1865LangerC

The author discusses the structure of the ligamentum capitis femoris (LCF) and notes the presence of a cavity filled with vessels and loose fiber. Karl Langer has not personally studied the LCF function and therefore speaks with caution on this topic.

The translation from German was done in collaboration with ChatGPT 3.5.

Quote p. 146
Das Ligamentum teres ist eine durch derbes Bindegewebe verstärkte Synovial - Duplicatur, welche einerseits am Foramen acetabuli, andererseits am Umbo des Kopfes befestigt ist, und einen mit lockerem Bindegewebe und Blutgefässen erfüllten Hohlraum einschliesst. Der Synovial - Ueberzug des Bandes ist eine Fortsetzung des synovialen Ueberzuges des Pfannengrundes, und die derben Faserzüge desselben, welche sich am Umbo concentriren entstehen theils vom Limbus, theils von den Knochen. Durch das Foramen acetabuli treten in den annähernd kegelförmigen Hohlraum des Bandes zahlreiche Gefässe ein, von denen einzelne in den Körper des Schambeins, andere durch Oeffnuugen im Umbo in die Epiphyse des Schenkelkopfes gelangen. Die oberflächlichen Capillaren des Synovial-Ueberzuges bilden da, avo das Bindegewebe des Bandes in den Knorpelüberzug des Kopfes übergeht, feine Schlingen. Bei Neugeborenen habe ich die in den Schenkelkopf eintretenden grösseren Gefässe nie vermisst, und selbst beim Erwachsenen einigemale injicirt. Grössere oder kleinere selten fehlende Oeffnungen im Umbo deuten darauf hin, dass die Gefässverbindung als Regel anzusehen ist. Auch das Labrum ist theilweise gefässhaltig. Befindet sich der Kopf in der Pfanne, so ist das Ligamentum teres gefaltet und in den nachgiebigen Pfannengrund eingelagert.	Ligamentum teres is a synovial duplication reinforced by rough connective tissue, which is attached on one side to the acetabular foramen, and on the other side to the apex of the head, and limits a cavity filled with loose connective tissue and blood vessels. The synovial membrane of the ligament is a continuation of the synovial membrane of the bottom of the cavity, and its coarse fibrous fibers, concentrated at the apex, extend partly from the acetabular lip, partly from the bones. Numerous vessels enter the approximately conical cavity of the ligament through the acetabular foramen, some of which enter the body of the pubis, others, through holes in the apex, enter the epiphysis of the femoral head. The superficial capillaries of the synovial membrane form thin loops at the junction of the connective tissue of the ligament with the cartilaginous cover of the head. In newborns I have never missed the larger vessels entering the head of the femur, and even in adults when giving injections. Larger or smaller openings in this area are rarely absent, indicating that a vascular connection should be considered as a rule. The acetabular lip is also partially vascular in nature. If the head is in the socket, the ligamentum teres is folded and embedded in the flexible bottom of the socket.
Quote p. 149
Das gefässreiche Ligamentum teres dürfte wohl kaum mit der Zähigkeit seiner Fasern wesentlich in den Gang des Gelenkes eingreifen.	The ligamentum teres, rich in blood supply, probably does not significantly influence joint movements due to the strength of its fibers.

Vertebrates

VERTEBRATES According to the molecular clock, a specific method for dating phylogenetic events, vertebrates (Vertebrata) separated from arthropods (Arthropoda) 976±97 Ma (2004HedgesSB_ShoeJL). The latter began to dominate in species diversity with the Cambrian burst of radiation, which occurred 520 Ma (2010EdgecombeGD). This ratio in the fauna of the Earth is still preserved. Approximately 525 Ma, the phylum Chordates separated from the group of bilaterally symmetrical animals (1995ChenJY_ZhouGQ). In turn, the evolution of chordate organisms led to the formation of the first vertebrates at least 500 Ma, from which the jawed mouths 450-400 Ma descended, becoming the ancestors of the placoderms or "armored" fish (Placodermi) (1979 НаумовНП _ КарташевНН ).

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.
