According to the author, the ligamentum capitis femoris (LCF) is intended to prevent dislocations in all directions. A. Cooper discusses traumatic obturator dislocation of the hip joint and LCF injury in more detail.

Quote p. 148
Das ligamentum teres hat die Bestimmung, Luras tionen nach allen Richtungen hin zu verhindern, besonders aber nach abwärts, denn wenn die Schenkel weit ausein andergespreizt werden, wie z. B. bei'm Fechten, so würde der Kopf des linken Oberschenkelknochens in Gefahr feyn, aus seiner Gelenkhöhle zu schlüpfen, was aber durch dieses Ligament verhindert wird.	The ligamentum teres is designed to prevent dislocations in all directions, especially downwards, because when the thighs are widely abducted, such as in fencing, the head of the left femur may be at risk of slipping out of its joint socket, but this is prevented by this ligament.
Quote pp. 153-154
Man ist der irrigen Meinung gewesen, daß bei der Luration in das foramen ovale bas ligamentum teres werde, weil nach Zerschneidung des Kapselbandes am Leichname der Knochenkopf über den untern Rand Des acetabulum gedrängt werden kann, ohne das ligamentum teres zu zerreißen. Aber die Lupation in das foramen ovale ereignet sich, wenn die Schenkel weit auseinanderges fpreist werden, wobei das ligamentum teres in große Spannung fommt. Wird nun der Knochenkopf aus dem acetabulum getrieben so zerreißt das Ligament, ehe er noch gänzlich seine Gelenkhöhle verläßt.	It was erroneous to believe that there is no damage to the ligamentum teres during dislocation into the obturator foramen, because after cutting the capsular ligament on a cadaver, the bone head can be displaced beyond the lower edge of the acetabulum without tearing the ligamentum teres. However, dislocation into the obturator foramen occurs when the thighs are abducted, resulting in significant tension on the ligamentum teres. If, in this process, the bone head is forced out of the acetabulum, the ligament tears before it completely exits the joint socket.

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...

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...
