Catalog. Classifications of LCF Pathology

The classifications are intended to systematize of ligamentum capitis femoris pathology and assist in the development of general approaches to its description, registration, analysis and treatment. Keywords ligamentum capitis femoris, ligamentum teres, ligament of head of femur, hip joint, histology, pathological anatomy, pathology, trauma INTRODUCTION In Russia, the initial attempts to classify pathology of the ligamentum capitis femoris (LCF) were made by morphologists. The development of arthroscopic surgery has made it possible to identify various, previously undescribed types of LCF pathology, which prompted the development of various modern classifications based on intraoperative observations. Analysis of literature data and our own morphological observations allowed us to propose a General Classification of the Ligamentum Teres Pathology, which has the form of a collection of classifiers, as well as a Classification of Functions of the Ligamentum Teres. The ...

The First Scientific Mention

European science has known the LCF for about 2500 years. It is the most important functional connection of the hip joint. The first person to describe the LCF was Hippocrates (c. 460-370 BCE). A written mention of the LCF is found in §1 of his treatise "On the Instrument of redactions". In our opinion, a book created in the library of the Asclepeion of the island of Kos. Hippocrates did not dissection of the human body, did not operate on the hip joint, did not have a CT scan and MRI. How he could discover the LCF? In our view, it is possible that Hippocrates treated a patient with an open hip dislocation.

BIOMECHANICS OF THE HIP JOINT WITHOUT LCF

Biomechanics of the hip joint without LCF Do you remember the comparison of the ligamentum teres with the spring element of a cart? ( 1874SavoryWS ). An analogy could arise after reading the book Bell J. The Principles of Surgery (1801) . Most orthopedists still think so.

The First Open Reconstruction

The first open reconstruction of the ligamentum capitis femoris (LCF) was performed in 1926 by Ernest William Hey Groves (1872-1944) (1927Hey-GrovesEW). The surgery was proposed for the treatment of congenital hip dislocation in children. Later, in 1928, regarding this pathology, he noted: «Congential dislocation of the hip is a deformity which is mysterious in its origin, insidious in its course and relentless in its final crippling results» (quoted from 1983RatliffAH). In the early 20th century, a pioneer in orthopedic surgery realized that the LCF played a crucial role in the development of this pathology and developed a technique for its reconstruction.

1747PlatnerJZ

Fragments of the book by J.Z. Platner « Institutiones Chirurgiae rationalis ...» (1747) with mention of ligamentum capitis femoris (LCF). The author describes the LCF as a durable structure that can be damaged by traumatic hip dislocations and also become pathologically altered: weakened, elongated, and disappear. The text is prepared for machine translation using a service built into the blog from Google or your web browser. In some cases, we have added links to quotations about LCF available on our resource, as well as to publications posted on the Internet. Quote p p . 432-433 §. 1192. Femur parte sua suprema habet magnum teretemque processum, qui oblique ad os coxæ procedit, quem cervicem appellant. Hæc cervix, intus rara & cavernosa, desinit in magnum & rotundissimum caput, cartilagine etiam mollitum, quod in sinum rotundum coxæ conjicitur.

The Big Bang

The Big Bang The maximum age of the observable Universe, established by measuring the anisotropy of the cosmic microwave background, is 13.801±0.024 billion years. (2020AghanimN_RoudierG). The relic stages of the creation of the World are only approxim ately understood by theoretical physicists. The development of matter into molecules, as well as the start of time, is logically described by the Big Bang theory and the concept of the expansion of space (2012HawkingS). It is impossible to imagine the Universe before its expansion from some homogeneous space or an infinitesimal grain. The reason for this is the «inner cosmic oblivion» of the previous state (2007BojowaldM). In our opinion, before that there was a black, cold, motionless Peace. Accordingly, before the mark of 13.8 billion years ago, the search for evidence of ligamentum capitis femoris (LCF) is futile anywhere in the Universe. One second after the Big Bang, the Universe consisted of light and elementary particles hea...

280-352Rava

Sayings of Rava extracted from the tractates Chullin and Horayot (Babylonian Talmud). Babylonian Talmud was written between about 450 - 550 in present-day Iraq (formerly Babylonia). The rabbi identifies the location and distal attachment site of the ligamentum capitis femoris (LCF) and demonstrates knowledge of its function. See our commentary at the link: 280-352Rava [Rus]. Quote 1. [Heb] Chullin 54b3 (original source: sefaria.org ) Quote 2. [Heb] Chullin 91a12 (original source: sefaria.org ) Quote 3. [Heb] Horayot 12a:16 (original source: sefaria.org ) Translation Quote 1. [Eng] Chullin 54b3 The Gemara addresses the matter itself: Rav Mattana says: This head of the femur that was completely dislocated renders the animal a tereifa. And Rava said: The animal is kosher, but if its sinew holding the bone in place is cut, it is a tereifa. The Gemara concludes: And the halakha is: Even if the sinew is cut, the animal is still kosher...

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...
