF (lig.cap.fem.post.), that are attached to the corresponding notches of the acetabulum ( inc.ac.ant. & inc.ac.post.). Below the pelvis is a photograph of our model of the Tiktaalik roseae femur with fragments of two LCFs (a fossil femur of Tiktaalik roseae has not yet been discovered). B) View of a salamander femur with a proximal fragment of the ilia...
