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.

Who, When, and Where Wrote the Book of Genesis?

  Who, When, and Where Wrote the Book of Genesis?  A Medical Hypothesis By Sergey V. Arkhipov, MD, PhD & Lyudmila N. Arkhipova, BSN     CONTENT [i]   Abstract [ii]   Introduction [iii]   Egyptian physician [iv]   Asian diviner [v]   Conclusion [vi]   References [vii]   Application [i]   Abstract The Book of Genesis is an example of an ancient literary text that contains important medical insights. We propose that it was written in northern Egypt in the late 17th century BCE, approximately ten years after the Minoan eruption. The protograph likely emerged from the collaboration between an Asiatic seer, who rose to the rank of an Egyptian official, and an Egyptian physician-encyclopedist. By refining its dating and authorship, this hypothesis positions Genesis as a credible source of medical and historical data, thereby enhancing its value for interdisciplinary research.

Paradox. The necessary is needed by no one

  Post in a community for patients after arthroplasty.                                                                                                          A question for the patient community from an implant designer (if the Admin allows it). Hello everyone, I have a question regarding Total Hip Replacement (THR). As many of you know, dislocations remain a serious risk after surgery. This often happens because a prosthesis lacks the natural ligament that stabilizes a healthy joint. I have developed an experimental prosthesis designed for significantly higher stability. This anti-dislocation effect is achieved by creating an "internal ligament" within the construct. Theoretically, this would allow patients to bring th...
