Quote pp. 263-264

§. CCCCLXXX.

Acetabularum structura, et vsus,

Sunt autem amplissima cauatam mirifice coxis adposita, vt iisdem coxae cum toto trunco diuersimode super femora moueri et inclinari possint. Quaelibet sinuositas caput femoris profundius excipiens proprie acetabulum, Gr. κοτύλῃ vocatur (§. LXXVI.), ex concursu trium ossium componitur (§. CCCCLXXVII.), et crusta cartilaginea obducitur ac augetur (§. CCCCLXVIII); defectus vero in imperfecta ipsius ora ab opposita cartilagine suppletur, et per incisuram (§. CCCCLXXXI.) vasa, a compressione libera, tutissime admittuntur. Totus denique sinus validissimo, ex supercilio eius inaequali pro deunte ligamento, firmissime cum capite ossis femoris unitur.

§. 480.

The structure of the acetabulum and its appearance,

However, there are very large cavities wonderfully placed near the hips to allow them to move and bend in various ways relative to the entire torso. Each depression in which the head of the femur is deeply embedded is called the acetabulum proper, in Greek κοτύλῃ (§. 76), consists of a connection of three bones (§. 477), is covered with a cartilaginous layer and expanded (§. 468); but there is a defect, which at the edge is filled with the opposite cartilage, and through the incision (§. 481) the vessels, free from compression, are safely passed. In the end, the entire sinus is very strong, thanks to the uneven edge, with the missing ligament, it is firmly connected to the head of the femur.

Quote p. 264

§. CCCCLXXXI.

corumque sminor in ima parte cauitas.

Quum vero anterius et lateraliter ex parte dehifcat, supercilium illius imperfectum et inaequale fit, immo sinuositas, quae in medio et versus ilia latescit, ad hiatum rursus angustatur. Cauitas minor, quam in ima parte continet, simili gaudet margine imperfecto et inaequali, ac aspera superficie, eaque non solum ligamentum teres siue planum recipit, verum etiam glandulae mucilaginosae tutissimum concedit locum, efficitque, ne tota sub motu comprimatur.

§. 481.

smaller cavity at the bottom.

Where the rupture occurs anteriorly and laterally, its [acetabulum] edge becomes incomplete and uneven, and the notch, which extends from the middle outward, narrows again to a fissure. The smaller cavity which it [the acetabulum] contains in the lower part, also has the same interrupted and uneven edge and a rough surface, which not only receives the round or flat ligament, but also provides the safest place for the mucous glands, preventing them from being completely compressed when movements.

Quote pp. 324-325

§. DLXXXVIII.

eiusque inaequalis fossa qua ligamentum teres educitur

In medio profundam et inaequalem fossam habet, ex qua ligamentum firmissimum, crassum, et elasticum educitur, quod propriae acetabuli crenae inseritur (§. CCCCLXXXI), et, vi officii, suspensorium dici meretur.

§. 588.

and its irregular fossa, through which the round ligament passes.

In the middle there is a deep and uneven fossa, from which emerges a very firm, thick and elastic ligament, which is attached to its own notch of the acetabulum (§. 481), and by its function deserves to be called suspensory.

Quote pp. 325-326

§. DXC.

Connexio capitis femoris cum acetabulo.

In commissura capitis cum collo femoris, et circulo praecipue circa basin ceruicis aspero, ligamentum vasis refertissimum, robustum, validumque capsulare, quod caput ossis femoris cum acetabulo iungit (§. CCCCLXXX), firmatur. Quo vero liberius in centro acetabuli versari, et absque vasorum, illud ingredientium (§. CCCCLXXXI.) compressione, ex glanduloso-pinguedinosis organis mucus capsam inter et caput femoris exprimi, nec, relaxato forsan articulari vinculo, os prorsus ex articulatione elabi possit; natura suspensorio prospexit ligamento (§. DLXXXVIII).

§. 590.

Connection of the head of the femur with the acetabulum.

At the junction of the head with the neck of the femur and especially around the base of the neck, there is a very dense, strong and powerful capsular ligament that connects the head of the femur with the acetabulum (§. 480) and secures it. It allows the head of the femur to move freely inside the acetabulum and without compressing the vessels entering it (§. 481), under pressure the mucus from the glandular-fatty organs is squeezed out between the acetabulum and the head of the femur, and, even if the articular ligament [capsule] weakened, the bone cannot slide completely out of the joint; is because nature has focused on the suspensory ligament (§. 588).

1898AshhurstJ

Report Ashhurst J. Tuberculosis of the hip joint (1898). The author discusses the function of the LCF as a supporting element of the body, its role in the development of deformity of the hip joint, reducing pressure and stress in the femoral head. The most notable quotes: «Of course, the whole weight of the body is not sustained by this ligament, but mostly by the head of the femur in more or less close contact with the cotyloid cavity; but this ligament, I believe, serves to diminish the pressure of the pelvis upon the head of the bone, and to lessen strain. The position of the ligamentum teres is like that of the old-fasioned leather springs which used to be found in stage- coaches, the body of the coach being balanced upon two broad strong bands of leather. The pelvis is to a certain extent similarly balanced upon these ligaments on either side, which are attached to the heads of the thigh- bones, and then pass down to the lower edges of the cotyloid cavities.

The Emergence of Life

THE EMERGENCE OF LIFE According to our definition, life is a way of existence of material objects capable of regulating the level of average daily mechanical stress and reproducing similar entities (2004 Архипов - БалтийскийСВ ). As can be seen, in the given definition there is no reference to protein bodies and organic compounds. Life as a special qualitative state of matter is fundamentally possible not only on the basis of carbon. At the same time, living systems with a different chemistry are unknown, as are extraterrestrial beings. The oldest potentially biogenic carbon on our planet appeared 4.10±0.01 billion years ago, and the simplest living beings appeared 4.1-3.8 billion years ago (2015BellEA_MaoWL). The split of single-celled, anucleate forms of prokaryotes (Procaryota) into bacteria (Eubacteria) and archaea (Archaebacteria) occurred about 4.0 billion years ago (2002HedgesSB). The oldest stromatolites, which are the remains of cyanobacterial communities (Cyanobacteria), bega...

The First Animals

THE FIRST ANIMALS According to molecular clock data, the separation of the Animal Kingdom from the Plant Kingdom occurred 1609±60 Ma (2004HedgesSB_ShoeJL). Molecular estimates indicate that the last common ancestor of multicellular representatives of the fauna (Metazoa) was Neoproterozoic, most likely younger than 800 million years (2015PisaniD_LiuAG). Biomarkers of metazoan living systems identified in sedimentary deposits indicate their presence in the seas since the Cryogenian period (2018ZumbergeJA_SummonsRE), which began around approximately 720 Ma (2023CohenKM_CarN). Multicellular animals were part of early Ediacaran ecosystems and are found below layers dated to 632.5 ± 0.5 Ma (2007Yin_LHuJ). The oldest fossil of a multicellular organism resembling a sponge (Porifera) is about 600 Ma (2015YinZ_TafforeauP). The last Neoproterozoic glaciation (about 582 Ma) coincides with the appearance of complex organisms in the fossil record (2007BowringSA_AllenPA). Ev...

The First Scientific Mention

European science has known the LCF for about 2500 years. It is the most important functional connection of the hip joint. The first person to describe the LCF was Hippocrates (c. 460-370 BCE). A written mention of the LCF is found in §1 of his treatise "On the Instrument of redactions". In our opinion, a book created in the library of the Asclepeion of the island of Kos. Hippocrates did not dissection of the human body, did not operate on the hip joint, did not have a CT scan and MRI. How he could discover the LCF? In our view, it is possible that Hippocrates treated a patient with an open hip dislocation.
