Quote p. 301

§. CCCCXXVIII.

…Cavum acetabuli hemisphaericum non ubique cartilagine obducitur, sed ad tertiam fere partem nudum conspicitur, ideoque pars, cartilaginoso tegmine obducta, lunatam figuram refert. Mediae huius regionis parti impressio aspera imponitur, quae ligamentum, quod caput ossis femoris devincit, excipit. Reliquam cavi acetabuli partem, cartilagine nudam, tenuem, non nihil planiorem pinguedo explet.

Quote p. 373

§. DXXXXIIII.

…Caput cartilagine obductum, hemisphaerio non nihil maius, ambitum undulatum habet, ita, ut in superiore et posteriore parte in angulum porrigatur, ideoque ambitui acetabuli respondeat. In media fere capitis parte, non nihil tamen inferiora et interiora versus, aspera, cartilaginoso tegmine nudata fovea, ligamentum teres excipiens, ponitur. Media hemisphaerii pars axin colli tangit.

Quote pp. 377-378

§. DLII.

Os femoris inter omnia artuum inferiorum ossa plurimis varietatibus subiectum videtur. Nonnumquam valde longum est, sed tenue; nonnumquam vero longum et plenum simul. Rarissime fovea ligamenti teretis abest. *)

Quote p. 301

§. CCCCXXVIII.

... The cavity of the acetabulum has a hemispherical shape and is not covered with cartilage everywhere; about a third of it remains bare, so the part covered with cartilage has a crescent shape. In the central part of this area is a rough depression that receives the ligament that binds the head of the femur. The rest of the acetabulum cavity, not covered by cartilage, is filled with a thin layer of fat, which slightly smoothes the surface.

Quote p. 373

§. DXXXXIII.

... The head of the femur, covered with cartilage, is slightly larger than a hemisphere and has a wavy edge, so that in the upper and posterior parts it forms an angle that corresponds to the contour of the acetabulum. Almost in the center of the head, but somewhat lower and closer to the inside, there is a rough fossa, not covered with cartilage, to which the round ligament is attached. The central part of the hemisphere touches the axis of the femoral neck.

Quote pp. 377-378

§. DLII.

Of all the bones of the lower extremities, the femur is subject to the greatest number of variations. Sometimes it is very long, but thin; sometimes, on the contrary, it is long and thick at the same time. Very rarely the fossa for the round ligament is missing. *)

*) GENGA Anatom. chir. Romae 1687. SALZMANN Decas Obs. anat. Arg. 1725. 4. recus. in HALLERI Diss. select. T.VI. p. 694. In femurs affected by arthritis, the round ligament and its trace on the bone are often lost, as I have repeatedly observed. see also BLUMENBACH medicinische Bibliothek, 3 Band.

On the Role of the Ligamentum Capitis Femoris in the Maintenance of Different Types of Erect Posture S.V. Arkhipov Keywords: ligamentum capitis femoris, ligamentum teres, ligament of head of femur, abductor muscle group, role, function, hip joint, model, biomechanics, walk, gait cycle, single-legged stance ABSTRACT New experimental and clinical data on the function of the ligamentum capitis femoris (LCF) and its participation in maintaining an erect posture were obtained. It was established that this anatomical element is involved in constraining the hip joint adduction and may ﬁ x the joint in the frontal plane, turning it into an analogue of a second-class lever. In both unstrained one-support and asymmetrical two-support orthostatic postures, when the LCF is stretched and the abductor muscle group is exerted, a load equal to the body weight is evenly distributed between the upper and lower hemispheres of the caput femoris. In addition, the LCF fu...

INFERIOR PORTAL FOR HIP ARTHROSCOPY: A PILOT STUDY PART 1. Background and Hypothesis Arkhipov S.V., Independent Researcher, Joensuu, Finland Abstract: The article presents, theoretically and graphically substantiates the technique of a new arthroscopic approach to the central compartment of the hip joint. It is proposed to introduce the optical system of the arthroscope from below through the acetabular notch without traction. Similar approaches were used for puncture, arthroscopy, arthrography, and arthrotomy of the hip joint. Diagnostics using the described lower portal will exclude complications caused by distraction of the leg and compression of the perineal support during surgery. CONTENTS PART 1.

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 ).
