1586PiccolominiA

Fragments from the book Piccolomini A. Anatomicae praelectiones (1586). One of the first discussions of the biomechanics of the ligamentum capitis femoris (LCF) with a description of its shape, mechanical properties and attachment.

Quote p. 378-379.

[Lat]

De femoribus.

Hoc rotundum & magnum femoris caput, intruditur in magnum coxendicis acetabulum; a cuius medio emergit vinculum teres ac validissimum, femur cum coxendice copulans, & hanc articulationem firmissimam stabiliensis.

…

Cur ex animalibus progressiuis, alia recta, alia prona incedunt progredumtutue? Hanc varietatem efficit vatra ligamenti rotundi ac validi e capite femoris in acetabulum inserto. Nam si inserutur versus superiotem acetabuli partem, recta progrediuntur animantia, vt homo, si versus lateralem, prona incedunt, vt bos, equus. Qud sit, vt ille faciem celsam sit sortitus caelum suspicientem, menti commodiu sinseruientem; haec vero deptessam, terram despicientem, a qua dumtaxat corporis alimenta capessaant.

Translation

[Eng]

On the thigh bones.

This round and large head of the femur is inserted into the large acetabulum of the pelvis; from its middle comes a round and very strong ligament that connects the femur to the pelvis, which makes this joint very stable.

…

Why among walking animals do some move upright and others obliquely? This difference arises from the tension of a round and strong ligament inserted from the head of the thigh bone into the acetabulum. For if it is attached to the upper part of the acetabulum, animals walk upright, like a man; if to the side, they move obliquely, like a cow or a horse. As a result of this, those [animals] whose face is raised up and directed towards the sky are better adapted to mental actions than those whose face is lowered, turned towards the earth, from which alone they receive food for the body.

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. I b...

1918GrayH

Fragments from the book Gray H. Anatomy, descriptive and surgical (1918; 20th e d . ). The selected passages on the anatomy of the ligamentum capitis femoris (LCF) and color illustrations. Fig. 235. — Right hip bone. External surface. Quote p. 237 The Acetabulum (cotyloid cavity). — The acetabulum is a deep, cup-shaped, hemispherical depression, directed downward, lateralward, and forward. It is formed medially by the pubis, above by the ilium, laterally and below by the ischium; a little less than two-fifths is contributed by the ilium, a little more than two-fifths by the ischium, and the remaining fifth by the pubis. It is bounded by a prominent uneven rim, which is thick and strong above, and serves for the attachment of the glenoidal labrum (cotyloid ligament), which contracts its orifice, and deepens the surface for articulation. It presents below a deep notch, the acetabular notch, which is continuous with a circular non-articular depression, the acetabular fossa, at th...

1832MeckelJF

Fragments of the book Meckel JF. Manual of general, descriptive, and pathological anatomy (1832) dedicated to ligamentum capitis femoris (LCF). The author briefly discusses abnormalities of the LCF and its distal insertion. Quote p. 257 § 308. Among the deviations from the normal state, primitive deviations of the external form are rare, and usually attend anomalies of the other tissues. Among these we arrange, for instance, the absence of the tendons of the abdominal muscles, that of the ligaments of the vertebral column, and that of the dura mater of the brain and spinal marrow, &c., in a congenital fissure of the abdomen, of the vertebral column, and of the skull, and that of the tendons and the muscles of a finger, when the finger itself is wanting. But the fibrous organs are seldom deficient, when the other tissues with which they combine to form a part are present — for instance, the tendon alone of a muscle is rarely absent, or the tunica sclerotica, when the othe...
