1922LeeserI

A fragment of the Book of Genesis tells about the journey of the family of Patriarch Jacob from Charan to Canaan (Gen. 31:1 – 33:20). The translation into English from of the Masoretic Hebrew text of the Torah was done by Isaac Leeser ( 1922 LeeserI ). «Most scholars agree that the texts now found in Genesis began to be written down sometime after the establishment of the monarchy in Israel in the tenth century BCE» (1992SuggsMJ_MuellerJR). A selected passage from an ancient work mentions for the first time in history the injury of the ligamentum capitis femoris (LCF) of a person is mentioned (Gen. 32:26,33). In the original Hebrew source this anatomical element is referred to as «גיד» (gheed, gid) ( Bereshit 32:33 ; 1923, 2004PreussJ; 2019ArkhipovSV_SkvortsovDV ; 2020ArkhipovSV_ProlyginaIV ). This term was recorded in writing long before Hippocrates of Kos (V-IV cent. BCE) who used the concept «νεῦρον» to designate LCF (1844LittréÉ). It is not known...

ILIOTIBIAL TRACT & LCF

ILIOTIBIAL TRACT & LCF There is an opinion that the iliotibial tract, like the ligamentum capitis femoris (LCF), provides pressing of the acetabulum to the lower surface of the femoral head. I think that this is not true. The tract is located above and lateral to the center of rotation of the hip joint. Its force vector, like the force vector of the abductor group of muscles, presses the acetabulum to the upper part of the femoral head, which increases the load on it. The ligamentum capitis femoris acts in the opposite direction. Below is a diagram for a single-support position. #ligamentum_teres #hip #biomechanics #ligamentum_capitis_femoris Publication in the facebook group 04/12/2025. ...

Set of Classifications

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) (1954 ГаевскаяЛИ ). 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 ( 1963 КовановВВ _ ТравинАА ). The development of arthroscopic surgery has made it possible to i...
