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.

1884SuttonJB

Fragments from the article Sutton JB. Ligaments: Their Nature and Morphology (1884). The author discovered that in the ostrich the ligamentum capitis femoris (LCF) was not continuous with the ambiens muscle, but with a muscular slip which ran parallel with the-muscle, and ended in the adductor mass. This publication develops the theme of article 1883SuttonJB . Quote pp. 228-229 I must now pass on to consider certain ligaments of the appendicular skeleton, commencing with some additional remarks on the ligamentum teres. The Journal of Anatomy and Physiology, vol. xvii January 1883, contains a short article on the ligamentum teres, in which I have endeavoured to point out that many ligaments are the tender of muscles which were originally in relation with the joint; but the parent muscle has either formed new attachments or become obsolete, whilst the tendon remains as a passive element in the articulation. In addition to the ligamentum teres the following structures ...

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...
