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.

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.

1878MarshallJ

Fragments from the book Marshall J. Anatomy for artists (1878). The author discusses the anatomy and briefly the role of the ligamentum capitis femoris (LCF): «… checks adduction of the thigh, or a sinking down of the pelvis upon the opposite side, and, possibly, also limits the reciprocal, horizontal rotatory movements of the femur and the pelvis on each other» . Quote p. 65 The head of the femur is almost entirely received into the acetabulum, a deep socket of the hip-bone, thus forming the largest and most complete ball-and- socket joint in the body. At a point on the inner side of the head of the femur, a little below and also behind its centre, is a small rough, bifid , depression, for the attachment of the ligamentum teres of the hip-joint. Opposite this point, the head of the bone is, however, more prominent than elsewhere, and corresponds with a non- articular depressed portion of the acetabulum. Quote p. 68 The ligamentum teres, which is attached by one en...

Article by Walmsley T. A note on the retinacula of Weitbrecht (1916). The author discusses the embryonic development and relationships of the ligamentum capitis femoris (LCF) in humans and animals. A NOTE ON THE RETINACULA OF WEITBRECHT. By THOMAS WALMSLEY, M.B., Senior Demonstrator in Anatomy, University of Glasgow. The synovial membrane of the hip-joint is in extent and attachment similar to that of other diarthroses, but the retinacula of Weitbrecht (or ligaments of Stanley) lend to it a special interest. These retinacula are readily recognized on the interior of the capsule as flattened bands passing inwards towards the margin of the head of the femur from the attachment of the peripheral capsule. The following description of their constitution may be selected as expressive of current opinion. The retinacula are arranged in three groups, superior, middle, and inferior: structurally, they are synovial covered capsular reflections: morphologic...

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.

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.

The author describes his own experiments on the hip joint and mentions the ligamentum capitis femoris (LCF). Edmund Rose noted that the LCF allowed the femoral head to be removed from the acetabulum more than 1½ inches (38.1 mm).
