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

Vertebrates

VERTEBRATES According to the molecular clock, a specific method for dating phylogenetic events, vertebrates (Vertebrata) separated from arthropods (Arthropoda) 976±97 Ma (2004HedgesSB_ShoeJL). The latter began to dominate in species diversity with the Cambrian burst of radiation, which occurred 520 Ma (2010EdgecombeGD). This ratio in the fauna of the Earth is still preserved. Approximately 525 Ma, the phylum Chordates separated from the group of bilaterally symmetrical animals (1995ChenJY_ZhouGQ). In turn, the evolution of chordate organisms led to the formation of the first vertebrates at least 500 Ma, from which the jawed mouths 450-400 Ma descended, becoming the ancestors of the placoderms or "armored" fish (Placodermi) (1979 НаумовНП _ КарташевНН ).

INFERIOR PORTAL FOR HIP ARTHROSCOPY: A PILOT STUDY PART 1. Background and Hypothesis Arkhipov S.V., Independent Researcher, Joensuu, Finland Abstract: The article presents, theoretically and graphically substantiates the technique of a new arthroscopic approach to the central compartment of the hip joint. It is proposed to introduce the optical system of the arthroscope from below through the acetabular notch without traction. Similar approaches were used for puncture, arthroscopy, arthrography, and arthrotomy of the hip joint. Diagnostics using the described lower portal will exclude complications caused by distraction of the leg and compression of the perineal support during surgery. CONTENTS PART 1.
