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.

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 article Sutton JB. Ligaments: Their Nature and Morphology (1884). The author discovered that in the ostrich the ligamentum capitis femoris (LCF) was not continuous with the ambiens muscle, but with a muscular slip which ran parallel with the-muscle, and ended in the adductor mass. This publication develops the theme of article 1883SuttonJB . Quote pp. 228-229 I must now pass on to consider certain ligaments of the appendicular skeleton, commencing with some additional remarks on the ligamentum teres. The Journal of Anatomy and Physiology, vol. xvii January 1883, contains a short article on the ligamentum teres, in which I have endeavoured to point out that many ligaments are the tender of muscles which were originally in relation with the joint; but the parent muscle has either formed new attachments or become obsolete, whilst the tendon remains as a passive element in the articulation. In addition to the ligamentum teres the following structures ...
