1610RiolanJ

Fragments from the book Riolan J. Ioannis Riolani ambiani medici parisiensis, viri clarissimi opera omnia… (1610). The author discusses the location, function and attachment of the ligamentum capitis femoris (LCF). The following synonyms are mentioned for LCF: terete & validissimo ligamento, neruus and ischion. The term «ischion» for LCF was also used by Alessandro Benedetti (1527BenedettiA). Probably, this synonym in Greek «Ισχίου» was first used for LCF by Rufus of Ephesus (1879DarenbergCV_RuelleCE; 2020ArkhipovSV_ProlyginaIV). His contemporary, Julius Pollux, uses a similar term (1706PolluxJ). In turn, this fragment, telling about LCF, was quoted by Giovanni Filippo Ingrassia (1603IngrassiaeIP).

ANATOMY

Of the Ilium, Ischium, and Pubis. Chapter XLIV.

… From these three parts is formed the large acetabulum, which is called la boétte [the chamber / cavity]. Into it is inserted the head of the femur, connected by a round and very strong ligament. The edges of this cavity are sharp and rough on the outside, where a very strong ligament begins, which surrounds the whole joint (which Caelius Aurelianus calls a "vertebra"). …

Of the femur. Chapter XLV.

… First of all, it should be noted that the head is round and articulates with the hip joint, which Hippocrates in his book "On the Nature of Bones" calls the epiphysis. From it comes the nerve that connects and strengthens the femur in the acetabulum. ...

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...

Fragments from the book Fabricius JA. Bibliothecae Graecae volume duodecimum (1724). The author quotes the Byzantine physician Theophilus Protospatharius, who supposedly lived between the 7th and 10th centuries. Selected passages provide views on the normal anatomy of the ligamentum capitis femoris (LCF) and its inherent connective function. [Grc] θεοφιλος ο Πρωτοσπαθάριος .

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...
