General Classification of LCF Pathology

Version: 20240420

Annotation

Analysis of literature data and our own morphological observations allowed us to propose a General Classification of LCF Pathology.

Introduction

In Russia, the initial attempts to classify pathology of the ligamentum capitis femoris (LCF) were made by morphologists. L.I. Gaevskaya distinguished three types of LCF: 1) long and thick (length 41–51 mm, thickness 5 mm), 2) short and thin (length 10–20 mm, thickness 1 mm), 3) long and of small thickness (length 43–45 mm, with a thickness of 3 mm, and length 28–30 mm with a thickness of 4–5 mm) (1954ГаевскаяЛИ). V.V. Kovanov, A.A. Travin identified three varieties of histological structure of LCF: 1) with a predominance of loose connective tissue; 2) with a predominance of dense connective tissue; 3) with a uniform distribution of loose and dense connective tissue (1963КовановВВ_ТравинАА).

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 (1997GrayAJ_VillarRN; 2001RaoJ_VillarRN; 2010CerezalL_Pérez-CarroL; 2011BotserIB_DombBG; 2015SalasAP_O'DonnellJ M; 2017DevittBM_O'DonnellJM; 2018O'DonnellJM_AroraM). 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 (2020ArkhipovSV), as well as a Classification of Functions of the Ligamentum Teres (2020ArkhipovSV). The classification is intended to systematize pathology of LCF, assist in the development of general approaches to its description, registration, analysis, and treatment.

LCF pathology may be caused by local processes and injuries, as well as by diseases of the entire body, individual organs, or systems. Due to this, the systematic classification of all possible changes is challenging. In our collection, we have used terminology accepted in medicine and biology, applying term elements from various classifications: systematic, histological, morphological, traumatological, topographic, and functional.

The Solar System

The Solar System As a result of a mysterious catastrophic event about 13.8 billion years ago, the Universe was formed (2012HawkingS; 2020AghanimN_RoudierG). In it, giant cloud-like accumulations of plasma, molecules and dust became the points of star formation (2011MurrayN). A series of their generations, igniting, functioning and collapsing, led to the appearance of various chemical elements through staged reactions of nuclear fusion (1998IshkhanovBS_TutynIA). The Sun was born for at least ten million years by compressing a concentration of molecular gas and parts of the most ancient stars (2010HanslmeierA). As a result, 4.5682-4.567 billion years ago, the Solar System self-organized, at the dawn of its life consisting of a central luminary and a protoplanetary gas and dust disk (2013HazenRM). At least the oldest meteorite inclusions were fused 4.568-4.565 billion years ago, and at most three million years later, accretion of chondrite globules occurred (1995AllègreCJ_GöpelC). T...

344-411Rufinus Aquileiensis

A fragment of the manuscript of the translation of Josephus Flavius' Antiquities of the Jews ( Ἰουδαϊκὴ ἀρχαιολογία / De antiquitate iudaica) into Latin by Rufinus Aquileiensis. The translator worked approximately between 344 and 411 in the Roman Empire. His work was rewritten between 1150 and 1199 in Northern France. In Josephus's translation of Antiquities of the Jews, ligamentum capitis femoris (LCF) is referred to as «neruum». The selected fragment deals with the LCF of an animal and discusses a biblical episode of its damage in a human. See our commentary at the link: 344-411Rufinus Aquileiensis [Rus].
