ABOUT THE AUTHOR

The blog is managed and administered by Sergey Vasilyevich Arkhipov, a candidate of medical sciences, general surgeon, and orthopedic traumatologist (orthopedic surgeon) of the highest qualification, as well as a medical expert.

The author graduated from the State Medical Institute in 1992 (Smolensk, Russia) and defended his dissertation at the Russian University of Friendship of Peoples (Moscow). He studied at the Central Institute of Traumatology and Orthopedics (Moscow) and the Russian Research Institute of Traumatology and Orthopedics (St. Petersburg). He also had internships at the Hannover Medical School (Medizinischen Hochschule Hannover).

Sergey Arkhipov has experience working in the orthopedic department of a regional clinical hospital, trauma departments of major city medical institutions, a regional burn center, a trauma center, a surgical department of a district hospital, state polyclinics, and private medical clinics. He has been involved in research activities, serving as a practicing physician, department head, deputy chief physician for clinical-expert work, consultant in the field of traumatology and orthopedics, medical expert, and senior researcher at the "Biomechanics and Mechatronics" laboratory (N.I. Pirogov Russian National Research Medical University). Sergey Arkhipov worked in the laboratory of "Clinical Physiology and Biomechanics" at the Federal State Budgetary Institution National Medical Research Center named after N.N. Priorov (Central Institute of Traumatology and Orthopedics). Currently, he is an independent scientist.

He has been awarded the Honorary Certificate of the Ministry of Health of the Russian Federation, the Gratitude of the Mayor of Moscow, certificates of Heads of Administrations, and chief physicians of medical institutions. Sergey Arkhipov was the winner of the regional television contest "Person of the Year – 2004" in the category of "Discovery" and a laureate of the contest "Man – Event – Time." in 2001.

The author created a series of original mechanical models of the human hip joint, designed a quadripedipulatory zoomorphic walking platform, and a prototype of an anthropomorphic walking mechanism. He proposed a family of artificial joints with analogs of ligaments. Sergey Arkhipov refined the concepts of the biomechanics of the hip joint in vertical poses and during walking. He established the role of the ligament of the head of femur, ligamentum capitis femoris (LCF), in the pathogenesis of coxarthrosis and formulated a previously unknown general biological regularity – "The Law of Bioinduction". The author suggested a mathematical apparatus for calculating the dynamics of biological processes in living systems.

Sergey Arkhipov the author of six monographs, a dissertation for a candidate of medical sciences, three patents, and eight positive decisions on patent issuance, sixty articles and conference abstracts, forty patent applications. For more accurate positioning in the scientific community, he used the pseudonym S.V. Arkhipov-Baltiysky in some publications.

Scientific interests of the author include: the significance of the LCF for the musculoskeletal system; diagnosis, and treatment of diseases of the hip joint; morphomechanics; biomechanics of human and animal locomotion; modeling of joint function; development of artificial joints, and methods of hip ligament repair; biomorphic robotics.

With sincere respect to you,

Sergey Arkhipov

Article by Walmsley T. A note on the retinacula of Weitbrecht (1916). The author discusses the embryonic development and relationships of the ligamentum capitis femoris (LCF) in humans and animals. A NOTE ON THE RETINACULA OF WEITBRECHT. By THOMAS WALMSLEY, M.B., Senior Demonstrator in Anatomy, University of Glasgow. The synovial membrane of the hip-joint is in extent and attachment similar to that of other diarthroses, but the retinacula of Weitbrecht (or ligaments of Stanley) lend to it a special interest. These retinacula are readily recognized on the interior of the capsule as flattened bands passing inwards towards the margin of the head of the femur from the attachment of the peripheral capsule. The following description of their constitution may be selected as expressive of current opinion. The retinacula are arranged in three groups, superior, middle, and inferior: structurally, they are synovial covered capsular reflections: morphologic...

1914JonesFW_MorrisH

We are publishing a chapter from the fifth edition of «Morris's Human Anatomy» (1914). A significant portion of it is dedicated to the ligamentum capitis femoris (LCF). The original text has been edited by Wood Jones. Particularly notable are the illustrations depicting the LCF. Some of them are improved drawings by the first author ( 1879MorrisH ). Quote pp. 276-284 1. THE HIP-JOINT Class. — Diarthrosis. Subdivision. — Enarthrodia. The hip is the most typical example of a ball-and-socket joint in the body, the round head of the femur being received into the cup-shaped cavity of the acetabulum. Both articular surfaces are coated with cartilage, that covering the head of the femur being thicker above where it has to bear the weight of the body, and thinning out to a mere edge below; the pit for the ligamentum teres is the only part uncoated, but the cartilage is somewhat heaped up around its margin. Covering the acetabulum, the cartilage is horseshoe-shaped, a...

1861HoldenL

Fragments from the book Holden L. Human Osteology (1861). The author discusses the attachment and anatomy of the ligamentum capitis femoris (LCF) . 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 pp. 1 66-167 Acetabulum. Lastly, we come to the "acetabulum." This is so named from its resemblance to an ancient vinegar cup. Observe its great depth and hemispherical form adapted for the secure lodgement of the head of the thigh-bone, and for more or less movement in any direction. It looks downwards and outwards so as to transmit the weight of the trunk directly on to the head of the thigh-bone; and the upper or iliac portion of it is by far the thickest and strongest, since it has to support the whole weight of the trunk in the erect posture. All these points are of interest, because they are characteristic of the human skeleton. There are two notches in the margin or "br...

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. [ii] Introduction According to Rabbinic Judais...

Fragments from the book Kulmus JA. Tables anatomiques (1734). The author briefly writes about the anatomy, properties and attachment of the ligamentum capitis femoris (LCF). There are known translations of the treatise into Latin ( 1732KulmusJA ) and French ( 1734KulmusJA ). Quote p. 51 [Deu] Translation [Eng] с . In the upper part of the head there is a recess in which the round ligament is attached. Quote p. 54 [Deu] Translation [Eng] 2.)
