The First Publication on Prevention

 

In our opinion, the first publication on the topic of preventing of ligamentum capitis femoris (LCF) injury is the abstract of the report: “Arkhipov-Baltiysky SV. On increasing the safety of jumping from heights. Abstracts of reports of the All-Russian Conference ... “Trauma in peacetime and war” (Anapa, 2005).” This text not only holds historical significance but remains relevant for sports, armed forces, circus performers, and other extreme activities.

The online version of «О безопасности прыжков с высоты» (On the Safety of High-Altitude Jumps) was published in 2005 on the website «Морфомеханика» www.enet.ru/~archipov/ (no longer supported, archived copy), specifically in the section «Архив публикация автора» (Archive publications of the author).

Translation of the original text from Russian:

On Increasing the Safety of Jumping from Heights

S.V. Arkhipov-Baltiysky

In modern military operations and counter-terrorism activities, personnel of the armed forces and special units often have to jump from high altitudes or with a parachute. Increasing their safety will make it possible to effectively use the physical potential of personnel and maintain their combat effectiveness for a long time. 

To identify factors that may lead to damage to the hip joint and disrupt its normal functioning during jumps, we conducted experimental studies on a planar model of the hip joint. Contours of the pelvis and the proximal part of the femur were copied onto rigid cardboard and then separately cut out. The centers of the acetabulum and femoral head images were aligned and fixed with a needle. The contour of the acetabular fossa and the bottom of the femoral head fossa were connected with a thin nylon thread, simulating the LCF restricting the movement of the femoral head. 

The model simulated rotational movements in the hip joint in the frontal plane – adduction and abduction, as well as possible translational movements after removing the axis of rotation. It was observed that the LCF could limit adduction to an angle of about 30º, closing the knot of mobility, characteristic of a single-support orthostatic posture. In the position of maximum adduction, the head could not be displaced cranially, as it was pressed against the lower sector of the acetabular fossa model, thus 'unloading' the upper sector of the facies lunata acetabuli, preventing the displacement of the femoral head upwards. 

Accordingly, jumping from a height onto one leg with forced hip adduction can cause a rupture of the LCF. The consequence of this circumstance is a significant disruption of walking mechanics, an increase in its energy efficiency, overloading of the upper sections of joint surfaces, gradual wear, and the development of osteoarthritis or 'aseptic necrosis' of the femoral head. Prevention of the described pathology involves performing high-altitude jumps exclusively with support on two legs.

О ПОВЫШЕНИИ БЕЗОПАСНОСТИ ПРЫЖКОВ С ВЫСОТЫ

АРХИПОВ-БАЛТИЙСКИЙ С.В.

Полесская центральная районная больница, Полесск, Калининградская область, Россия

В современных боевых действиях и антитеррористических операциях личному составу вооруженных сил и специальных подразделений зачастую приходится совершать прыжки с большой высоты или с парашютом. Повышение их безопасности позволит эффективно использовать физический потенциал личного состава и сохранять его боеспособность длительное время.

Для уточнения факторов способных привести к повреждению тазобедренного сустава и нарушить его нормальное функционирование при прыжке, нами проведены экспериментальные исследования на плоскостной модели тазобедренного сустава. На жесткий картон скопированы, а затем раздельно вырезаны контуры таза и проксимального отдела бедра. Центры изображения вертлужной впадины и головки бедра совмещены и сколоты иглой. Контур ямки головки бедренной кости и дна ямки вертлужной впадины соединены тонкой капроновой нитью, имитирующей связку головки бедра. На модели было смоделированы вращательные движения в тазобедренном суставе во фронтальной плоскости – приведение и отведение, а также возможные поступательные движения после удаления оси вращения.

Отмечено, что связка головки бедра способна ограничить приведение до угла около 30º, замыкая узел подвижности, что характерно для одноопорной ортостатической позы. В положении максимального приведения головку невозможно было сместить в краниальном направлении, так как она оказывалась прижатой к нижнему сектору модели вертлужной впадины. Тем самым, связка головки бедра как бы, «разгружала» верхний сектор полулунной поверхности, препятствуя смещению головки бедра вверх.

Соответственно, прыжок с высоты на одну ногу с форсированным приведением бедра может обусловить разрыв связки головки бедра. Следствием этого обстоятельства является существенное нарушение механики ходьбы, повышение ее энергоемкости, происходит перегрузка верхних отделов суставных поверхностей, постепенное их истирание, с развитием артроза или «асептического некроза» головки бедра. Профилактикой описанной патологии является выполнение прыжков с высоты исключительно на обе ноги.

Dating and authorship of the Book of Genesis

  An original perspective on the dating and authorship of the Book of Genesis. This approach can reconcile all faiths, including atheists and scientists. English version of the article: https://roundligament.blogspot.com/2026/02/great-compilation-introduction.html   Abstract The Book of Genesis (Bereshith) was composed in Egypt during the 17th century BCE and reached its definitive protographic form following the Minoan eruption of Thera. This study argues that the work was the result of a collaboration between an Egyptian polymath and a distinguished scribe of Asiatic descent. By analyzing ancient texts, anatomical descriptions, archaeological data, Bronze Age cultural history, and climatic markers, this article demonstrates that the book emerged from the work of a high-ranking socio-political committee within the Egyptian House of Life. We argue that the inclusion of precise anatomical data, such as the ligamentum capitis femoris, serves as a diagnostic marker of this Egypti...

The First Conservative Treatment

  Conservative treatment of ligamentum capitis femoris (LCF) pathology is, without exaggeration, a highly complex subject. We understand how to repair LCF surgically, although we have not yet achieved significant success in this (2024). Methods of drug therapy for changes in LCF are not even discussed today. The first attempt at treating post-traumatic changes in LCF with recurrent hip dislocations was made by Galen of Pergamon (129-210/217 AD) over 19 centuries ago. In Hippocratis de articulis liber et Galeni in eum commentarius quatus (IV, 40) , he wrote: « And when mucus builds up in the joint, then the ligament [LCF] softens and weakens as a result. And it does not matter whether you call it a ligament ( σύνδεσμον ) or a connecting sinew ( νεῦρον συνδετικόν ). For those ligaments that have a rounded shape like tendons are usually called connecting sinews by anatomists. And we have already cured this kind of hip dislocation twice, and it did not dislocate again. Drying medica...

[In Russian]  Chapter 5.  ADAM AND EVE The Book of Genesis narrates the story of a tribe founded by Adam and Eve, described as the "mother of all living." From a genetic perspective, they are depicted as siblings, with an age difference of 18–25 years. According to the biblical epic, they formed humanity’s first family, sustaining themselves on pre-existing fruits and seeds. Their initial home was the "garden in Eden," located "in the east" relative to the narrator. The text identifies geographic markers for Eden’s location: lands like "Asshur," "Cush," and "Havilah," and rivers named "Pishon," "Gihon," "Hiddekel," and "Phrath." The narrator also notes the region’s economic value, mentioning "gold," ...

Human Children. Retelling of Chapter 7

  Short retelling of chapter 7 of the essay: Arkhipov S.V. Human Children: The Origins of Biblical Legends from a Physician's Perspective. Joensuu: Author's Edition, 2025. [In Russian]  Chapter 7. ABEL AND CAIN A pivotal moment in the saga of early humanity was the departure from the "Garden of Eden" to cultivate fields, with a focus on growing grains, as "bread" is mentioned earlier in Genesis. The text does not specify where Adam and Eve settled after leaving Eden, but we can infer it was a warm region with ample water for crops and livestock. This is evidenced by their sons’ occupations: Cain as a "tiller of the ground" and Abel as a "keeper of sheep." Over time, Cain and his family moved "east of Eden" to the land of "Nod," where he founded a "city"—a settlement with permanent dwellings. His descendants developed sophisticated skills: some mastered music, playing the stringed "lyre" and the ...
