1794(a)SommerringT

Fragments from the book Soemmerring ST. De Corporis Humani Fabrica. T.1. (1794). The author describes the attachment and role ligamentum capitis femoris (LCF). Cases of its absence are mentioned, in particular in osteoarthritis. We have added links to quotations about LCF available on our resource, as well as to publications posted on the Internet. There is a known version of the treatise in German: 1791SoemmerringST.

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.

§. 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.

§. 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.

According to the author, the ligamentum capitis femoris (LCF) is a tendon of the pectineus muscle, separated from it in consequence of skeletal modifications. THE LIGAMENTUM TERES By J. B. SUTTON, Demonstrator of Anatomy, Middlesex Hospital. (PLATE VIII.) The round ligament of the coxo-femoral articulation has long been an anatomical puzzle, consequently many diverse notions exist concerning it. Some anatomists ascribe to this hollow band of fibrous tissue very important functions in the mechanism of the hip-joint; others deprive it of all glory, simply assigning to it the menial duty of conveying blood-vessels to the head of the femur. Certain authors content themselves with a brief description of its attachments; others give elaborate and detailed accounts, extending over several pages, of its anatomy and supposed function. My object in the present communication is to show that this singular ligament is nothing more than the tendon of the pectineus muscle, sepa...

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 authors saw that in an upright position, the LCF is vertical, taut, and apparently serves to support the weight of the body on the head of the femur, especially due to the two anterior and posterior parts, which are quite strong.
