In the 10th century, the distinguished Byzantine physician and philosopher Theophilus wrote that the ligament of the head of femur, ligamentum capitis femoris (LCF), "is created out of God's love for man." It is difficult to add anything to the wise man's statement, as the significance of this structure is indeed exceptionally great for the normal functioning of the hip joint, natural walking, and maintenance of vertical postures.

Like other elements of the human body, the LCF inevitably changes with age and is often injured. Its damage or elongation at the initial stage causes the appearance of pain, lameness and impaired ability to remain in an orthostatic position. In children, femoral head osteochondropathy, congenital hip dysplasia, pathological and congenital dislocation of the hip can develop. In adulthood, changes in LCF lead to severe hip joint diseases: osteoarthritis and aseptic (avascular) necrosis of the femoral head. Problems multiply with the number of years lived. Adjacent joints of the pelvis, spine, and knee joint gradually become affected. The quality of life decreases, limiting social interactions, reducing mobility, and increasing family expenses for treatment.

The disturbance of gait due to LCF injury was first described in the ancient literary monument "Bereshit” (Genesis), dating back to at least the 10th-5th centuries BC. Hippocrates wrote about this anatomical structure in the 5th-4th centuries BC, and later Heracleides of Tarentum, Hegetor, Apollonios of Kition, Rufus of Ephesus, Galen of Pergamon, Oribasius, and Theophilus Protospatharius. Over the past 3.5 millennia, humanity has learned relatively little about LCF. Until now, accurate diagnosis of its pathology and prevention have not been developed, and methods of effective treatment are unknown. The most modern operations for hip replacement do not involve the reconstruction of this structure, and arthroscopic interventions, accompanied by its damage or removal, aggravate the existing problems.

Nowadays, if you begin to limp and experience pain due to LCF pathology, the time for normal functioning of the hip joint is already numbered, its catastrophic change is inevitable. Conservative therapy is mostly palliative. Surgical procedures are, at best, useless, and at worst, crippling. The patients are doomed. Doctors are confused. Their efforts are still futile (02/04/2024).

There is still hope for doctors and patients. We see the need to conduct large-scale experimental and clinical studies, the results of which should become public domain. Our project will help: develop reliable methods for LCF reconstruction, create perfect artificial joints with ligament analogues, improve the prevention and diagnosis of pathology of the lower extremity girdle. This will increase the mobility of patients, and allow healthy people to maintain joint function. A wide field of scientific creativity opens up for researchers, and patrons have the opportunity to remain in history as sponsors of a project that can positively influence the life of all inhabitants of planet Earth without exception.

Original text:

В Х веке современной эры выдающийся византийский врач и философ Феофил написал, что связка головки бедренной кости, ligamentum capitis femoris (LCF), «создана по Божией любви к человеку». К высказыванию мудреца сложно что-либо добавить, ибо значение структуры действительно исключительно велико для нормального функционирования тазобедренного сустава, естественной ходьбы и непринужденного поддержания вертикальных поз.

Как и прочие элементы тела человека, LCF неизбежно изменяется с возрастом и зачастую травмируется. Ее повреждение или только удлинение на начальном этапе обуславливает появление боли, хромоты и нарушение способности пребывать в ортостатическом положении. У детей развивается остеохондропатия головки бедренной кости, дисплазия тазобедренного сустава и патологический вывих бедра. В зрелом возрасте изменения LCF приводят к тяжелейшим заболеваниям тазобедренного сустава: остеоартрозу и асептическому (аваскулярному) некрозу головки бедренной кости. Проблемы множатся с числом прожитых лет. Постепенно поражаются смежные сочленения таза, позвоночника, а также коленный сустав. Снижается качество жизни: ограничивается общение, уменьшается подвижность, увеличиваются расходы семьи на лечение.

Нарушение походки при повреждении LCF впервые описано в книге «Бырэйршит» (Бытие) – древнем литературном памятнике, датирующимся как минимум X-V веком до современной эры. Об этом анатомическом образовании писал Гиппократ в V-IV веке до современной эры, позднее Гераклид Тарентский, Гегетор, Аполлон Китионский, Руф Эфесский, Гален Пергамский, Орибасий и Феофил Протоспафарий. За прошедшие 3.5 тысячелетия Человечество узнало о LCF недостаточно мало. До сих пор точная диагностика ее патологии и профилактика не разработаны, а способы эффективного лечения неизвестны. Самые современные операции по эндопротезированию тазобедренного сустава не предусматривают воссоздание этой структуры, а артроскопические вмешательства, сопровождающиеся ее повреждением или удалением, усугубляют имеющиеся проблемы.

Ныне, если Вы начали хромать и испытываете боль по причине патологии LCF, время нормального функционирования тазобедренного сустава уже сочтено. Его катастрофическое изменение неизбежно. Консервативная терапия по большей части паллиативная. Хирургические процедуры в оптимистичном варианте бесполезны, а в худшем – калечащие. Пациенты обречены. Врачи в замешательстве. Предпринимаемые усилия и тех, и других пока бесперспективны (04.02.2024).

Надежда у докторов и больных все же есть. Нам видится, что необходимо проведение масштабных экспериментальных и клинических исследований, результаты которых должны стать общественным достоянием. Наш проект поможет: разработать надежные методики реконструкции LCF, создать совершенные искусственные суставы с аналогами связок, улучшить профилактику и диагностику патологии пояса нижних конечностей. Указанное повысит мобильность больных, а здоровым позволит сохранить функцию сустава. Перед исследователями открывается широкое поле научного творчества, а у меценатов появляется возможность остаться в истории спонсорами проекта, способного положительно повлиять на бытие всех без исключения жителей планеты Земля.

About the Book of Genesis of the Gothic Bible (4th century). A Gothic term that may have been used to refer to the ligamentum capitis femoris (LCF) of an animal and a human. See our commentary at the link: 4cent.Gothic Bible [Rus]. Quote [ Got ] Genesis 32:33 (possible term; original source lost) Translation [Eng] Genesis 32:33 The original text and English translation are currently unavailable to our project. Suggested term: … gabinda ( gabundi) … The closest analogue is in the Epistle to the Colossians 2:19 — jah ni habands haubiþ, us þammei all leik þairh gawissins jah gabindos auknando jah þeihando wahseiþ du wahstau gudis. — καὶ οὐ κρατῶν τὴν κεφαλήν , ἐξ οὗ πᾶν τὸ σῶμα διὰ τῶν ἁφῶν καὶ συνδέσμων ἐπιχορηγούμενον καὶ συμβιβαζόμενον αὔξει τὴν αὔξησιν τοῦ θεοῦ . — And not holding the Head, from which all the body by joints and bands having nourishment ministered, and knit together, increaseth with the increase of God.

The authors reported a case of open hip dislocation and documented avulsion of the ligamentum capitis femoris (LCF) from the acetabulum. The injured LCF appeared as a large cord-like structure, attached to the femoral head ( Fig. 1 ). Perhaps Hippocrates of Kos saw such an LCF in open dislocation of the hip and described it in his treatise «Mochlicus» ( 1886AdamsF ). One year later, the patient's x-ray revealed a significant narrowing of the joint space in the upper part of the hip joint ( Fig. 9 ). In our opinion, this to be a consequence of hyaline cartilage wear due to overload in the absence of LCF. In an unaffected hip joint, the width of the radiological joint space at the upper section than in the lower section ( Ossification of the LCF ). When examined one year after the injury, the patient could stand on one leg. We noticed that his body was excessively deviated towards the supporting hip joint, and the opposite half of the pelvis was elevated ( Fig. 8 ). This is a me

1875BrauneW

We present a study dedicated to the experimental investigation of the function of the ligamentum capitis femoris (LCF). Wilhelm Braune established that the LCF prevents hip supination and adduction, especially during flexion. In the conclusion of the study, the author writes: "It also remains to determine in which body movements this ligament function plays a role, as it is currently unclear why the femur requires a special fixing device…". Apparently, Wilhelm Braune did not have time to find the answer, since his outstanding monograph on LCF does not say a word ( Braune W, Fischer O. Der Gang des Menschen (1895 books.google ) . Based on our own experiments on mechanical models and research, we believe that adduction and supination of the hip, along with flexion, are observed at the beginning of the single-support period of the step. At this moment, tension occurs in the LCF, allowing to reduce the load on the upper segment of the femoral head. The LCF is also stretched in

2016ArkhipovaAS Classification of Joints with Flexible Elements.

Classification of Joints with Flexible Elements The classification of joints with flexible elements was first proposed by A.S. Arkhipova in 2016 and presented at conferences in 2016-2017 ( 2017АрхиповаАС ). Joints with flexible elements are divided by the author into detachable and non-detachable, three-axis, two-axis, and single-axis. Each can contain in various combinations one or more external and internal flexible elements - analogs of joint ligaments, including the ligamentum capitis femoris (LCF). Conditional designations of joints with flexible elements using the example of a ball joint: Detachable ball joint with an internal flexible element Non-detachable ball joint with an internal flexible element Detachable ball joint with an external flexible element Non-detachable ball joint with an external flexible element Detachable ball joint with both internal and external flexible elements Non-detachable ball joint with both internal and external flexible elements Flexible e

1879MorrisH

Fragments of the book Morris H. The anatomy of the joints of man (1879) dedicated to ligamentum capitis femoris (LCF). The author discusses the anatomy of the LCF and describes his experiments to study its movement. Quote p p . 318-319 The acetabulum is partly articular, partly non-articular. The articular portion is of horseshoe shape, and extends inwards from the margin, more or less. It is altogether deficient at the cotyloid notch, which corresponds with the gap of the horseshoe. It is the widest at the iliac part, where it is over one inch from without inwards; then it very gradually gets narrower along the ischium, but widens out again at the ischial end of the cotyloid notch ; forwards from the pubo-iliac suture it narrows more rapidly, and does not extend quite up to the pubic end of the cotyloid notch. At its narrowest point in an adult bone it measures half an inch in width. When coated with cartilage, and fringed round with the cotyloid ligament, it fits very closel
