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.

§. 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.

The experiments were conducted on a specially designed mechatronic testing rig. The concept of the important role of the ligamentous apparatus is further illustrated by a set of demonstrative mechanical models. The...

The role of the ligamentum teres in congenital dislocation of the hip (1970). The authors proposed an analogy for the role of the ligamentum capitis femoris (LCF) as a “ball and chain control” and noted that it can spontaneously reduce congenital hip dislocation. The text in Russian is available at the following link: 1970MichaelsG_MatlesAL . [ii] Original text Quote p. 199 Many papers in the literature have implicated the ligamentum teres as a hindrance to the late open reduction of a congenitally dislocated hip. Occasionally the ligamentum teres has been reported to be absent. However, in most cases it is hypertrophied and elongated. Our present knowledge confirms the fact that congenital dislocation of t...

In the previously established procedure of anteroinferior acetabular LT reattachment in developmental dysplasia of the hip, the LT functions as a check-rein, showing promising results. However, this position of reattachment could potentially limit motion. Th...
